CoppeliaSim V4.4.0 (not yet released)
Fixed several bugs. Thanks to Pranav A. Bhounsule, Amirhossein Afkhami Ardekani, Roman Horshkov, Volker Kühn, Artem Shishkin and Davide Scorza for noticing them or helping to resolve them
sim.ruckigPos, sim.ruckigVel, sim.moveToConfig and sim.moveToPose can now also be used for non-symmetric velocity/acceleration profiles, via the sim.ruckig_minvel and sim.ruckig_minaccel flags
The ZeroMQ remote API is now supported in following languages: Python, c++, Matlab, Octave, Lua and Java
Capsule primitives are now also supported
Kinematic joints can now also be directly driven via sim.setJointTargetPosition and sim.setJointTargetVelocity, using maximum velocity, acceleration and jerk constraints, for a specific motion profile
Dynamic joints now have distinct and more clearly defined control modes: free, force/torque, velocity, position, spring and custom.
Added sim.broadcastMsg, which allows to easily broadcast a message to all scripts
Added a point sampler add-on, that allows to extract 3D poisitions and normal vectors from the mouse cursor
Added a scene demonstrating texture modification to simulate a vehicle's trace: scenes/mobileRobotVisualTraces.ttt
Added a model of the ABB YuMi: Models/robots/non-mobile/ABB YuMi.ttm
Added a model of the Mirobot: Models/robots/non-mobile/Mirobot.ttm
Added a model of a generic tray: Models/equipment/generic tray.ttm
Added a model of a generic external wall: Models/infrastructure/walls/external wall.ttm
CoppeliaSim V4.3.0 (January 27th 2022)
Fixed several bugs. Thanks to Nathan Kocherhans, René Simon, Yongdong Wang, Andrés Faíña, Eric Rohmer, Davide Scorza, Jovan Sumarac, Luigi Ascione, Cameron Kabacinski, Rui Li, Patrick Grüner, Andrés Faíña, Michal Mareš, Kat Styles Wood, David Paulius and Alex Wuqi Zhang for noticing them or helping to resolve them.
Python is now also supported next to Lua, as a programming language for CoppeliaSim scripts. Both operate in almost the same fashion, except for small differences. See also the example scenes scenes/simplePythonExample.ttt, scenes/controlTypeExamples/controlledViaScript.ttt and scenes/trajectoryAndMotion/ruckigOnlineTrajectoryGeneratorExample-pythonAndLua.ttt
Objects are now identified via a path and an alias, instead of a unique object name, as was the case in previous versions: this allows for a safer and more flexible object access, by specifying absolute or relative paths, e.g. sim.getObject("./descendentObject"). This also means that object aliases (i.e. formerly names), do not need to be unique anymore. See also sim.getObjectAlias and sim.setObjectAlias.
Added a plugin wrapping the Ruckig Online Trajectory Generation library, courtesy of Lars Berscheid. It acts as a drop-in replacement for the Reflexxes Motion Library type 4, and thus also offers the jerk limitation functionality. Functionality is available via sim.ruckigPos, sim.ruckigVel, sim.ruckigStep and sim.ruckigRemove.
Added a WebSocket interface plugin.
Added a remote API based on ZeroMQ, currently however only fully implemented in Python and C++. Compared to the legacy remote API, it is very easy to use, lightweight, and supports the exact same API functions that are availabe via scripts: this includes all regular API functions (i.e. sim.* -type functions), but also all API functions provided by plugins (e.g. simOMPL.*, simUI.*, simIK.*, etc.)
Added several new callback functions: sysCall_event and sysCall_ext. sysCall_event in particular allows to keep track of most changes happening in a CoppeliaSim scene, and allows to easily implement external renderers, etc. See also next item.
Added a web-browser based front-end.
Added sim.registerScriptFuncHook, which allows to set up function hooks to be executed before or after a specific function, namely also (system) callback functions.
Object's renderable flags are now ignored by vision sensors: instead, vision sensors will render object in the same way as do cameras, by only taking into account their visibility state: this ends some confusion, but can lead in some situations to a different behaviour and result. Flexibility is however still guaranteed, with the ability to use a collection as renderable entity, which can override object's visibility states.
Added an add-on that allows to record animations from any selected object/model: Animation capture
Added sim.generateTextShape and an add-on that allows to generate and edit 3D text: 3D text generator. The add-on is courtesy of Mechatronics Ninja
Added an add-on that can import floor-plan images to 3D shapes: Floor plan importer.
Added an add-on that allows to quickly check for self-collisions, collisions with the environment, or collisions between two entities: Collision check.
Added an add-on that allows to quickly measure distances between an entity and the environment, or between two entities: Distance check.
Added an URDF export add-on: URDF exporter.
Added a model of the Franka Emika gripper, courtesy of Alexander Oliva
Added sim.moduleEntry that allows to handle menu entries in the Modules tab. When selected, the corresponding script will have its sysCall_moduleEntry callback function triggered.
Added sim.getShapeBB and sim.setShapeBB to be able to scale shapes more conveniently
Added the possibility to transform/distort vision sensor images via a function using pixel remapping: simVision.distort. See also the related demo scene in scenes/vision/imageProcessingDemo2.ttt
Added an example model of a Stewart platform: Models/robots/non-mobile/Stewart platform.ttm
Added an example scene of IK and obstacle avoidance: Scenes/kinematics/obstacleAvoidanceAndIk.ttt
Added an example scene of a mobile robot doing path planning: Scenes/pathPlanning/mobileRobotPathPlanning.ttt
Added an scene that illustrate's the relationship of CoppeliaSim's Euler angles convention (alpha-beta-gamma) and the yaw-pitch-roll Euler angles convention: Scenes/eulerAngles.ttt
Added an example scene illustrating IK movement via the remote API: scenes/messaging/ikMovementViaRemoteApi.ttt. Related Python scripts can be found in programming/zmqRemoteApi/clients/python/ and in programming/remoteApiBindings/python/python/
Added a simple button-click action tool: Models/tools/button action tool.ttm
Added a Qt QML plugin.
Added an IGL plugin, for boolean operations on shapes.
Added a subprocess plugin, for launching and handling subprocesses.
CoppeliaSim V4.2.0 (April 6th 2021)
Fixed several bugs. Thanks to Adrian Schoisengeier, Mathias Thor, Francisco Marin, Nikita Aigner, Charles Han, Shai Levy, Bobovsky Zdenko, Salvatore Sessa, Jakob Ambsdorf, Hayato Amaike, and Kevin Thomas for noticing them or helping to resolve them.
All script types now support threaded or non-threaded operation. Threaded operation is handled via coroutines that are preemptively interrupted by CoppeliaSim. Except for its code, there is no difference anymore between a threaded and non-threaded script. Old threaded child scripts are still supported for backward compatibility, but CoppeliaSim will try to automatically convert them. If this is not desired, adjust value keepOldThreadedScripts in system/usrset.txt.
Switched from Lua 5.1 to Lua 5.3. Backward compatibility should normally be maintained, except maybe for old Lua modules you might be using. If this is the case, update those module to their Lua 5.3 counterparts. Read also about the language incompatibilities introduced in Lua 5.2, and the language incompatibilities introduced in Lua 5.3. Additional backward compatibility code can be communicated to us and added to lua/sim.lua.
The ROS2 interface is now also supported on Windows.
Since this release, static IK groups (i.e. created via the GUI) are deprecated in favor of dynamically created IK groups, which offer much more flexibility. Read more about the kinematics functionality here.
Added the convenience functions simIK.addIkElementFromScene, simIK.applyIkEnvironmentToScene, simIK.applySceneToIkEnvironment, allowing to quickly generate an IK element from a kinematic chain in the scene, and to perform/apply calculations to it. All scenes have been adjusted to use above convenience functions. As simple example can be seen in scenes/kinematics/simpleIkGroupWithSimpleIkElement-undamped.ttt
Added simIK.duplicateEnvironment: useful when operating on an IK environment while leaving the original environment unchanged. Also added simIK.save.
Kinematic example scenes in folder kinematics have been reworked and simplified.
Added simIK.generatePath and a related demo scene: scenes/kinematics/ikPathGeneration.ttt
Rewrote the inverse kinematics tutorial.
Rewrote and reorganized large parts of the user manual.
Since this release, static collections (i.e. created via the GUI) are deprecated in favor of dynamically created collections, with new API functions. This results in much more flexibility. Read more about collections here.
Since this release, static collision objects (i.e. created via the GUI) are deprecated in favor of sim.checkCollision. Read more about collision detection here.
Since this release, static distance objects (i.e. created via the GUI) are deprecated in favor of sim.checkDistance. Read more about distance calculation here.
Since this release, graph streams and curves created via the GUI are deprecated in favor of streams/curves created and manipulated via new API functions. This allows a much more flexible and precise control of graphs. Read more about graphs here.
Since this release, path objects are implemented in a generic manner, via a pseudo path objects. This allows much more flexibility. Read more about paths here, and have a look at the simple example scene scenes/movingAlongAPath.ttt.
Added a CoppeliaSim linear algebra library.
Added a ZeroMQ interface plugin.
Added new conveyor models, allowing to easily create conveyor systems of any size/shape. See models in Models/equipment/conveyors.
sim.getShapeMassAndInertia and sim.setShapeMassAndInertia are deprecated, and replaced by sim.getShapeMass, sim.setShapeMass, sim.getShapeInertia and sim.setShapeInertia.
Added a new demo scene illustrating smooth movement profiles in forward and inverse kinematics mode: kinematics/smoothMovementsInFkAndIk.ttt
Updated the OMPL plugin to use the OMPL library version 1.5.0
Added simIK.getAlternateConfigs and sim.getAlternateConfigs, to be used in conjunction with simIK.getConfigForTipPose, when dealing with manipulators that have joint ranges larger than 360 degrees, to generate alternative configurations.
Added several path-related API functions, including sim.generateTimeOptimalTrajectory that allows to generate time optimal trajectories (i.e. trajectories that respect velocity and acceleration constraints), based on the TOPP-RA library. A demo scene related to that can be found in scenes/trajectoryAndMotion/pathToTrajectory.ttt.
Added a SVG widget for the CustomUI plugin. Content can be loaded from file, from XML string, or embedded in the UI XML.
sim.rmlMoveToJointPositions and sim.rmlMoveToPosition are deprecated in favor of sim.moveToConfig and sim.moveToPose, which feature a callback mechanism for maximum flexibility.
Added following API functions: sim.isDynamicallyEnabled, sim.getJointDependency, sim.changeEntityColor and sim.restoreEntityColor.
Following Docker image is available for running CoppeliaSim in a container: docker-image-coppeliasim
The default scene will now pause simulation when a script error is raised.
Added an additional dynamics configuration mode that performs smaller dynamics steps and/or does more calculation iterations. Went from [very accurate, accurate (default), fast, very fast, custom] to: [very accurate, accurate, balanced (default), fast, very fast, custom].
The Windows installer/uninstaller can now silently operate by invoking it with following command-line arguments: /silent /hide /[silent]=true
CoppeliaSim V4.1.0 (July 21st 2020)
Fixed several bugs. Thanks to Jakub Turaj, Rieky Barady, Jian Ye, Jaime Boal, Mathias Thor, Pável Axel Mc Campos Peña, Filipe Rocha, Patrick Gruener, Thomas Wilmotte, Lorenzo Romanini, Pablo Bustos, Sonny Tarbouriech, Johan Relefors, Adrian Schoisengeier, Arturs Paugurs, Wei Wei, David Page, Ayush Patel, Aleksander Sil and Cameron Kabacinski for noticing them or helping to resolve them.
Switched to Qt5.15.0 and VC2019 on Windows.
CoppeliaSim's kinematics functionality (i.e. forward and inverse kinematics) is now also available via Lua scripting: this means that instead of creating and handling kinematics tasks via the GUI, one can also entirely create and handle them programmatically in a very flexible manner. Two example scenes illustrate this: scenes/kinematics/8-computingJointAnglesForRandomPoses.ttt and scenes/kinematics/9-programmaticallySettingUpIk.ttt
CoppeliaSim's collision detection and minimum distance calculation functionality on shapes, OC-Trees and point-clouds is now also available via Lua scripting: you can now also perform the same kind of calculations without the need of creating any scene object or modifying the scene content. This is illustrated in following example scene: scenes/sceneObjectIndependentGeometricCalculationExample.ttt
ROS2 Interface plugin for ROS2 Foxy Fitzroy, supports topics, services, actions, params, TF2 broadcast and image transport.
GLTF plugin can export static scene and animations in the GLTF 2.0 format. The functionality is available via the add-on menu, or via related API functions.
URL Drop plugin allows loading scene from remote locations via drag and drop (e.g. drop an URL from a browser's window).
The verbosity level (console, status bar and simple dialogs) can now be adjusted from the command line with the -v , -w and -x arguments. To output messages, plugins should now use simAddLog and scripts sim.addLog.
An optional Lua script string may be executed via the command line with the -c argument.
Added an example scene illustrating simple motor controllers: scenes/motorControllerExamples.ttt
Added an example scene illustrating how to apply inverse kinematics to dynamically enabled models/manipulators: scenes/kinematics/10-applyingIkToDynamicallyEnabledModels.ttt
Added an example scene illustrating simple usage of the Reflexxes Motion Library: scenes/reflexxesMotionLibraryExamples.ttt
Added sim.setJointTargetForce and sim.getJointTargetForce. sim.setJointForce is now deprecated.
Added sim.yawPitchRollToAlphaBetaGamma and sim.alphaBetaGammaToYawPitchRoll, to convert between those two different Euler angle representations.
The true headless CoppeliaSim library is also shipped (i.e. coppeliaSimLibHeadless.dll or similar). This is in addition to the headless mode supported via the -h command line option, which simply suppresses all GUI elements of the regular CoppeliaSim library.
Fixed a few shape export problems (i.e. normals and/or textures)
A Simulink-CoppeliaSim communication plugin is now available, courtesy of Diego Daniel Santiago.
Many CoppeliaSim video tutorials courtesy of Leopoldo Armesto.
CoppeliaSim V4.0.0 (November 26th 2019)
We discontinued development of V-REP. Instead, we focus our efforts on CoppeliaSim. CoppeliaSim is 100% compatible with V-REP (i.e. it is a fork of the V-REP project). It runs faster and has more features than V-REP. Of course will Coppelia Robotics handle V-REP support and licenses in a perfectly interchangeable manner with CoppeliaSim support and licenses.
Fixed several bugs. Thanks to Mark Hartenstein, Stephen James, Simon Birrell, Sahil Sharma, Adrian Schoisengeier, Rémi Lux, Kilian Freitag, Maël Hörz and Eric Rohmer for noticing them or helping to resolve them.
Completely rewrote the calculation routines handling collision detections, minimum distance calculations, proximity sensor simulations, OC trees and point clouds. A significant speed increase could be achieved. The routines are now grouped in the geometric plugin. The core of the geometric plugin are the Coppelia geometric routines, available for stand-alone applications.
You can now import and export XML files.
You can now from within the script editor open the API documentation for the function/constant under the mouse pointer, via the context menu.
Switched to Qt5.12.5 on all 3 platforms.
Added support for ROS 2 via ROS2Interface. See the compiledRosPlugins folder, and the ROS2 Interface source code. Have also a look at ROS 2 API and the ROS 2 tutorial.
Vision sensor filters are no longer supported. They are replaced by vision callback functions, which allow for a much more flexible operation. Old scenes are automatically updated. A demo scene illustrating the new way to handle image processing was added: imageProcessingDemo.ttt.
Added trigger callback functions for vision sensors, proximity sensors, and force/torque sensors.
Added user config callback functions, which allow implementing custom behaviour upon double-clicking user parameter icons.
Added an add-on for exporting scene content as glTF data: simAddOnGLTFExporter.lua
The OpenGL3 renderer can now also be selected as renderer for cameras, during simulation.
Added the model of the Franka Emik Panda robot, courtesy of Alexander Oliva, Marco Cognetti and Claudio Gaz.
CoppeliaSim simulations can be exported to Blender via Boris Bogaerts' CoppeliaSim-Blender-Tools.
RLBench is an ambitious large-scale benchmark and learning environment designed to facilitate research in a number of vision-guided manipulation research areas, including: reinforcement learning, imitation learning, multi-task learning, geometric computer vision, and in particular, few-shot learning. RLBench, built around PyRep and CoppeliaSim, is created by Stephen James.
Added a model of the Niryo One robot.
V-REP V3.6.2 (June 26th 2019)
Fixed several bugs. Thanks to Jacob Smith, Mohsen Moradi Dalvand, Simon Birrell, Mathias Thor, Jedrzej Orbik and Liu Dong for noticing them or helping to resolve them.
PyRep, built on top of V-REP and courtesy of Stephen James (Imperial College London), is a Python toolkit for robot learning research. Compared to the remote client approach, it displays great speed improvements since remote procedure calls or synchronization are not required. This makes PyRep the perfect solution for learning algorithms in the areas of reinforcement learning, imitation learning, state estimation, mapping, and computer vision.
V-REP now also offers shadows support with vision sensors, when rendering via the OpenGL3 renderer plugin, courtesy of Stephen James (Imperial College London). See also the updated rendererDemo.ttt scene.
The sandbox script is now loaded from system/sndbxscpt.txt at start-up, and can contain similar callback functions as add-ons.
Named command-line arguments are now supported via the -G option. Those can be queried (e.g. by plugins) via sim.getNamedStringParam.
V-REP V3.6.1 (March 15th 2019)
Fixed several bugs. Thanks to Julian Mayer and Boris Bogaerts for noticing them or helping to resolve them.
Switched to Qt5.12.1 on all 3 platforms
Added API functions simApplyTexture, sim.setJointDependency and sim.getStackTraceback.
The shape import/export functionality is now handled by a V-REP Plugin (simExtAssimp), based on the Assimp library. See here for the new API functions.
URDF and SDF files are now loaded with textures (if present)
V-REP V3.6.0 (February 15th 2019)
Fixed several bugs. Thanks to Leon Masopust, Michael Tong, Zhengxing Yang, Lenka Pitonakova, Thomas Gurriet, Hervé Frezza-Buet, Justus Rijke, Stefan Müller, Julien Lechalupe, Tristan Gahler, Robert Peck, William Jones, Benjamin Erdemann, Ulrich Viereck, Joachim Haensel and Justus Rijke for noticing them or helping to resolve them.
Script execution/calling order has been adjusted, for a more consistent and overall logical behaviour. This may have an impact on how a simulation runs in certain situations.
Dynamics callback functions have been implemented and are supported in child scripts and customization scripts.
Added a system callback function for customization scripts and add-ons that allows, during simulation, to control the execution of the main script: sysCall_beforeMainScript. This is useful to easily implement step-by-step simulation, or to easily synchronize the simulation with an external application.
Added a simple script debug functionality that allows to monitor function calls and watching variables.
The Lua commander now has dynamic variable completion, history, explicitely prints any variable, etc. Type help() for details.
Added following API function: sim.getPersistentDataTags.
The Open Mesh plugin for V-REP now uses the latest OpenMesh library (V6.3) on all 3 platforms
Added a MessagePack module for Lua: lua-MessagePack, courtesy of Francois Perrad.
Added a MessagePack encoder/decoder for C/C++: msgpack-c, courtesy of Takatoshi Kondo and several others.
Added a MessagePack encoder/decoder for Matlab: matlab-msgpack, courtesy of Bastian Bechtold.
Added a MessagePack encoder/decoder for Java: msgpack-java, courtesy of Sadayuki Furuhashi and several others.
Added a CBOR encoder/decoder for Lua: Lua-CBOR, courtesy of Kim Alvefur.
Added sim.getRandom, math.random2 and math.randomseed2 in order to provide individual random number generators for each script (math.random and math.randomseed share the same generator, independent of which script is calling)
The script editor functionality is now provided via a plugin: simExtCodeEditor. It allows to easily search/replace, do/undo, jump to specific functions, restart a script, offers non-modal customization script edition, etc. Code included via the require directive can automatically be opened and modified via the popup menu. You can temporarily revert to the old script editor functionality by adjusting variable useOldCodeEditor in file system/usrset.txt.
Added sim.textEditorOpen, sim.textEditorClose, sim.textEditorShow and sim.textEditorGetInfo
A VR interface for V-REP was developed by Boris Bogaerts. It can visualize any V-REP scene in steamVR (openVR) compatible VR devices and return user manipulations to V-REP. Installer files are available here (no compilation required, windows only). Instructions on how to use the interface are provided here.
A ROS-enabled e-puck, courtesy of Andrei Florea and Catalin Buiu, was added to the model library. More details can be found here.
V-REP V3.5.0 (February 6th 2018)
Fixed several bugs. Thanks to Steffen Hemer, Fangyi Zhang, virgile Daugé, Riccardo Spica, Filipe Rocha, Jacob Huesman, Matthew Veres, Robert Lang and Florian Golemo for noticing them or helping to resolve them.
Switched to Qt 5.9.0 LTS on all platforms.
From within a script, print() now prints to the status bar, instead of the console. This can be reverted with print=printToConsole. printf() is now also supported. Both, print and printf will now also print the content of tables.
Added a Lua commander plugin (read-eval-print loop), that adds a text input to the V-REP status bar, which allows entering and executing Lua code on the fly, like in a terminal. The code can be run in the sandbox script, or any other active script in V-REP
Moved all the source code items related to V-REP to github.
Switched to a cleaner way of calling script code, by using predefined functions (e.g. sysCall_init, sysCall_actuation, etc. Scripts should now contain nothing else than functions anymore. The old way of calling scripts is however still supported for the sake of backward compatibility (but make sure not to mix both methods).
New joint callback functions have been implemented and are supported in child scripts and customization scripts. The old joint control callback script functionality should not be used anymore and is not accessible anymore via the GUI, but is still operational (you can temporarily make it accessible again via enableOldJointCallbackScriptEdition in system/usrset.txt)
A new contact callback function has been implemented and is supported in child scripts and customization script. The old contact callback script functionality should not be used anymore and is not accessible anymore via the GUI, but is still operational (you can temporarily make it accessible again via enableOldCustomContactHandlingEdition in system/usrset.txt)
New widgets and API functions were added to the custom UI.
Updated the content of v-repNotepad++.zip, which contains all V-REP-related calltips and syntax highlighting keywords for Notepad++.
Added sim.getShapeViz, that allows to retrieve a shape's mesh and texture information
Added a tool that allows to step through a simulation by triggering each individual simulation step. Can also be used in replacement of the remote API or ROS synchronous mode. The tool is located in Models/tools/simulation stepper tool.ttm.
Added a vision sensor model that extracts 3D positions from blob detections: Models/components/sensors/Blob to 3D position.ttm.
Added a plugin that wraps the LibICP (Library for Iterative Closest Point Matching, by Andreas Geiger)
Added a plugin that wraps the OpenCV library, offering basic image processing and drawing functionality
Broke compatibility of the simExtSurfaceReconstruction_reconstruct API function, which was replaced with simSurfRec.reconstruct_scale_space.
Added support for shared memory communication in the legacy emote API. The code is courtesy of Benjamin Navarro. By specifying a negative port number, shared memory will be used instead of socket communication.
Added following API functions: sim.executeScriptString, sim.getApiFunc, sim.getApiInfo, sim.setModuleInfo and sim.getModuleInfo.
A Lanelet plugin for V-REP was developed by Cándido Otero, available here.
Modern Robotics: Mechanics, Planning, and Control, a new textbook by Prof. Kevin M. Lynch and Prof. Frank C. Park is available for free download here, and also available for purchase as hardback copy. Several V-REP examples and scenes are available here.
V-REP V3.4.0 (April 6th 2017)
Fixed several bugs. Thanks to Sven Schweigler, Nicola Battilani, Mark Edmonds, Benno Timmermann, Cándido Otero Moreira, Graeme Neff Wilson, Justin Yim, Allen Zhu, Leo Koppel, Ravi Prakash Joshi, Sina Radmard, Sai Vemprala, James Barger, Gonzalo Casas, Metehan Doyran, Arif Rahman and Jason Cachrane for noticing them or helping to resolve them.
For the Windows version of V-REP, switched to Qt 5.6.2, MSVC2015 and 64bit. Make sure to desinstall previous V-REP versions explicitely in folders program files (x86)/V-REP3/V-REP_PRO, program files (x86)/V-REP3/V-REP_PRO_EDU and program files (x86)/V-REP3/V-REP_PLAYER: execute V-REP_*_Setup_*.exe in those folders. Then remove folder program files (x86)/V-REP3. Prior to that you should backup an existing license key.
The Vortex plugin is now based in the free version of the Vortex engine: Vortex Studio. The user will however have to download/install Vortex Studio, and register with CM Labs, in order to enable the vortex plugin for V-REP.
The Vortex plugin now has the multithreading option turned off by default, since this provides better stability and faster simulation speeds for typical V-REP scenes. This can however still be turned on in the dynamics engines general properties.
Reworked the position dialog and the orientation dialog.
Added various API functions: sim.transformBuffer.
Added a reconfigurable model of the Ragnar robot: Models/robots/non-mobile/ragnar.brm
Added a new command line option allowing to disable specific GUI items.
Material properties (used by the physics engines) are not shared among shapes anymore, since this lead to confusions and apparently strange behaviours, and material pollution. Now, every shape has its own set of material properties. Material properties can be copied from another shape, or set to a predefined type via sim.setShapeMaterial.
Custom UIs can now display plots, be modal, etc. A few bugs have also been fixed.
2D visualization of newly added graph objects is now based on the custom UI plot functionality.
Added following API functions to the ROS Interface: simROS.getTime, simROS.hasParam, simROS.searchParam, simROS.deleteParam, simROS.getParamBool, simROS.setParamBool, simROS.getParamInt, simROS.setParamInt, simROS.getParamDouble, simROS.setParamDouble, simROS.getParamString, simROS.setParamString.
Added an improved version of the playback tool: Models/tools/playback tool.ttm: it operates faster, requires less memory, and uses the custom UI plugin.
Added a tool for viewing custom data blocks attached to objects or a scene: Models/tools/custom data block reader.ttm.
Added an API function, based on the CGAL library, that allows to extract a shape from a point cloud: simSurfRec.reconstruct_scale_space. A model using that function is available here: Models/tools/surface reconstruction.ttm
Added a model allowing to import a point cloud from a *.xyz file format: Models/tools/point cloud importer.ttm
Added an option to record the desktop, including overlapping dialogs, instead of only the simulation window in the video recorder.
The Reflexxes Motion Library type 4 plugin (RML4 plugin) is no longer distributed. Instead, a RML2 plugin is distributed. This means that jerk limitation is no longer supported. The former RML4 plugin is however still functional (i.e. simExtRML4.dll/libsimExtRML4.so/libsimExtRML4.dylib): simply replace or place it alongside the RML2 plugin in the V-REP main folder.
The OpenGl-based custom UI edition capability was removed, since that functionality is not as flexible and elegant as the Qt-based custom UIs. OpenGl-based custom UIs will however still be functional, and you can enable edition capability again with variable enableOpenGlBasedCustomUiEditor in file system/usrset.txt.
Added a simulation model of the UR3 robot: Models/robots/non-mobile/UR3.ttm.
CoppeliaSim Edu / V-REP PRO EDU can now read scene and model files from XReality. CoppeliaSim Pro / V-REP PRO can now read/write scene and model files from/for XReality.
Added following two API functions: sim.setReferencedHandles and sim.getReferencedHandles.
Added a model of Marty the Robot (in Models/robots/mobile/ ), courtesy of Sandy Enoch of Robotical Ltd. and Alejandro Bordallo. Marty is designed to work with the official ROS Marty stack.
A swarm controller for the teleoperation of robot swarms in a V-REP based simulation environment, courtesy of the robotics and control systems laboratory of the Sapientia Hungarian University of Transylvania, is available here.
Added a JSON module for Lua: dkjson, courtesy of David Heiko Kolf.
V-REP V3.3.2 (August 29th 2016)
Fixed several bugs. Thanks to Hao Wang, Robert Lang, Riccardo Spica, Matias Nitsche, Sven Knüppel, Ndivhuwo Makondo, Yu Zhang, Paul Santiago Tumbaco Casa, DeKita G. Moon, Rodrigo Moreno Garcia, Federico Ferri and Arjun Narayanan for noticing them or helping to resolve them.
Improved the point cloud functionality. You can now specify a minimum distance tolerance which is used to avoid duplicate points. The tolerance can be specified in the point cloud properties dialog, or via sim.insertPointsIntoPointCloud or sim.insertObjectIntoPointCloud.
Added a simulation model of the Sawyer robot: models/robots/non-mobile/Sawyer.ttm. The original CAD data is courtesy of Rethink Robotics.
Added an infinite floor model, that allows to mimic an infinite floor: Models/infrastructure/floors/infiniteFloor.ttm.
Added the paths <currentScenePath> and <V-REPInstallationPath/lua> to the Lua path variable of all scripts.
Improved the custom UI plugin: widgets can now be enabled/disabled, and event messages supressed when setting a widget value. An editing finished event can now also be generated for edit boxes.
Added a G-code interpreter that can be found in lua/gcode.lua. A demo scene was also added: Scenes/gCode.ttt.
Added several new API functions: sim.openTextEditor, sim.packTable and sim.unpackTable.
Added a first version of a SDF format importer plugin, courtesy of Federico Ferri.
An SDL2 library plugin, courtesy of Tobias Benz, is available here.
V-REP V3.3.1 (May 17th 2016)
Fixed several bugs. Thanks to Ahmed Yacine, Korolyov Alexei, Graeme Neff Wilson, Daniel Angelov, Scott Hissam, Mohammed Talha and Mark Fink for noticing them or helping to resolve them.
Added a new ROS plugin (ROS Interface), which supports most standard ROS messages, and which naturally duplicated the ROS C/C++ API. We highly recommend to use this new ROS interface, rather than the previous one (RosPlugin). Both however can run side-by-side. The scene controlTypeExamples.ttt was adjusted and now includes an additional robot, which is controlled via the new ROS Interface. A new scene was created that also illustrates the new ROS Interface: rosInterfaceTopicPublisherAndSubscriber.ttt.
Added a new object type: OC trees. They represent a spatial partitioning based of voxels and can be used for various purposes (e.g. simplified shape representation, occupancy grid/space, etc.). OC trees are collidable, measurable and detectable. New API function related to OC trees are listed here.
Added a new object type: point clouds. They represent points stored inside of an OC tree-like data structure and can be used for various purposes (e.g. point storage and manipulation, etc.). Point clouds are collidable, measurable and detectable. New API function related to point clouds are listed here.
Added a new scene (collisionDetectionDemo.ttt), which illustrates V-REP's collision detection capabilities on dummies, shapes, OC trees and point clouds.
Added a new scene (minimumDistanceCalculationDemo.ttt), which illustrates V-REP's minimum distance calculation capabilities on dummies, shapes, OC trees and point clouds.

Added two new scenes: octreeGenerationDemo.ttt and navigationWithinAPointCloud.ttt.
Added a new OMPL plugin function, that allows to specify several goal states for a given task: simOMPL.addGoalState. Following demo scenes now use this new functionality: motionPlanningDemo1.ttt, motionPlanningServerDemo.ttt and motionPlanningAndGraspingDemo.ttt.
Added a new type of custom user interface, based on a plugin and Qt: Qt-based custom UIs. A demo scene can be found at scenes/customUI-QtBased.ttt.
Added a menu item that allows to compute the inflated convex hull of a shape. This is useful in order to generate simplified collision object that are slightly bigger than their original. The menu item is located at [Menu bar --> Add --> Inflated convex hull of selection...]
Added stack functions that allow to hold almost any type of data or data structure. This is useful for flexible communication between plugins and scripts. Following new API functions now use stacks: simCallScriptFunctionEx and simRegisterScriptCallbackFunction.
Added setter and getter API function for the physics engine properties.
Added a newer version of the Bullet engine (i.e. V2.83). The new version offers now 4 different solver types: sequential impulse, NNCG, Dantzig, and projected Gauss-Seidel. All physics engine's plugins have been reworked.
Added two additional spherical vision sensors: they now allow to retrieve spherical RGB images, spherical depth buffers, or spherical RGB images and depth buffers: Models/components/sensors/spherical vision sensor RGB.ttm, Models/components/sensors/spherical vision sensor depth.ttm, Models/components/sensors/spherical vision sensor RGB + depth.ttm.
Reworked the Velodyne sensors, which are now using the new point cloud object. This means that sensor points can now be collidable, measurable and detectable.
Added three new API functions: sim.loadImage, sim.getScaledImage and sim.transformImage.
Added a model, allowing to start, pause, stop or step a synchronous simulation, from a ROS node. The model is based on the new ROS Interface and is located in Models/tools/rosInterfaceHelperTool.ttm

Following demo scenes are now using the OMPL plugin functionality: motionPlanningDemo1.ttt, motionPlanningAndGraspingDemo.ttt, 3DoFHolonomicPathPlanning.ttt and 6DoFHolonomicPathPlanning.ttt, motionPlanningServerDemo.ttt.
Added a new ROS service, ROS publisher type, and ROS subscriber type: simRosCallScriptFunction, simros_strmcmd_receive_data_from_script_function and simros_strmcmd_send_data_to_script_function. These are very useful when a regular API function is not immediately available in the RosPlugin, or when a succession of complex commands need to be executed locally. Have a look at the demo scene rosTopicPublisherAndSubscriber2.ttt, which illustrates the new functionality.
Improved and corrected the sim.callScriptFunction API function.
sim.loadModule and sim.unloadModule can now also be used from a script, in order to dynamically load/unload a plugin. Certain restrictions apply: in particular, if the plugin registered custom lua functions via simRegisterCustomLuaFunction without specifying the function name as functionName@pluginName, a crash might occure during the dynamic plugin unload operation.
Added an API function that allows to compute the Jacobian of an IK group.
The V-REP source code can now be compiled for headless operation, without any Qt dependency. In that case however, the vision sensors will only generate an image content when the rendering is handled via a plugin (e.g. POV-Ray or and external renderer).
Added following new API functions: sim.computeMassAndInertia and sim.getExtensionString.
Added a model of the uArm with gripper and inverse kinematic routine: Models/robots/non-mobile/uarm with gripper.ttm
A constrained optimization IK plugin for V-REP, courtesy of Andrew Hundt, is available here. Installation instructions for Linux / OSX are available here.

Added several convenience functions to morph shapes into their convex hull repesentation, to decimate shapes, and to extract a shape's inside. The functions can be accessed with [Menu bar --> Edit --> ...].
Added a new tutorial on building clean and efficient simulation models. This tutorial is a must for everyone who wishes to create his/her own models.
Simplified the BubbleRob tutorial.
Added a section about joint controllers and how to implement them within V-REP, or inside of an external application (e.g. a remote API client, or a ROS node).
Added a model of the P-Arm robot, and two of its grippers. The CAD data is courtesy of F&P Robotics. The models can be found at models/robots/non-mobile/P-Arm.ttm, models/components/grippers/P-Grip-straight.ttm and models/components/grippers/P-Grip-right-angle.ttm.
Added several simple example scenes that illustrate how to use the kinematics module. The scenes can be found in scenes/kinematics.

Switched to Qt 5.5.0 for the Windows, the MacOS and the Linux versions.
Reworked many dialogs by adapting the floating-point number display, the unit display, and removing some deprecated/rarely used items. The user interface units are now fixed to degrees, meters, seconds, kilograms, Newtons, etc. to avoid confusions.
Added an edit mode for compound shapes. This allows to edit the visual parameters of a compound shape without having to ungroup it.
Added a possibility to automatically compute the mass and inertia tensor for convex shapes in the shape dynamic properties. The algorithm is courtesy of Chris Hecker.
Added a plugin able to render ray-traced images (via vision sensors or via cameras). This will allow to perform more realistic image-based control. The plugin is based on POV-Ray and allows rendering shadows (also soft) and focal blur. The ray-tracer plugin is courtesy of Andreu Vidal. The source can be found here.
Added a plugin for support of the Newton Dynamics engine. The plugin is currently a BETA version, and will be improved for next release. The plugin is courtesy of Julio Jerez and Alain Suero.
Added a plugin that performs the rendering instead of a vision sensor or a camera. The plugin is meant as an example, and its source can be found here.
Added a scene that demonstrates the various rendering modes available in V-REP: scenes/rendererDemo.ttt.
Modified the way how V-REP interacts with the physics plugin: it is now possible to compile the Bullet, ODE, Vortex or Newton plugins separately. This will greatly simplify adding additional physics engines.
Modified the legacy remote API Python bindings, including the Python example programs. They should work fine on Python 2.x, Python 3.x and IronPython.
The OpenRTM-aist is now supported thanks to Yuki Suga. Installation instructions are given here.
Moved the Qhull functionality out of V-REP's main library, into a plugin (simExtQhull). The source code can be found here.
Moved the convex decomposition functionality out of V-REP's main library, into a plugin (simExtConvexDecompose). The source code can be found here.

Thanks to Jan Dentler, Robert Lang, Raimund Krenmüller, Cedric Pradalier, Reza Mahjourian, Anuraj Rajendraprakash, Sébastien Granges, Ángel Luis Jiménez García, Leander Hille, Pierre Rouanet, Ulrich Schwesinger, Kenichi Hara, Federico Ferri, Martin Pecka and Nicola Piccinelli for noticing them or helping to resolve them.
Added 2 classes (CLuaFunctionData and CLuaFunctionDataItem) that greatly simplify passing arguments to/from custom Lua function created in plugins. The two classes are located in programming/common and programming/include folders.
Completely rewrote the Khepera3, the MTB, and the BubbleRob plugins: they have been greatly simplified.
V-REP now supports the RRS-1 specifications via a plugin (simExtRRS1). It allows to connect and interact with all RCS modules and robots that supports the RRS-1 specifications. For an example have a look at the demo file scenes/RRS-1 demo.ttt.
Rewrote the plugin tutorial, which has become much simpler.
Rewrote the robot language integration tutorial, which has become much simpler.
The CHAI3D plugin (for interfacing a haptic device) has been completely rewritten and greatly improved, courtesy of Sébastien Granges. Visit www.chai3d.org or www.forcedimension.com for the source code of that plugin. In case it is not yet available on those websites, please contact us.

Switched to Ubuntu 14.04.1 LTS for Linux versions of V-REP.
The precompiled ROS items are now specifically meant for ROS Indigo. If you use a different version, make sure to recompile them.
Switched to Qt 5.4.0 for Linux versions of V-REP.
Improved the visual appearance of 3D objects by adjusting the way meshes are rendered. This can lead to small differences in color/lighting with previous V-REP releases. You may have to adjust the ambient light manually.
Added backtrace information output, for easier debugging of script code.
Script colors can now individually be adjusted. See the file system/usrset.txt.
Objects can now be selectively seen from a given camera or vision sensor. This can be adjusted in the object common properties.
High resolution displays (such as Retina display) are now fully supported, and should be automatically detected. You can force a different behaviour by adjusting the value of highResDisplay in the file system/usrset.txt.
Added a model of the Velodyne HDL-64E S2 Lidar: Models/components/sensors/velodyne HDL-64E S2.ttm.

Improved the embedded script editor with following new features: highlighting of all occurrences of selected word, source folding/unfolding, simple word search via the <ctrl+f> key.
External script editors can now be customized with the data in file v-rep_notepad++.zip: this allows for keyword highlighting, auto-completion and call tip display.
Improved the shape serialization routines, effectively reducing generated file sizes, mainly if they contain duplicate geometric content. The generated file format cannot be read by previous V-REP versions (prior to V-REP 3.1.3), so make sure to make backup copies.
Added a new type of embedded script: customization scripts. They are associated with scene objects (same as child scripts) and can be used to customize a simulation scene to a great extent. The main difference with child scripts is that customization scripts are running all the time, also when simulation is not running.
Added several models that demonstrate the new customization script functionality: Models/nature/terrain bump.ttm, Models/nature/Terrain.ttm, Models/nature/Tree.ttm, Models/infrastructure/other/resizable concret block.ttm, Models/infrastructure/floors/resizable floor*.ttm, Models/tools/playback tool.ttm, Models/tools/isometric scaling tool.ttm, Models/tools/name change tool.ttm, Models/tools/custom data viewer tool.ttm, Models/equipment/conveyor belts/customizable conveyor belt.ttm, Models/furniture/tables/customizable table.ttm.
Modified the way child scripts are handled in order to make them operate in a more coherent manner:
child scripts execution is now automatically cascaded (i.e. no need to explicitely call simHandleChildScript anymore).
child scripts are now executed in the actuation phase as well as in the sensing phase of a given simulation step: there is no distinction anymore with what previously used to be sensing child scripts.
script compatibility with previous file versions is guaranteed by 1) automatic child script code modification (clearly marked as such), 2) automatic main script replacement. This covers 99% of all situations, but it can happen that this automatic modification partly fails (e.g. when the main script was customized, or when explicitely executing a specific child script (previously marked as explicit handling)). In that case, contact us for assistance.
Improved the rendering speed. If compatibility issues arise, please contact us, and try to disable VBO operation here.
Improved the start-up time of certain simulation scenes, by adding a broad mode for collision detection, minimum distance calculation and proximity sensor detection: Oriented Bounding Box (i.e. OBB) data structures are now only computed on-the-fly and only when absolutely necessary. This can be visualized via [Menu bar --> Help --> Debug --> Visualize prepared OBB calculation structures].
Added 3 new API functions: sim.copyPasteObjects, sim.scaleObjects and sim.removeModel. simCopyPasteSelectedObjects, simScaleSelectedObjects and simDeleteSelectedObjects are declared deprecated.
Added project files for custom ROS plugins for V-REP (i.e. in order to support specific ROS messages of a specific robot).
Added a model of the Robotnik Summit XL robot, courtesy of Roberto Guzman: Models/robots/mobile/Robotnik_Summit_XL_140701.ttm
Improved the undo/redo functionality that now operates in a more consistent manner. Camera movements are not considered as undo points anymore. This behaviour can be adjusted via the user settings file system/usrset.txt.
The API functions sim.readCustomDataBlock and sim.writeCustomDataBlock can now also be used to attach custom data to scripts. At the same time you can now also specify whether the data should be saved during a scene or model save operation.
The vision sensor code has been optimized and vision sensors now run faster. They now can also operate in a different mode, in order to simulate the temperature of objects for instance, or in order to detect object handles.
Added several new API functions: sim.getObjectsInTree, sim.scaleObject (i.e. non-isometric scaling), sim.getShapeTextureId, sim.setShapeTexture, sim.getCollectionObjects, sim.handleChildScripts and sim.reorientShapeBoundingBox.
Added a SLAM demo based on ROS, courtesy of Leopoldo Armesto.
Added a link to a tutorial on teaching robotics with a simulator, courtesy of Prof. Renaud Detry.
Added a link to a Python quadrotor simulator, courtesy of B. Acharya, F. Gisa, and S. D. Levy.
Added a link to the TAPIR implementation of the Adaptive Belief Tree (ABT) algorithm, courtesy of Hanna Kurniawati, Dimitri Klimenko, Joshua Mun Song and Vinay Yadav.
The middle mouse button can now be deactivated in order to not react to a press action. This can be done in the user settings file in system/usrset.txt.
Added an interface model to the Arduino Esplora, located in Models/other/Arduina Esplora.ttm. The model is courtesy of Eric Rohmer.
Added a function that allows to link two dynamic joints (i.e. a force/torque applied to one will be transmitted to the other one, and vice-versa). This allows to simulate complex gear mechanisms, without the need to simulate the gear contacts. This feature is currently only supported via the Vortex plugin.
Added a demo scene that illustrates how to simulate gear mechanisms with Vortex: scenes/gearMechanism.ttt.
Changed the camera navigation method: camera rotations are now performed with the middle mouse button, instead of the right mouse button (which was, to many, confusing and not practical). The right mouse button is now exclusively reserved for pop-up menus. The previous navigation method can still be enabled via the variables navigationBackwardCompatibility and middleMouseButtonSwitchesModes in the system/usrset.txt file, but this is not recommended since this option will probably disappear in future.
Added a play back tool, that allows you to manually step through a simulation. The model file is located in Models/tools/playback tool.ttm.
V-REP V3.1.2 (June 17th 2014)
Fixed several bugs. Thanks to Matt Derry, Daniel Morberg, Andreas Kuhner, Danilo Vasconcellos Vargas, Spencer Krause, Daniel Kuhner, Luigi Ferri, Filip Jares, Michaela Richter, Matthias Schindler and Ulrich Schwesinger for noticing them or helping to resolve them.
Fixed a bug of the PID joint controller: in older V-REP versions, the I and D parameters had to be wrongly scaled in order to obtain the correct behaviour. The controller was now fixed and parameters are automatically scaled to a correct value when loading older file versions. Custom joint callback controllers will have to be adjusted manually if they make use of the I or D parameters.
The joint dynamics properties have been reorganized in order to facilitate the creation of spring-damper systems, by allowing to directly specify the spring constant K and its damping coefficient C.
Matlab versions previous to 2008a might be supported via the files located here, courtesy of Gerold Huber.
The RosPlugin was catkinized, courtesy of Arne Hitzmann and Sergi Foix.
V-REP now also supports 3D OpenGL stereo mode (for dedicated hardware, i.e. specific stereo-enabled graphic cards with corresponding monitor/device). To enable it, set a value different from 0 for stereoDist in file system/usrset.txt. The console should indicate at start-up if the mode was successfully enabled. Make sure to correctly configure your graphic card (i.e. 3D OpenGL stereo & correct stereo display mode).
Added a simulation model of the Baxter robot, including its vacuum cup and gripper tools: models/robots/non-mobile/Baxter.ttm, models/components/grippers/Baxter vacuum cup.ttm and models/components/grippers/Baxter gripper.ttm. The original CAD data is courtesy of Rethink Robotics.

Improved the OBJ file format importer.
Switched to an updated Vortex library (V6.1.2) that offers an improved contact generation.
Added a simulation model that allows visualizing the center of mass of a dynamic model: models/other/center of mass visualizer.ttm.
Added a new API function to retrieve geometric information about shapes: sim.getShapeGeomInfo.
Added a new API function that helps to make a motion planning transition from one configuration to another, by following a predefined Cartesian space path. This is useful for redundant manipulators, but also for safely driving non-redundant manipulators via IK through a singular configuration: simGetMpConfigTransition.
simRMLPosition and simRMLVelocity are declared deprecated and are replaced by following API functions: sim.ruckigPos, sim.ruckigVel, sim.ruckigStep and sim.ruckigRemove.
Added a simulation model of the Adept Quattro 650HS parallel manipulator, courtesy of Preben Hjornet: models/robots/non-mobile/Adept Quattro 650HS.ttm. The original CAD data is courtesy of Adept Technology.
Added a plugin that implements shared memory communication, courtesy of Diego Daniel Santiago. The source code, currently only running on Windows, is located here.

Added following regular API functions: sim.quitSimulator.
Added the option to run V-REP headless (without any graphical user interface (i.e. in the command line only)), as well as other command line options. The graphics libraries are still needed. A binary that doesn't rely of graphics libraries is planned.
Added a bridge to OpenCV via a plugin, courtesy of Marco Bellaccini. The files are located here.
Added a first version of a Labview interface for the legacy remote API, courtesy of Peter Mačička.
V-REP V3.0.5 (October 27th 2013)
Switched to Qt5.1.1. Many changes and refactorings were made, and are still ongoing.
Added optional support for high fidelity physics with the Vortex Studio engine. Thanks to Martin Courchesne and SimWat for their plugin implementation. The plugin will gradually be improved in order to support simulation requirements in various fields (fluids, particles, etc.).
Added a motion planning functionality, that allows to plan movement sequences of kinematic chains, in a clutered environment. The documentation on this is unfortunately not yet very exhaustive, make sure to refer to the motion planning dialog and the related API functions.
Added 3 scenes to illustrate the new motion planning functionality: motionPlanningDemo1.ttt, motionPlanningDemo2.ttt and motionPlanningDemo3.ttt.
Added a simulation model of the SICK TiM310 laser scanner: models/components/sensors/SICK TiM310 Fast.ttm

Following texture file formats are now supported: JPEG, PNG, TGA, BMP, TIFF & GIF. Thanks to Sean Barrett for his image loading routines (used for GIF and TGA).
Adjusted all default light intensities and default object colors (ambient component only) in order to be more compatible with other CAD applications. Older scenes and models will automatically adjust for that during a load operation (i.e. light intensities will be scaled by 0.675, colors by 1.5). If you do not wish for this automatic adjustment, turn variable correctColorsAndLights to false in system/usrset.txt.
Added a ROS publisher for vision sensor depth data as RGBD point cloud, courtesy of Cedric Pradalier.

Added the possibility for vision sensors to ignore their RGB or depth information. When used, this allows to accelerate vision sensor operation. Refer to the vision sensor properties.
Added two new vision sensor filters. The first allows to extract coordinates from a vision sensor depth map. This allows to create fast laser scanner models, such as models/components/sensors/Hokuyo URG 04LX UG01_Fast.ttm or models/components/sensors/3D laser scanner Fast.ttm. The second added vision sensor filter allows to track individual pixel changes, such as in the model models/components/sensors/DVS128.ttm, courtesy of IniLabs.
Added a new demo scene: fabricationBlocks.ttt

Added a new status bar
Reworked the coordinates and transformation dialog, as well as the method of moving object/items
Modified the way objects/items get selected when no key combination is used: objects get selected at mouse button release if the mouse didn't move. This makes it more convenient to navigate with the camera without always losing the object selection state
Added a checker background in the OpenGl-based custom UI edit mode
Added a new video compression library used by V-REP's video recorder, based on the FFmpeg library. Click here for related credits

New model: "motorbike.ttm"
V-REP V2.6.0 (January 27th 2012)
This release too underwent heavy internal changes in preparation for support of other platforms (Mac and Linux). Please inform us as soon as possible in case of unexpected behaviour with this release. Thanks!
All dialogs and user interfaces have been completely rewritten/redesigned/reorganized. They now all rely on the Qt framework
The application main loop (i.e. the default main client application) has been simplified and prepared for separate GUI thread functionality. The rendering of the scene is now handled internally. Following functions were added: simRunSimulator, simGetMainWindow, sim.loadModule, sim.unloadModule. Following functions were removed: simLaunchSimulator, simEndSimulator, simRenderScene, simHandleWindowMessages, simGetInstanceIndex, simGetVisibleInstanceIndex, simSwitchToInstance, simEmptyScene, simRegisterModuleName and simRegisterEventCallback.
Added following values: sim_message_eventcallback_guipass, sim_message_simulation_start_resume_request, sim_message_simulation_pause_request, sim_message_simulation_stop_request, sim.intparam_qt_version, sim.floatparam_rand. Following value is now also writable: sim.boolparam_console_visible
Adjusted/adapted all V-REP plugins: since this release, plugins should dynamically bind to the V-REP library. The task is simplified with two files distributed with V-REP: "simLib.h" and "simLib.cpp". This reduces compatibility problems linked to working with various compilers. Old plugins should be slightly modified: it is recommended to adjust old plugins in a similar way as was done for the "BubbleRob" plugin project, located in the "c_examples" directory of V-REP's installation directory. If you are having difficulties adjusting your plugin code, please contact us for assistance.
Fixed a bug linked to the click-and-select functionality.
Added several pre-configured simulation settings (e.g. physics engine settings or simulation time step settings). The user can conveniently modify them in the toolbar.
Added an option for turning dialogs semi-transparent when they loose focus.
Added a toolbar button to quickly visualize a scene's dynamic content (enabled during simulation only)
Added a plugin that allows to interface joysticks: simExtJoystick.dll. Like with almost all V-REP plugins, the source code can be requested if not already distributed with V-REP.
V-REP V2.5.12 (December 6th 2011)
This release too underwent heavy internal changes in preparation for support of other platforms (Mac and Linux). Please inform us as soon as possible in case of unexpected behaviour with this release. Thanks!
Improved the undo/redo functionality: undo points are now set 10-20 times faster as in previous releases, which greatly improves scene edition with large scenes.
The undo/redo functionality can now also be accessed via the ctrl-z and ctrl-y keys
Changed the splash screen and the about dialog
Since this release, it is not possible anymore to run several simulations in parallel (in different instances). This limitation greatly simplifies programming of plugins. Most old plugins should still be working, but some might need some simple adjustments. *Refer to the section below for quick instructions of modifications required.
simGetInstanceIndex, simGetVisibleInstanceIndex and simSwitchToInstance are declared deprecated and should not be used anymore.
Simplified and improved the plugin event messages
Removed following event callback messages: sim_message_object_added_or_removed, sim.message_object_selection_changed, sim.message_scene_loaded, sim_message_menu_item_selected, sim_message_eventcallback_objectscaled, sim_message_eventcallback_objectabouttobeerased, sim_message_eventcallback_objecterased and sim_message_eventcallback_objectcreated. The same functionality can be obtained with the improved sim_message_eventcallback_instancepass event callback message. This results in faster loading operation for large scenes, and simplifies programming of plugins. *Refer to the section below for quick instructions of modifications required.
Renamed rendering sensors. They are now called vision sensors, and all related API functions, API constants or references have been renamed. The old API functions and constants are kept operational for backward compatibility.
Added an option to allow for local lights (i.e. lights activated only with flagged cameras). Refer to the light dialog, the camera dialog and the vision sensor properties.
Added a new toolbar button to automatically adjust the main view to the scene, or selected objects
Added a new API function: sim.cameraFitToView (click here for a simulation that illustrates what kind of camera movement can be achieved with that function)
Added a new API function: sim.isHandle.
Added following API functions: sim.persistentDataWrite and sim.persistentDataRead.
Added a new item in the object common properties ("ignored for view-fitting")
New model: "auto fitting camera.ttm"
Removed scene: "youBotDemo.ttt"
*Most old plugins will not need any modification. It is however recommended to adjust the plugin's "simMessage" function in a similar way as was done for the "BubbleRob" plugin project, located in the "c_examples" directory of V-REP's installation directory. If you are having difficulties adjusting your plugin code, please contact us for assistance.

V-REP V2.5.7 (June 25th 2011)
Since this release, models do not required to have a dummy object as base object anymore (any object can be "model base" now). This tremendously improves the way models can be combined, with much less effort (e.g. just select a gripper, then a robot, and click [Menu bar --> Edit --> Make Last Selected Object Parent]: the resulting model is fully operational)
