pybullet.changeVisualShape(obUid,linkIndex,specularColor=[R,G,B]) and Bullet C-API b3UpdateVisualShapeSpecularColor
Bug fixes in b3ResourcePath::findResourcePath resolution.
add stadium.sdf and roboschool/models_outdoor/stadium assets https://github.com/openai/roboschool/tree/master/roboschool/models_outdoor/stadium
minor fixes to obj2sdf
Bullet C-API b3ChangeDynamicsInfoSetSpinningFriction/RollingFriction/Resitution
b3PhysicsParamSetRestitutionVelocityThreshold, / pybullet.setPhysicsEngineParameter restitutionVelocityThreshold:
if the velocity is below this threshhold, the restitution is zero (this prevents energy buildup at near-resting state)
pybullet restitution.py example.
example:
kuka = p.loadURDF("kuka_iiwa/model.urdf")
p.getNumJoints(kuka)
pybullet.addUserDebugLine([0,0,0],[0,0,0.1],[0,0,1],trackObjectUniqueId=2,trackLinkIndex=6)
pybullet.addUserDebugText("tip", [0,0,0.1],textColorRGB=[1,0,0],trackObjectUniqueId=2,trackLinkIndex=6)
Also allow to render text using a given orientation (instead of pointing to the camera), example:
pybullet.addUserDebugText("tip", [0,0,0.1],textColorRGB=[1,0,0],textOrientation=[0,0,0,1], trackObjectUniqueId=2,trackLinkIndex=6)
Add drawTexturedTriangleMesh, for drawing 3d text.
Expose readSingleInstanceTransformToCPU, to extract position/orientation from graphics index.
updateTexture: allow to not flip texels around up axis
pybullet.setPhysicsEngineParameter(enableFileCaching=0)
Allow VR camera tracking only using position tracking, no orientation tracking (use
pybullet.setVRCamera([posX,posY,posZ],trackObjectFlag=0 or pybullet.VR_CAMERA_TRACK_OBJECT_ORIENTATION)
Expose COV_ENABLE_VR_RENDER_CONTROLLERS, to enable/disable rendering of controllers (and some frames) in VR
Expose COV_ENABLE_RENDERING to enable/disable rendering.
Fix some multi-threading issues (potential crashes), related to debug drawing/rendering in one thread, while changing the dynamics world/removing/resetSimulation in a different thread.
Expose this ChromeTraceUtil logging to C-API: start/statelogging and submitProfileTiming
pybullet.submitProfileTiming, and STATE_LOGGING_PROFILE_TIMINGS used in startStateLogging
added example for Python profileTiming.py and C++ b3RobotSimulatorClientAPI::submitProfileTiming
First run the App_PhysicsServer_SharedMemory_VR_vs2010.exe to run the VR server,
then run App_VRGloveHandSimulator. You likely need to tune the minV/maxV for each finger (check values using Arduino IDE Serial Monitor)
don't enable <CTRL> for hotkeys yet
add some more profile markers
log objectId and linkIndex as signed int ('i') and not unsigned int 'I'
fix issue in startStateLogging: number of parameters was wrong
pybullet setup.py / pip support for Windows, Linux and Mac! just run 'pip install pybullet' and wait until all compiled (like numpy, it is mainly source, except for a few wheels Mac 2.7 and Win32 3.5). Expose URDF_USE_SELF_COLLISION flag.
suppress lack of 'site' support message in MJCF importer
suppress lack of 'plane' visual support in urdf/sdf import
getBodyName default to "" to avoid breaking cloudsim
expose bodyName when requesting body info (sdf/mjcf import)
pass optional "options" string to pybullet.connect method. this can be used for --opengl2 flag in GUI mode (or other flags)
For example: URDF_USE_INERTIA_FROM_FILE flag. By default, URDF2Bullet will re-compute the inertia tensor based on mass and volume, because most URDF files have bogus Inertia values.
Add several MSVC optimization flags to cmake.
Bump up VERSION because serialization format changed
Expose btScalar& jointMaxForce, btScalar& jointMaxVelocity to 'getJointInfo2' API, add backwards compatibility to examples\Importers\ImportURDFDemo\URDFImporterInterface::getJointInfo.
pybullet: expose 4 more fields to getJointInfo: jointLowerLimit/jointUpperLimit/jointMaxForce/jointMaxVelocity
fix performance issue in CMD_ACTUAL_STATE_UPDATE_COMPLETED
implement friction anchors, position friction correction, disabled by default. Use colObj->setCollisionFlag(flag | CF_HAS_FRICTION_ANCHOR); See test/RobotClientAPI/SlopeFrictionMain.cpp. In URDF or SDF, add <friction_anchor/> in <contact> section of <link> to enable.
PhysicsServer: properly restore old activation state after releasing picked object
btMultiBodyConstraintSolver: disable flip/flop of contact/friction constraint solving by default (it breaks some internal flaky unit tests)
add minitaur quadruped playback of minitaur log files (real robot and simulated create the same log files)
add improved minitaur.urdf file, see https://youtu.be/lv7lybtOzeo for a preview.
add missing 1.sdf for Bullet/data/kitchens/1.sdf
add support for getting keyboard events (pybullet.getKeyboardEvents and b3RobotSimulatorClientAPI::getKeyboardEvents)
tune gripper grasp example with tefal pan, 800Newton force.
URDF importer: if using single transform 1 child shape, don't use compound shape.
if renderGUI is false, don't intercept mouse clicks
add manyspheres.py example (performance is pretty bad, will look into it)
[pybullet] expose contactBreakingThreshold
update to latest OpenVR 1.05 SDK from https://github.com/ValveSoftware/openvr
add keyboard support to tune default camera VR position
VR revert to double 'distorted' views on Desktop, since the single view isn't showing full scene
[pybullet] updated pybullet_quickstartguide.pdf
Fail clearly (assert, return BT_INFINITY) if link index is out of range for btMultiBody methods localPosToWorld,worldPosToLocal,localDirToWorld,worldDirToLocal.
pybullet getConstraintInfo
Fix warnings due to Mac OSX 10.12 upgrade (with backward compatibility)
https://www.youtube.com/watch?v=VMJyZtHQL50
added b3InitSyncBodyInfoCommand, to retrieve body info, when connecting to a server with existing bodies
pybullet will call this b3InitSyncBodyInfoCommand automatically after connecting
Avoid overriding the py.setVRCameraState setting in VR
fixed some more warnings
added alignment macros to some classes
btPersistentManifold from 128 to 16 bytes aligned
prepare command to select collision filter mode (SIM_PARAM_UPDATE_COLLISION_FILTER_MODE)
Windows shared memory: allow to use custom key.
Improve GUI performance on Windows, submit letters in text as a batch (fewer draw-calls)
quadruped.py: first try to connect to SHARED_MEMORY, if it fails (<0) use GUI
increase Chrome about://tracing json export capacity (press 'p' in Example Browser)
UDP physics server: add --port and --sharedMemoryKey command-line arguments
PhysicsServerExample: add --sharedMemoryKey command-line option (for VR example too)
ExampleBrowser: sleep a few milliseconds if rendering is too fast, use --minUpdateTimeMicroSecs=0 to disable
vrevent.py: add a Tiltbrush-style drawing example using pybullet
Expose getVREvents to pybullet / shared memory API, access to any VR controller state & state changes.
Improve performance of user debug lines (pybullet/shared memory API) by batching lines with same color/width
expose rayTest to pybullet/shared memory API (single ray for now)
add pybullet getMatrixFromQuaterion
Make btQuickprof thread safe
Add option in btQuickprof to override custom timing profile (btSetCustomEnterProfileZoneFunc, btSetCustomLeaveProfileZoneFunc)
remove b3Printf in a user/physics thread (those added added, while drawing the GUI running in the main thread)
(for example solverInfo().m_leastSquaresResidualThreshold = 1e-7 and use large m_numSolverIterations
disable sphere-sphere contact cache, it is buggy (some contact point stay in the cache, when sphere penetrates more than total margins)
tweak some gpu demo settings
allow 'useMaximalCoordinates' and 'useFixedBase' in pybullet.loadURDF.
enable split impulse for btRigidBody, even in btMultiBodyDynamicsWorld.
allow initialization of velocity and apply force for btRigidBody in pybullet/shared memory API.
process contact parameters in URDF also for btRigidBody (friction, restitution etc)
add pybullet.setPhysicsEngineParameter with numSolverIterations, useSplitImpulse etc.
add option to perform filtering of 'getClosestPoints' using linkA/linkB.
don't use 'realtimesimulation' as default
add/remove debug items within same thread
pybullet, report contact points and normal as [x,y,z] triplet/vector, not 3 scalars
separate 'getClosestPointsAlgorithm': box-box doesn't report closest points with positive distance, and the query shouldn't impact regular 'closesst points'
always pass in width, hight and viewMatrix, projectionMatrix, optionally lightDir
added helper methods computeViewMatrix, computeViewMatrixFromYawPitchRoll, computeProjectionMatrix, computeProjectionMatrixFOV
see Bullet/examples/pybullet/testrender.py + testrender_np.py for example use
add missing base_link.stl for husky.urdf
update to OpenVR sdk 1.03 from https://github.com/ValveSoftware/openvr
add camPosX/Y/Z and camRotZ to adjust relative camera/world transform for VR (so you can align virtual table with real table etc)
tweak quadruped.py to move a bit
add mouse picking to physics server
