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
Remove roof from kitchens/1.sdf, otherwise shadows and shinyness won't work (light is outside the room, bouncing against roof-top)
Make kuka_iiwa/model.urdf more smooth, use .obj for per-vertex normals (using Blender, import STL, export OBJ, enable triangles, normals and Z-UP, Y forward)
fix in b3HashString
remove many unused dependencies from kuka_grasp_block_playback.py (time,math, datetime ,numpy,pylab ,sys, os, fnmatch,argparse were not used!)
move block_grasp_log.bin from Bullet3/data to Bullet3/examples/pybullet/examples/data folder.
PhysicsServerCommandProcessor, derive from CommandProcessorInterface to prepare for different back-end implementation
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
disable Grasp Soft Body/SoftBody coupling demo unless USE_SOFT_BODY_MULTI_BODY_DYNAMICS_WORLD is defined, fixed related hang in experimental 'loadBunny' command
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)
