3bf27cf8f2 implement rudimentary contact callback. Does PhysX have a way to report ALL contact points, every frame, so we can update contact forces etc, and report all contacts? 2019-02-20 21:38:37 -08:00

bdf9b10246 more work on pybullet_envs.deep_mimic.
allow btMultiBody to not wakeup (for some RL experiments)
move deep_mimic motion files to data/motions folder, so we can use the args files unmodified.

85ee4c2934 allow batch creation of objects through PyBullet.createMultiBody, see createMultiBodyBatch.py example.
expose minGraphicsUpdateTimeMs through PyBullet.connect(p.GUI, options="minGraphicsUpdateTimeMs=32000"), by default OpenGL rendering runs at 4000microseconds intervals.
allow a maximum of 128k objects
fix meshScale for PyBullet.createCollisionShape for custom mesh
expose Pybullet.setPhysicsEngineParameter(minimumSolverIslandSize=...), larger minimum batches group solver constraints together in the same island, to reduce calling overhead (even if they are not related)

bf9efffa4b Increase mesh allocation for vertices/indices in PyBullet.createCollisionShape
See createMesh.py for an example.

The data has to fit in shared memory, hence the limit on Mac is lower than Windows and Linux:

#ifdef __APPLE__
#define B3_MAX_NUM_VERTICES 8192
#define B3_MAX_NUM_INDICES 32768
#else
#define B3_MAX_NUM_VERTICES 131072
#define B3_MAX_NUM_INDICES 524288
#endif

a44df2b0a6 PyBullet: allow to pass vertices (for convex) and vertices+indices (for concave) to createCollisionShape
See createObstacleCourse.py for an example use. At the moment a limit of 1024 vertices and 1024 indices.
Will be lifted once we implement the streaming version (soon).

9553892770 PyBullet / BulletRobotics:
Implement collisionFilterPlugin, use setCollisionFilterPair to enable or disable collision detection between specific pairs of objects.
Also, expose setCollisionFilterGroupMask as PyBullet API and in urdf using the tag <collision group="1" mask="2"/>.
See examples/pybullet/examples/collisionFilter.py for an example.
PyBullet default: Lower the warmstarting factor, for maximal coordinates rigid bodies for more stable simulation.
Add btCollisionWorld::refreshBroadphaseProxy to easier recreate the broadphase proxy without adding/removing objects to the world.
