PyBullet: Implement a few more APIs of PhysX backend, resetJointState and setJointMotorControl2
allow useMaximalCoordinate=True for PhysX loadURDF (only for single rigid bodies, articulations require reduced coordinates at the moment)
Add inverse dynamics / mass matrix code from DeepMimic, thanks to Xue Bin (Jason) Peng
Add example how to use stable PD control for humanoid with spherical joints (see humanoidMotionCapture.py)
Fix related to TinyRenderer object transforms not updating when using collision filtering
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
Made necessary changes to ```humanoid_deep_mimic_env.py``` file, setting ```initial_frame``` to new position after simulation steps and setting ```SimTime``` using this new initial frame time
Using calculateInverseDynamics with zero target acceleration allows to compute the non-linear dynamics forces (coriolis/gyroscopic) and/or gravity force.
implement deepmimic reward function (only joint angles/velocities for now)
fix an out-of-date comment, related to contactPoint.m_lateralFrictionInitialized in btSequentialImpulseConstraintSolver.cpp
Add preparation for DeepMimic humanoid environment, replicating parts of https://github.com/xbpeng/DeepMimic
Loading humanoid.urdf and applying motion action: examples/pybullet/gym/pybullet_envs/mimic/humanoid.py
Loading MotionCapture data: examples/pybullet/gym/pybullet_envs/mimic/motion_capture_data.py
Little test: examples/pybullet/gym/pybullet_envs/mimic/humanoid_test.py
Expose this btMultiBodySphericalJointMotor through PyBullet.setJointMotorControlMultiDof
Expose PyBullet.getQuaternionSlerp
Improve PyBullet.setJointMotorControlMultiDof
Improve humanoidMotionCapture.py with slerp and using setJointMotorControlMultiDof
Expose btMultiBody::spatialTransform
Fix btMultiBody::setupPlanar from DeepMimic codebase
Add support for multidof joints in btMultiBody::compTreeLinkVelocities, thanks to DeepMimic codebase @xbpeng
