use btAssert to detect 0 determinant in btMatrix3x3 inverse
Remove obsolete comment in PosixSharedMemory, the Windows shared memory implementation was done over a year ago
Add physics time scale in VR mode
Fix compound collision margin in physics server
Enable visuals for rigid body (non-multi-body) URDF/SDF loading in physics server.
add rolling/spinning friction to cube, remove it from plane/samurai.urdf
URDF2Bullet: support joint limits for revolute and prismatic, only if defined (if upper < lower, disable limit)
add some profiling markers to improve performance
rolling friction -> only along the normal, until we have separate rolling friction coefficients on normal and non-normal directions
Don't teleport with grasping controller (VR)
Tune VR grasping a bit.
option is disabled by default. When using cmake, use
cmake -DBUILD_PYBULLET=ON -DBUILD_PYBULLET_NUMPY=ON
then both testrender.py and testrender_np.py will work
without numpy only testrender.py works.
The numpy.reshape is likely a no-op when using numpy array,
so we could remove testrender_np.py...
See https://github.com/bulletphysics/bullet3/pull/774
URDF/SDF: add a flag to force concave mesh collisiofor static objects. <collision concave="yes" name="pod_collision">
VR: support teleporting using buttong, allow multiple controllers to be used, fast wireframe rendering,
Turn off warnings about deprecated C routine in btScalar.h/b3Scalar.h
Add a dummy return to stop a warning
Expose defaultContactERP in shared memory api/pybullet.
First start to expose IK in shared memory api/pybullet (not working yet)
returns a pylist of contact points. Each point has the following data:
0 int m_contactFlags;//unused for now
1 int m_bodyUniqueIdA;
2 int m_bodyUniqueIdB;
3 int m_linkIndexA;
4 int m_linkIndexB;
5-6-7 double m_positionOnAInWS[3];//contact point location on object A, in world space coordinates
8-9-10 double m_positionOnBInWS[3];//contact point location on object A, in world space coordinates
11-12-13 double m_contactNormalOnBInWS[3];//the separating contact normal, pointing from object B towards object A
14 double m_contactDistance;//negative number is penetration, positive is distance.
15 double m_normalForce;
