552cb5852a PyBullet: add signed distance field support, with example/signedDistanceField.py 
See also data\toys\concave_box.urdf and data\toys\concave_box.cdf

data\toys\concave_box.cdf was generated from concave_box.obj using
//GenerateSDF.exe -r "32 32 32" -d "-1.6 -1.6 -.6 1.6 1.6 .6" concave_box.obj
//SDF is based on code from DiscreGrid, https://github.com/InteractiveComputerGraphics/Discregrid

01f58f8f02 PyBullet: soft bodies are rendered, so we don't need to also render wireframes in regular mode. 
Use glBufferSubData instead of glMapBuffer/glUnmapBuffer, much faster soft body vertex sync.
Don't use a separate btSoftBodyWorldInfo, use the existing one in btSoftMultiBodyDynamicsWorld.

ddf304ca78 PyBullet: expose internal edge utility, to adjust edge normals to prevent object penetrating along triangle edges of concave triangle meshes 
(due to local convex-triangle collisions causing opposite contact normals, use the pre-computed edge normal)
PyBullet: expose experimental continuous collision detection for maximal coordinate rigid bodies, to prevent tunneling.

79051b7611 allow to use colors from MJCF file as option (default to random Google colors), use p.loadMJCF(filename, flags=p.URDF_MJCF_COLORS_FROM_FILE

79d78a325a Start of a urdfEditor.py, limited support to extract a URDF from a PyBullet body. 
Use btCylinderShapeZ for URDF cylinder, instead of converting it to a btConvexHullShape.

Extend PyBullet.getDynamicsInfo / b3GetDynamicsInfo, remove flag (don't rely on API returning a fixed number of elements in a list!)
Extend PyBullet.getJointInfo: add parentIndex

0326fa93a8 made some progress in saving and restoring the state during the simulation, with identical results. 
Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.
