192d27743a enable pybullet.calculateInverseDynamics for floating bodies
Using calculateInverseDynamics with zero target acceleration allows to compute the non-linear dynamics forces (coriolis/gyroscopic) and/or gravity force.

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).

ed49edc1af PyBullet change API (since it was broken): pybullet_changeVisualShape with textureUniqueId ==-1 will clear the texture
b3InitUpdateVisualShape doesn't take textureUniqueId by default. new API b3UpdateVisualShapeTexture to change texture (-1 will clear texture)
PyBullet/BulletRobotics: allow to reset the textureUniqueId to -1, to clear a texture
PyBullet/BulletRobotics: save all texture handles

dba239fe8d First pass of load files through an interface (to allow loading from memory, zip file etc). So instead of posix fopen/fread, using CommonFileIOInterface.
A fileIO plugin can override custom file IO operations. As a small test, load files from a zipfile in memory.
Default fileIO implementation is in examples/Utils/b3BulletDefaultFileIO.h
Affects URDF, SDF, MJCF, Wavefront OBJ, STL, DAE, images.

ab8f16961e Code-style consistency improvement:
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh

b73b05e9fb add getClosestPoints.py example.
allow to perform a getClosestPoints query with a collisionShape and world transform (position, orientation) that isn't part of the world.

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.

9698c3d600 PyBullet setup.py: only enable BT_USE_EGL on Linux, but allow to run the eglPlugin on Windows and Mac as well (using their default opengl window).
postpone the 'loadPlugin' for static eglPlugin, so that the init and exit happen in the same thread.
When you don't call unloadPlugin, the program may crash when exiting in SHARED_MEMORY_SERVER mode.

0efc67841d allow pybullet to connect to GRPC server. (need to use flag --enable_grpc in premake build system)
add grpcPlugin, it can work in GUI, SHARED_MEMORY_SERVER, DIRECT and other modes.
example script to start server from pybullet:
import pybullet as p
p.connect(p.GUI)
#if statically linked plugin
id = p.loadPlugin("grpcPlugin")
#dynamics loading the plugin
#id = p.loadPlugin("E:/develop/bullet3/bin/pybullet_grpcPlugin_vs2010_x64_debug.dll", postFix="_grpcPlugin")

#start the GRPC server at hostname, port
if (id>=0):
	p.executePluginCommand(id, "localhost:1234")

Only in DIRECT mode, since there is no 'ping' you need to call to handle RCPs:
numRPC = 10
while (1):
	p.executePluginCommand(id, intArgs=[numRPC])
