erwincoumans 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.

fixes in eglRendererPlugin
 2018-09-10 07:51:39 -07:00
erwincoumans 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.

erwincoumans adb5c049c7 Thanks to @dchichkov for some of the fixes in the eglRendererPlugin! 
Rename tinyRenderer -> eglRenderer in the eglRendererPlugin.
Allow to run the eglRendererPlugin to run on Windows (not in EGL mode but Win32OpenGLWindow mode)

Here is a script I tested on Windows:

erwincoumans 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])

erwincoumans ee9fca8c29 GJK fix for https://github.com/bulletphysics/bullet3/issues/1703 
In a nutshell, we added a more reliable check, based on if the origin is in the GJK simplex, to determine if we are really intersecting and need to run EPA.
See also "Real-time Collision Detection with Implicit Objects" by Leif Olvang
Todo: integrate the simplex penetration check directly inside the Bullet btVoronoiSimplexSolver
and remove this temporary code from libCCD
Note, for large differences in shapes, use double precision build!
