9ee1c4ec24 regular OR wireframe rendering, not both
add option to perform filtering of 'getClosestPoints' using linkA/linkB.
don't use 'realtimesimulation' as default
add/remove debug items within same thread
pybullet, report contact points and normal as [x,y,z] triplet/vector, not 3 scalars
separate 'getClosestPointsAlgorithm': box-box doesn't report closest points with positive distance, and the query shouldn't impact regular 'closesst points'

c2ca88bf44 added b3PhysicsParamSetInternalSimFlags command, and pybullet setInternalSimFlags API.
//Use at own risk: magic things may or my not happen when calling this API.

This allows to enable/disable robot assets (samurai world, gripper, KUKA robot etc) in Physics Server (and App_PhysicsServerVR etc)
1 = create robot assets
2 = create experimental box-vr-gui

Add optional command-line parameter for App_PhysicsServerVR, --norobotassets, to start with an empty world, no assets in VR (no gripper, no kuka)

a9b1544a9f Add premake support to build pybullet, Windows and Linux tested, will enable Mac in next commit.
Expose inverse dynamics to Bullet shared memory API, through b3CalculateInverseDynamicsCommandInit and
b3GetStatusInverseDynamicsJointForces command/status. See PhysicsClientExeample or pybullet for usage.
Add option for Windows and Linux to set python_lib_dir and python_include_dir for premake and --enable_pybullet option
Expose inverse dynamics to pybullet: [force] = p.calculateInverseDynamics(objectIndex,[q],[qdot],[acc])
Thanks to Jeff Bingham for the suggestion.

c28cd03fbd OpenVR controller can pick/drag objects. Instructions, Windows only:
Compile using premake+visual studio, and compile App_SharedMemoryPhysics_VR
Compile pybullet using cmake using cmake -DBUILD_PYBULLET=OFF -DCMAKE_BUILD_TYPE=Release ..
Create a symbolic link from c:\python\dlls\pybullet.pyd to C:\develop\bullet3\cmp\lib\Release\pybullet.dll
App_SharedMemoryPhysics_VR
Run Python. Here are some Python lines to get going:
import pybullet as p
p.connect(p.SHARED_MEMORY)
p.loadURDF("cube.urdf")
p.setGravity(0,0,-10)
p.setRealTimeSimulation(1)

Allow real-time simulation in physics server, add pybullet command setRealTimeSimulation to control it
Mesh decimation (reduce number of triangles/vertices) using a Blender modifier for Kuka IIWA and Husky
Disabled the 'glFlush' commands in GLInstancingRenderer.
Add VR controller methods to examples\CommonInterfaces\CommonExampleInterface.h
Use the ANSI version in Windows file/string operations instead of unicode, hope this doesn't break builds.
