e98fca1e5e implement pybullet.getContactPointData(), two optional object unique ids as filter
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;

85fd7f560c add first draft of contact point query in shared memory API
b3SharedMemoryCommandHandle b3InitRequestContactPointInformation(b3PhysicsClientHandle physClient);
void b3SetContactFilterBodyA(b3SharedMemoryCommandHandle commandHandle, int bodyUniqueIdA);
void b3SetContactFilterBodyB(b3SharedMemoryCommandHandle commandHandle, int bodyUniqueIdB);
void b3GetContactPointInformation(b3PhysicsClientHandle physClient, struct b3ContactInformation* contactPointData);
Implemented for PhysicsClientSharedMemory, not for PhysicsDirect yet.
Add btCollisionObject::setUserIndex2

5b0253ed47 Remove undesired assert, it makes pybullet mistakes fail in c++
Shared memory api/pybullet: by default, set joint motors in position PD mode with target 0, to maintain 0 joint angle.
pybullet: allow setJointControlMode(body, link, POSITION_CONTROL,targetPos etc.

3c30e2f821 add segmentation mask rendering to TinyRenderer and shared memory API
similar to the zbuffer, but storing the object index (int) instead of float depth

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.

60d2b99151 Physics runs in a separate thread from rendering in PhysicsServerExample (preliminary)
Improve rendering performance. OpenVR experience is smooth now.
commit needs a bit more testing before pushing in main repo.

6523df336e Fix pybullet Windows build errors: C99 requires variables to be defined at the start of the function.
Improve CMake Windows support to build PyBullet (BUILD_PYBULLET)
Implement b3LoadSdfCommandInit in shared memory API
Implement pybullet SDF loading binding, in loadSDF API
TODO for SDF support is provide way to query object/link/joint information.

14aa666c6f preparation to receive camera image data from physics server
increase shadowmap world size default to 50 units (meter), 10 units (meter) was too small for most examples.

2fc0358750 Expose a better API to allow any render engine to be used for the physics simulation when loading URDF/SDF files.
See bullet3/examples/Importers/ImportURDFDemo/DefaultVisualShapeConverter.h
Give the kuka_iiwa/model.urdf some blue color, not just orange, to mimick the original a bit better
Preparation for the CMD_CAMERA_IMAGE_COMPLETED command, to expose a virtual camera to the robotics API

efbb1edecc Allow InProcessExampleBrowser to use a malloc allocated memory block, instead of system shared memory.
Make shared memory client/server a bit more robust, in case the server is terminated early.

03bf78ef49 add physics server loopback (both client and server in the same process, using shared memory)
add physics server direct (client and server in the same process, directly processing commands without shared memory transport mechanism)

a0e507280c Implement CMD_INIT_POSE to set base position, base orientation and joint position (angle).
See PhysicsClientExample for example use of CMD_INIT_POSE.
Change: CMD_INIT_POSE uses m_initPoseArgs and not m_sendDesiredStateCommandArgument

5e4badc099 make PhysicsClient an interface class, and move shared memory implementation
of physics client into PhysicsClientSharedMemory class/file.
This will allow implementation of UDP and other transport protocols to a physics server.
