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;

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.

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

9cc2b1ec12 Physics SharedMemory:
Add flags BOX_SHAPE_HAS_MASS and  BOX_SHAPE_HAS_COLLISION_SHAPE_TYPE to CMD_CREATE_RIGID_BODY
(which maps to CMD_CREATE_BOX_COLLISION_SHAPE for backward compatibility for now)

e05825f639 improvements to the shared memory physics API:
support picking in C API etc.
2015-09-24 22:42:22 -07:00
=
003a42478b another step closer to useable shared memory C API
(force/torque sensor needs new API)
in a nutshell, users of shared memory physics API should not
directly poke into shared memory, not fill 'SharedMemorCommand'
nor read SharedMemoryStatus directly. The C-API declares 'handles' for those,
to avoid it from happening.
