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.
