Real-time implementation of inverse kinematics (IK). Each ‘IK solver thread’ reads and solves a different frame, which is read from the ’Raw marker trajectories’ buffer. Results are then stored in the ‘Unsorted joint angles’ buffer. The ‘Sequencer thread’ puts in the correct temporal order the ‘Unsorted joint angles’ using the time stamps stored in the ‘Times stamps’ buffer.
