about

nx_pose_retarget_gate.nx -- prove RETARGET (roadmap R3) inverts the FK: known joint ANGLES -> FK -> joint POSITIONS -> retarget -> (T1) positions REPRODUCED + (T2) angles RECOVERED + (T3) a 2-frame track gives distinct poses. This is "a pose track drives our rig" -- the video->pose->MOTION heart. expect_exit:0 ORIGINAL
