======IOR Gait Joint Angle======

=====Overview=====

This tutorial is a continuation of the [[visual3d:tutorials:modeling:ior_gait_full_body_model|IOR Gait Full Body Tutorial]]. This tutorial goes through computing different joint angles specific to the IOR Gait model.

==== Joint Angles ====
The Tho_Pel and Tho_Lab angles are described here, while the lower extremity joint angles were created based on the 
segment coordinate systems described here
