Hi Author, A question: what is the meaning of trans_matrix here? Why it is used? Thanks

I guess it's a coordinate transformation. Maybe the data obtained from AMASS is under coordinate system like Blender(the +z axes is pointing upward), pose_seq_np_n = np.dot(pose_seq_np, trans_matrix) is changing the pose sequences to coordinate system like OpenGL(+y axes is pointing upward, +z is pointing out of the screen )
