How to convert 3D skeltal data to Euler representation like Kinect?

Question

The CMU motion capture data stored the skeleton of each frame as Euler angles. It is easy to convert the Euler angles to 3D points by using Mocap Toolbox. But I wondered how to do the inverse operation? It seems like the Kinect has the same operation: firstly obtained the 3D coordinates of human from the depth camera; secondly, stored these coordinates as Euler angles.

Answer 1

I have found that Motion Builder can convert the C3D dataset into BVH formats. It is exactly what I want. I am going to exploit the programming methods to achieve that.
