hi, this seems quite a exciting and yet a challenging project.
I would like to work on it.
It's basically matrix transformations in 3d space, I think Panda3d framework will be a good candidate for this task, it has necessary tools and a solid api.
maybe can import raw data and output bvh format or xml file that is readable by other software.
I would like to know more details.
feel free to contact me anytime.
Obaid.
