Motion Capture - using GPL software
It is possible to do Motion Capture () in Linux using free software with the GPL licence.
The qavimator project (http://www.qavimator.org/#screenshots) can produce .bvh files.
The .bvh-files can be used in Blender to produce nice animations as described here http://pagesperso-orange.fr/jb.perin...Animation.html
and here http://centralsource.com/blender/bvh/files.htm
with a nice video here http://www.youtube.com/watch?v=_mLseb477wU
Well, I have not tried it myself, but it does look feasible.
Anyone with experience doing this or any other tips for animators?
