[Bf-committers] Re: motion capture blender

[Matthias for Blender]

Well, it's just an offer. I am reworking the code for my own purposes,  
and I am very aware that only few people have mocap systems in their  
basement.

I decided to put this code up specifically for you Blender guys,  
because Blender is a fantastic tool that I have used a little and plan  
on using a bit more, and if something so cool is free, I like to give  
back.

A mocap driver is a good addition for Blender's game engine and  
real-time capabilities, and there may probably 20 o 50 studios out  
there that may make good use out of that. Maybe a few of those studios  
are willing to give a donation, which then would help the whole Blender  
community.

Anyway, I hope the code helps somewhat. I'll be happy to officially  
LGPL it, with the limitation to Blender and directly derived work  
though (which would not harm any other part of Blender, the GPL or  
LGPL).
