[Bf-committers] Collada status

[Ton Roosendaal]

Hi,

Thanks everyone for all the feedback!
I think it would make a great meeting topic next sunday.

Hopefully the meeting can come up with recommendations/decisions or  
plans for:

- volunteer(s) to be official module owner/maintainer
- evaluate if we stick to existing python code, need new python api, or  
switch to C/C++ ?
- planning or roadmap for work

I cannot be there sunday... so here's my take:

Short term:
Get the exisiting script back to work a.s.a.p. Maybe it only needs  
minor improvements. Focus on practical specs; get good quality  
im/export of 3D models, texture coordinates, scene layouts. Only after  
that go for more advanced specs (character animation data, modifiers,  
shaders, physics, logic, ...).

Mid term:
Evaluate all the alternatives. A quick glance on collada-dom is that it  
has a nice concept (C++ database representation of a collada file).
