[tuhopuu-devel] questions about ODE support and Plug-Ins

[Kester Maddock]

Hi Joshka,

ODE was implemented into blender for it's collision detection & 
response.  I did some of the later hacking on it.

It's usefulness to you is entirely dependant on what you are using ODE 
for.  Blender was only using it for collision detection (triggering 
logic) and collision response (physics.)  None of the more advanced ODE 
stuff (hinges, motors) was implemented.

It is possible to write a python plug in to export geometry data, in any 
format you want.

If you want to check it out, checkout tuhopuu and build the 'kesterji' 
engine.
