[Bf-committers] Re: Bullet physics plans/status/update

[erwin at erwincoumans.com]

I'm involved in COLLADA physics, which is a standardization of the data 
specification for rigidbody dynamics. Such data specification is related to 
an API but not enough. There is a C++ abstraction layer called OPAL, but I 
want a C API. Open Dynamics Engine provides a C API, but it is too specific 
for that engine. I'll probably re-use some of the ideas of the ODE API and 
SOLID collision detection API, but add some of the features necessary to 
cover Bullet (and Havok and Ageia). 

Thanks,
Erwin
