Morning

before anyone else does it: http://lmgtfy.com/?q=java+3d+collision

I have spent to past few months searching the internet for a way to get 3D collision working within my game engine to no avail. I have tried to write my own, JBullet, converting c/c++ library (Bullet, coldet, etc.) and hitting my head against a wall until something happens.
What I have been looking for is a system that will be able to identify if two OBJ files intersect and resolve to it. I have run out ideas of what to do next, any ideas, suggestion or a library that I may be able to use?

thanks is advance,
siD

Kasper Fauerby’s tutorial on his site http://www.peroxide.dk/ is still one of the best ones IMHO. If implemented correctly, it will give you really good collision detection and response.

Are the objects potentially non-convex?
