Re: [Openvrml-develop] Simple Object to Object Collision Detection

[Sylvain C. <syl...@to...>]

I donr know if you know about this one but seem quite pertinent at this stage
I think:
 SOLID - Software Library for Interference Detection
LPGL, designed with vrml in mind, use stl, can be used with or without qhull.
Maybe could be retrofitted into openvrml?
You'll find more links in this pages to others collision library too.
