Hi Robert, Sorry my question was not complete. By envelope I mean convex hull. BB and BS are too simple to approximate any 3D model to my mind. The "convex" is not necessary, just a hull could be fine. I'll be interested in every code/idea/suggestion about that. Thanks a lot. Regards, V

HI Vincent, What do you mean by 3D envelope, it's rather an open ended all by itself. Convex hull? Bounding box? Bounding sphere? A pre-paid A4 envelope perfect for sending large pictures through the post? Robert. On Thu, Sep 2, 2010 at 3:12 PM, Vincent Bourdier wrote: >  Hi all, > > I am c

Hi all, I am currently looking for a way to compute envelopes from 3D datas (Geometry, Groups, etc...) I saw that external lib could do it, but first of all I ask to all of you if someone did something for OSG that could help me. That would help me a lot in my work. Thanks for your help.
