Thanks for your answer !!! In fact, what i'd like to do is :
1. take a Plane and explode it into triangles (i made it !!!) 2. distribute all these triangles on a sphere (i made it too !!! ) 3. I d'like to position them on the sphere like this : http://forum.papervision3d.org/viewtopic.php?f=20&p=4989 The problem I have now is that i can't find a way to get the good rotation angle to do that. I think i have to use Quaternion but i don't understand anything about Quaternion. Thanks for your help !!!
