I try to explain more clearly my problem
does someone Know how to test if two shape are in collision
to make a method like this
public static boolean intersect(Shape3D s1, Shape3D s2)
because it seem to be possible only with bounds and i need a good test to know if to object are intersecting
just like the wake stuff when he use GEOMETRY
cyril
thank
For j3d 1.2.1 at any rate, you have to use either Bounds objects or your own code. Also, Shape3D has getBounds and getCollisionBounds methods but I found the former just returns bounding boxes based on the geometry and the latter returns null unless something is set with setCollisionBounds. For what I wanted to do, I used a native C/C++ method I got that does triangle-to-triangle interference detection, then used TriangleArray geometry objects just to display stuff in the j3d scene. I don't think Sun plans and/or has yet decided on a standard scheme for doing interference+collision detection and j3d leaves it up to you for now...
