I'm just beginning to use Java3d and I'd like to know how would I go about find the points of intersection of all 3D objects that have been created. So if I have 1000 objects I want to know if any of them intersect another object or multiple objects and where the points of intersection in terms of x, y and z. Most of my objects are simple: spheres, ellipsoids and cylinders and they derive from Shape3D. I use them to create more complex objects. Do I have to assign some kind of Bounds to them to make this all work or are bounds automatically done? Also I'm finding that if I have a lot (around 500) of objects on the screen, things start to slow down lots. I do have a TNT2 graphics card and I thought that should help. I tried having a single object with a lot of polygons and that was fine. Then I added extra objects but tried to keep the polygon count the same, and things start to slow down. Should this normally happen, and is there any way to speed things up.
