Hello > http://www.j3d.org/tutorials/raw_j3d/chapter6/collisions.html > http://www.j3d.org/tutorials/collision/index.html
thx. (Sorry about the wrong reply-address) I have read both... and still have a question, so: I have 4 "main"-BranchGroups, each containing one kind of "object" (around 2000 shapes per branchgroup). The shapes are all around the universe and mixed wildly. But there are many clusters of 4 shapes, one form each branchgroup/kind touching each other. I need behavior what is triggered if 2 of the same kind hit eachother. So a shape from BranchGroup 1 + a shape from branchgroup 2 => no collision, no behavior triggered. Two from group X => collision, behavior triggered. The way i understand the WakeuponCollision-System you can only specify the arming node, not what you expect to hit it. The shapes in clusters get triggered every frame. 3500 behaviors triggered per frame is to much for this PC. So i think the easy way out is the picking-system, right ? But that makes one pick per shape per frame. I have not implemented this yet but i think it's way too slow. cu =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
