Yeah, me :)
Can someone send me a snippet of code to make the collision detection behaviors work?
To make it work, you need to make sure that you either clock it yourself with your per-frame behaviours or that you use the built in one that is available through the getTimerBehaviour() method. This behaviour you then add to your scene graph in the normal way.
Also, can these be used for i.e. 2 objects colliding, and not the viewer/objects?
No. This is purely object to object collision. I have a Java port of Kelvin's HS-Jump variant of Q-Collide that I'm working on. It's mostly done, but I haven't really completed it yet, and therefore not in CVS. There's a couple of major pieces still missing. If you would like to help out with the implementation work, I'd be more than happy to commit the code to CVS and let you have a play. Right now, my work is focussed on getting the port of the NYU/Bierman Subdivide 2.0 library completed.
Several questions: what is HS-Jump variant of Q-Collide ? What are the differences, which is the best ? Isn't the Java3DFly 2.0 collision ok by itself ? When will you put the code on J3d.org ? on a separate track, what is NYU/Bierman Subdivide 2.0 ?
By the way, I have seen there was a Java revolve class for NURBS system for VRML you produced sometime ago, is this feature also supported by the NURBS package on J3D.org ?
Thanks.
P.S. Sorry for all those annoying questions.
