I don't believe you can. Maybe soon since Java3D is open source now. However, you would be better off, imo, to use either Xith3D or jME.
Xith3D is very very similar to Java3D and it uses either lwjgl or jogl which are both opengl wrappers for java and have MAC binaries available.
jME is based on a scenegraph implementation but it's a bit more than that. It is more of a Java 3D game engine and API. So it has more built in functionallity than Xith3D does. Currently it only supports lwjgl but they are working on jogl support. Personally, I prefer lwjgl anyway.
Hope that helps. [ September 21, 2004: Message edited by: Gregg Bolinger ]
