[JAVA3D] OpenGL - Need help :(

[John Hynd]

Ok, I'm in a wee dilemna here.   In Java3D, is there any way to actually get at the underlying OpenGL, or are you restricted to using the high level API priovided by Java3D whihc then in turn uses OpenGL. I posted a while ago, about whether to use GL4Java (www.jausoft.com) or Java3D. I know OpenGL pretty much, but Java3D is new to me.   If there is any way of programming in actual OpenGL syntax in Java3D I'm made. GL4Java is pretty ill supported and my experience of Java3D is that, given this group, and a few others, help is readily at hand and this greatly enhances the feasability of using it.   Things I need to do, include a particles system, or particle manager rather that can handle blood, smoke, fire and sparks. All over the net tutorials are available for this in OpenGL and I have already made something using OpenGL similar. I also need a terrain system, that will probably be fixed (i.e. not randomly generatable) across a few varied landscapes. We are also loading in Hlaf Life MDL fomat models which we currently have up and running (minus textures as of yet) in Java3D. And finally, a sky dome sort of system, effectively a box probably, that will be textured but will change colour depending on the time of day. Kind of :)   Any advice anyone can give me as to what path to take.   Cheers, John Hynd. Thanks loads in advance. I am really not sure what to do.
