Load a .obj file with Java3D and use it in JOGL?

I'm using Java3D and JOGL, but I'm having a hard time figuring out how to do this by looking at the javadocs. I want to load a .obj file (other formats would be nice, too) and render it using JOGL.

Here's a loader class. It returns a Scene from a filename. How can I use this Scene in JOGL?

Thanks. I'm new to JOGL and Java3D.

There is a OBJ loader using JOGL here: http://github.com/sgothel/jogl-demos/blob/master/src/demos/util/ObjReader.java

The Scene object provides no access to triangles, which is what you would need to use in JOGL. In fact Java3D and JOGL are two very different libraries, and I wonder why you are using them both together (or how). Java3D is a scene graph API while JOGL is just a wrapper to low-level OpenGL. Are you aware of these things?

In any case, you'll need to write an OBJ loader for JOGL. It's not a hard task though! Just find some OBJ specs and write a loader which parses the file line-by-line into whatever format you choose to send to JOGL.

Or, stick with one of the two libraries. I see no sense in using both. Either you want to use low-level OpenGL, or you want the convenience of high-level Java3D, right?
