More specifically, can you point me to where the BRL-CAD interface with your current ray trace rendering interface is?  My thought was that if I could adapt my STL file viewer to accept input from that interface it would provide a second rendering method for BRL-CAD.  It would be a stand alone program, of course.  If I could create an interface into BRL-CAD for this OpenGL rendering program, it seems like it would offer a lot of opportunities to later expand that program to also create commands going to BRL-CAD similar to the way you input them now from a text file, except with a point and click kind of interface.

Right now I'm not very good at choosing random solid objects, but I do have experience creating buttons and clicking on them with mouse inputs as part of an OpenGL program.  I have also interfaced with the scroll wheel on the mouse.

Can you point me to where BRL-CAD meshes the solids to generate the ray trace graphics?  I was thinking if I could grab that mesh I could use my STL file viewer to generate a standard OpenGL polygon shaded view of the solid.  It wouldn't be difficult to create buttons and other user interaction features in that kind of window.
