Sorry, what I wrote was maybe a bit misleading. I do not use any of
the OpenGL/GLUT 3D features. All I do is normal raytracing and using
OpenGL's 2D raster image drawing capabilities to display the result.
What makes this more useful than existing output classes is that I
do not simply loop through all pixels to render them, but I do hierachical
refinement so that you see a coarse image pretty quickly. Overall
rendering time is of course not better than "normal" rendering.

I render in the idle function. Not ideal, but works reasonanly well.
I don't want to use threads, since this cannot be done in a platform
independent way.

This would be nice of course and I already thought about doing that.
But I basically only would show bounding boxes and some simple primitives.
Everything else is quite some work. It would be nice though. If someone
is interested to do it, it would be great!
