I didn't notice your "challenge" was about ray-tracing. Interesting way
of transitioning from OSG rendering to raytraced rendering. It looks
like you put in a lot of effort to handle materials and such correctly,
so that the raytraced version comes close to realtime rendering. Or am I
misunderstanding the two "modes" of rendering and is the one during
interaction also raytraced, but without shadows and only simple shading?
