I am writing a program, that as input, I have a huge (10^6 elements) 3d mesh (with hexagonal shaped elements), and I want to realtime render it, but not as real-time as a game. It just can show the scene and rotate, zoom and pan. The most important point is, I don't need any special lighting nor any shadows. Also, the objects to render are static, and they do not move. My object hasn't any textures.
I've read about
ray tracing methods, but I don't know if there is any good libraries for this purpose, or I have to implement everything by myself.
Thanks a lot.
