Hello,
So far my ray tracer is coming along quite well! It currentley only supports dynamic lights (cast shadows), sphere objects, and polygons (ONLY show reflection, polys do not show up IN reflections.. yet).

I have tested it with 3 dynamic lights, animated one light, 4 spheres, running at a 4 reflection-ray limit (for serial reflections). It runs at what GS says "230 fps" which I assume is basically faster than what GS can calculate as this is not a realistic speed.

--------------------------------------------------------
SO, I am actually in need of some help with the project!
--------------------------------------------------------

I have been trying to add block/box object support but I can't get the collision detection to work correctley (the simple dot quad formula only applies to spheres).

I would appreciate any help with a BBOX shader fragment code in particular.

I am also planning on adding full polygonal collision support and caustic/refraction traces as well.

PLEASE CONTACT ME and help me out! So far this is the COOLEST thing I have ever made let alone seen in GS, it would be awesome to complete this project and make a fully ray-traced game in GS!
