This builds upon smallpt and borrows a few things from Ray Tracing in One Weekend:
- The camera(I just couldn't understand all the magic constants in smallpt)
- The formulas for dielectrics and lambertian reflection
I ultimately plan to port this to the GPU, but until then I need to sort out some other things:
- Implement a BVH for fast intersection testing
- Make the rendering process progressive
- Probably replace the current method for random number generation(maybe something like a xorshift will be much faster)
