Outline of our program

This post is a simple step by step description of the main points in our program.

Setup scene
Build BVH over the objects
for #number of passes
  Trace the initial beams from the lightsources
  Calculate scattering events 
  Build BVH over the beams
  for #vertical pixels
    for #horizontal pixels
     Check for intersection with object BVH
      Collect intersected beams from the beam BVH
      calculate light from material
      calculate light contribution from beams
