Ray tracing

For each pixel shoot a ray R from camera;

pixel = TraceRay(R)

RGBvalue TraceRay(Ray R)

shoot rays to all light sources;

for all visible sources, compute RGB values ri

shoot reflected ray Rrefl; rrefl=TraceRay(Rrefl)

shoot refracted ray Rtrans;rtrans= TraceRay(Rtrans)

compute resulting RGB value from

ri, rrefl, rtrans using the lighting model
