Photon Mapping
May 2005
Description
This program impliments the use of a photon map to simulate global illumination and caustics into the raytracer we've been working on.
Source Code
The source code consits of the following files:
- rayTracer_03.C
- vector.H
- vector.C
- color.H
- color.C
- materials.H
- materials.C
- ray.H
- ray.C
- matrix.H
- matrix.C
- objects.H
- objects.C
- myMath.H
- myMath.C
- PhotonMap.H
- PhotonMap.C
There is a Make file that compiles the program
Problems
The biggest problem I had was scaling the power of the photons so that they wouldn't blow out the image. I ended up scaling the photons power by 0.125. This is
no where near where it should have been (1/number of emmitted photons). The only thing I can think is that I wasn't using the correct start power for the
photons.
