The images displayed here are jpegs, so some loss of quality has occured from the original PPM files.
All images after "Tone Mapping with Stripes" also implement tone mapping.
The 1 Million Spheres input files were generated using Dr. Reinhard's spheres.cc code.
The times for the 1 Million Spheres tests were done on a 1.3GHz P4 processor running RedHat Linux 9.
I wasn't able to implement Area Lights in time. I believe it is the only feature I didn't implement.
