First Image

The first step was to set up a way to write an image to file. This paper uses the PPM file format, which I also used in my last ray tracing project. PPM is a really convent format to write to since all you have to do is write out a integer value from 0-256 for each pixel’s RGB. A down side is that the file size is relatively large.
