Hello.

I've updated my fish-eye effect code with added comments. The effect is based on Jason Waltman's work, which in turn references a paper by Devernay and Faugeras on correcting distorted images. The paper details a method for determining distortion and converting images to a standard pinhole camera model. My code produces the desired fish-eye effect, and I've provided the C# source code for download. While I haven't fully delved into the paper, it seems to offer more in-depth analysis of image distortion correction.
