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.

I successfully implemented a fish eye effect! I peeked at Jason Waltman's code for inspiration and adapted it to C# using the Tiger Image Processing Library. Now I even understand polar coordinates better. It involves converting Cartesian (x,y) coordinates to angles and distances from the center of a circle. The effect itself figures out which pixels need distorting and then calculates their new positions.
