Wow, I wish that this was around a year and a half ago. I was working on a pet project of mine to do finite element analysis on PCB Gerber files. One of the biggest stumbling blocks that I ran into was taking a 2D image parsed from a Gerber (side note: Gerber files have a really wacky yet interesting format and structure) and triangulating it. I had wanted to use DT to clean up edges and thin traces in the model but I just couldn't seem to grasp it, as interesting as the math was. It's a shame that I never finished it, maybe I will need to get back to it one of these days.
