Not only is it compiled in, the board size is hard-coded. (Its a demo so far..) I wanted to see how fast it might work with different rendering schemes. I'd have posted code if it wasn't full of _evil_ hacks at the moment. Once I've a better feel for the direction this might go in, I can tidy up the code and make it useful. Surprisingly, it wouldn't be too hard to switch out the GL code if desired. You just replace some setup code, and bits of the expose, configure and realize handlers for the drawing area. The one rendering method which I wanted to try out (but haven't had satisfactory results from yet) is using the cairo-glitz backend to make cairo-calls do native OpenGL things. It was even slower than native Cairo when I tried... felt like it must have been hitting loads of software fallbacks in mesa. Whether the 3D has any useful purpose other than looking "bling" and to help me learn little GL programming, is debatable. Still.. many packages can / do provide 3D board views.. I'm just not sure if gerbv is the right place for it.
