I am writing a game (no link yet) and I need some assets. So the obvious thing to do is to parse some 3D file format and get the data out of it that I need. I have tried a couple of formats and implemented some, and the following article describes the file formats I've encountered and tried to use.
A while ago I finished playing From Dust which I enjoyed a lot. What impressed me about that game was the application of landscape changes by erosion. One drawback of the tool Lithosphere I wrote earlier is that it can't do any form of hydraulic erosion. I decided to write a test in WebGL to see if a few simple algorithms could be used to shape a landscape according to hydraulic erosion.
