Hi all, name's Robin. I heard about this project earlier today through Phoronix and it sounds really interesting. I'd like to get involved in the development side of things, as I have quite a bit of experience in graphics programming (some in AI, too, but not enough to be of assistance I think). I've cloned the SVN and it all looks very easy-to-follow- although I've only been looking at the terrain and water rendering sections so far. I wrote some small improvements to the fresnel calculations for non-fancy water, including calculating them per-vertex instead of as a constant value, as a little test to myself, and I wondered if anyone would be interested in them? And if so, how may I submit? Also, is anyone working on terrain self-shadowing? It looks like it's missing from an otherwise production-quality shadowing engine, and I think it would make steep inclines and cliffs look slightly less... Flat. If nobody is, and my code is deemed good enough, I'd be willing to give it a go. Thanks for any replies or sneers of disdain, Robin
