Fur Rendering

i think microsoft has done some work with them. real-time rendering has some info on it too

Are they not just faked still? I thought most people used a similar method to making grass, only more detailed, using billboards.

I used a (relatively old) fur rendering technique to make 3D grass. Basically you take a texture with an alpha channel made up of noise and stack 5 or 10 or more layers (or shells) on top of eachother with very limited space in between. Go to the RoboBlast link in my sig to see the game. It runs pretty well on a PIII 600 with TNT2.

Here you can find one of the best fur demos I have seen
with code

Hughes Hoppe was the microsoft guy with a paper on this. he uses shells and fins method (layers of object aligned billboards). IIRC there was another guy who wrote a demo that implemented this method, and he put it for download (with src) on nehe.gamedev.net (or maybe the link was from there?)

Either way, the paper is called "Real Time Fur Over Arbitrary Surfaces" and is by Jed Lengyel, Emil Praun, Adam Finkelstein and Huges Hoppe. You can get it from Hoppe or Lengyel''s website i think.
