grass rendering tutorials anyone?

Hi,
Does anyone know where i can find tutorials on 3d grass rendering (no vertex/pixel shaders)!
If you have any ideas fell free to share them.

Are you interested in a single blade of grass? A small patch? Or a field?

Let’s say a field.

The super crappy shell method: http://developer.nvidia.com/object/Grass.html

A much nicer method: http://www-evasion.inrialpes.fr/Membres/Frank.Perbet/home/prairie/
