Hufo's little fire

This page present my tests of fur and hair effects. I am interrested in thoses effects since a long time and I coded quite a few programs. The most recent is my winning submission to NVIDIA shader contest :-) .

Here is some screenshots of this effect:

You can download binaries + full source code of this effect: hufo_fur.zip (697 Ko).
Note: this only works on GeForce hardware!

This effect uses a stack of transparent layers to simulate fur. It uses a vertex program to set up the per pixel lighting environment which is rendered through register combiners. Only bump textures are used to demonstrate the added quality of per pixel lighting.

I have done several other (older) effects on displaying and animating fur/hairs. Here is the list:

Teddy Bear

Source Code Included
Teddy Bear
Subject: NONE
Date: 30 september 2000
Description: I said to Otri I'll do an hair simulation code this week.
I've already done a little prog with it (see my website :) ) but it's really unrealistic. I tried to modify it without success. Then I hacked this fur code which display as many lines as your card can handle at 20 fps...
I'm really not satisfied with this prog but OpenGL coding is like that: try an idea and do it successfully or not...
Will do better next time :-)
