| I was looking for some rusted metal shader for a scene I’m working on and I wanted it to be fully algorithmic, no bitmap at all.
The main idea is to have blurred reflection with some dusty bumps in the less accessible areas. This require several component to be layered : diffuse, noise, ambiant occlusion, blurred reflection …
|
Here’s how it works, in pseudo-code :
amb_occ = ambiant_occlusion("cone=wide","distance=small","fallof=high"); C = diffuse() * noise("grey","orange") * amb_occ; C += specular() * noise() * amb_occ ; C += reflect("blur") * amb_occ ;
Quite simple, eh ? 😀
Still amazing 🙂
I wish the flash animation could be a little bit slower so I could take time to understand your approach. 🙂
Et sinon comment tu fais pour avoir des "catégories" dans ton blog ? (rendering styles, input, etc..)
J’aimerais bien convertir mon vieux blog en truc automatique comme celui ou làou blogger etc…
Merci 🙂
