Self shadowing bumpmapping updated
Thursday, January 15, 2004 | Permalink
The self shadowing bumpmapping demo has been updated to support offset mapping too, which further improves the sense of depth in the picture, and isn't very expensive either.

Andrey S,
maybe I'm just blind, but I don't see any significant difference with your code. I mean, it looks a little different in certain places, but it's not like I can say it looks better or worse.

A very nice bumpmapping technique Humus! I'm not too familiar with this "offset" technique, but does it just multiply different areas of the heightmap with some sort of constant?

It's very simple. It just offsets the texture coordinates according to a height map. The essence of the technique lies in these lines in the shader:
float height = tex2D(Elev, texCoord);
float2 newTexCoord = texCoord + viewVec.xy * (height * 2.0 - 1.0) * 0.04;

Looks good... personally, I like it better without self shadowing on (don't know why, but I think it gives the scene a "cartoony" look)
