Self Shadows with shader programs.

Check the DirectX 8/9 SDK. There's a self-shadowed spinning Earth example. It can also do it with render-to-texture.

i'm not using DirectX :(

Thanks anyway. Any other suggestion.

There's a guy at http://frustum.org/ who has done an example with horizon shadows, I don't know if that's exactly what you want. It's called DisplacementTexture.tar.gz

Thanks for you answer.

Well the only problem is that those shadows don't look real enough.

:(


btw.
At the moment Im doing my rendering with:
vertex textures in the vertex shader plus
bump mapping in the fragment shader.

The only thing a need now is self shadows, but all algorithms are too complex to run them in real time.

The fastest self-shadows that I can do at the moment are using the shadow part from relief mapping.

Any other suggestion?


Thanks.
