Ah yes, I saw that one on GameDev. :) May want to explain a bit, like you did on that forum.

Yeh sure.

I use a really small noise texture, no more than 64x64, that way I dont abuse the cache, and then I apply it at different frequencies and perturb x and z due to altitude to create cliffs.

The secret is keeping the texture small... then the rays go through ALOT quicker.
