Hi,

I was wondering how POV is able to render coherent noise. Is it truly 
infinite, or just nearly? I've never seen a repeat, but perhaps it 
occurs just past the limit of observation.

I'm coding a simple demo of randomly generated topography, with the 
ability to scroll around the landscape. The only noise generators I've 
found reluctantly admit that the noise is "nearly infinite". I want an 
absolutely infinite landscape, but I don't know if it's even possible. 
Thanks~

Sam
