LibNoise question

Hey. How do I specify a range of valid sound? I want to be able to enter very large x,y,z values(between -12 million to +12 million) and still get coherent noise.When I specify values this big though I always get zero. I am very new to noise, so thank you for any help.

If you are calling the functions with (x,y,z) coordinates that are integers, and the basis function is Perlin's gradient noise, you are going to get 0. Gradient noise is always 0 on the integer lattice, due to the way the noise is generated. You can tinker with the frequency parameter of any fractal functions to get better results.

Ah I see thank you for the info. I am very new to noise and trying to piece things together as I go. Basically I have a cube of points(12million^3), and I want to be able to call a noise function for any point in this cube and get a coherent noise value. How would I go about doing this?
