Fractal Clouds

This animation is 60 images of a 2d plane moving through a 3d fBm noise space. The 2d plane was translated in the xz direction (a slope of 1) between each frame. The value returned from the function was used to scale the red & green intensities. The blue intensity was held constant at 255. Any negative values were clamped to (0,0,255). The noise function was Ken Perlins noise3 function from the book Texturing and Modeling - A Procedural Approach.
