Here are some procedural textures that I have made for Imagine for Windows. They will only work with the full windows version, not the LE, demo or DOS versions.

Fractal Bump texture

This texture is great for making realistic looking rocks and mountains etc. The texture can also be used with Alan Bucior's ABColorHeight texture.

Concentric texture

This texture tries to simulate the concentric reflections that can be seen on some metal buttons and dials.

Sample object

Fractal Noise texture

The roughness of the fractal noise can be set using the Octaves control. When Mirror transition is checked, the mapped color gradient will be: color2 -> color1 -> color2.

Filter clip controls how much of the texture will be visible. Invert filter clip reverses the effect of the filter clip control.

The texture can be used in several layers for great effects.

When Only if Lighter is checked, the calculated color will only be used if it is lighter than the underlying color.

The texture can be set to affect most of the surface attributes. In this image, it was used for the Color of the rock formations (a couple of layers of the Noise bump texture were also used) and to affect the Fog length of the fog object, a primitive plane positioned so the camera would look through it. The Ripples texture was used for the waves.

Ripples texture

This is a bump texture that simulates the ripples of a water surface. It will only work properly when applied to an object that is flat in the world X-Y plane. This isn't really a problem since a water surface is always horizontal.
