Procedural surfaces (Definition)

A means of space filling an area within an HTML Element object using a shading algorithm.

This can be a means of making web page downloads much smaller because you specify an algorithm to use to fill a space rather than a pixel image map.

These are the available procedural surface generators you can use with MSIE:

These procedural shaders compute the alpha channel transparency and the pixel color of the area in RGB coordinates.
