At
the time this was created, version 3.0 of Lightwave only provided a single
texture per attribute channel (color, luminousity, diffusity, transparency).
Thus, this was an attempt to get as much detail and effect out of these
4 channels as possible using only the built-in procedural (mathematical)
textures. For example, the main vortex has a transparency gradient
texture to feather the edge, while a color gradient gives it the blue
to purple transistion. A fractal diffuse texture creates the spiral
bands, while a marble texture on the luminousity channel gives it the
fine cloud-like detail. This is an original design of the
author based loosely on the Star Trek: Deep Space Nine wormhole concept.
