I forgot to mention that you may get strange artifacts if the vector
right after the min/max vectors is too high. This is especially true for
curved surfaces. You will have to fiddle with it to achieve a desirable
result. The value right after than should be set to 2 or more. Higher
values give more falloff, and tend to reduce artifacts.
The patterns are 3d, so they can be used for media and isosurface
functions, although these will take a long time to render.
Also, I did not make a fastSSS3 macro to behave like fastProx3. You can
probably make one yourself by looking at the code.
That is all :)
edit:
One last thing. You can transform the object after applying a pattern to
it, but don't expect this to work very well with the SSS pattern.
For SSS you should apply your transforms *first*, and then apply the
pattern to the object and adjust the bounding box accordingly.
The proximity patterned object can be transformed anytime, as it does
not take a light position into account.
