I wrote a proximity pattern which is included in MegaPOV, it calculates 
a value which depends on the distance from the surface of an object by 
shooting rays at it...I am not sure how good it would be for 
displacements though. It might just be too slow for an isosurface, 
unless it could be calculated once and output as a density file.
