Thank you!
Note that displacement mapping is done using .obj or mesh2 files as 
input in Poseray. I really have no idea if HG POV can do this. However, 
I guess that isosurfaces could do the job but probably would be much 
slower (in render time) than the way through Poseray which generates a 
"heavy" output .geom file but renders almost as fast as a non-displaced 
object.

I gave some sort of tutorial last year:
