Are there plans to implement surface deformation or *real* surface 
displacement in povray, or would this be too difficult with parametric 
surfaces?  If so, will it be implemented for meshes?  I just think it would 
be a neat addition, and I'll bet someone really smart with strong math 
skills (ie, not me;-) could even write some clever macros for easy 
deformation/displacement/blobbing of primitives using iso surfaces.  Is 
this possible?

  AFAIK a real non-linear surface deformation which works with all possible
primitives is way too difficult to implement in raytracing.
  Currently you can only do them to isosurfaces. You can also make an
approximation with meshes (by moving the vertices).

  You can use the PCM macros for this:

Perhaps you could try this, too:

Don't really know if it will help though: have not really tried it.

Hope this helps,
