If ideal solution could be easy it would be done probably.
AFAIK at this moment you have three ways to do it:
a) accurate but limited in geometry - fast parse and slow render - isosurface
b) aproximation - slow parse and fast render - store vertices of mesh in
array, displace in loop, create final mesh
c) other program with export to pov

All this tesselation stuff p.u.p, mesh manipulation things are small steps in
a way towards displacement maping.
