This can be done with bicubic patches as Micha Riser suggested. But there
are other soultions. For some distortions you can use isosurfaces. Just have
to define function of distortion. It is rather complicated and possible only
for "function expressable" deformations (is this acceptable term?). If you
can define your edges as splines you can use macro to fill area enclosed in
splines - take a look at MMMM macros by Ingo
