We are about to start a msc project on adaptive geometry modeling in
dolfin. The idea is to introduce surfaces in dolfin, representing the
"exact" geometry, separate from the mesh representing the "approximate"
geometry, to be able to adaptively refine the mesh geometry approximation.
This is a continuation of our previous work on parallel adaptivity in
dolfin (currently discussed in another thread), and also here distributed
parallel computing issues will be considered from the start.

It comes down to introducing a class Geometry, where surfaces are
represented in a suitable way, typically close to a standard CAD
representation (e.g. NURBS), with the basic functionality being a
projection of an arbitrary point onto a surface, and the ability to import
standard CAD surfaces.

This should be fairly orthogonal to other ongoing work in dolfin as far as
I am aware, but we are happy for any input to consider.
