[vtkusers] Delaunay2D and SetTransfrom

I have a set of points lying on a surface which is similar in shape to 
two thirds of a sphere, and I want to use Delaunay2D to generate the 
surface. The default behaviour of ignoring the z coord doesn't work in 
this case, so I need to do some kind of stereographic projection onto 
the 2d plane. Is this possible? If so, how do I specify the transform 
(the x and y coords of each point need to be scaled by some function of 
the z coord).

Thanks,

Will
