[vtkusers] Alternative to Delaunay2D - regular grid?

Hello Will,

Thanks for the answer! Looks like I put my question a bit wrong: It's
not a DEM file but a vtkPolyData representing a Digital Elevation Model,
and all the data points are on a 3D regular grid (from a laserscanner
flight).
I suppose an alternative could be a TriangleFilter and/or somehow
changing the cell type of my data from vertex/polyvertex to triangles or
quads. I think you put me in the right direction, thanks again.
