[vtkusers] Fastest way to triangulate ordered Points

[Rackwitz, Karl]

Hey folks,

i would appreciate it if someone could reassure my thoughts.

I get points from an Surface-Scanner which are ordered in an nxm Array.
Which is the fastest way of triangulating these points?

Delaunay2D will take alot of time and i'm positive that a different approach is needed.
Which would you suggest?

1. Write an own specialized method depending on the indices?
2. Use SurfaceReconstructionFilter?
3. Use Polygon->Triangulate?

I thank the person who shares some Knowledge or hints me in a direction.
Cheers,

Karl.
