[vtkusers] whats the difference?

[Amy Henderson]

Hi David,

No they don't do the same thing. vtkSurfaceReconstructionFilter samples 
your data onto a regular 3D grid (vtkImageData). You then have to contour 
the results of this filter at 0 to retrieve the surface of your data set. 
vtkDelaunay3D constructs a tetrahedral mesh from the points in your data. 
(vtkDelaunay2D creates a triangle mesh.)

The online documentation for these classes are listed below.
