Hi David,<br><br>
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.)<br><br>
The online documentation for these classes are listed below.<br>

<blockquote type=cite class=cite cite>Hi Everyone,<br>
Thanks for helping me out on the Contour plot. I did the vtkDelaunau2D
and then did the contouring. It work very well.<br>
Thanks again.<br>
Now I have a doubt, I have used vtkSurfaceReconstructionFilter to
construct a surface out of a vtkUnstructuredGrid. <br><br>
Does'nt vtkDelaunay3D do the same thing too?<br><br>
So whats the difference?<br><br>
Somebody please clarify<br>
Thank you,<br>
