[vtkusers] mesh generation for point cloud data

[Maxwell, Thomas P. (GSFC-606.2)[COMPUTER SCIENCE CORP]]

Also, if the points are ordered (e.g. as in scan lines) it is MUCH more efficient to build the mesh yourself (construct a vtkPolyData instance) using the natural ordering of the data.

Hello,

Look at vtkDelaunay2D and vtkDelaunay3D.  I believe this is what you are looking for.

Hello every one,

I have a point cloud data, representing a 3D face. I'm wondering if there is any way that I could generate a surface mesh out of this point cloud. I mean I have a bunch of points in 3D space and want to have a surface mesh for them by triangulation. Could you please let me know if it is possible to do something like that in VTK?

Thanks a lot,
Rane
