[vtkusers] surface mesh / terrain decimation

[Sébastien MARAUX]

Hello,

 

Is there any alogrithm implemented in VTk which could handle a several
millions points terrain mesh and decimate it to a few thousands points ?

 

I am expecting algorithms such as quad tree, Delaunay point insertion
method or others.

vtkDecimatePro does not seem to give as good results as I expected.

 

I would also appreciate any algorithm idea that I could implement.

I am currently only using subsampling for decimation.
