[vtkusers] How to get a fixed number of vertices after decimation in VTK

[rogertrullo]

I am working with vtk for 3D mesh processing. I have a mesh, and I am using
the function vtkDecimatePro() to get the reduction done. The function
accepts a TargetReduction, that is related to the reduction in the number of
triangles (percentage). The problem is that I need to have a fixed number of
vertices, say for example I want all my meshes to have 2000 vertices.
Currently I am doing this in a software called openflipper which allows to
constrain the decimation to a fixed number of vertices. However, in VTK I am
not sure how to accomplish this task. Thanks for any suggestion.
