[vtkusers] Reduce points on the surface model

[Wenlong Wang]

Hi, David and all

Thank you for your reply.

I think vtk does not provide such a function, but I find an alternative
way, though it is a bit informal. That is using vtkCleanPolyData, then by
set a suitable tolerance, you can controlled the number of filtered points.

Regards
Wenlong
