[vtkusers] What is the principal of mesh decimation in vtkDecimatePro?

[Wenlong Wang]

Hi, All

I'm using the <vtkDecimatePro.h> to decimate my 3D meshes. However, I am
not sure the decimation is random in nature, or it follows a principal to
choose the decimated points?

Many thanks.

Kind regards
Long
