[vtkusers] Calculating Dimensions from vtkPoints

[Brian Curtis]

Hi David,

Thanks for your reply.

The bounds will compute x,y,z min/max but not number of points for
each dimension. Number of points is what SetDimensions() looks for. My
point set is large and I was hoping that VTK would have a handy
function to gather that information from large point sets. Is this
possible?
