[vtkusers] vtkCastToConcrete overhead

[Rajesh Bhairampally]

Hi,

I have a large set of data in vtkDataset format and am reading it with vtkDatasetReader and decimating it through vtkCastToConcrete.GetPolyDataOutput(). I would like to know if using vtkCastToConcrete causes any significant overhead when, especially, dealing with very large datasets (~10 mil grid cells).

Thanks,
Rajesh
