[vtkusers] How to sample points from data set, for visualizing glyphs?

[Bryn Lloyd]

Hi

 

I would like to plot vectors (or other glyphs) of a simulation result.
Typically the result will be a vtkRectilinearGrid with vector valued arrays,
but could also be any other type of vtkDataSet.

 

If I plot one glyph per point the visualization will be crowded and not
interactive. In paraview only a subset of points are used. Is there any
class, which obtains this subset?

 

Thanks

Bryn
