I am working with very polydata (e.g. 2.000.000 points and 4.000.000
triangles). When applying fitlers, memory usage quickly explodes. Even
rendering with display lists gets me into trouble.
For saving memory I would like to render the points and ignore the
triangles. I found that I can use vtkPolyData and create a single cell with
points 0,1,2,3, ... n-1. This seems like a waste of memory to me.

Is it possible to draw simply draw all points in a vtkPointSet ?
