[vtkusers] Control VTK frame rate

[David Thompson]

Hi all,

You might try the vtkGlyph3DMapper. It can take in a bunch of "source" polydata objects plus a set of points with point-data specifying orientation, scaling, and the index of which polydata to draw at each point. More recently, David Lonie added a way for it to take in a multiblock dataset and let each point specify the index of a top-level block to render (again, with point-data specifying per-instance transforms).

That would leave you with a single actor and an easy way to update per-instance transforms.
