[vtkusers] How to visualize thousands of actors with good performance

Hi,

 In your particular situation, would it be possible to use a single mapper for all your objects? Perhaps it could be a viable solution. For example, if you wanted to show 10000 spheres, you could do:

1) 10000 actors, 10000 mappers -> very slow
2) 1 actor, 1 mapper -> very fast
3) 10000 actors, 1 mapper -> acceptable speed
