[vtkusers] How to use VTK for many small datasets ... ?

[tutu lamotte]

OK... so VTK should be memory efficient for huge
datasets ?

Let says i must display 10000 spheres based on one of
the 2 following mechanism. Which one is recommended?

1) 10000 sphere polydatas connected to 10000 actors
2) 10000 sphere polydatas connected to 1
vtkAppendPolydata and one actor.

Surprisingly, solution 2 takes up to 3 times more
memory space!

Any suggestions?
