[vtkusers] Big number of actors

[Daniel A. Mezentsev]

Hello all !

I'm beginer in vtk and I have following trouble.
While I analysing geometry property of DNA fragment about 500 atoms
(every atom is vtkSphereSource with 20x20 resolution and has own
vtkActor) my programm allocate about 130Mb.
I have computer with 128Mb. How you can see this is critical atomic
cluster size for my computer. Is this normal situation or I can reduce
memory usage.

With respect
Daniel
