[vtkusers] What's more efficient ?

[De Boer Ingo]

Hi,

I want to animate some data. The x,y positions stay the same.
The z-value is changing. Now, I can either:

1. make 1 Actor and change the points on each animtion step

or

2. make i Actors (before the actual animation) and only show the
current Actor on each animation step.

any comments on this one?

greets
  Ingo
