[vtkusers] Animation speed

[David Gobbi]

Hi Bharati,

If there are less than around one hundred time steps, the fastest way to 
animate is to create a separate actor for each time frame.  Then set 
VisibilityOff() for all the actors except the one you want to show.  The 
reason this is fast is that it pre-loads all the geometry or texture 
data that is needed for the render onto the graphics card.

There are lots of other tricks, but they will depend on the type of your 
data.  If you have a mesh, you can use vtkGeometryFilter to extract just 
the surface of the mesh, and vtkDecimatePro to reduce the number of 
polygons.  With images, vtkImageActor2 is the most efficient display method.
