[vtkusers] Why does vtkRenderWindow refresh so slowly?

[Chunyan Jiang]

Dear vtk-users,
I use vtkRenderWindow to render three vtkRenderer. When I refresh the
vtkRenderWindow by vtkRenderWindow->Render(), it is very slow. How can I
speed it up? I don't know if my data is too big or there are some other
reasons. There are three data sets rendered in vtkRenderWindow. They are:
256*256*50 rendered as raycast; 145*55*50 rendered as data set; one 3ds
object 561K.
Any hint is great appreciated!

Chunyan
