[vtkusers] Reasonable use of anti-alias on screen

[Christophe Franco]

Hello everybody,

I'm trying to find reasonable settings for anti-aliasing. I use 
LineSmoothingOn on the RenderWindow, along with SetAAFrames(...). The 
problem is to find a proper value for the last method.

I often read that people use SetAAFrames(16), which seems completely 
impossible for the tests I have made. I display a rather simple 3D 
wireframe grid, the test PC is a P IV 2.4Ghz, with 1Go of RAM, 64MB of 
video memory, in 1024x768. As soon as I use SetAAFrames with a parameter 
over 2, it becomes so slow that it is almost impossible to move the view.

Have I missed something important, or is it normal that the view is so 
slow as soon as I use SetAAFrames ?
