[vtkusers] avoid ray-casting

[John Biddiscombe]

Use a vtkLODActor for the volume, the Before you fiddle with the tube filter
call

Renderwindow->SetDesiredUpdateRate(A very small number)

after you finished fiddling, call

Renderwindow->SetDesiredUpdateRate(15 or somethihg like that)

you may need to use a few more calls, but should help you get started.

See Also IntersactorStyle DesiredUpdateRate and StillUpdateRate
