[vtkusers] interactor ->good render, non-interactive render->poor quality

[James C. Moore]

I've scoured the documentation (except the source) and have yet to resolve 
this problem which has puzzled and now plagues me.  If there is a simple 
answer, I would love to know it:

When rendering a 3-d polydata scene, if the camera is controlled with the 
interactor, the renders all look proper.  If I write a script to move the 
camera through the exact same path, the faces are not rendered properly.
They appear to flicker as if the lighting is not being calculated properly 
and sometimes the faces appear to disappear.  One touch from the interactor 
and they re-appear, properly rendered as before.   I'm using the default 
light,camera, interactor, and only setting the opacity of the objects (set 
to 1.0 for the test).

I am using on vtk3.2 on Windoze and Linux.   I'm not sure if it does this 
on LInux, but it is PRONOUNCED in windows.  

Any advice would appreciated.  Send address for cash reward...  (except for 
Will, because this is probably his fault  :))
