[vtkusers] multipass rendering?

[clyne at ncar.ucar.edu]

Hi,

I'm trying to render a scene using different light parameters for
different actors. Essentially I need to render a frame with some actors
with a light in one position and other actors with the light in a
different position.  vtk's scene graph represenation doesn't seem to
realy permit this. Any pointers on how i might accomplish this?

thanks - jc
