[vtkusers] How to render?

[Stephan Theisen]

Hi Folks!

I've one question. I try to render a volume with the vtkVolumeProMapper, 
but I always get a black screen.
So I used the function -->Render(renderer,volume) which is implemented 
in the Mapper. But now I've little problem
to include it in my program, because the volume must be a kind of 
imagedata.  Have anybody an example for the correct
use of the vtkVolumeProMapper.Render function or a link where I can get 
some useful informations?

Thanks in advance

Stephan
