Visibility of individual elements

[Ben Held]

Hello,

I am displaying large structued meshes (vtkStructuredGrid) using VTK.  Each
element may have a different material, and the end-user will want to make
elements of a certain material invisible.  Must I have a separate vtkActor
for EACH element so I can make the proper actors invisible?  Or is there
another, easier way?  If I have to have separate actors, is this going to
be a major performance issue?

Thanks,

Ben
