[vtk-developers] polygonal prism

[clinton at elemtech.com]

Hi,

We're prototyping with a polygonal prism, and we've come across a limitation 
in vtkDataSetSurfaceFilter that a face can only have up to 6 points.
Would the right fix be to triangle the faces of the polygonal prism in 
vtkDataSetSurfaceFilter, or to extend the structure to handle an arbitrary 
number of points.  The '6' limit looks like it comes from supporting the 
pentagonal and hexagonal prisms.

Thanks,
Clint
