[vtk-developers] polygonal prism

[John Platt]

Hi,

If you triangulate (even without creating new points) it causes problems
viewing edges since it exposes all the internal triangulation (nonlinear
cells will demonstrate this).

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
