[vtkusers] Polygons with holes

[Andrew Wilford]

Hi,

I am 2 days new to VTK and am trying to determine if what I need to do is
even possible. I need to model a 3D metal sheet with holes drilled in it,
essentially a 2D polygon with holes, extruded along the z-axis. How do I
represent a polygon with holes? Must I tesselate the polygon into polygons
which do not have holes? I have tried to use the vtkClipPolyData function,
but I am not getting very far.

Thanks in advance for any advice you can offer.

Regards,
