[vtkusers] clipping 2D polygon with another 2D polygon

[Nicholas I. Walker]

Cory,

So you're saying there's currently no way to perform 2D Boolean operations in VTK?

Thanks,

Nick

Even if you could use 5.10, the vtkBooleanOperationPolyDataFilter class doesn't support 2D boolean operations. It wouldn't be impossible to add, but there are no plans yet that I know of to support this.

I should really add a note about this limitation to the documentation...
