[Insight-users] Display itkVoronoiDiagram2D

[Steffan]

I've replace my VTKPolyDataWriter<VoronoiDiagram2DType> by VTKPolyDataWriter<VoronoiDiagram2DType::Superclass> and it compiles.
And I end up at the same point as you David, Paraview crash.

I've looked up to the voronoi.vtk:

# vtk DataFile Version 2.0
File written by itkVTKPolyDataWriter
ASCII
DATASET POLYDATA
POINTS 0 float
POLYGONS 5 29
5 0 0 0 0 0
5 0 0 0 0 0
4 0 0 0 0
5 0 0 0 0 0
5 0 0 0 0 0


There are clearly some missing data in order to display the voronoi diagram, which explain why Paraview crash.
I think there is a different data structure between Mesh and VoronoiDiagram2D.
By using VoronoiDiagram2D::Superclass (which is Mesh) as template value for VTKPolyDataWriter, we are writing only the data structure in common between Mesh and VoronoiDiagram2D.
And if you use VoronoiDiagram2D as template value for the writer, you will end up with the same compilation errors I had:

itkVTKPolyDataWriter.txx:191: error: invalid conversion from … to …
itkVTKPolyDataWriter.txx:225: error: invalid conversion from … to … 
itkVTKPolyDataWriter.txx:240: error: invalid conversion from … to …
