[vtk-developers] vtkUnstructuredGrid - Not rendering Overlapping Cells

[Sebastien Jourdain]

VTK has other type of data structure such a composite-dataset / multi-block
which let you create a dataset that is composed of multiple dataset (i.e.
Unstructured grid in your case).
And what you do is basically share the same vtkPoints across all your
unstructured grids which will then be gathered by the composite dataset.
and rendered as a single dataset.

Hope that explain a bit more,

Seb
