VTK Dataset creation from custom data

Hello, dear Mathieu!

I have custom data in my own specific data format, and I want to convert it to VTK Dataset format. I know that original data was a mesh of hexahedrons, however my custom data format foes not contain topology data.

Is there a way to get the cells formed (the topology) given only the geometry?

I would be very much grateful for any support


This is more of a question for https://discourse.vtk.org/, in any case, you can read the documentation for vtkUnstructuredGrid here: VTK: vtkUnstructuredGrid Class Reference
