vtkUnstructuredGrid output from a vtkLinearToQuadraticCellsFilter
I'm new to VTK (I'm using VTK8 C++ API). I have a vtkUnstructuredGrid
dataset, consisting of linear triangle/tetrahedral cells, and I'm trying
to convert it into a dataset of quadratic cells with a
It works fine on visualization. Now, I would like to get an
vtkUnstructuredGrid dataset from filter but I didn't manage to do that
since I didn't clearly understand the documentation. How I can get an
output dataset from a filter ?
