I am posting to ask if anyone is against changing
vtkCell3D API local ids representation. Currently they are stored as
int*, which forces the user to make copies of the ids in a
vtkIdType* if one wants to use an algorithm based on point ids, like
vtkPolygon::ComputeNormal for example.
They are mainly accessible to the user from
Changing those ids to
const vtkIdType* would break the API, any ids written as
int* would have to be changed to
const vtkIdType*, but I think it would be worth being able to use those ids in VTK filters, which is mostly not the case presently.
