29 // To add a new cell type, define a new integer type flag here, then
30 // create a subclass of vtkCell to implement the proper behavior. You
31 // may have to modify the following methods: vtkDataSet (and subclasses)
32 // GetCell() and vtkGenericCell::SetCellType(). Also, to do the job right,
33 // you'll also have to modify some filters (vtkGeometryFilter...) and
34 // regression tests (example scripts) to reflect the new cell addition.
35 // Also, make sure to update vtkCellTypesStrings in vtkCellTypes.cxx
36 // and the vtkCellTypes::IsLinear method in vtkCellTypes.h.
37 
38 // .SECTION Caveats
39 // An unstructured grid stores the types of its cells as a
40 // unsigned char array. Therefore, the maximum encoding number for a cell type
41 // is 255.
