00015 /* .NAME vtkCellType - define types of cells
00016 // .SECTION Description
00017 // vtkCellType defines the allowable cell types in the visualization 
00018 // library (vtk). In vtk, datasets consist of collections of cells. 
00019 // Different datasets consist of different cell types. The cells may be 
00020 // explicitly represented (as in vtkPolyData), or may be implicit to the
00021 // data type (as in vtkStructuredPoints).

00027 /* To add a new cell type, define a new integer type flag here, then
00028 // create a subclass of vtkCell to implement the proper behavior. You 
00029 // may have to modify the following methods: vtkDataSet (and subclasses) 
00030 // GetCell() and vtkGenericCell::SetCellType(). Also, to do the job right,
00031 // you'll also have to modify the readers/writers and regression tests
00032 // (example scripts) to reflect the new cell addition.
