|
|
* @brief an abstract base class for classes that build
|
||
|
|
* topological links from points to cells
|
||
|
|
*
|
||
|
|
* vtkAbstractCellLinks is a family of supplemental objects to vtkCellArray and
|
||
|
|
* vtkCellTypes, enabling fast access from points to the cells using the
|
||
|
|
* points. vtkAbstractCellLinks is an array of links, each link representing a
|
||
|
|
* list of cell ids using a particular point. The information provided by
|
||
|
|
* this object can be used to determine neighbors and construct other local
|
||
|
|
* topological information.
