Abstract class that can sort cell data along a viewpoint.
vtkVisibilitySort encapsulates a method for depth sorting the cells of a vtkDataSet for a given viewpoint. It should be noted that subclasses are not required to give an absolutely correct sorting. Many types of unstructured grids may have sorting cycles, meaning that there is no possible correct sorting. Some subclasses also only give an approximate sorting in the interest of speed.

Return 1 if this class is the same type of (or a subclass of) the named class.
Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.
Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkObject.

To facilitate incremental sorting algorithms, the cells are retrieved in an iteration process.
That is, call InitTraversal to start the iteration and call GetNextCells to get the cell IDs in order. However, for efficiencies sake, GetNextCells returns an ordered list of several id's in once call (but not necessarily all). GetNextCells will return NULL once the entire sorted list is output. The vtkIdTypeArray returned from GetNextCells is a cached array, so do not delete it. At the same note, do not expect the array to be valid after subsequent calls to GetNextCells.
Implemented in vtkCellCenterDepthSort.

Decrease the reference count (release by another object).
This has the same effect as invoking Delete() (i.e., it reduces the reference count by 1).
