A simple implementation of vtkCellDepthSort.
vtkCellCenterDepthSort is a simple and fast implementation of depth sort, but it only provides approximate results. The sorting algorithm finds the centroids of all the cells. It then performs the dot product of the centroids against a vector pointing in the direction of the camera transformed into object space. It then performs an ordinary sort on the result.

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.

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.
