A simple implementation of vtkCellDepthSort. 
<p>
<a class="el" href="a00243.html" title="A simple implementation of vtkCellDepthSort.">vtkCellCenterDepthSort</a> 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.

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 <a class="el" href="a00722.html" title="dynamic, self-adjusting array of vtkIdType">vtkIdTypeArray</a> returned from GetNextCells is a cached array, so do not delete it.
