Detailed Description

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.

Member Function Documentation

virtual const char* vtkCellCenterDepthSort::GetClassName  )  [virtual]

Reimplemented from vtkVisibilitySort.

static int vtkCellCenterDepthSort::IsTypeOf const char *  type  )  [static]

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

Reimplemented from vtkVisibilitySort.

virtual int vtkCellCenterDepthSort::IsA const char *  type  )  [virtual]

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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkVisibilitySort.

static vtkCellCenterDepthSort* vtkCellCenterDepthSort::SafeDownCast vtkObject o  )  [static]

Reimplemented from vtkVisibilitySort.

virtual void vtkCellCenterDepthSort::PrintSelf ostream &  os,
vtkIndent  indent

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 vtkVisibilitySort.

static vtkCellCenterDepthSort* vtkCellCenterDepthSort::New  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual void vtkCellCenterDepthSort::InitTraversal  )  [virtual]

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.

Implements vtkVisibilitySort.

virtual vtkIdTypeArray* vtkCellCenterDepthSort::GetNextCells  )  [virtual]

Implements vtkVisibilitySort.
