vtkVisibilitySort

Section: Visualization Toolkit Rendering Classes

Usage

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.

.SECTION Note The Input field of this class tends to causes reference cycles. To help break these cycles, garbage collection is enabled on this object and the input parameter is traced. For this to work, though, an object in the loop holding the visibility sort should also report that to the garbage collector.

To create an instance of class vtkVisibilitySort, simply invoke its constructor as follows

  obj = vtkVisibilitySort
