Class TransparencySortController

java.lang.Object
  extended by com.sun.j3d.utils.scenegraph.transparency.TransparencySortController

public class TransparencySortController
extends java.lang.Object

This class controls the Transparency Sorting scheme used by Java 3D when rendering transparent objects. By default (and in all previous versions of Java 3D) objects are sorted depending on the distance from the viewer of the centroid of their bounds. By supplying a different Comparator for a view using the static setComparator method the user can provide their own sorting scheme. The Comparator provided will be called with 2 objects of class TransparencySortGeom.

Since:
Java 3D 1.4
