Class StripifierStats

java.lang.Object

com.sun.j3d.utils.geometry.StripifierStats

public class StripifierStats
extends java.lang.Object

This class collects statistics on the Stripifier. The statistics are cumulative over all calls to stripify() until clearData() is called.

Since:

Java 3D 1.2.1
