Class GeneralizedVertexList

java.lang.Object

com.sun.j3d.utils.geometry.compression.GeneralizedVertexList

All Implemented Interfaces:

GeneralizedStripFlags

 class GeneralizedVertexList
extends java.lang.Object
implements GeneralizedStripFlags

The GeneralizedVertexList class is a variable-size list used to collect the vertices for a generalized strip of points, lines, or triangles. This is used by the GeometryDecompressor. This class implements the GeneralizedStripFlags interface and provides methods for copying instance vertex data into various fixed-size GeometryArray representations.
