Introduction

Source Link

Document

Sets the texture coordinates associated with the vertices starting at the specified index in the specified texture coordinate set for this object.

Usage

From source file:SimpleTexture.java

/**
 * Build a cube from an IndexedQuadArray. This method creates the vertices
 * as a set of eight points and the normals as a set of six vectors (one for
 * each face). The data is then defined such that each vertex has a
 * different normal associated with it when it is being used for a different
 * face. The shape is created with texture coordinates so that when the
 * appearance is set it will use the appearance texture on the surface.
 * //from w w  w  . j  av a  2s  .c  o m
 * @return Node that is the shape.
