EXAMPLE (click to run): The following example illustrates four variations of the PixelTexture node (see Figure 3-41). Each of the four maps a PixelTexture onto a simple, rectangular IndexedFaceSet. The first three use the same TextureCoordinate node to repeat the texture three times along both axes of the rectangle. The first object shows how to specify a one-component, gray-scale texture and how the diffuseColor of the Material can be used to tint or brighten the texture. The second PixelTexture uses a three-component, full-color texture and illustrates how to turn lighting off (by not specifying a Material). The third object shows a four-component texture with lighting on. The fourth PixelTexture illustrates the effect of setting the repeatS and repeatT fields to FALSE:
