java.lang.Objectorg.j3d.aviatrix3d.SceneGraphObject
org.j3d.aviatrix3d.NodeComponent
org.j3d.aviatrix3d.TextureUnit
Describes a texture stage and its associated texture and attributes.
The external data passed to the ComponentRenderable calls shall be an
Integer
instance that represents the GL texture unit of the
this instance is working with. If the value is -1, then only a single
texture is being used, so the class does not need to make use of the
glActiveTexture()
call.
