public class ImageComponent3D
extends ImageComponent

This class defines a 3D image component. This is used for texture images. Prior to Java 3D 1.2, only BufferedImage objects could be used as the input to an ImageComponent3D object. As of Java 3D 1.2, an ImageComponent3D accepts an array of arbitrary RenderedImage objects (BufferedImage is an implementation of the RenderedImage interface). The methods that set/get a BufferedImage object are left in for compatibility. The new methods that set/get a RenderedImage are a superset of the old methods. In particular, the two set methods in the following example are equivalent:

BufferedImage bi;
RenderedImage ri = bi;
ImageComponent3D ic;


// Set image 0 to the specified BufferedImage
ic.set(0, bi);


// Set image 0 to the specified RenderedImage
ic.set(0, ri);
