Is it possible to make a snapshot image (JPEG) from the current scene in a Java 3D program?

There is an entry in the j3d.org FAQ discussing how to capture still images from Java 3D: www.j3d.org/faq/capturing.html

Basically, once you have a BufferedImage containing the scene bits, you save them to disk as a JPEG using Java 2D. Please see the related FAQ item, "How can I take snapshots of Java components and save them into image files?", for specifics on saving JPEGs using Java 2D.
