Adding 3D Sound
Three dimensional sound can add to the feeling of immersion in a virtual environment, but it generally isn't as important as lighting or 3D user interaction. As has been stated often in this book, spatial navigation in the real world is multisensory in nature. As with any spatial cue, lack of or improper use of aural cues will detract from the user's feeling of immersion.
Java 3D has a fairly sophisticated 3D Sound model that can be used to advantage in many situations. At present, the Java 3D Sound model is based on panning only. Panning is the gradual switching between speakers. When we develop our 3D shopping mall demonstration in Chapter 14, we will use the JMF Sound Player in conjunction with the Java 3D Sound classes.
