COP3252Advanced Java Programming

• 27-Mar-08
• Lecture Set 19
• Java3D, JMF

2
Java3D

• Addition to Java for displaying three-dimensional
  graphics
• Provides a simple interface and is quite rich in
  capabilities
• Builds on existing DirectX and OpenGL technology
  --- so, programs are decently fast
• Can incorporate objects from 3D modeling packages
  like TrueSpace and VRML models.

3
Installing/Running Java 3D

• In addition to the J2SE JDK, you must also
  install the Java 3D extension
• Latest version 1.5.1
• Available here http//java.sun.com/javase/techno
  logies/desktop/java3d/

4
Creating a basic 3D program

• Create a virtual universe to contain your scene.
• Create a data structure to contain a group of
  objects.
• Add an object to the group
• Position the viewer so that they are looking at
  the object
• Add the group of objects to the universe
• See Hello3d.java for example

5
Adding light ( making it actually look 3d!)

• See Ball.java

6
More Information

• Java3D can be very complicated .
• Look here http//www.java3d.org/ (where these
  notes were pulled from)
• and here https//java3d.dev.java.net/

7
The Java Media Framework

• Allows programmers to create Java applications
  that can play, edit, stream and capture many
  popular media types.
• Some supported types
• .avi (Microsoft Audio/Video Interleave)
• .swf (Macromedia Flash 2 Movies)
• .spl (Future Splash)
• .mp3 (MPED Layer 3 Audio)
• .mid, .midi, .rmi (Musical Intrument Digital
  Interface)
• .mpeg, .mpg (MPEG-1 Videos)
• .mov (QuickTime)
• .au (Sun Audio File)
• .aif, .aiff (Macintosh AIFF file format)

The Java Media Framework

• Like with Java3D, the JMF is not part of the J2SE
  JDK it is a separate extension.
• Find it at http//java.sun.com/products/java-med

Simple Media Player

• See MediaPanel.java
• And MediaTest.java
