Introduction to Java 3D API (1)

• Java 3D API is a programming interface for
  writing 3D applications and applets.
• Goals
• Provide a rich set of features for creating
  interesting 3D worlds
• Provide a high-level object-oriented
  programming paradigm
• Provide support for runtime loaders.

Introduction to Java 3D API (2)

• Features of Java 3D API
• Object-oriented Programming Paradigm
• Scene graph based programming model (DAG)
• Three different rendering modes immediate
  mode, retained mode, and compiled-retained mode.
• Add behavior to scene graph nodes

Introduction to Java 3D API (3)

• Pro and Cons
• Pros
• High-level, object-oriented view of 3D
  graphics.
• Optimized for speed where possible
• Growing number of 3D loaders
• Support a number of input devices
• Cons
• Less portable
• No low-level access to rendering process
• Java 3D is heavyweight

Conclusion

• Java 3D graphics is more realistic than Java
• Easy to develop and supports more feature than
  Java
• Java is more portable now than Java 3D
• Java costs less
