Let's reexamine the example code from last month's Example 3 to learn more about how things are situated in three dimensional space using Java 3D.Īnd finally, it's important to note that the coordinate system is aligned with your view into it. One reader in particular asked why, when he modified the transform so the cube's z coordinate was positive, he could no longer see the cube. I received several reader questions about the placement of the 3D objects in last month's examples. We'll also discuss the interplay between Java 3D and VRML, review the performance characteristics of Java 3D, and set the stage for next month's look at Java OpenGL bindings. This month we'll conclude our introduction by delving into loaders for larger scene graphs and giving our worlds behaviors and interactivity. Last month we began our exploration of Java 3D with static content and small scenes. Beyond the basics that every 3D API must provide, what does Java 3D have going for it? This is fact, but not certainty, as Sun faces heavy competition from other technologies, especially OpenGL. Java 3D has the potential to allow Java programmers of all sorts to include vibrant 3D content in their applets and applications.
