J3D-RenderingAttributesStructureUpdateThread Note that unlike nondaemon threads, daemon threads do not have to exit their RunnableРІР‚в„ўs run method for the JVM to exit. The priority of the parent ThreadGroup (Java 3D) cannot be exceeded. The priority must fall between Thread.MAX_PRIORITY and Thread.MIN_PRIORITY. The Java 3D threads have the default thread priority of 5, although this can be controlled using the tJ3DThreadPriority method. The two ThreadGroups, РІР‚СљmainРІР‚Сњ and РІР‚СљJava 3D,РІР‚Сњ are subgroups of the top-level РІР‚СљsystemРІР‚Сњ ThreadGroup. 18.2 Threads running a Java 3D applicationР”Р„s you can see from tables 18.1 through 18.3, a typical Java 3D application contains many threads, some concerned with system behavior, some running the GUI event processing, and some (13) controlling the Java 3D runtime environment. By explicitly activating the threads in the system, the 1.2 API has removed the free-running threads (behaviors and collision detection) that caused 100 percent CPU utilization in Java 3D 1.1. The collision detection thread was removed in 1.2, and collision detection is carried out by the new TimerThread functionality. Version 1.2 moved to a message-based architecture and took tighter control of the various worker threads created by the API implementation.

About 70 percent of the Java code was rewritten between these two versions! The Java 3D 1.1 architecture was fairly simplistic and could be considered a proof-of-concept implementation of the API. The implementation of the Java 3D API has undergone considerable revision between the 1.1 and 1.2 versions of the API. The version described here is Java 3D 1.2 running on the Win32 platform. SunРІР‚в„ўs Java 3D internal implementation details are all subject to change at any time. This chapter gives you some clues for implementing your own 3D graphics API in Java. In this chapter we gallop through some of the implementation details behind the Java 3D API gaining insight into getting the most from Java 3D and maximizing the performance of your applications. Interested learners are highly encouraged to do their own implementations from scratch, however.Java 3D Programming.Chapter 18 CHAPTER 18 Java 3D system architectureР”РЋ8.2 Threads running a Java 3D applicationР”В«y now I hope you are curious to know how Java 3D achieves what it does. This is especially useful in a live workshop, preventing students from falling behind. This way, if a student gets stuck on one lesson, they can experiment with another lesson by starting at a partial implementation of the renderer ready to go. Furthermore, students can build off an existing base by using the tagged commits that represent the state of the project just prior to beginning a new project. Students can follow along with an implementation, as each project is completed in its own commit.

The full source for multiple implementations of the renderer is available, with one commit per lesson. Students learn one foundational concept in each lesson, then implement that concept in their very own 3D renderer.

The workshop is laid out a series of lessons, each with a corresponding project. The workshop also lets me answer questions in person and help move students along the coursework in a timely fashion, but even without my presence, the material should be useful to a wider audience.

In the two-day workshop, I go through the fundamentals of 3D graphics, with an emphasis on foundational knowledge and hands-on experimentation. These is the course guide for a workshop I'm holding at Bradfield School of Computer Science.
