The nodes are typed, the main division being between Group and Leaf nodes. Structure built from nodes representing 3D models, lights, sounds, theīackground, the camera, and many other scene elements. Underlying graphics pipeline is hidden, replaced by a tree-like ģD uses a scene graph to organize and manage a 3D application. TIP: The FCS release of Version 1.3.2 will be available by the time you read this. It can beĭownloaded from, together with ample documentation and a long tutorial. The stable OpenGL version (1.3.1) in the rest of this book. Of the current "bug fix" release of Java 3D, Version 1.3.2. However, I've never noticed any difference when I'veįuture seems brightest for the OpenGL version, which is the main focus Where some users report that it's marginally faster than the OpenGL DirectX is controlled by Microsoft alone,Īnd the OpenGL Architecture Review Board (ARB) allows input from manyĭirect X Graphics version of Java 3D is only available for Windows, OpenGL is ported toĪ wide range of platforms and OSs, and DirectX is limited to PCs The two APIs are unrelated to their functionality. Since both are based on the same graphics pipeline architecture and Most technical areas, DirectX Graphics and OpenGL are almost equivalent The relative merits of DirectX Graphics and OpenGL. The debate about which version of Java 3D is better is a debate about The other DirectX APIs support 3D audio, networking, input device integration, multimedia, and installation management. It's part of DirectX, aĬollection of related gaming modules aimed at MS Windows ( ). Geometry in terms of vertices and pixels. Graphics supports a traditional graphics pipeline, describing all (build 7 and later), both versions are in a single download. Since they were offered as separate installers. To the 1.3.2 bug fix release, a programmer had to choose whether toĭownload the OpenGL version of Java 3D or the DirectX implementation

It's a low-level API based around a graphics pipeline for pixel and vertex manipulation. Writing 3D (and 2D) graphics applications across a wide range of For example, a rarely occurring bug with the J3DTimer class has been fixed.īy the time you read this, Version 1.3.2 will have been finalized (an FCS release will be available).Īre two Java 3D variants: one implemented on top of OpenGL, and the Is a Version 1.3.2, but it's a bug fix release under review as I write Sun Microsystems, and the most recent stable release is Version 1.3.1. Geometry, materials, lights, sounds, and more.

Java 3D API provides a collection of high-level constructs forĬreating, rendering, and manipulating a 3D scene graph composed of Then, I'll examine Java 3D's suitabilityįor games programming by considering the criticisms leveled against it. Summarize the main elements of Java 3D in this chapter, leaving programĮxamples aside for the moment.
