<title>The Java 3D API Core</title>
</head>
<body>
<p>This project contains the source code
for the core Java 3D API
package, <code>javax.media.j3d</code>.<br>
</p>
<p>Related projects include: <a href="http://vecmath.dev.java.net/">vecmath</a>
(the 3D vector math package), <a
href="http://j3d-core-utils.dev.java.net/">j3d-core-utils</a> (the
Java 3D core utilities), and <a
href="http://j3d-examples.dev.java.net/">j3d-examples</a> (the
Java 3D
example programs). The vecmath and j3d-core-utils projects are required
to build j3d-core. Refer to the <a href="build-instr.html">download
and build
instructions</a> for information on downloading and building j3d-core.</p>
<h3>License</h3>
<p>The source code for the core Java 3D API reference
implementation
is licensed under the <a href="http://java3d.dev.java.net/jrl.html">Java
Research License (JRL)</a> for non-commercial use. The JRL allows users
to download, build, and modify the source code in the
j3d-core project for research use, subject to the terms of the license.
</p>
<p>Java 3D is also licensed for commercial use under a new
no-fee <a href="http://java3d.dev.java.net/jdl-java3d.pdf">Java
Distribution License (JDL)</a>. The JDL
allows commercial use of Java 3D with or without modification, as
long as compatibility with the entire API Specification is maintained.
This includes passing the TCK tests for Java 3D, and retaining the
javax namespace as defined by the JCP.
</p>
<p>
The API specification will continue to evolve as part of the Java
Community Process (JCP). We welcome community participation, and
encourage developers to contribute both bug fixes and new
implementation code to the API. The combination of the JRL and the JDL
was chosen to facilitate this, while ensuring the integrity and
compatibility of the API.<br>
</p>
<h3>Downloads</h3>
<p>Three types of binary builds are available in the <a
href="../servlets/ProjectDocumentList">Documents
& Files</a>
section of this project on java.net: Release (or FCS) builds;
Experimental (early access) builds; and Daily/Weekly builds. The latest
release build of Java 3D v1.3.1 is available. A fairly stable
experimental build, labeled as Java 3D v 1.3.2-build3 is now
available. We will set up daily or weekly builds in the near future.<br>
</p>
<h3>How to Contribute</h3>
<p>We invite developers to contribute to Java 3D. Please refer to
the
<a href="http://java3d.dev.java.net/contribute.html">Contributing to
Java 3D</a> section in the parent java3d project to learn
how to contribute to this project or any other Java 3D-related
project.</p>
<h3><a name="Project_Highlights"></a>Project Highlights</h3>
<p><b>Release project Source code</b> </p>
<p>The current, experimental fork of the of the Java 3D source
code is an early access of version 1.3.2. It is
available for download from the CVS repository of this project.<br>
</p>
<p>This source release differs from the the current 1.3.1 release in
the following
ways:<br>
</p>
<ol>
<li>The <code>com.sun.j3d.*</code> packages have been split out into
their own project (<a href="http://j3d-core-utils.dev.java.net/">j3d-core-utils</a>).</li>
<li>Apache Ant is now used to build Java 3D<br>
</li>
<li>The Headspace AudioEngine has been removed. The JavaSound
AudioEngine, which is not fully functional, is now the only available
AudioDevice<br>
</li>
<li>The internal documentation has been cleaned up for
public
consumption (although <span style="font-weight: bold;">much </span>work
is needed on the actual content)<br>
</li>
<li>Some minor bug fixes have been incorporated<br>
</li>
</ol>
<p>The reason the Headspace AudioEngine was removed is that we do not
have
the rights to ship the source code for the native Headspace sound
mixer. Our plan
going forward is to implement an AudioEngine using <a
href="http://joal.dev.java.net/">JOAL</a>.</p>
<p><span style="font-weight: bold;">Java 3D 1.3.x bug fixes</span><br>
</p>
<p>We will work with the community to address bugs identified in
Java 3D
1.3.1, and will release new versions of Java 3D 1.3.x as
needed.
Bug fixes will be immediately available in the CVS source, or from the
weekly builds on this site. We will release official 1.3.x versions no
more often than twice a year.<br>
</p>
<p><span style="font-weight: bold;">Java 3D 1.4</span><br>
</p>
<p>We will file a new JSR (or revive the existing <a
href="http://jcp.org/en/jsr/detail?id=189">JSR-189</a>) under the Java
Community Process (JCP) shortly, and form an Expert Group of community
members to
design and implement the next version of the Java 3D API. We
envision 1.4
including features such as programmable shaders. Our goal is to
minimize large scale changes to the system in order to deliver 1.4 as
quickly as possible. This initial direction could be changed by the
Expert Group.<br>
</p>
<p><span style="font-weight: bold;">Java 3D 1.5/2.0</span><br>
</p>
<p>The scope of this release will be driven by the JSR Expert Group.
Our initial
thoughts are that this work will include large scale changes to support
features such as extensibility and pluggable renderers.<br>
</p>
<h3><a name="Project_Suggestions"></a>Project Suggestions</h3>
<p>Here are some project ideas for the j3d-core project. Please see the
<a href="http://j3d-core-utils.dev.java.net/#Project_Suggestions">Project
Suggestions</a> in the <a href="http://j3d-core-utils.dev.java.net/">j3d-core-utils</a>
project for more ideas.</p>
<ul>
<li>DirectX build environment for MinGW (using gcc)<br>
</li>
<li>DirectX 9 port</li>
</ul>
<h3>Examples</h3>
<p>The <a href="http://j3d-examples.dev.java.net/">j3d-examples</a>
project includes a set of simple example programs. The <a
href="http://java.sun.com/products/java-media/3D/flythrough.html">Java 3D
Fly Through v 2.0 Beta</a> sample application shows you how to take
advantage of the capabilities of Java 3D technology. You can
download
the source code via <a href="http://java3d.netbeans.org">http://java3d.netbeans.org</a>.<br>
</p>
<h3>Feedback and Discussion<br>
</h3>
<p>We have created two Java 3D mailing lists in the parent <a
href="http://java3d.dev.java.net/">java3d</a> project: <a
href="mailto:announce@java3d.dev.java.net">announce@java3d.dev.java.net</a>
and <a href="mailto:interest@java3d.dev.java.net">interest@java3d.dev.java.net</a>.
<a href="http://java3d.dev.java.net/servlets/ProjectMailingListList">Click
here to subscribe</a> to either of these lists. The annouce list is a
low-volume moderated mailing list for announcing Java 3D-related
news
and information. The interest list is an open mailing list for
discussing all aspects of Java 3D, the reference implementation
for the
Java 3D core, vecmath, utilities, example programs, etc.</p>
<p>For those who prefer a forum to a mailing list, we have created the
<a href="https://java3d.dev.java.net/servlets/ProjectForumView">Java 3D
forum</a>, hosted as part of the JavaDesktop Community. Messages
posted on the forum are cross-posted to <a
href="mailto:interest@java3d.dev.java.net">interest@java3d.dev.java.net</a>
and vice-versa.<br>
</p>
<p>Finally, each sub-project has its own cvs and issues mailing
lists. <a href="servlets/ProjectMailingListList">Click here to
subscribe</a> to either of these lists. The <a
href="mailto:cvs@j3d-core.dev.java.net">cvs@j3d-core.dev.java.net</a>
list is for automated CVS change messages and discussion of those
changes. The <a href="mailto:issues@j3d-core.dev.java.net">issues@j3d-core.dev.java.net</a>
list is for automated issue tracking.<br>
