<h3><span style="font-weight: bold; text-decoration: underline;">Building
the 3D packages</span></h3>
<p><span style="text-decoration: underline;"><span
style="font-weight: bold;"></span></span><span
style="font-weight: bold; text-decoration: underline;"> </span></p>
<p>To
build the 3D packages, you must checkout the following three
CVS
repositories:<br>
</p>
<ul>
<li><a href="http://j3d-core.dev.java.net/">j3d-core</a></li>
<li><a href="http://j3d-core-utils.dev.java.net/">j3d-core-utils</a></li>
<li><a href="http://vecmath.dev.java.net/">vecmath</a></li>
</ul>
<p>These three top-level directories must be named exactly as
shown above and they must be sibling directories. To ensure this, run
the cvs checkout command for each of the respositories from the same
parent
directory. For example:<br>
</p>
<ul>
<code>cd <cvs-root-dir></code><br>
<code>cvs checkout vecmath</code><br>
<code>cvs checkout j3d-core</code><br>
<code>cvs checkout j3d-core-utils</code>
</ul>
<p>NOTE: you must first build the javax.vecmath package before building
the javax.media.j3d and com.sun.j3d.* packages. See the <a
href="../vecmath/README-build.html">README-build.html</a> file in the
"vecmath" directory for instructions.<br>
</p>
<h3><span style="font-weight: bold; text-decoration: underline;"></span><span
style="text-decoration: underline;">System Requirements</span></h3>
<p><span style="font-weight: bold; text-decoration: underline;"></span></p>
<p><span style="font-weight: bold; text-decoration: underline;"></span>The
following operating environments have been tested:<br>
</p>
<ul>
<li>Solaris: Sparc (Ultra60 or better) running Solaris 9 with Forte C
compiler version 6.2 or GNU gcc version 3.3.2</li>
<li>Linux: i386/i586 running SuSE 9 or RedHat 9.0</li>
<li>Windows: Windows/XP with Microsoft Visual C++ 6.0 or the gcc that
comes with <a href="http://www.mingw.org">MinGW version 3.1.0-1</a>
(Windows 2000 should work, but is untested)<br>
</li>
</ul>
<p> The following software must be installed:<br>
</p>
<ul>
<li><a href="http://java.sun.com/j2se">JDK 1.5.0 </a><br>
</li>
<li><a href="http://jakarta.apache.org/ant">Apache Ant 1.6.1</a><br>
</li>
<li>C Compiler (Either one of the following depending on the platform)<br>
</li>
<ul>
<li>Solaris:<br>
</li>
<ul>
<li>Sun ONE Studio 8 (formerly Forte Tools)'s Compiler or GNU
Compiler Collection, <a href="http://gcc.gnu.org">GCC version 3.3.2</a><br>
</li>
</ul>
<li>Linux:<br>
</li>
<ul>
<li>GNU Compiler Collection, <a href="http://gcc.gnu.org">GCC
version 3.2.2</a><br>
</li>
</ul>
<li>Windows<br>
</li>
<ul>
<li>Microsoft Visual C++ 6.0 or later or GNU Compiler
Collection, GCC version 3.2.3 that comes with<a
href="http://www.mingw.org"> MinGW version 3.1.0-1</a><span

</ul>
</ul>
</ul>
<h3><span style="font-weight: bold; text-decoration: underline;">Building the 3D packages</span></h3>
<p><span style="font-weight: bold; text-decoration: underline;"></span><span
style="font-weight: bold; text-decoration: underline;"></span>Before
you start building, your PATH must include the
following directories:
</p>
<ul>
<li><ant-root-dir>/bin<br>
</li>
<li><jdk-root-dir>/bin<br>
</li>
<li><compiler-root-dir>/bin<br>
</li>
</ul>
<p>The default target, jar-opt, creates an optimized jar files
and native libraries.
</p>
<p>On Amd64 platform an OutOfMemoryError can be seen. In this case set
the environment variable ANT_OPTS to -Xmx256m.<br>
</p>
<p>Steps:
</p>
<ul>
<code> cd <cvs-root-dir>/j3d-core<br>
ant</code>
</ul>
<p>The above steps build both the Java and native code for
javax.media.j3d and com.sun.j3d.*
packages.
</p>
<p>The build will be placed in j3d-core/build/<platform>/opt
where <platform> is determined from the <code>ant
echo</code> command:
</p>
<ul>
<code>ant echo</code>
</ul>
To see other targets that are available, type "ant
-projecthelp". Note that ant must be run from the top-level
directory.
<p>The default compiler for native code compilation is set to "gcc".
This
value is set in the <a href="build.properties">build.properties</a>
file located
in the j3d-core directory. The compiler property is "build.comp".<br>
</p>
<p>On a Solaris platform with Forte compiler installed,
build.comp
can be set to "forte". On a Windows platform installed Visual C++,
build.properties
can be set to "vc".<br>
</p>
<p>NOTE: For Windows platform only, the property "build.rend" in
build.properties can be modified to use "d3d" (Direct3D API for
rendering) besides the default value "ogl".<br>
</p>
<p>NOTE: You can also modify the properties via command-line options to
ant,
for example, "ant -Dbuild.comp=vc"<br>
</p>

the 3D examples</span></h3>
<p>Please refer to <a
href="../j3d-examples/README-build.html">README-build.html</a> in
j3d-examples for
details
on building and running the 3D example programs.<br>
