<h2>
<font size=+1>The Features Of GL4Java</font></h2></center>
<ul>
<li>
Open Standard in the meaning of the GNU community.</li>
<ul>
<br>GL4Java is licensed under the <a href="http://www.gnu.org/copyleft/lgpl.html">´GNU
Library General Public License (LGPL)´ !</a>
<br>People can use it freely and can contribute code and ideas into this
living project.
<br>The API, of course, should being left stable. Changes should not affect
the current usage
<br>and should made compatible.
<p>Because the API and its implementation is free,
<br>there is no reason of being afraid that GL4Java will stop existing.
<br>The worst case is, that you must maintain GL4Java by yourself, if nobody
other does.
<br>But you are allowed to do so and everything you need is freely avaiable
!
<br> </ul>
<li>
It is avaiable for different OS / architectures.</li>
<ul>
<br>GL4Java can be seen as an Java extension, which has a native and a
java part.
<br>The native part is prepared for:
<ul>
<ul>
<li>
Unices</li>
<ul>
<li>
GNU/Linux + XFree86 3.Y.Z - 4.Y.Z</li>
<li>
Solaris</li>
<li>
Irix</li>
<li>
...</li>
</ul>
<li>
Windows 9x-NT</li>
<li>
Macintosh OS 9.Y.Z</li>
</ul>
</ul>
<p><br>The number of precompiled libraries for the different OS is
growing.
<br>Currently the most Unices, Windows and Macintosh is supported with
precompiled libs.
<br> </ul>
<li>
GL4Java Applets can run with Netscape (Unices+Windows) and with MS-IE (Windows)</li>
</ul>
<ul>
<li>
Can be installed via the WWW with a browser and the Installer-Applet.</li>
</ul>
The Installer-Applet can be used for a local installation also.
<ul>
<li>
Supports Java with a complete OpenGL 1.2 and GLU native library mapping.</li>
<ul>
<br>Any modifications and extensions to the OpenGL library will be followed.
<p>Uses true hardware accelerated (if supported by the OS) for AWT-Canvas
components,
<br>and currently offscreen rendered (may be hardware accelerated) Swing
components.
<br> </ul>
<li>
Supports a Java written <b><i><a href="http://reality.sgi.com/opengl/glut3/glut3.html">glut</a></i></b>implementation
(subset), included the glut-fonts.</li>
<ul> </ul>
<li>
Offers convinient classes and functions to:</li>
<ul>
<li>
Access OpenGL/GLU with a C like API.</li>
<li>
Bind the OpenGL context to the native Java window, or to an offscreen Image.</li>
<li>
Base classes to provide the user with basic Canvas features for still and
animation rendering, like <b><i><a href="http://reality.sgi.com/opengl/glut3/glut3.html">glut</a></i></b>.</li>
<ul>
<li>
Complete event handling for window refresh, etc.</li>
<li>
OpenGL context creation and binding</li>
<li>
Multi-Threading handling for animation</li>
<li>
Texture loading / saving in different formats: TGA, PNG, JPG, ...</li>
<li>
Applet integration and test classes</li>
<li>
Creating snapshots and displaying images</li>
<li>
...</li>
</ul>
</ul>
</ul>
