<H1>Jogl Demos - Documentation</H1>
<P>
This workspace contains the source code to demos for the Jogl
package. To build the demos:
<UL>
<LI> Check out and build the Jogl sources from <a href =
"http://kenai.com/projects/jogl/">http://kenai.com/projects/jogl/</a>; note that
these sources must go into a sibling directory to the jogl-demos
directory
<LI> Unset your CLASSPATH environment variable
<LI> cd into the "make" subdirectory of the jogl-demos workspace and
type "ant" (Ant can be obtained from <a href =
"http://ant.apache.org/">http://ant.apache.org/</a>
</UL>
To run the demos:
<UL>
<LI> Add the built jars to your CLASSPATH (jogl-demos.jar,
jogl-demos-util.jar, jogl-demos-data.jar)
<LI> Run one of the demos from the command line: e.g. <CODE>java
demos.gears.Gears</CODE> (Note: the current working directory is not
important)
</UL>
</P>
<H1>Hardware and Software Requirements</H1>
<P>
The demos currently have the following hardware and software
requirements:

<UL>
<LI> Alt + left click and drag: rotate camera about focal point
<LI> Alt + right click and drag: translate camera parallel to image plane
<LI> Alt + left + right click and drag: zoom camera in/out
<LI> Click and drag on the faces of the manipulators (look for the
yellow highlight of the faces upon mouse over) to translate the
manipulator parallel to that face. Use the handles outside the boxes
to rotate, and the handles at the corners of the boxes to scale.
<LI> Escape key or 'q' quits.
<LI> Space bar cycles through view options. Shadowed view; view from
light source; unshadowed view.
<LI> 'v' recenters camera on object
