Overview
The JOGL-Demos project contains Java programming language
demonstrations utilizing OpenGL through the JOGL API. Demonstrations exhibit
advanced functionality such as vertex and fragment programs, shadow maps and
hardware-accelerated offscreen rendering via pbuffers. Some of the demos were ported from
C or C++, in which case a link to the original sources is provided.
The demos below require Java Web Start,
which
is included in J2SE >= 1.5;
click the images to launch the demos. Where there are no hardware or
operating
system requirements listed, the demos run on any vendor's graphics card
and on any of Solaris/SPARC, Solaris/x86, Linux/x86, Windows/x86, and
Macintosh OS X 10.3.
It is now possible to deploy unsigned applets using JOGL with no
manual installation of any software on the end user's machine! Please
see the following test pages for more information:

The source code for these demonstrations is available
via GIT.

Grand Canyon Demo
|
|
Description
|
|
Requirements
|
|

Hardware Shadow
Mapping
|
|
Description
|
|
Requirements
|
|
Shadowing demo using projective
texture technique of hardware shadow maps.
Original source code by NVidia.

High Dynamic Range Rendering
|
|
Description
|
|
Requirements
|
|
High Dynamic Range rendering demo utilizing 16-bit-per-channel
floating-point pbuffers through NVidia, ATI or Apple extensions. Uses NVidia HILO or
Apple or ATI floating point cubemaps. Intermediate results are rendered to
floating-point pbuffers and tonemapped to 24-bit RGB before display. Original
source code supplied in NVidia's SDK. This demo
is known to work on Windows with suitable NVidia or ATI hardware, and on X11
platforms with suitable NVidia hardware (no floating-point pbuffer support is
available on X11 from ATI as of this writing). The demo should run properly on Mac
OS X soon pending some driver-level bug fixes.
