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/x86, Linux/x86, Windows/x86, and Macintosh OS X 10.5.

Applets using JOGL can be deployed without signing your own code and without manual installation of any software on the end user's machine:

• JOGL Applet Tests (next version)
• NApplet w/ AWT: Gears, Gears w/ JOAL
• NApplet w/ NEWT's Applet Runner:
  • Gears
  • Angeles
  • FBO Cubes
  • Cube
• JNLP Applet with Applet-Launcher fallback: Gears, Gears w/ JOAL
• Plain test page (next version)

Quick Version Info: Current [ NApplet, Application ], Next [ NApplet, Application ].

The source code for these demonstrations is available via GIT.

Gears Description Requirements Classic OpenGL demo. Original source code by Brian Paul; converted to Java by Ron Cemer and Sven Goethel. None

Grand Canyon Demo Description Requirements A flight simulator written in the Java programming language using the New I/O APIs and OpenGL to visualize a large terrain data set in real time. Related article, including source code, on the Swing Connection. None

Hardware Shadow Mapping Description Requirements Shadowing demo using projective texture technique of hardware shadow maps. Original source code by NVidia. Pbuffer support, ARB_shadow, ARB_depth_texture

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. One of GL_NV_float_buffer, GL_ATI_texture_float, or GL_APPLE_float_pixels; ARB_multitexture; ARB_vertex_program; ARB_fragment_program

Infinite Shadow Volumes Description Requirements Shadowing demo using geometric technique of infinite shadow volumes. Original source code by NVidia. None

JRefract Description Requirements Variant of NVidia's vtxprog_refract demo showcasing JOGL's hardware-accelerated Swing component. Original source code supplied in NVidia's SDK. If running on Java SE 6 (Mustang), try the fully OpenGL-accelerated version of this demo using the new Java2D/JOGL interoperability support! pbuffer support, ARB_vertex_program

Particle Engine Description Requirements Particle engine demo controlling a set of animated particles with a Swing UI. Contributed by Ben Chappell. None

TextRenderer Test Description Requirements A simple test of JOGL's new TextRenderer utility class, with text overlaid on the Gears demo. None

Flying Text Description Requirements A more advanced demo of the TextRenderer, showing animated and colored text with drop shadows. None

Custom Text Description Requirements A more advanced demo of the TextRenderer, showing the use of a custom RenderDelegate to achieve fancy Java 2D-based font effects. None

Text Flow Description Requirements Shows how to use the TextRenderer to draw dynamically flowing text in OpenGL. None

Text Cube Description Requirements Shows how to use the TextRenderer to draw 2D text in 3D. None

Vertex Program Warp Description Requirements Geometrical deformations performed on the graphics card using vertex programs. Original source code supplied in NVidia's SDK. ARB_vertex_program

Vertex Program Refract Description Requirements Real-time reflection and refraction with chromatic aberration using vertex and fragment programs. Original source code by NVidia. ARB_vertex_program and either ARB_fragment_program or NV_register_combiners

Water (Procedural Texture Physics) Description Requirements Runs a physics-based water simulation entirely on the graphics card using vertex programs, fragment programs and pbuffers. Original source code supplied in NVidia's SDK. Pbuffer support, ARB_vertex_program, ARB_fragment_program

XTrans Description Requirements Illustrates another use of the Java2D/JOGL interoperability bridge to provide OpenGL-accelerated animated transitions for unmodified Swing components. Requires Java SE 6 (Mustang) build 53 or later. Java SE 6 (Mustang) build 53 or later

Vertex Buffer Object Description Requirements Demonstrates high-throughput dynamic geometry using ARB_vertex_buffer_object extension. Original source code supplied in NVidia's SDK; ported both to Java/JOGL and ARB_vertex_buffer_object extension. ARB_vertex_buffer_object
