JOGL Demos
Java™ Binding for the OpenGL® API (JSR-231)

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. Most 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 1.4.2; 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.

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
$Launch JRefract demo$	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

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
