jReality: a Java library for real-time interactive 3D graphics and audio
jReality is a Java based, open-source, full-featured 3D scene graph package designed for 3D visualization and specialized in mathematical visualization. It provides several backends, including a JOGL one for Java based OpenGL rendering. JReality is thread-safe, has a flexible shading model based on an attribute-inheritance mechanism in the scene graph, device-independent user interaction and support for true 3D audio (JACK). Furthermore, there are many support classes for transformations and geometry. It has a plugin system for assembling custom viewers, an active forum and a growing set of tutorial examples to help developers interested in using jReality to solve their Java 3D problems.

News
The latest release of jReality is ready. (We attempt to make monthly releases.)
Notable improvements include:
- The most bugs should be solved now and we moved jReality successfully from OpenGL 1.3 to OpenGL 2.
- Our new backend will be based on OpenGL 3.3. For first impressions follow these instructions.
Future improvements:
- We are planing to switch jReality form Svn to Git to facilitate the work of external developers.
Please report any issues on our forum
We updated the phpBB-forum to version 3.06.
Now there is a RSS-feed available for the forum.
Here you will find a short HowTo

The recently developed audio features of jReality were presented at the International Computer Music Conference ICMC 2009 in Montreal, Canada.
jReality will be presented at the ACM International Conference on Multimedia 2009, as part of the Open Source Software Competition.

The video about the Berlin Mathematical School is part of the DFG Video Portal, and shows jreality running in the Portal at TU Berlin, Mathematics Department. The portal is a 3-wall CAVE-like installation with passive stereo 3D and head-tracking.

The jbullet physics engine has been integrated into jReality. The project also contains collision sound synthesis, based on Jass.

Test drive this webstart demo now.
Highlights
- Experience mathematical constructs as physical objects! You can even through things at them (middle mouse button)!
- Includes real-time synthesized audio. This may require a fast computer to run smoothly. You can turn off audio, uncheck “sound” in the “Main Physics Controls” Panel on the left.
- Comes with the necessary 3rd party jars and an eclipse project file for easy configuration.

The jReality tutorials released in July have continued to be developed further. The current selection of topics covers most of the necessary topics for working with the jReality scene graph. Please continue to report suggestions or corrections to gunn at math.tu-berlin.de
Highlights
- A new User tutorial: An introduction to using ViewerApp
- An expanded and updated Developer tutorial: An introduction to programming with jReality
Each tutorial example now includes a link to run as a Java webstart!
We have started to implement a new plugin system which makes creating customized jReality applications easier than ever. See Stefans talk. about his plugin API.

jReality is part of the Exhibition Imaginary – mit den Augen der Mathematik.
The exhibition will visit many places in Germany during the Math year 2008.

We have implemented the jReality VR viewer. It allows loading 3D arbitrary data files but also includes a set of examples, several interesting mathematical surfaces as well as the Matheon buddy baer. The whole GUI for this application can be immersed into the 3D scene, so this application is also fully usable in immersive 3D environments (CAVEs).
