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.
