The "Virtual Universe" is a realistic, three-dimensional cyberspace and virtual reality simulation. People can meet, interact with each other, build houses and whole worlds, simulate workflows, test designs, and much more. Due to its extensive programming interface, this virtual reality environment can be used for scientific and engineering tasks such as simulation and visualization applications. It also includes a terrain generator for virtual landscapes and the Java XTools, an extensive package that contains several enhancements and improvements for Java3D and Swing.
