Designed for non-expert scientists considering to use VR, Aura presents an easy-to-understand C++ API that extends basic available low-level graphics facilities like OpenGL or Direct3D with scene graph management paradigms and a VR programming framework. In short, Aura deals with the following features:

Currently supported platforms are:

Aura can be extended with VIRPI and CAVEStudy to provide a fully integrated interactive visualization and measuring environment for arbitrary legacy simulation program.

Future plans for Aura include fixing existing bugs, adding new image/model formats, extending the VR framework, and providing bounding-box algorithms to do clipping and preliminary collision detection. Most importantly, Aura will be targeted at PC clusters that drive a tiled display wall, providing the same API for the programmer, but fully using distributed rendering on the cluster.
