Game Development Engines as an Ideal Platform for Exploring 3D Virtual Reality Based Visualizations Constructed from Computed Tomography Data

We demonstrate software to allow a user to explore an industrial computed tomography (CT) dataset using the Oculus Rift virtual reality goggles and a video game engine. We present many examples showing aspects of the data visualization and discuss the techniques used to achieve “presence” and “immersion” – users sense that they are in a world exploring an object. Most scientific visualization software today falls short of this goal due to the complexity and size of the data being analyzed. Individuals wishing to go beyond capabilities integrated into visualization software should consider using video game engines to facilitate analysis of their data.
