Real-Time Volume Rendering of FCC Datasets Using Box-Splines on the Mobile Platforms

Visualizing volumetric datasets using real-time volume rendering technique involves a large number of interpolation operations that are computationally expensive. This situation used to restrict real-time volume rendering methods to be used only on high-end graphics workstations or special-purpose hardware. This paper presented a real-time direct volume rendering (DVR) implementation of face centered cubic (FCC) datasets with box-spline interpolation on mobile devices. The latest version of OpenGL ES (Open Graphics Library for Embedded System) (3.0) is used for implementation to leverage cutting-edge 3D graphics technology, and it shows interactive performance (2.40 frame per second (FPS)) for moderate-sized volume datasets (64×64×64).
