没入型ボリュームレンダリング向け画像重畳技術 Hardware-Assisted Image Composition Technique for Immersive Volume Rendering
In recent years, PC Clusters enhanced by high-performance consumer graphics cards have received increasing attention as an effective solution for real-time, high-resolution volume rendering of large data sets. However, the image composition process becomes a bottleneck when using traditional software approaches. Although several efficient algorithms have been proposed, their performance depends directly on the quantity of active pixels. Thus, accentuated performance degradation is expected during an immersive visualization where a screen is filled by active pixels. In this report, we present and evaluate a graphics cluster in its minimal configuration with a commercially available hardware image compositor manufactured by Mitsubishi Precision as a commodity hardware solution for the performance demands of immersive visualization as well as high-resolution visualization.
