使用圖形硬體之容積視覺化平台

Abstract

Volume Rendering is an important scientic visualization method that is used widely in medical data, bioinformatic data, and scientic simulation results. In 2004, we started to develop volume rendering feature for our 3D VR Engine [12]. In this paper, we showed our work on creating this volume visualization platform, which integrated view-align slicing, pre-integration, multi-volumes rendering, time-varying volume rendering, and a graphics user interface for transfer function. Our platform met the needs for high quality volume rendering, multi-volumes, time-varying volume display, and had real-time adjustment for transfer function. Meanwhile, we maintained its extensibility and used graphics hardware functions when possible.
