Visualization Techniques for Time-Varying Volume Data


Our ability to study and understand complex, transient phenomena is critical to solving many scientific and engineering problems. This paper addresses the issues in storage space, I/O, and rendering for visualizing time-varying volume data. A suite of effective techniques, including encoding, parallel rendering, and runtime visualization techniques are discussed. In particular, we introduce a new hardware-assisted technique coupled with a compression scheme based on Discrete Cosine Transform which allows interactive exploration in both spatial and temporal domains of the data using a PC with a commodity graphics card.
