A Software Model for Visualization of Time Dependent 3-D Computational Fluid Dynamics Results

摘要

We believe that the current generation of scientific visualization systems are inadequate for flexible, interactive, animated visualization of the largest time dependent numerical simulations. The current approaches are inherently too inflexible and/or too slow. To address this deficiency, we propose a new software model for time dependent 3-D visualization. The model introduces concepts to improve visualization of very large (many gigabyte) time-dependent numerical solutions. To provide direct user control over crucial time vs. space vs. flexibility trade-offs, the model includes a persistent object database of all scientific and visualization data including time and space metrics. The model provides a common framework for users and developers to understand visualization system requirements and capabilities. There are currently a number of efforts to incorporate the model into existing and new visualization systems.
