Summary of Work for Joint Research Interchanges with DARWIN Integrated Product Team 1998

摘要

The intent of Stanford University's SciVis group is to develop technologies that enabled comparative analysis and visualization techniques for simulated and experimental flow fields. These techniques would then be made available under the Joint Research Interchange for potential injection into the DARWIN Workspace Environment (DWE). Our current research effort focuses on finding a quantitative comparison of general vector fields based on topological features. Since the method relies on topological information, grid matching and vector alignment is not needed in the comparison. In addition, since only topology based information is stored and compared for each field, there is a significant compression of information that enables large databases to be quickly searched. This report briefly (1) describes current technologies in the area of comparison techniques, (2) describes the theory of our new method, and finally (3) summarizes a few of the results.
