Multi-level topology for flow visualization

The technique for visualizing topological information in fluid flows is wel l known. However, when the technique is used in complex and information-ric h data sets, the result will be a cluttered image which is difficult to int erpret. This paper presents a technique for the visualization of multi-leve l topology in flow data sets. It provides the user with a mechanism to visu alize the topology without excessive cluttering while maintaining the globa l structure of the flow. (C) 2000 Elsevier Science Ltd. All rights reserved .
