This paper presents a mathematical data model for scientific visualization based on the mathematics of fiber bundles. The findings of previous works are extended to the case of piecewise field representations (associated with grid-based data representations), and a general mathematical model for piecewise representations of fields on irregular grids is(More)
Good morning, and welcome to the panel session o n effective software systems for scientific data visualization. Before we get started, we want to make just a couple o f announcements. The entire proceedings will be taped. Therefore, when you come up during the interactive portion o f the session to ask questions, make sure you come to the mike s in the(More)
The author describes NCSA's approach to the development of visualization tools for scientists at remote locations as well as those with complex special requirements. The Rivers (Research on Interactive Visual Environments) Project is an interesting and potentially important attempt to extend high-end visualization to the interactive steering of(More)
1. Abstract We propose a fictitious domain method for topology optimization in which the boundary of the optimal design is identified by a level set of the topological derivative field of the objective function that satisfies a given resource constraint. The response analysis employs a smooth and consistent projection of the geometry onto the fictitious(More)
Dataaow computing model is a simple yet powerful mechanism for constructing distributed visualization applications that transform numerical data into images. However, current data-ow visualization systems have serious memory eeciency problems when processing large data sets. In this thesis, we have identiied a class of visualization algorithms that require(More)
