Applying Information Visualization Techniques to Visual Debugging
… but all are lacking in a key area: information visualization. Applying information visualization techniques such as zooming, focus and context, or graphical representation of numeric data may enhance the visual debugging experience. To this end, drawing data structures as graphs is potentially a …

The evaluation of turbulence models using tensor visualization techniques
A new method of representing a second order tensor, the tensor glyph, is used to present the Reynolds stresses found in turbulent flow. Various glyph types discussed in the literature are analyzed, and a glyph suitable for the Reynolds stress tensor is developed. This glyph is constructed so that …

Visualization of scalar velocity fields over one- and two-dimensional structures
Visualization techniques for representing scalar velocity fields over one- and two dimensional vibrating structures are investigated. High spatial density velocity fields are measured over a vibrating beam and a vibrating plate by a scanning laser velocimeter. The velocity measurements are assumed …
