Perceptually Linear Parameter Variations
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Most visual analysis tasks require interactive adjustment of parameter values. In general, a linear variation of a parameter, using for instance a GUI slider, changes the visual result in a perceptually non-linear way. ...
Advected Tangent Curves: A General Scheme for Characteristic Curves of Flow Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We present the first general scheme to describe all four types of characteristic curves of flow fields - stream, path, streak, and time lines - as tangent curves of a derived vector field. Thus, all these lines can be ...
Interactive Rendering of Materials and Biological Structures on Atomic and Nanoscopic Scale
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The properties of both inorganic and organic materials and the function of biological structures can often only be understood by analyzing them simultaneously on atomic and nanoscopic, if not mesoscopic, scale. Here, the ...
Probabilistic Local Features in Uncertain Vector Fields with Spatial Correlation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this paper methods for extraction of local features in crisp vector fields are extended to uncertain fields. While in a crisp field local features are either present or absent at some location, in an uncertain field ...
