While data with uncertainties arises in many scientific domains and engineering applications, the visualization of such data remains challenging as uncertainty information must be included in an accessible and compre- hensible manner.In this paper we present pulsating uncertainties as a novel way to highlight uncertainties by animated two-dimensional transfer functions (2DTF) for uncertain scalar data sets.

It allows for a flexible classification by 2DTFs and an effective and pre-attentive highlighting of uncertainty by animating the 2DTFs while enabling users to simultaneously explore the 3D scene.In addition, we present the isosurface variability widget to highlight the variability of isosurfaces for data with uncertainty.We demonstrate the characteristics of the new approach by experiments using climate simulation and medical data.» weiterlesen» einklappen
