Scientific Visualization

We continued the cooperation with the GOCAD Consortium on visualization and modeling for geosciences. We developped a new method for simulating fault networks [12] , and conducted a user study to evaluate different techniques for visualizing geospatial uncertainties [17] .

We developped new techniques to visualize the structure of smooth scalar fields (convection or diffusion phenomena for instance). To address this issue, we developed a filter that produces a derived scalar field where successive iso-values give thinner representations of the structure of the original data. Figure 9 shows that compared with traditional volume rendering on a temperature scalar field (left) we are able to display more sharp and focused details of the plume (right) using the derived scalar field in the opacity transfer function.
