In data visualization, characterizing local geometric properties of non-linear projection manifolds provides the user with valuable additional information that can in uence further steps in the data analysis. We take advantage of the smooth character of GTM projection manifold and analytically calculate its local directional curvatures. Curvature plots are useful for detecting regions where geo...

The programmability and texture support of consumer graphics accelerators have drawn a lot of attention from visualization researchers, resulting in some very important advances in interactive volume data visualization. For many applications, scientists can now perform routine data visualization and analysis tasks on their desktop PC with a consumer graphics card that was designed mainly for pl...

The use of fancy graphics can have a mesmerizing effect on simulation novices and, as such, may blind the user to the actual capabilities and valid usages. The visualization of simulations are distinct from other computer graphic media because they are a representation of an abstract of reality (the model) as opposed to a representation of reality. This extended abstract provides examples of vi...
