Abstract

Illustrative visualization aims to effectively communicate a specific information. In traditional illustration the choice of appropriate styles and rendering techniques is guided by the intention of the artist. For illustrative volume visualizations it is difficult to specify the mapping between the 3D data and the visual representation. We introduce a layer between data and visual appearance that allows the semantic specification of the visualization mapping. Our framework enables a linguistic formulation of rendering styles and techniques. A fuzzy logic rule base determines the constraints of the resulting interactive illustration. The fuzzy logic is automatically translated into a shader program and is evaluated directly on the GPU. The framework provides high quality illustrations that are guided by the specification of semantic illustration rules. The evaluation of the fuzzy logic on the GPU allows user-guided and view-dependent changes of the resulting illustrations. We show examples of semantics driven illustrative volume rendering at interactive frame rates.
