Abstract

For a better visualization and understanding of volumetric data, combinations of surface and volume rendering can be used. Since, the rendering techniques used for polygon surfaces and volumes are different, the combination is not trivial. The presented methodology enhances the state-of-the-art techniques Maximum Intensity Projection (MIP), Direct Volume Rendering (DVR) and Maximum Intensity Difference Accumulation (MIDA) with methods to render surfaces, by buffering the positions, normals and colors of the polygon models, and utilizing them in the ray marching process. The methods have been implemented in the AngioVis Toolbox as a plugin.
