Abstract:
Emphasis and focussing techniques are designed to consider the importance
of objects within the rendering process. Such techniques are essential in
medical education and therapy planning systems. Non-photorealistic rendering
techniques, such as silhouette lines, are essential in this context as they convey
the shape of objects without occluding large areas. We discuss emphasis and focussing
by means of NPR in medical visualizations. We introduce techniques
which emphasize a selected object in 2d as well as 3d visualizations.
