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.
