Shadows with a Message

摘要

Providing textual annotations for 3D visualizations poses a number of interesting challenges: It is difficult to find a suitable position for the text such that the image-text co-referential connection is obvious for the user and, at the same time, the text does not occlude the 3D model. In this paper we address this problem by using cast shadows as text containers. This approach leverages the existing benefits of the shadow metaphor in visualizations. Problems which arise in this context are also discussed.
