Abstract
| |
In this paper, we introduce a novel framework for the compositing of interactively rendered 3D layers
tailored to the needs of scientific illustration. Currently, traditional scientific illustrations are produced
in a series of composition stages, combining different pictorial elements using 2D digital layering. Our
approach extends the layer metaphor into 3D without giving up the advantages of 2D methods. The
new compositing approach allows for effects such as selective transparency, occlusion overrides, and
soft depth buffering. Furthermore, we show how common manipulation techniques such as masking
can be integrated into this concept. These tools behave just like in 2D, but their influence extends
beyond a single viewpoint. Since the presented approach makes no assumptions about the underlying
rendering algorithms, layers can be generated based on polygonal geometry, volumetric data, pointbased
representations, or others. Our implementation exploits current graphics hardware and permits
real-time interaction and rendering.
