| Title |
Expressive illumination of foliage based on implicit surfaces |
| Abstract |
This paper presents an approach for vivid representations of foliage based on
implicit surfaces. It approximates the complex lighting interaction within the foliage
and enables a clear illustration of the general shape and the local density of
the foliage, thus supporting the three-dimensional depth cue of the viewer. Due
to its straightforward implementation as a preprocessing step that only adjusts
the normal vectors of the geometry, this method has no additional memory requirements
during the rendering process, and is especially applicable to real-time
visualizations. Furthermore, it may be applied to photorealistic as well as nonphotorealistic
visualizations, which both benefit from the modified normal vector
information. |
