    <dcterms:abstract xml:lang="eng">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.</dcterms:abstract>
