Item Expressive Illumination of Foliage Based on Implicit Surfaces(The Eurographics Association, 2007) Luft, Thomas; Balzer, Michael; Deussen, Oliver; D. Ebert and S. MerillouThis 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 its general shape and local density, 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.
