  abstract =   "This paper demonstrates the simple yet effective usage of
               height fields for interactive landscape visualizations using
               a ray casting approach implemented in the pixel shader of
               modern graphics cards. The rendering performance is output
               sensitive, i.e., it scales with the number of pixels rather
               than the complexity of the landscape. Given a height field
               of a terrain and a  topographic map or similar data as
               input, the vegetation cover is extracted and stored on top
               of the height field in a preprocess, enhancing the terrain
               with forest canopies or other mesostructure. In addition,
               enhanced illumination models like shadowing and ambient
               occlusion can be calculated at runtime with reasonable
               computational cost, which greatly enhances the scene
               realism. Finally, including the presented technique into
               existing rendering systems is relatively simple, mainly
               consisting of data preparation and pixel shader programming.",
