Abstract: This paper describes an efficient algorithm for real-time terrain shadowing by directional light. The main concept for this algorithm is fast preprocessing stage in model space that dramatically speeds up shadow calculation for pixels in rasterization phase. Preprocessing is very fast and can be performed every frame still achieving interactive frame rates. Therefore it is suitable for dynamic height field and moving light source visualization.
