A Prototype System for Light Propagation in Terrains

We present a prototype system for a simple version of electro-magnetic wave propagation prediction in rural areas, using a real-time exploration environment for very large topographic scenes. The wave propagation prediction algorithm is based on a simple line-of-sight approach, realized with a modified hidden surface removal algorithm. The system serves as a transmitter management tool, for interactively placing transmitters and studying the effects. Improvements according to the propagation prediction and automatic optimized placement of transmitters are current subjects of our research
