A prototype system for light propagation in terrains

Abstract

We present a prototype system for a simple version of electromagnetic 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.
