Fast Ray-Tracing for Computing N-Bounces Between Flat Surfaces at Indoor/Outdoor Propagation

A new ray-tracing method has been developed to compute the propagation at indoor/outdoor environments considering n-bounces. The Angular Z-Buffer algorithm (AZB) together with the A* heuristic search method are considered. The approach is very efficient allowing the analysis of high-order bounces in reasonable CPU-time utilizing an affordable computer.
