We used techniques and software developed for open source game engine to: 1) The ray tracing physics algorithm for path loss, reflection and multiple diffraction. 2) The efficient use of graphic processing unit (GPU) and the multiple processor of the CPU. %K Juego %K Código abierto %K Sistemas abiertos %K Gráficos por computador %K Robótica y control automático %K Autonomous robots %~ GOEDOC, SUB GOETTINGEN
