A visual simulation of ray propagation for wireless communication systems
説明
In order to analyze the urban propagation environment of electromagnetic waves, we propose a beam tracing method with a subdivision technique, in which the beam is generated by three rays. According to reflection of the rays on the buildings or ground, additional rays are generated adaptively and the beam is subdivided automatically. After generation of the set of beams, we transform the electromagnetic wave propagation data into volume data. Then one can visualize the data of propagation at any viewpoint by the so-called ray casting algorithm, which is one of the most useful methods in computer graphics.
