3D Visualization of electromagnetic environment

Electromagnetic radiation fields are ubiquitous in modern society. It is well known that long-term exposure in strong fields can result in bad effects to health due to some unknown mechanism. There are extensive research activities, in this paper, we study the simulation technique for spatial distribution of electromagnetic field in three dimensional construction of modern city which is supported by GIS. The key technologies of the electromagnetic environment simulation include terrain rendering, city building modeling and potential field visualization of electromagnetic data. The paper studies on the real-time visualization of volumetric data (electromagnetic fields) in complex scenes based on city building model. The study show that this technique mentioned in the paper is feasible, and can be applied to the study of electromagnetic environment simulation or the exploitation of the environment simulation system.
