Abstract:

3D visualization of the electromagnetic environment is one of the most important research fields on virtual battle space. An approach to visualizing the 3D electromagnetic environment is presented by the multilayer of Marching Tetrahedra (MT) isosurfaces. The electromagnetic environment is represented by the multiisosurface which is extracted from the power volume data calculated using the LongleyRice radio propagation model which takes into account the effects of terrain and atmosphere. The inner detail of power volume data is presented with the approach in the isosurface rendering method instead of in the traditional mesh rendering method. To improve the performance, the approach uses GPU to accelerate the multiisosurface extraction based on MT and decreases the burden of CPU. Finally, an interactive 3D visualization system of the electromagnetic environment is implemented on virtual battle space, and the result shows that the approach can visualize the 3D electromagnetic environment, and it can also assist user to position radio and make the plan of the wireless communication.
