Abstract:

A band rendering method for electromagnetic environment was presented. The electromagnetic environment is represented by electromagnetic radiation power density of radars, when the data band computing is carried, a volumetric data for all bands is got. The volumetric data was then divided into sub-regions for each band based on each radar effect. Ray casting algorithm was used to render electromagnetic environment in which the transfer function was expressed as a set of color lookup tables for each band, different band has different color. Among all color lookup tables, there are some same colors for rendering the combined effects of all bands. A real-time rendering method was carried out using compute unified device architecture. Experiments show that the rendering images can display the distribution of bands and the combined effects of all bands for electromagnetic environment, and are helpful for understanding the electromagnetic environment intuitively.

Key words: electromagnetic environment, band rendering, ray casting, transfer function design, compute unified device architecture
