Visualization of Two-Dimensional Electromagnetic Situation

Two-dimensional electromagnetic situation is very important in the research of battle-field electromagnetic situation and electromagnetic management. An improved algorithm of going forward beginning with margins is put forward to build Delaunay triangles. The speed of constructing Delaunay triangles is greatly improved. The visualization of two-dimensional electromagnetic situation was realized by interpolating, tracing iso-points, smoothing iso-lines and constructing iso-areas. The result of simulation shows that the speed of drawing pictures of two-dimensional electromagnetic situation is comparatively fast.
