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.

The paper implements a dynamic system for multi-angle glass-free 3D video, the technology for playing content acquisition have higher requirements. The system using the camera matrix, gathering content for multi-angle shooting, and then after decoding, correction, synthesis, processing changes have sustained multiple angles of video images, in order to achieve the Glass-Free 3D viewing . System uses Java to achieve the driver. As the experimental results shows that the camera capturing problems like distortion and image alignment are solved and the dynamic full HD video with four view angles realized.
