The Research On Visualization In The 3D Electromagnetic Field Calculation By The Finite Element Method

At first, the developments and shortage of the Electromagnetic Computation and its engineering application are introduced in this paper. The method is given for display of three-dimensional objects on the screen. The application of scientific visualization and OpenGL is discussed in post-process of electromagnetic computation. With the help of OpenGL technology, a new approach is presented to the display of 3D meshes by Microsoft visual C++. The visualization of 3D vector data is realized. The extraction of Isosurfaces for 3D finite element analysis is finished using improved MC algorithm.
