Extraction and visualization of semitransparent isosurfaces for 3-D finite element analysis

One of the most challenging ideas in the calculation of EM fields is to use an isosurface visualization for the post-processing of the large amount of output data obtained from various numerical methods, such as the finite element method (FEM). In this paper, the authors present a newly developed multipurpose visual system for the 3-D display of scalar variables using isosurfaces visualization. The proposed visualization method is based on the extraction of a set of triangular patches using an improved marching cube algorithm, construction of the isosurface and their interactive 3-D display.
