Abstract: According to the features of huge 3D-FEM models, basic requirements of
visualization and key algorithms are summarized. Then, a simple and reliable algorithm of fast
rendering is prepared for different tasks of grid, unit, slice visualization and color contour
respectively. Through contrastive testification of specific examples and typical business software
by contrast, the feasibility and superiority of the algorithm is initially demonstrated, which can
contribute to simplification of preparation for huge FEM program.
