| Popis: | A simple efficient method is proposed to reduce the total number of triangles in an isosurface extraction method based on tetrahedral decomposition. We slightly perturb the input volumetric data so that useless small and thin triangles are removed. The perturbed volumetric data contain the exact isovalues from which a mesh is extracted. Since the proposed method is a pre-process of an isosurface extraction, it is not necessary to modify the mesh structure unlike the other similar methods. |
