Removing short edges from the extracted iso-surface with a two-pass mesh decimation algorithm
Grahic Jump Location
Iso-surface Sl with iso-distance lines (dotted) and distance gradients gv and normals nv at two vertices of the mesh
Grahic Jump Location
Distance gradient and normal vector at a vertex in four different situations. The gray-shaded region indicates the region enclosed by the iso-surface and the dashed line its medial axis.
