A novel approach to extract triangle strips for iso-surfaces in volumes

The Marching Cubes (MC) algorithm is a popular approach to extract iso-surfaces from volumetric data. This approach extracts triangles from the volume data for a specific iso-value using a table lookup approach. The lookup entry in the MC is a namevalue pair, where the name is a number that uniquely identifies a cube topology and the value is the set of triangles for that topology. The MC applies a divide-and-conquer strategy by subdividing the volume into cubes with voxels at each corner of the cube and processes these cubes in a specific order. Thus, for a user specified iso-value, the MC looks up triangles for each cube and thereby generates the whole iso-surface. Most modern graphics hardware renders triangles faster if they are rendered collectively as triangle strips as opposed to individual triangles. Therefore, in this paper we have modified the MC lookup table approach such that the name is the cube topology and the value is a sub-surface piece(s) and its face-index represent...
