Abstract :
This paper proposes a practical, topologically robust and ranging-error resistive shape modeling procedure that approximates a real 3D object, such as an archeological artifact, with the matrix-formatted organized meshing, enabling high-density scanning for high-resolution reconstruction, the successive 3D shape manipulation and reuse of the reconstructed model for morphological approximation of anthropological and anthropoid skulls. A face array listing (topology), which defines the vertex (mesh point) connectivity and the shape of the mesh, is pre-assigned to meet the desired scanning. Stable meshing, and hence, an accurate approximation, free from the shape ambiguity unavoidable in the widely used "retrieving topology from geometry" modeling procedures based on, for instance, Delaunay tessellations, is then accomplished. This proposal allows a practical and versatile reconstruction of the skull and the successive 3D shape modification reused for anthropological and anthropoid morphology based on their local shape-oriented characteristics, not on simple criteria, such as a root-mean-square deviation
