Reuse of a geometric model for shape approximation

A robust procedure of three-dimensional shape modeling for an object approximation is proposed. A solid model is first prepared or reused for the prototype and then transferred to the model that approximates the shape of the object. Vertex geometry of the prototype is modified based on the multidirectional silhouettes and light stripe pattern projection. Topology of the mesh, shape and connectivity of the vertices, of the prototype is conserved throughout the modeling process. Stable meshing and accurate shape approximation are achieved, starting from a simple or a dedicated model with desired meshes. A dedicated male sculpture and a simple cylinder with quadrilateral meshes are demonstrated for the shape approximation. This eliminates the laborious modeling procedures, reusing a proven or simple and stable model, and the complicated camera calibrations.
