Abstract :
Surface models with unorganized triangular meshes have already been built based on the "retrieving topology from the ranged surface data," procedure using, for example, Delaunay tessellations from the scanned cloud points. The procedure is widely used; however, when a high-density scanning is required, ranging error goes beyond the scanning interval and high-precision reconstruction becomes impossible. To overcome the problem, a topology pre-assigned high-resolution (up to 1-10 mum) modeling procedure, is proposed for the irregular and complicated artifacts in shape. This procedure enables one always to construct a watertight model with potentially infinitesimal spatial resolutions for complete reproduction of the artifacts in shape and color, to manipulate the shape of the resulting model for virtual redesigning, restoration, cosmetic surgery, morphological anthropology and counterfeit detection. This proposal is practicable for all kinds of objects, and producing a versatile successive 3D shape manipulation.
