- W2134449259 abstract "Abstract We present an approach for the reconstruction andapproximation of 3D CAD models from an unorganized collection ofpoints. Applications include rapidreverse engineering of existing objects for usc in asynthetic computer environment, including computeraided design and manufacturing. OUf reconstructionapproach is flexible enough to permitinterpolation ofboth smoothsurfaces and sharp features, while placing few restrictions on the geometry or topology ofthe object.Our algorithm is based on 3D Delaunay triangulations and a-shapes to compute an initial trianglemesh approximating the shape ofthe object. A meshdecimation technique is applied to the dense triangle mesh to build a simplified approximation, whileretaining important topological and geometric characteristics ofthe model. Thereduced mesh is interpolated wit.h piecewise algebraic surface patches, whichapproximate the original points.The resulting model is suitable for typical CADmodeling and analysis applications. 1 Introduction" @default.
