Abstract
En 中文
The structuring Of Surface meshes is a labor intensive task in reverse engineering. For example, in CAD, scanned triangle meshes must be divided into characteristic/uniform patches to enable conversion into high-level spline surfaces Typical industrial techniques, like rolling ball blends, are very labor intensive We provide a novel, robust and quick algorithm for the automatic generation of a patch layout based on a topology consistent feature graph The graph separates the Surface along feature lines into functional and geometric building blocks Our algorithm then thickens the edges of the feature graph and forms new regions with low varying curvature Further, these new regions - so-called fillets and node patches - will have highly smooth boundary curves, making the algorithm an ideal preprocessor for a subsequent spline fitting algorithm.
