Adjusting the polygon data correction mannered and polygon data correction program and polygon data which

摘要

PROBLEM TO BE SOLVED: To effectively solve a noise problem of polygon data by removing noise effectively from specific portions defined as features in a surface shape described by the polygon data.;SOLUTION: A polygon data correction device for correcting polygon data D1 describing a surface shape of an object to produce corrected polygon data D3 has a feature extraction parameter specification means C4 for specifying parameters for extracting from the polygon data a feature that is a geometric feature shape included in the surface shape of the object, to generate feature extraction parameters D4, a feature extraction means C3 for extracting the feature from the polygon data according to the generated feature extraction parameters and searching for feature belonging polygons supposed to be included in the extracted feature according to predetermined criteria, to create feature data D2, and a polygon generation means C6 for generating a polygon on the feature extracted in the feature extraction process.;COPYRIGHT: (C)2007,JPO&INPIT
