摘要： A feature edge extraction technique supports automatic creation of a solid model from a 3D or triangular mesh model. The technique extracts feature edges from the 3D mesh model according to a global normal-line evaluation method and an improved watershed method. The technique uses data related to the 3D mesh model, defines an area with a Euclidean distance, globally evaluates normals of triangles in the area, calculates edge and vertex feature values, carries out discretization and differentiation on the calculated vertex feature values, extracts feature edges satisfying requirements, divides the mesh model into segments each consisting of connected triangles according to the improved watershed method that is capable of grouping vertexes, extracts the boundaries of each segment as feature edges, allows a user to interactively select required feature edges from among the extracted feature edges, and outputs data related to the selected feature edges.

摘要： An apparatus, a method and a program segment mesh model data into analytic surfaces based on robust curvature estimation and region growing by extracting, from mesh model data, analytic surface regions (planar, cylindrical, conical, spherical and toric surface regions) and by automatically recognizing fillet surface regions, linear-extrusion surface regions and surface regions of revolution from the extracted regions and edges. The apparatus, method and program input mesh model data, find sharp vertices in the mesh model data, calculate principal curvatures at each non-sharp vertex, create, from the calculated principal curvatures, seed regions each being considered to belong to an analytic surface region and including a set of linked vertices, extract analytic surface regions by growing the seed regions, recognize fillet surface regions, linear-extrusion surface regions and surface regions of revolution in the extracted analytic surface regions, and output information concerning the extracted analytic surface regions and information concerning the recognized regions.
