Abstract
A modeling system is provided which retrieves from memory the 3D virtual model of an object; extract an outer surface of the 3D virtual model, the outer surface including a plurality of faces; identify feature curves in each of the plurality of faces of the outer surface; generate a parameterized surface from the identified feature curves; and output the feature curves and the parameterized surface. The system may generate a list of feature curve pairs that are adjacent to one another; obtain face pairs corresponding to the feature curve pairs; obtain and add a list of faces in the outer surface to a connectivity graph mapping points in 3D space to the feature curves; for each pair of connected faces, evaluate whether an angle difference between normals of the connected faces is greater than a threshold; and then extract a feature curve based on the pair of connected faces.
