This article presents a new and direct approach for fitting a subdivision surface from an irregular and dense triangle mesh of arbitrary topological type. All feature edges and feature vertices of the original mesh model are first identified. A topology-and feature-preserving mesh simplification algorithm is developed to further simplify the dense triangle(More)
In this paper, based on the possibility distribution and semantic measure of fuzzy data, an extended object-oriented database model to handle imperfect as well as complex object in the real-world is introduced. Some major notions in object-oriented databases such as objects, classes, object-classes, relationships , subclass/superclass and multiple(More)
This paper presents a new interpolatory subdivision scheme for quadrilateral meshes based on a 1–4 splitting operator. The scheme generates surfaces coincident with those of the Kobbelt interpolatory subdivision scheme for regular meshes. A new group of rules are designed for computing newly inserted vertices around extraordinary vertices. As an extension(More)
