Triangular Bézier Approximations to Constant Mean Curvature Surfaces
We give a method to generate polynomial approximations to constant mean curvature surfaces with prescribed boundary.
متن کاملSome properties of exact geodesics on triangular mesh surfaces
Computing exact geodesic paths on triangular mesh surfaces is an important operation in many geometric algorithms. In this paper we show several particular examples that reveal four interesting properties and three observations of exact geodesic computations on triangular mesh surfaces. The properties are proved and observations are drawn from experimental results using practical models. With t...
متن کاملA Thin-plate CAD Mesh Model Splitting Approach Based on Fitting Primitives
Extracting structural information from mesh models is crucial for Simulation Driven Design (SDD) in industrial applications. Focusing on thin-plate CAD mesh models (the most commonly used parts in electronic products such as PCs, mobile phones and so on), we present an algorithm based on primitive fitting for segmenting thin-plate CAD mesh models into parts of three different types, two of whic...
متن کاملTransformation of a closed 3D triangular mesh to a quadrilateral mesh based on feature edges
In this paper, we propose a method of applying the Q-Morph to the closed three-dimensional triangular mesh. The Q-Morph is the method in order to transform the triangular mesh to the quadrilateral mesh. The Q-morph begins quadrilateral transformation from the initial front edges which are usually the boundary of the 2D domain. Also, the Q-Morph can be applied to the 3D domain. But, the closed 3...
متن کاملTopologically consistent trimmed surface approximations based on triangular patches
Topologically consistent algorithms for the intersection and trimming of free-form parametric surfaces are of fundamental importance in computer-aided design, analysis, and manufacturing. Since the intersection of (for example) two bicubic tensor-product surface patches is not a rational curve, it is usually described by approximations in the parameter domain of each surface. If these approxima...
