NURBS surface generation by control points

2011 IEEE 3rd International Conference on Communication Software and Networks, 2011
A method on how to generate traditional quadrilateral NURBS surfaces, non-quadrilateral NURBS surfaces, such as triangle NURBS (Non-uniform Rational B-spline) surfaces and pentagon NURBS surfaces and their equidistant surfaces is presented. A NURBS surface is a bi-parameter surface, and the surface can be generated in accordance with its parameters ...

Curvature adapted triangulation of NURBS surfaces

13th Computational Fluid Dynamics Conference, 1997
Full exploitation of the sophisticated physical modeling capabilities of computational fluid dynamics has been hampered by the inability to generate high quality grids in a timely manner. Complex geometries further exacerbate grid generation difficulties.

NURBS for curve and surface design

Computer-Aided Design, 1993
From the Publisher: NURBS (nonuniform rational B-splines) promises to be the future geometry standard for free-form curves and surfaces. This volume contains recent results and new NURBS techniques and developments--the most important being curve/surface from the CAD/CAM industry. The book has been carefully refereed.

3D NURBS representation of surfaces for illumination

SPIE Proceedings, 2002
Use of NURBS surfaces to create facets on a reflecting surface will be considered. Specifically, the design of a reflector that generates a circular illuminance pattern will be investigated. Important considerations are: choice of variables used to represent a NURBS surface, total number of variables, parameterization and/or knot vector specification ...

Interactive Rendering of Deforming NURBS Surfaces

Computer Graphics Forum, 1997
Non‐uniform rational B‐splines (NURBS) has been widely accepted as a standard tool for geometry representation and design. Its rich geometric properties allow it to represent both analytic shapes and free‐form curves and surfaces precisely. Moreover, a set of tools is available for shape modification or more implicitly, object deformation.

Smooth connection of trimmed NURBS surfaces

Proceedings of the sixth ACM symposium on Solid modeling and applications, 2001
An automatic smooth surface connection method that has the capability of tension control is presented. Given two trimmed NURBS surfaces, the new method constructs a smooth connection surface to connect the trimming regions of the trimmed surfaces at the trimming curves.
