Non-uniform-rational-B-splines (NURBS) in illumination design

Frontiers in Optics, 2003
After a brief explanation of NURBS concepts [1], this work considers the use of NURBS surfaces in illumination system design. An important design case is creating a uniform illuminance distribution on a target plane. This work demonstrates an optimization design approach that results in an efficient faceted reflector system.

Smooth non-uniform rational B-spline (NURBS) machining with kinematic limit for short linear segments

International Journal of Computer Integrated Manufacturing, 2011
Set of methods based on non-uniform rational B-spline (NURBS) are proposed in this article, which are adopted to improve the smoothness during short linear numerical control (NC) codes machining. The smoothness refers to two aspects: the contour fairness of CL trajectory and the machining stability of the machine tool.

Review on Non Uniform Rational B-Spline (NURBS): Concept and Optimization

Advanced Materials Research, 2014
This paper is to provide literature review of the Non Uniform Rational B-Splines (NURBS) formulation in the curve and surface constructions. NURBS curves and surfaces have a wide application in Computer Aided Geometry Design (CAGD), Computer Aided Design (CAD), image processing and etc.

Robot motion planning in a dynamic environment using offset Non-Uniform Rational B-Splines (NURBS)

2011 IEEE International Conference on Industrial Technology, 2011
A new method of collision free motion path planning using Non uniform rational B- Spline curves for mobile robots is addressed in this paper. Obstacles of polygonal nature are used and the navigation occurs in a dynamic environment. Mathematical Modeling with vector addition technique is used to compute the set of points which will form the final path.

Three Dimensional Solid Modeling of Geo-Objects Using Non-Uniform Rational B-Splines (NURBS)

, 1992
The world of the geologist is, of course, multi-dimensional, but it is an unfortunate fact that traditional interpretation methods (e.g., contoured maps, cross sections, fence diagrams, isometric surfaces) limit the view of this world to two dimensions, or at best quasi-three dimensions (Fisher and Wales, 1990).
