3D NURBS representation of surfaces for illumination
Thomas L. R. Davenport · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 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, and where to use algorithmic vs. optimization approaches.
