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.

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.

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).

3D visualization of cardiac tagged magnetic resonance image data using Non-Uniform Rational B-Splines (NURBS)

Proceedings of the Seventh Indian Conference on Computer Vision, Graphics and Image Processing, 2010
The paper demonstrates accurate, anatomically correct 3D visualization of left and right ventricles of the human heart from tagged magnetic resonance imaging data. Tagged MRI reveals 3D structural and motion information that is incorporated into the visualized models. We use Non-Uniform Rational B-Splines (NURBS) for our purpose, that allow non-uniform
