Object-oriented paradigm for NURBS curve
โœ Richard D Fuhr; Lwo Hsieh; Michael Kallay ๐Ÿ“‚ Article ๐Ÿ“… 1995 ๐Ÿ› Elsevier Science ๐ŸŒ English โš– 846 KB

The prevailing paradigm in the design of curve and surface algorithms could be described as being control-points oriented. The limitations of this approach are explored, and an alternative paradigm is presented that combines object-oriented design with two well known approximation algorithms that ar

Knot-removal algorithms for NURBS curves
โœ W. Tiller ๐Ÿ“‚ Article ๐Ÿ“… 1992 ๐Ÿ› Elsevier Science ๐ŸŒ English โš– 647 KB

The paper presents pseudocode aloorithms, c-lanouaoe code, and error analysis for removino knots from rational B-spline curves and surfaces. Efficient and easy-to-use aloorithms are presented that, with one call, remove all the removable knots from a B-spline curve or surface.

Explicit matrix representation for NURBS

The matrix forms for curves and surfaces were largely promoted in CAD/CAM. In this paper we have presented two matrix representation formulations for arbitrary degree NURBS curves and surfaces explicitly other than recursively. The two approaches are derived from the computation of divided differenc

This paper presents an algorithm of modifying free-formed NURBS curve/surface for offsetting without local self-intersecting. The method consists of (1) sampling a number of points from a progenitor curve/surface based on second derivatives; (2) checking the curvature or maximum curvature of the pro
