Until recently B-spline curves and surfaces (NURBS) were principally of interest to the computer aided design community, where they have become the standard for curve and surface description. B-spline curves and surfaces have been an enduring element throughout my pro fessional. The NURBS book covers all aspects of non-uniform rational B-splines necessary to design geometry in a computer aided environment. Basic B-spline features.
Hailed for its clear presentation, the book offers an excellent mix of mathematical formulas, examples, algorithms, and illustrations, making it accessible to a broad audience.

See our disclaimer. Until recently B-spline curves and surfaces NURBS were principally of interest to the computer aided design community, where they have become the standard for curve and surface description. Today we are seeing expanded use of NURBS in modeling objects for the visual arts, including the film and entertainment industries, art, and sculpture.
NURBS are now also being used for modeling scenes for virtual reality applications. These applications are expected to increase.
Consequently, it is quite appropriate for The. B-spline curves and surfaces have been an enduring element throughout my pro- fessional life. That material was obtained through the good graces of Bill Gordon and Louie Knapp while they were at Syracuse University. A paper of mine, presented during the Summer of at a Society of Naval Architects and Marine Engineers meeting on computer aided ship surface design, was arguably the first to examine the use of B-spline curves for ship design.

Piegl, L. Springer-Verlag, New York. ABSTRACT: InVesalius is an open-source software for reconstruction of computed tomography and magnetic resonance images, which allows the user to make analysis and segmentation of virtual anatomical models. Physical models can be printed with the aid of rapid prototyping, giving the medical community a reliable instrument to help planning surgeries. To offer the user more control over the model, this work describes a methodology and tool developed for NURBS parameterization that provides mechanisms for adjusting the shape or even selecting a particular region of interest of the surface.
Furthermore, the tool gives the option to export the final results of the process to a STEP file, which allows further edition in any well-known CAD software. Related Articles:. Jeffrey M. McKenzie, Donald I. Siegel, Laura K. Lautz, Martin H.
