NURBS in VRML

Proceedings of the fifth symposium on Virtual reality modeling language (Web3D-VRML), 2000
In the days of VRML 1.0, NURBS seemed to be too complex to be adapted to the specification. Current development of hardware compels us to reevaluate this idea: While CPU clocks break the 1-GHz barrier, users still have to cope with 56K modems. NURBS meet exactly these demands.

DNurbs: DNA modeled with NURBS

Journal of Molecular Graphics, 1994
DNurbs (dee-in-urbs) are a small number of bicubic patches wrapping each base pair in complementary DNA. NURBS, the nonuniform rational B-spline surfaces now popular in computer graphics, are employed for the patches. Control points for the surface patches are generated from the molecular surface based on canonical base pairs.

Single-Patch NURBS Face

2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System, 2007
We describe a novel NURBS surface fitting method to a human face model. Our first step is to resample of the original mesh model. The next step we fit a tensor product NURBS surface to the grid points. Our method is characteristic in that we use only one patch to fit the model.

Curves and NURBS

2010
In this chapter we are going to explore some advanced modeling techniques, mostly suited for curved or wirelike structures that would prove tricky to model as a straight polygon mesh. The techniques covered in Chapter 3 are good for modeling most items, but there are times when a specialist tool makes the job easier.

Watermarking NURBS Surfaces

2005
The popularity of the worldwide web and the easy availability of the digital content has brought the security issues to the forefront. NURBS is widely used in computer-aided geometry design and computer graphics for its strong representative properties. In this paper, we present a blind watermarking algorithm for NURBS surfaces.

NURBS Warps

2008
Standard Free-Form Deformation (FFD) models built upon tensor-product B-Splines have been proved useful to model the warp between two views of a deformable scene. In this paper, we show that the standard FFD is in fact the affine projection of a threedimensional surface represented by a tensor-product B-Spline.

On NURBS: a survey

IEEE Computer Graphics and Applications, 1991
Nonuniform rational B-spline (NURBS) curves and surfaces, which are based on rational and B-splines, are defined. The important characteristics of NURBS that have contributed to their wide acceptance as standard tools for geometry representation and design are summarized.
