Texture Mapping on NURBS Surface [PDF]
Texture mapping allows high resolution details over 3D surfaces. Nevertheless, texture mapping has a number of unresolved problems such as distortion, boundary between textures or filtering. On the other hand, NURBS surfaces are usually decomposed into a

An explicit and rapid intersection algorithm of plane and NURBS surface in CNC surface machining [PDF]
To address the challenge of plane-surface intersection in toolpath planning for CNC surface machining, a rapid intersection algorithm between a plane and a NURBS surface is proposed, which can provide an explicit Non-Uniform Rational B-Spline (NURBS ...

Comparison Between T-Spline Surface and NURBS Surface [PDF]
This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50 ...

Three-dimensional reconstruction of industrial parts from a single image [PDF]
This study proposes an image-based three-dimensional (3D) vector reconstruction of industrial parts that can generate non-uniform rational B-splines (NURBS) surfaces with high fidelity and flexibility. The contributions of this study include three parts:

NURBS-Based Parametric Design for Ship Hull Form
Recently, the NURBS technique has been widely used in the 3D design software for ships. However, in most research, the NURBS technique is only applied to the mathematical representation of hull curves and surfaces, and the parametric deformation of hull ...

Interactive rendering of NURBS surfaces [PDF]
[Resumo] As superficies NURBS (Non-uniform rational B-splines) son unhas das primitivas más empregadas no modelado de alta calidade nas ferramentas CAD/CAM e o software gráfico. Dado que a avaliación directa de superficies NURBS na GPU é unha tarefa altamente complexa, a aproximación máis común para o render de NURBS é a súa conversión previa na CPU en

Quasi-Isotropic Initial Triangulation of NURBS Surfaces [PDF]
Isotropic triangulation of NURBS surfaces provides high quality triangular meshes, where all triangles are equilateral. This isotropy increases representation quality and analysis accuracy. We introduce a new algorithm to generate quasi-isotropic triangulation on NURBS surfaces at once, with no prior meshing. The procedure consists of one front made of

Polar NURBS Surface with Curvature Continuity [PDF]
AbstractPolar NURBS surface is a kind of periodic NURBS surface, one boundary of which shrinks to a degenerate polar point. The specific topology of its control‐point mesh offers the ability to represent a cap‐like surface, which is common in geometric modeling.
