D-NURBS: a physics-based framework for geometric design
D-NURBS are physics-based models that incorporate physical quantities into the NURBS geometric substrate. Their dynamic behavior, resulting from the numerical integration of a set of nonlinear differential equations, produces physically …
Dynamic NURBS, also called D-NURBS, is a known dynamic version of the nonuniform rational B-spline (NURBS) which integrates free-form shape representation and a physically-based model in a unified framework.
[1303.6683] A Review of Dynamic NURBS Approach - arXiv.org
2013年3月26日 · Dynamic NURBS, also called D-NURBS, is a known dynamic version of the nonuniform rational B-spline (NURBS) which integrates free-form shape representation and a physically-based model in a unified framework. More recently, computer aided design (CAD) and finite element (FEM) community realized the need to unify CAD and FEM descriptions which ...
In this paper, we present Hierarchical D-NURBS as a new shape modeling representation that generalizes powerful, phy-sics-based D-NURBS for interactive geometric design. Our Hierarchical D-NURBS can be viewed as a collection of standard D-NURBS finite elements, organized hierarchically in a tree structure and subject to continuity constraints ...
Dynamic NURBS with geometric constraints for interactive sculpting
1994年4月1日 · Dynamic NURBS, or D-NURBS, are physics-based models that incorporate mass distributions, internal deformation energies, and other physical quantities into the popular NURBS geometric substrate. Using D-NURBS, a modeler can interactively sculpt curves and surfaces and design complex shapes to required specifications not only in the traditional ...

D-Nurbs | Guide books - ACM Digital Library
D-NURBS unify the features of the industry-standard geometry with the many demonstrated conveniences of interaction through physical dynamics. D-NURBS are physics-based models that incorporate mass distributions, internal deformation energies, forces, and other physical quantities into the NURBS geometric substrate.
D-NURBS: A physics-based geometric design framework - CORE
This paper presents dynamic NURBS, or D-NURBS, a physics-based generalization of non-uniform ra-tional B-splines. NURBS have become a de facto standard in commercial modeling systems because of their power to represent both free-form and common analytic shapes.
D NURBS A Physics Based Geometric Design Framework
A technique based on Non-Uniform Rational B-Splines (NURBS) and energy minimising deformable models to extract the brain surface accurately from MR head scans is presented and shows that the proposed model is capable of capturing the correct brain surface with a higher accuracy than the existing techniques.
