Implicitization of High Degree Tensor Product Cagd Entities
نویسندگان
چکیده
We focus on the implicitization of parametric CAGD entities which are supposed to be of tensor product type. The presented approach is featured by its ability to treat polynomial or rational splines having a great number of control points. For B-splines, we describe a method of exactly obtaining the Fourier coefficients without using quadrature rules. As for NURBS, a preprocessing step is necessary to convert them into an easy structure. The implicitization is obtained from the convolutions of the parametric CAGD entities. To speed the computations, one can use FFT based algorithms.

On the Validity of Implicitization by Moving Quadrics for Rational Surfaces with No Base Points
Techniques from algebraic geometry and commutative algebra are adopted to establish suucient polynomial conditions for the validity of implicitization by the method of moving quadrics both for rectangular tensor product surfaces of bi-degree (m; n) and for triangular surfaces of total degree n in the absence of base points.
متن کاملApplying Functional Networks to Fit Data Points from B-Spline Surfaces
Recently, a powerful extension of neural networks. the so-called functionaI networks. has been introduced / I /. This kind of networks exhibits more versatility than neural networks so they can be successfully applied to several problems in Cotputer-Aided Geometric Design (CAGD). As an illustration, the simplest functional network representing tensor product surfaces is obtained. Then, function...
متن کاملProduct version of reciprocal degree distance of composite graphs
A {it topological index} of a graph is a real number related to the graph; it does not depend on labeling or pictorial representation of a graph. In this paper, we present the upper bounds for the product version of reciprocal degree distance of the tensor product, join and strong product of two graphs in terms of other graph invariants including the Harary index and Zagreb indices.
متن کاملNew Improvement in Interpretation of Gravity Gradient Tensor Data Using Eigenvalues and Invariants: An Application to Blatchford Lake, Northern Canada
Recently, interpretation of causative sources using components of the gravity gradient tensor (GGT) has had a rapid progress. Assuming N as the structural index, components of the gravity vector and gravity gradient tensor have a homogeneity degree of -N and - (N+1), respectively. In this paper, it is shown that the eigenvalues, the first and the second rotational invariants of the GGT (I1 and ...
متن کاملA de Casteljau Algorithm for Bernstein type Polynomials based on (p, q)-integers in CAGD
In this paper, a de Casteljau algorithm to compute (p, q)-Bernstein Bézier curves based on (p, q)integers is introduced. We study the nature of degree elevation and degree reduction for (p, q)-Bézier Bernstein functions. The new curves have some properties similar to q-Bézier curves. Moreover, we construct the corresponding tensor product surfaces over the rectangular domain (u, v) ∈ [0, 1]× [0...
