Approximating conic sections by constrained Bézier curves of arbitrary degree
, 2012 In this paper, an algorithm for approximating conic sections by constrained Bézier curves of arbitrary degree is proposed. First, using the eigenvalues of recurrence equations and the method of undetermined coefficients, some exact integral formulas for ...

On the Difference Method for Drawing Conic Arcs
, 1994 The difference method is an efficient way to generate an inscribed polygon of a conic section. We address the implementation issues of the difference method, that is, how to choose the difference parameter and initial points so that the inscribed polygon

Construction of equations of dynamics of a given structure based on equations of program constraints
Современная математика: Фундаментальные направленияWe consider the problem of constructing a system of differential equations from a given set of constraint equations and reducing them to the form of Lagrange equations with dissipative forces that ensure stabilization of the constraints. We determine the

Plane sections of space curves in positive characteristic
Le Matematiche, 2006 It is known that if C is a curve of degree d ≥ 6 in P^3 over an algebraically closed field of characteristic 0 such that its plane section is contained in an irreducible conic, then C lies on a quadric surface.

A Conic Section Classifier and its Application to Image Datasets ∗
, 2008 Many problems in computer vision involving recognition and/or classification can be posed in the general framework of supervised learning. There is however one aspect of image datasets, the high-dimensionality of the data points, that makes the direct ...

Necessary and sufficient conditions for rational quartic representation of conic sections
, 2007 Conic section is one of the geometric elements most commonly used for shape expression and mechanical accessory cartography. A rational quadratic Bézier curve is just a conic section. It cannot represent an elliptic segment whose center angle is not less
