Circle as a P-spline Curve

چکیده
The objective of the paper is to continue the study of an interesting class of rational splines in polar coordinates, introduced by SS anchez-Reyes 17] and independently by de Casteljau 6]. We refer to these curves as p-splines. They are a generalization of certain analogous of B ezier curves in polar coordinates which we call p-B ezier. We present an alternative way to have an exact representation of a circular arc using p-B ezier and p-spline curves. This result has a direct application in the construction of p-spline surfaces in spherical coordinates.

Continuity Method based on C-B Spline Curves and C-Bézier
C-B spline can not represent semi-circle and semi-elliptical arcs precisely. This paper will discuss the nature of C-B spline’s and C-Bézier curve’s endpoints. Then, on the basis of the analysis of their characteristics and by means of adding control points to make C-B spline dominate the first and last vertices of the polygon and get tangency with the first and end sides. Thus it has given out...
متن کاملConical representation of Rational Quartic Trigonometric Bèzier curve with two shape parameters
I. Introduction Rational spline is a commonly used spline function. In many cases the rational spline curves better approximating functions than the usual spline functions. It has been observed that many simple shapes including conic section and quadric surfaces can not be represented exactly by piecewise polynomials, whereas rational polynomials can exactly represent all conic sections and qua...
متن کاملModeling and Animation of Generalized Cylinders with Variable Radius O set Space Curves
A method is presented for the modeling and animation of generalized cylinders with variable radius ooset space curves. The boundary surface of a generalized cylinder is constructed: either as a translational sweep of cross-sectional curves along the skeleton curve, or as a rotational sweep of proole curves around the skeleton curve. The cross-sectional curves are computed as the variable radius...
متن کاملOn the Simple Closed Curve Property of the Circle and the Fashoda Meet Theorem for It
First, we prove the fact that the circle is the simple closed curve, which was defined as a curve homeomorphic to the square. For this proof, we introduce a mapping which is a homeomorphism from 2-dimensional plane to itself. This mapping maps the square to the circle. Secondly, we prove the Fashoda meet theorem for the circle using this homeomorphism. In this paper x, y, z, u, a are real numbe...
متن کاملCircle Approximation by Quartic G2 Spline Using Alternation of Error Function
In this paper we present a method of circular arc approximation by quartic Bézier curve. Our quartic approximation method has a smaller error than previous quartic approximation methods due to the alternation of the error function of our quartic approximation. Our method yields a closed form of error so that subdivision algorithm is available, and curvaturecontinuous quartic spline under the su...
