چکیده

We investigate univariate and bivariate binary subdivision schemes based on cubic B-splines with double knots. It turns out that double knots change the behaviour of a uniform cubic scheme from primal to dual. We focus on the analysis of new bivariate cubic schemes with double knots at extraordinary points. These cubic schemes produce C surfaces with the original Doo-Sabin weights.

A Construction of Bi orthogonal Functions to B splines with Multiple Knots

We present a construction of a re nable compactly supported vector of functions which is bi orthogonal to the vector of B splines of a given degree with multiple knots at the integers with prescribed multiplicity The construction is based on Hermite interpolatory subdivision schemes and on the relation between B splines and divided di erences The bi orthogonal vector of functions is shown to be...

Shape-preserving interpolation by splines using vector subdivision

We give a local convexity preserving interpolation scheme using parametric 2 C cubic splines with uniform knots produced by a vector subdivision scheme which simultaneously provides the function and its first and second order derivatives. This is also adapted to give a scheme which is both local convexity and local monotonicity preserving when the data values are strictly increasing in the x di...

GIT - GVU - 07 - 06 April 10 , 2007

Both the four-point and the uniform cubic B-spline refinement (i.e. subdivision) schemes double the number of vertices of a closed-loop polygonal curve P and produce sequences of vertices fj and bj respectively. We proposed to analyze a subdivision scheme Js that blends the rules of these two refinement methods to produce vertices of the form vj=(1–s)fj+sbj. Iterative applications of Js yield a...

NURBS-compatible subdivision surfaces

Two main technologies are available to design and represent freeform surfaces: NonUniform Rational B-Splines (NURBS) and subdivision surfaces. Both representations are built on uniform B-splines, but they extend this foundation in incompatible ways, and different industries have therefore established a preference for one representation over the other. NURBS are the dominant standard for Compute...

A C Four-Point Subdivision Scheme with Fourth Order Accuracy and its Extensions

We present a new four-point subdivision scheme that generates C curves. It reproduces cubic polynomials, has a basic limit function with support [−4, 3], and is close to being interpolatory. The refinement rule is based on local cubic interpolation, followed by evaluation at 1/4 and 3/4 of the refined interval. We investigate the approximation properties of this four-point scheme and extend it ...
