Dimensionally absolutely stable but non-diagonalizable -meshes
Mao Shi
We construct an infinite family of rectangular \(T\)-meshes whose conformality-vector-space dimension is constant over all structurally similar geometric realizations, although the…
On the First Derivative Bounds for Rational Bézier Curves
Mao Shi
In this paper we investigate sharp upper bounds for the first derivative of rational Bézier curves. A long-standing conjecture posited that the linear bound $\|\mathbf{R}'(t)\| \le…
Counterexamples to a Conjecture on First Derivative Bounds of Rational Bézier Curves
Mao Shi
In this paper we present an explicit counterexample of degree , which shows that the conjecture proposed by Li et al. \cite{Li2013} regarding the first derivative bounds for r…
A note on convergence analysis of NURBS curve when weights approach infinity
Mao Shi
This article considers the convergence of NURBS curve when weights approach infinity. We shows that limit of NURBS curve dose not exist when independent variables weights approach…
Degree reduction of disk rational Bézier curves
Mao Shi
How to quickly and stably realize the degree reduction of the rational Bezier curve is an open problem in CAGD. Based on the weighted least squares method and weighted sum method o…
