چکیده
This note derives formulae for Gaussian and mean curvatures for tensor-product and triangular rational Bézier patches in terms of the respective control meshes. These formulae provide more geometric intuition than the generic formulae from differential geometry.

An Optimal G^2-Hermite Interpolation by Rational Cubic Bézier Curves
In this paper, we study a geometric G^2 Hermite interpolation by planar rational cubic Bézier curves. Two data points, two tangent vectors and two signed curvatures interpolated per each rational segment. We give the necessary and the sufficient intrinsic geometric conditions for two C^2 parametric curves to be connected with G2 continuity. Locally, the free parameters w...
متن کاملSubdivision Algorithms and Convexity Analysis for Rational Bézier Triangular Patches
Triangular surfaces are important because in areas where the geometry is not similar to rectangular domain, the rectangular surface patch will collapse into a triangular patch. In such a case, one boundary edge may collapse into a boundary vertex of the patch, giving rise to geometric dissimilarities (e.g. shape parameters, Gaussian curvature distribution, cross boundary continuities etc.) and ...
متن کاملConstruction of Bézier surface patches with Bézier curves as geodesic boundaries
Given four polynomial or rational Bézier curves defining a curvilinear rectangle, we consider the problem of constructing polynomial or rational tensor–product Bézier patches bounded by these curves, such that they are geodesics of the constructed surface. The existence conditions and interpolation scheme, developed in a general context in earlier studies, are adapted herein to ensure that the ...
متن کاملRational Bézier Formulas with Quaternion and Clifford Algebra Weights
We consider Bézier-like formulas with weights in quaternion and geometric (Clifford) algebra for parametrizing rational curves and surfaces. The simplest non-trivial quaternionic case of bilinear formulas for surface patches is studied in detail. Such formulas reproduce well known biquadratic parametrizations of principal Dupin cyclide patches, and are characterized in general as special Darbou...
متن کاملRepresentation of Dupin cyclides using quaternions
Dupin cyclides are surfaces characterized by the property that all their curvature lines are circles or lines. Spheres, circular cylinders, cones and tori are particular examples. We introduce a bilinear rational Bézier-like formula with quaternion weights for parametrizing principal patches of Dupin cyclides. The proposed construction is not affine invariant but it is Möbius invariant, has low...
