چکیده
Zheng, J., G Wang and Y. Liang, Curvature continuity between adjacent rational B&ier patches, Computer Aided Geometric Design 9 (1992) 321-335. This paper discusses the cutvature continuity between two adjacent rational BCzier surfaces which may be rectangular or triangular patches. The necessary and sufficient conditions are derived, and further, a series of simple sufficient conditions are developed. These conditions are either descriptive or constructive. Therefore with them one can both check the geometric continuity between two surfaces and construct a rational surface possessing curvature continuity with a given rational patch along a certain boundary. This is an important feature in CAGD applications.

Construction of rational surface patches bounded by lines of curvature
The fact that the Darboux frame is rotation–minimizing along lines of curvature of a smooth surface is invoked to construct rational surface patches whose boundary curves are lines of curvature. For given patch corner points and associated frames defining the surface normals and principal directions, the patch boundaries are constructed as quintic RRMF curves, i.e., spatial Pythagorean–hodograp...
متن کاملCurvature tensor computation by piecewise surface interpolation
Estimating principal curvatures and principal directions of a smooth surface represented by a triangular mesh is an important step in many CAD or graphics related tasks. This paper presents a new method for curvature tensor estimation on a triangular mesh by replacing flat triangles with triangular parametric patches. An improved local interpolation scheme of cubic triangular Bézier patches to ...
متن کاملAn 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 کاملApproximate Continuity for Functional, Triangular Bézier Patches
In this paper, we investigate a relaxation of the C continuity conditions between functional, triangular Bézier patches, allowing for patches to meet approximately C. We analyze the cross boundary continuity of functional triangular Bézier patches, and derive a bound for the discontinuity in the normals between two patches based on their control points. We test our discontinuity bound on a simp...
متن کاملCircle to Circle Transition with a Single Ph Quintic Spiral
This paper theoretically describes how to compose a single Pythagorean hodograph (PH) quintic Bézier spiral segment, between two circles with one circle inside the other. A spiral is free of local curvature extrema, making spiral design an interesting mathematical problem with importance for both physical and aesthetic applications. The curvature of a spiral varies monotonically with arc-length...
