Smoothing of curves and surfaces
Using BCrier-techniques or B-spline-techniques for lntrrpolation or approximation of cur\es or wrfaces inflection pants or changes of sign of the Gaussian curvature occaaionallq occur. Inflection polnth or changer of sign of Gaussian curvature are ur&vwd in some applications. notably the fairlng of ship liner or the fairlng of car body surfaces. In the present contribution we mtroduce ~1 simple...
متن کاملSpline Smoothing on Surfaces
We present a method for estimating functions on topologically and/or geometrically complex surfaces from possibly noisy observations. Our approach is an extension of spline smoothing, using a Þnite element method. The paper has a substantial tutorial component: we start by reviewing smoothness measures for functions deÞned on surfaces, simplicial surfaces and differentiable structures on such s...
متن کاملIterative Smoothing of Curves and Surfaces
Algorithms for drawing smooth curves and surfaces are well-known but may be too expensive in CPU time to use for certain high speed interactive graphics applications. This paper looks at some new geometrically-based smoothing algorithms that arrive at the final smooth curve or surface after the application of an infinite number of iterations of the algorithm using subdivision refinement. When C...
متن کاملBoolean and smoothing of discrete polygonal surfaces
The development of discrete solid models from imaging has become a common practice in reverse engineering. This has motivated the need for tools to combine and manipulate discrete boundary representation of objects. Despite the importance of this problem in computer aided engineering, there is a lack of robust and efficient open-source implementations of Boolean operations for discrete geometri...
متن کاملBlending Surfaces by Smoothing Pde Splines
This work is concerned with how we can mix conditions of both interpolation and approximation in order to find a blending surface joining two or more surfaces when approximating a given data point set, and modelled from a certain partial differential equation. We establish a variational characterization for the solution of this problem and we establish some convergence result. Finally, we discr...
