Matching free-form surfaces
In this work, the matching problem between two free-form parametric surfaces, S 0 (u, v) and S 1 (u, v), has been considered in the context of a "rst stage of the metamorphosis process, which is de"ned as gradual and continuous transformation of one key shape into another. A method is presented to approximate the two reparametrization functions, r(u, v) and t(u, v), via a discrete sampled set o...
متن کاملMachining Free-Form Surfaces
This paper presents an analytical method for planning an efficient tool-path in machining free-form surfaces on 3-axis milling machines. This new approach uses a nonconstant offset of the previous tool-path, which guarantees the cutter moving in an unmachined area of the part surface and without redundant machining. The method comprises three steps: (1) the calculation of the tool-path interval...
متن کامل3D Free-form Modeling with Variational Surfaces
We describe a free-form stroke-based modeling system where objects are primarily represented by means of variational surfaces. Although similar systems have been described in recent years, our approach achieves both a good performance and reduced surface leak problems by employing a coarse mesh as support for constraint points. The prototype implements an adequate set of modeling operations, “u...
