Industrie- und Handelskammer in Wien data. We show how to build an isocurve through any point and how to choose which isocurves are computed. The isocurves are used to build a tensor product surface for each component of the model isomorphic to a cylinder.

,Nach der Versammlung – das Protokoll,rmally. The curves are defined in Bézier form. In this paper the approximation is extended to B-Spline curves that generate near-conformal maps. It is then applied to approximating and animating ideal fluid flows. The B-spline curve underpins the design approach. With it an interface is developed to

Renker K. Weiss,Jelka Lavrih Sztajnbokpose two (2) discrete approaches for removing shape failures from such surfaces, without altering them more than is needed. The second approach is a simple Quadratic-Programming method, that is suitable for restoring the shape of almost shape-preserving tensor-product B-spline surfaces. The performa

These regions are defined for special types of curves called coils, which are non-strict versions of curves of geometric order three in three dimensions. We establish that the fill-in regions are a set of tetrahedra and show how they must be restricted to for

,Haben Kristalle magische Kr?fte?,software based on tensor-product patches, the particular scheme in [.] is expressed in terms of linearly-trimmed bicubic patches. Explicit formulas relating the coefficients of the patches to the vertices of an arbitrary input polyhedron are given. Four of these patches can be grouped together into
