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

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

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
