Efficient Subdivision of Bézier Curves/Surfaces via Blossoms
Krassimira Vlachkova
We consider the problem of Bézier curves/surfaces subdivision using blossoms. We propose closed-form formulae for blossoms evaluation, as needed for the calculation of control poin…
Testing tensor product Bézier surfaces for coincidence: A comprehensive solution
Krassimira Vlachkova
It is known that Bézier curves and surfaces may have multiple representations by different control polygons. The polygons may have different number of control points and may even b…
Edge convex smooth interpolation curve networks with minimum -norm of the second derivative
Krassimira Vlachkova
We consider the extremal problem of interpolation of convex scattered data in by smooth edge convex curve networks with minimal -norm of the second derivative f…
Interpolation of scattered data in using minimum -norm networks,
Krassimira Vlachkova
We consider the extremal problem of interpolation of scattered data in by smooth curve networks with minimal -norm of the second derivative for . Th…
Bi-quartic parametric polynomial minimal surfaces
Ognian Kassabov, Krassimira Vlachkova
Minimal surfaces with isothermal parameters admitting Bézier representation were studied by Cosin and Monterde. They showed that, up to an affine transformation, the Enneper surfac…
