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…
