Spherical quadratic Bézier triangles with chord length parameterization and tripolar coordinates in space
We consider special rational triangular Bézier surfaces of degree two on the sphere in standard form and show that these surfaces are parameterized by chord to the patch vertices and the ratios of the dist...

On Computing Approximate Parameterizations Of Algebraic Surfaces
In this paper we present a novel approach which can be used for computing approximate parameterizations of algebraic surfaces. The algorithm is based on determining the topological graph of a given surface and replacing its tria...
