Dupin cyclide blends between non-natural quadrics of revolution and concrete shape modeling applications
A general algorithm for the blending of 3D non-natural quadrics of revolution. Two Dupin cyclide patches and an intermediate cylinder are used for the blending. The 3D blending is reduced to a 2D direct computation of two cyclide patches. Several examples of algebraic and non-algebraic surface blendings are presented. Two complete shape modeling applications for designing concrete objects are provided.
