Kang, Baosheng; Ma, Xiang; Zhou, Rurong On the representation of revolution surface and sphere by NURBS polynomial. (Chinese. English summary) Zbl 0808.68111 J. Nanjing Univ. Aeronaut. Astronaut. 26, No. 1, 80-87 (1994). Summary: This article discusses the NURBS representation of revolution surfaces and spheres. For the construction of revolution surfaces, the general formula for determining control vertices and weights are given. By means of the stereographic projection, the paper presents the non-degenerate parametrically rational polynomial representation of sphere.
