【Abstract】 Bicubic B-spline surface interpolation is a widely used algorithm for free surface design in industry field. To meet the lack and demand for free surface design methods in space structures, an algorithm based on bicubic C~2 B-spline surface interpolation is presented in this paper. Examples appended to testify its feasibility and efficiency.更多还原
