λ、μ-B样条上可展曲面的几何设计
Geometric design of λ、μ-B spline developable surface
摘要
Abstract
Two direct and simple design methods of developable surface are developed based on the duality of the mid-point of 3D projective space and the plane.The method makes the developable surface expressed by the control plane of blending function.A new piecewise polynomial spline curve with two local shape parameters λ and μ is defined by this blending function.Therefore the new developable surface has tunability of flexible local shape and more strong description ability,and increases degree of freedom of the modeling.A class of developable surface is obtained by regulating the parameters λ and μ and the class of developable surface keeps characteristics of B-spline surface,that is uniform B-spline surface is formed by special value of λ and μ.This provides a new method for the design of the surface.关键词
