A New Practical Approach forProcedurally RepresentingLofted Surface

Abstract

Abstract: Fitting a surface using geometric information (for example: an arbitrary set of 3D curves) is a useful method for comstructing complex surfaces. Tensor-product B-splines usually is used to constructe so-called lofted surfaces and most other types of surfaces in CAD, but several problems must be overcome if B-spline are to represent complex lofted surfaces[1]. We describe a practical approach by using an approximating Hermite type of surface, the construction of the surface is easy. Finally, a lofted surface model is given.
