This paper presents a symbolic approach to the computation of blend surfaces across piecewise polynomial and rational surfaces. Curves in the parameter space of the primary surfaces can be specified as the rail curves, also known as trimlines, of the blend. Several techniques which require various l

✦ Synopsis
Given a convex lattice polygon, we compute a descending sequence of lattice polygons obtained by repeatedly passing to the convex hull of the interior lattice points. This process gives the idea for an algorithm that simplifies a given parametric surface by reparametrization.

AbstractÐThis paper discussed the problem of ®nding intersections between surfaces. Surfaces are divided into planar sub-patches, typically triangles. Triangles of one surface are tested for intersection with triangles of the second surface, one by one. The triangles are ®rst projected on a horizont
The purpose of the paper is determination of singularities of an envelope to a family of parametric surfaces. The authors propose a simplified solution to this problem based on consideration of the surface of action that is formed by the lines of tangency of the envelope and the generating surface o
