摘要:Abstract(#br)We propose a method for computing the Minkowski sum of two free-form surfaces, given in a tensor product B-spline representation in R 3 . The Minkowski sum (typically a three dimensional volume), is represented by its boundary surface(s), also referred to as the enve...

摘要:Abstract(#br)We present a subdivision based algorithm to compute the solution of an under-constrained piecewise polynomial system of n − 2 equations with n unknowns, exploiting properties of B-spline basis functions. The solution of such systems is, typically, a two-manifold...

摘要:Abstract(#br)We propose a general scheme for detecting critical locations (of dimension zero) of piecewise polynomial multivariate equation systems. Our approach generalizes previously known methods for locating tangency events or self-intersections, in contexts such as surf...

摘要:Abstract(#br)Given a three dimensional object B ⊂ R 3 , the visual hull of B (a concept introduced by Laurentini in 1992) is the smallest set V B ⊂ R 3 containing B with the following property: for each point p on the boundary of V B there exists a direction from which p is ...
