Skinning of circles and spheres
Skinning of an ordered set of discrete circles is discussed in this paper. By skinning we mean the geometric construction of two G1 continuous curves touching each of the circles ...

Precise Hausdorff distance computation between polygonal meshes
We present an exact algorithm for computing the precise Hausdorff distance between two general polyhedra represented as triangular meshes. The locus of candidate points, events wh...

Simplicial diffeomorphisms
In this paper we introduce a new framework for geometric modeling that combines implicit and parametric surface representations with volumetric warpings. The framework is based on...

Topology of 2D and 3D rational curves
In this paper we present algorithms for computing the topology of planar and space rational curves defined by a parametrization. The algorithms given here work directly with the p...

On rational Minkowski Pythagorean hodograph curves
Minkowski Pythagorean hodograph curves are polynomial curves with polynomial speed, measured with respect to Minkowski norm. Curves of this special class are particularly well sui...

A kinematic approach to Kokotsakis meshes
A Kokotsakis mesh is a polyhedral structure consisting of an n-sided central polygon P0 surrounded by a belt of polygons in the following way: Each side ai of P0 is shared by an a...

Construction and smoothing of triangular Coons patches with geodesic boundary curves
Given three regular space curves r1(t), r2(t) r3(t), t [ 0, 1 ] that define a curvilinear triangle, we consider the problem of constructing a C2 triangular surface patch R(u1, u2...
