Abstract. Nonnegative bivariate interpolants to scattered data are constructed using some C1 macro-element spline spaces. The methods are local, and rely on adjusting gradients at ...
Abstract. In this paper we introduce an unified framework for topological manipulation on triangulated 2manifolds with or without boundary. We show that there are two kinds of prim...
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...
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...
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 ...
