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 ...
