Geometric construction of spline curves with tension properties
In this paper a class of C(2) boolean AND F C(3) spline curves possessing tension properties is described. These curves can be constructed using a simple modification of the well-known geometric construction of C(4) quintic splines; therefore their shape can be easily controlled using the control net. Their applications in approximation and interpolation of spatial data will be discussed. (C) 2003 Elsevier B.V. All rights reserved.
