Constant-radius blending in surface modelling

Computing the Surface Area of Three-Dimensional Scanned Human Data

“…Depending on the number of surfaces to be blended, various approaches have been proposed. Choi and Ju [13] used a rolling ball to generate a tubular surface with G 1 -continuous contact to the adjacent surfaces. This technique can be made more flexible by varying the radius of the ball [14].…”

Computational Methods for Geometric Processing. Applications to Industry

“…To this aim, a number of methods are described, from interactive methods [4,56] to automatic methods based on calculation of intersections of offset surfaces to the two given surfaces [46,56]. Blending of tensor product B-spline or Bézier surfaces (see [18,20,34] for a definition) are analyzed, for example, in [4,12,24,45]. See also [86] for blending algebraic patches and [28,66] for implicit surfaces.…”
