Fitting Triangular B-Splines to Functional Scattered Data
(Blackwell Science Ltd and the Eurographics Association, 1996)
Scattered data is, by definition, irregularly spaced. Uniform surface schemes are not well adapted to the locally varying nature of such data. Conversely, Triangular B-Spline surfaces 2 are more flexible in that they can ...
Spherical Triangular B-splines with Application to Data Fitting
(Blackwell Science Ltd and the Eurographics Association, 1995)
Triangular B-splines surfaces are a tool for representing arbitrary piecewise polynomial surfaces over planar triangulations, while automatically maintaining continuity properties across patch boundaries. Recently, Alfeld ...
