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 ...
Control Points for Multivariate B-Spline Surfaces over Arbitrary Triangulations
(Blackwell Science Ltd and the Eurographics Association, 1991)
This paper describes first results of a test implementation that implements the new multivariate B-splines as recently developed by Dahmen et al. 10for quadratics and cubics. The surface scheme is based on blending functions ...
Using Subdivision on Hierarchical Data to Reconstruct Radiosity Distribution
(Blackwell Publishers Ltd and the Eurographics Association, 1997)
Computing global illumination by finite element techniques usually generates a piecewise constant approximation of the radiosity distribution on surfaces. Directly displaying such scenes generates artefacts due to ...
