for surface triangulations for the purpose of smooth surface fitting. The parametrizations, which are planar triangulations, are the solutions of linear systems based on convex combinations. A particular parametrization, called shape-preserving, is found to lead to visually smooth surface approximations.
The objective of the algorithm is to form a model of a surface. Data describing the surface includes the three-dimensional coordinates of points measured,.
