Webamines the suitability of triangle-based Coons patches and Clough-Tocher Bézier splines for terrain modelling. The basic idea of Coons patches is to specify a network of boundary curves and to find a surface which passes through these curves. Clough-Tocher Bézier splines, in contrast, use control points to describe the shape of the surface. WebJan 1, 2004 · In a similar way one can check that the method based on the Clough-Tocher macro-element can exactly reproduce any nonnegative linear polynomial, but not all quadratic or cubic polynomials. Remark 8. WebBy subdividing each n -simplex in an appropriate way, we show how to solve the interpolation problem using piecewise cubic polynomials. The subdivision process is the key to the method and is inductive in nature. It is systematically built up from the two-dimensional case where a variant of the well-known Clough-Tocher element is used. the poster guy vancouver
