Clough tocher interpolation
WebAug 18, 2011 · Clough-Tocher interpolation. This specific interpolation technique was developed by Clough and Tocher in 1965 . It can be applied on each triangle in a triangulated grid to generate a surface over the entire domain. First, each triangle is divided into three sub-triangles by joining each vertex to the centroid of the triangle. WebFeb 1, 1999 · Cubic precision Clough-Tocher interpolation. ☆. The standard Clough-Tocher split-domain scheme constructs a surface element with quadratic precision. In this paper, I will look at methods for improving the degrees of freedom in Clough-Tocher schemes. In particular, I will discuss modifications to the cross-boundary construction …

We present a methodfor scattered data interpolation that is based on the … Webspline functions over a 3D Clough-Tocher re nement of a tetrahedral par-tition 4. The scheme produces spline interpolants which are globally C1 over 1while C2 around the vertices and C around the edges of 4. A fur-ther generalization of the Clough-Tocher re nement enables Worsey and Farin in [7] to construct interpolation by C1 cubic splines ...
