Abstract

In this paper we describe an implementation of the isotropic red-green refinement technique for two-dimensional triangulations as described in [1] and [5]. In addition, we present a new method for local recoarsening of a previously refined mesh. Furthermore, we explain some techniques to interpolate data while manipulating a grid.
