A Framework for Triangular Mesh Generation and Modification Processes

In this paper we present an object-oriented framework for implementing mesh generation and mesh modification processes. We have modeled the framework using Design Patterns, which exploit the benefits of reuse and provides an environment where new components can be easily developed. Examples of the application of the framework are presented: 2D Delaunay refinements, 2D Bisection Refinements, and terrain approximation. The framework has been implemented in C++ using the Qt libraries for creating a graphical interface.
