On the implementation of discrete exterior calculus

摘要

In this article, we present the development of Java library implementing Discrete Exterior Calculus (DEC) constructs using the Processing IDE rendering environment to analyze WaveFront .obj objects. The library contains common DEC structures and operators found in other implementations and provides local iterators to explore the topological relations that DEC theory relies on, along with classes able to render both vector and scalar fields using the Processing IDE capabilities.
