A Tutorial for Designing Flexible Geometric Algorithms
The implementation of an algorithm is faced with the issues efficiency, flexibility, and ease-of-use. In this paper, we suggest a design concept that greatly increases the flexibility of an implementation without sacrificing ease-of-use and efficiency. We demonstrate the advantages of our concept through a C++ implementation of a simple rectangleintersection algorithm, which follows the well-known sweep-line paradigm. We lead the reader, who should be familiar with C++ and its template mechanism, from a naive interface in a step-by-step guide to an interface offering full flexibility. The gain in flexibility can reduce the overall implementation effort by facilitating code reuse. Reusability in turn helps to achieve correctness simply because more users mean more testing. Though most of the ingredients of our concept have already been suggested elsewhere, to our knowledge this is the first time that they are applied vigorously in a geometric setting. We include a thorough experimental...
