(English Abstract)
The Hausdorff distance between two objects can be used as a measure for their similarity, but its precise computation is a significantly challenging problem that is as complex as the objects are similar, since it is more difficult to locate where the Hausdorff distance occurs. In this paper, we solve this obstacle and present an algorithm that precisely computes the Hausdorff distance between a triangle mesh model and a quad mesh model. We narrow down where the Hausdorff distance occurs by iteratively partitioning the models into smaller pieces and removing irrelevant ones. The ¡°match¡± that we set for each piece and its corresponding upper bound for the Hausdorff distance enable us to decide whether to keep the piece. The Hausdorff distance thus computed can be used to evaluate quad meshes that approximate triangle meshes.
