Multi-Resolution Triangular Approximation of Terrains

Abstract—Presented in this paper is a procedure to generate multi-resolution models for a terrain height field. Although there have been many existing algorithms for simplifying geometric models, they cannot be applied to a height field, because most of them have been developed in the context of triangular meshes. An intuitive way is to apply existing algorithms after converting the height field into a triangular mesh. However, the conversion procedure requires an additional computational load as well as a large amount of memory as a general triangular mesh needs to maintain the topology information as well as the geometry information. To cope with the problems, we propose a procedure working directly on a height field. The proposed algorithm has been implemented and tested with various examples.

Index Terms—Height field, multi-resolution, quadric error metrics, simplification.
