Triangle-based multi-resolution models for height fields

Abstract

Large-size data sets describing height fields (e.g., terrains) can be handled with multi-resolution models. We analyze and compare two multi-resolution models for height fields based on regular and irregular triangle meshes, respectively. Our comparison takes into account the space required by the data structures and the effectiveness in extracting variable-resolution surface representations.
