We consider the Multi-Triangulation, a general model for representing surfaces at variable based on triangle meshes. We analyse characteristics of the model that make it effective for supporting basic operations such as extraction of a surface approximation, and point location. An interruptible algorithm for extracting a representation at a resolution variable over the surface is presented. Different heuristics for binding the model are considered and compared. Results on both construction and the extraction algorithm are presented.

Abstract
We consider the Multi-Triangulation, a general model for representing surfaces at variable based on triangle meshes. We analyse characteristics of the model that make it effective for supporting basic operations such as extraction of a surface approximation, and point location. An interruptible algorithm for extracting a representation at a resolution variable over the surface is presented. Different heuristics for binding the model are considered and compared. Results on both construction and the extraction algorithm are presented.
