Topological Co-refinement : A swiss army knife for geomodeling (continued)

@inproceedings{ConreauxRM2001,
 abstract = { In geomodeling, several tasks require 2D or 3D meshes to be intersected. The notion of ’corefinement’ is an operator acting on cellular meshes, and enabling different operations to be implemented in a robust, unified and theoretically sound way. For instance, modeling a fault intersecting an horizon requires to compute accurate intersections between triangles, and remeshing both surfaces (this corresponds to the ’Cut’ operation in Gocad). Another case is encountered when constructing polyhedral grids made of multiple blocks. Suppose that two blocks are separated by a fault. For such a grid, in order to ease flow simulations ran on it, it may be suitable to accurately represent the geometric relations between the cells in contact with the fault. The last case may be illustrated by several unstructured grids representing intersecting channels. These channels may be combined into a single grid by using the so-called ’boolean’ operations. This paper reviews several approaches for co-refinement for surfaces and volumes, and shows how they can be used for geomodeling. },
