Simplification of thin features in structural models

in: Proc. 32nd Gocad Meeting

Abstract

We propose a method to simplify 3D structural models, i.e. volumetric models defined by their boundary surfaces (faults, horizons, detachments, etc.). The goal is to obtain a model where thin layers are replaced by surfaces and low angle contacts are minimized. The method is founded on a sampling of the boundary surfaces by a set of points whose positions are optimized with a Centroidal Voronoi Tessellation. We consider the intersections of the Voronoi diagram of these points with the model to compute the simplifed nal model. The method is applied on structural models with several thin layers, tangential contacts and shows its potential to ease volumetric grid generation.
