Advanced visualization and modeling of tetrahedral meshes :

Abstract : Tetrahedral meshes are becoming more and more important for geo-modeling applications. The presented work introduces new algorithms for efficient visualization and modeling of tetrahedral meshes. Visualization consists of a generic framework that includes the extraction of geological information like stratigraphic columns, fault block boundaries, simultaneous co-rendering of different attributes and boolean operations of Constructive Solid Geometry with constant complexity. Modeling can be classified into geometric and implicit modeling. Geometric modeling addresses local mesh refinement to increase the numerical resolution of a given mesh. Implicit modeling covers the definition and manipulation of implicitly defined models. A new surface reconstruction method was developed to reconstruct complex, multi-valued surfaces from noisy and sparse data sets as they occur in geological applications. The surface can be bounded and may have discontinuities. Further, this work proposes a new and innovative algorithm for rapid editing of implicitly defined shapes like horizons based on the GeoChron parametrization. The editing is performed interactively on the 3d-volumetric model and geological constraints are respected automatically
