Abstract
Structured grids like Cartesian or stratigraphic grids are state-of-the-art for
three dimensional modeling of the subsurface and a set of advanced
visualization and modeling tools are available for these types of
grids. However, tetrahedral meshes are becoming more and more
important for geo-modeling applications since they can conform to
complex geometries and provide more flexibility in terms of mesh
resolution. Therefore, techniques for visualizing and modeling
tetrahedral meshes need to be developed. Geological models are rich
in information of different nature like topology of fault blocks,
geological properties, geophysical data (e.g. seismic),
stratigraphic layers or distances to geological interfaces like
faults or to artifacts (e.g. wells). For an optimal interpretation,
these layers of information can be combined into a single image
using multi-texture capabilities of modern graphics hardware. An
image consists of a set of user-defined iso-value surfaces and
crosssections. Boolean operations of Constructive Solid Geometry
with constant complexity are directly performed on the graphics
hardware and allow complex geological and geometrical conditional
queries. The computation and rendering of the iso-value surfaces is
performed in real time on models with up to several hundred thousand
cells on normal consumer hardware.
