Building 3D geological surfaces from field data using implicit surfaces

 abstract = { We present a method to build 3D geological horizons from sparse field data using implicit
functions on tetrahedral meshes. The proposed technique accounts for typical types of field data:
position and possibly orientation of horizons measured on the topographic surface, orientations measured
within layers, fold axial surface and fold axis plunge. All types of data are recast as Discrete
Smooth Interpolation constraints for a potential field on a tetrahedral mesh. In the current implementation,
faults are accounted for by introducing topological discontinuities in the tetrahedral
mesh before modeling horizons. Because an automatic solution is always questionable, interactive
editing tools introduced by Frank and Mallet [2005] can be used for expert editing of the horizon
geometry. The method is illustrated on the Sanguiniere depocenter in the Annot turbiditic
formation, SE France. },
