Abstract
3D stratum modeling and its cutting algorithm is one of the hotspot in the field of 3D geological simulation. For the constructing demand of the 3D digital stratum, proposed a 3D mixed data model that composed by Multi-DEM and TEN models. The model uses the Multi-DEM to express the simple, regular, laminar 3D geologic body, uses TEN structure to express the complex, non-laminar geologic body, and then forms the 3D stratum model that has the coincident models and the uniform logic, and meets the need of the stratum 3D attributes calculation and 3D spatial analysis. Based on the mixed model DEMs-TEN, use the cutting plane to slice the stratum reconstruction model, and generate edges sequence and points sequence on the cutting plane, and then generate a closed contour by edges sequence and points sequence and determine included relation among the contour lines. Therefore with the above methods, carry Delaunay triangulation on closed contour, thus get a whole profile model. The slice sample indicates: the cutting algorithm has high rate.
