Application of Vector Shear Technology in 3D Geological Modeling

3D geological modeling is the key to 3D geological simulation and visualization software system.This paper studies the theory and algorithm of BSP tree-based Vector Shear,and raises a method which uses Vector shear to quickly build complex geological modeling and visually displays the inner information of geological bodies.In the end,it takes the example of geological digital engineering and 3D stratum analysis,and draws a conclusion that the algorithm is efficient and practical.
