A Rapid Modeling Algorithm of Block Model from Complex Ore-body
Block Model,which is suitable for expressing non-uniform distributed Body Model,is one of the most important expression and calculation model for orebody.It is widely applied in 3D Geophysical Inversion,exploration and Mineral Assessment,etc.Currently,the general method of Block Modeling of complex orebody is to convert the Surface Model of an orebody to its Block Model.However,there are two key problems during the general process.One is numerical Intersections Calculation between triangles and cuboids(≥106).The other is search of internal cuboids in complex orebody.In order to deal with the problems,the paper put forward a rapid Block-Modeling algorithm from complex orebody by applying Uniform Mesh Segmentation and Flood-fill algorithms,whose time complexity is O(n).It is creative for applying tow-dimension Flood-fill algorithm idea to construct 3D Block Model.Besides,the algorithm is suitable for constructing Block Model from Arbitrary Surface in 3D.At the end of the paper,the Time Complexity Analysis and experiment are carried out and the result shows that the method is efficiency and general.
