3D Sealed Geological Block Modeling with Wire Frame Component

HOU Wei-sheng1,2,WU Xin-cai1,LIU Xiu-guo11.Faculty of Information Engineering,China University of Geosciences,Wuhan 430074,China2.Department of Earth Sciences,Sun Yat-sen University,Guangzhou 510275,China  
To construct 3D geological blocks with the topology of spatial data model,the notion of wire frame component describing the outline of simple block is presented to organize the topology of elements in the 3D geological model.With the help of the notion,an automatic block identification approach is proposed,in which the directed edge and directed triangle are used as basic search unit.The simulation result illustrated that the approach presented not only can model complex blocks,but also can exactly represent the topology among the elements in the block and local geological phenomena such as small fault (free face).The method provides base of the application of 3D geology model to seismic forward modeling,ray tracing,etc.
