3D Visualization Modeling and Application of Global Crustal Structure Data
全球地壳结构数据的三维可视化建模与应用

It is of significance to represent crustal structure and simulate the propagation of seismic wave in crust and mantle with visualization technique for interpreting seismic events efficiently. Based on analysis for improved CRUSTS. 1 global crustal structure data, the visualization modeling method of combining cuboids with quad-prism is presented, and the visualization model of global crustal structure data is also established with OpenGL modeling techniques. Fur therrnore, the three-dimension representing of CRUSTS. 1 crustal structure data, the viewing from different directions and the cutting alone an arbitrary plane have been implemented in Delphi with OpenGL.
