【摘要】 在三维地震波动方程模拟或射线追踪正演研究与应用中,需要构建复杂的三维地震模型,因此,研究复杂地震模型的计算机建模方法是必要的。本文提出了采用基本几何形体及形体间的布尔运算来构建复杂模型的思想与方法,并在VTK可视化工具包和MFC开发平台的基础上,对该方法进行了算法与软件实现。应用设计的软件进行了建模实验,结果表明该方法用于地震建模是完全可行的,并大幅度地提高了地震建模的效率。更多还原

【Abstract】 The study of the complex seismic modeling method is necessary because the complex seismic model is needed in the research and application on 3D seismic wave equation simulation or the 3D ray tracing simulation.A method that uses basic geometric shapes and their Boolean operations to build complex seismic model is proposed and both algorithm and software are implemented based on visualization toolkit(VTK)and MFC development platform.The modeling tests by using the software we designed show that this method is feasible to be used in the seismic modeling and in addition,the efficiency of seismic modeling is widely improved.更多还原
