摘　　要：角点网格模型是实现不同区块不同尺度三峡库区滑坡体模拟的关键。从介绍角点网格模型的特点入手,介绍如何利用Open Inventor实现以角点网格模型表达的三维地层的可视化显示。重点介绍了如何利用角点网格模型来表达多尺度地质灾害体的三维地层构造格架。同时研究了用三维地层体数据中各角点网格体的属性信息进行可视化表达的方法,实现了基于角点网格模型的多尺度三维地层的空间信息和属性信息多重可视化。Corner-point grid model is the key to realize landslide simulation of different scales and blocks in Three Gorges Reservoir Areas.In the view of corner-point grid model,we describe visualization of 3D stratum based on expression of corner-point grid model by using Open Inventor.And,we focused on illustrating the tectonic-stratigraphic framework of 3D stratum of multi-scale geological disaster mass using corner-point grid model.Meanwhile,the visualization of attribute information of each corner-point grid unit in 3D stratum data is discussed.We realized the visualization of spatial information and attribute information of 3D stratum based on the multi-scale corner-point grid model.
