基于IDL的三维地质动态建模

三维地质建模凭借着形象直观、操作简单、功能丰富的优势，广泛应用于地质、矿产、工程等领域。在讨论表面建模与实体建模方法的基础上，开发程序探索了其在交互式数据语言（IDL）平台上的实现过程，并初步建立了可以应用于滑坡、泥石流、地面沉降等动态过程展示的算法。最后以煤田与泥石流模型的构建与可视化作为实例进行了效果验证。经测试，IDL可以较好地完成三维地质建模任务，并且在插值、剖分等方面表现了自己的优势，为工程地质信息化的实现提供了一种思路。 

3D geological dynamic modeling based on IDL

With the advantages of intuitive image, simple operation and rich function, the visualization technology of 3D geological model is widely used in geology, minerals, engineering and other fields. After summarizing the features of surface modeling and voxel modeling method, this paper explores the implementation on IDL platform by developing application. In addition, the simulation ability of dynamic processes, which is suitable for displaying landslide, debris flow, land subsidence and the like was achieved. Finally, the model construction and visualization of a coal field and debris flow were taken as examples to verify the effectiveness. Through testing, IDL can complete 3D geological modeling task well, and shows its own advantages in interpolation and segmentation, which provides a way for the realization of engineering geological information.
