地质构造三维可视化模型探讨

STUDY ON THE 3D VISUAL MODEL OF GEOLOGICAL STRUCTURE

地质构造的三维可视化技术包括数学建模和可视化显示两方面。建立地质构造三维可视化模型的典型方法包括三维规则网格法、TIN表面法、四面体法以及综合法。针对地质构造模型中断层处理的特殊性 ,提出了基于TIN表面法的局部法和整体法两种处理技术。将地质构造三维模型的可视性归纳为 5种方式。

The 3D visual technique of geological structure consists of two parts, mathematical modeling and visual display. The typical 3D visually modeling methods of geological structure include the 3D regular network model, the TIN surface model,the tetrahedron elements model and the integration model. Two methods, partial treat method and integral treat method based on the TIN surface model, have been presented to deal with the special problems involving fault. Five methods of 3D visually modeling of geological structure have been divided and discussed.
