| 摘 要： | 随着地学研究的不断深入,层状地层三维建模已成为研究的重点。基于格式化存储的多层DEM数据文件,将直接体绘制的思想融入到基于图像空间体绘制的经典算法—光线投射算法之中,提出基于多层DEM数据的光线投射算法。基于IDL和.NET的混合环境设计并实现了层状地层的三维可视化的平台。在该平台上,使用改进后的光线投射算法实现了层状地层的三维建模,以及对三维层状地质体的基本操作和基本地质信息的提取。

| Abstract: | With the deepening of geological science researches,stratified stratum 3-D modelling has been the research emphasis in this area.In this article,we focus on multilayer DEM data file based on formatted storage,merge the thought of direct volume rendering with image space volume rendering based classical algorithm — the ray casting algorithm,and propose the ray casting algorithm based on multilayer DEM data.Moreover,a 3-D visualised platform for stratified stratum has been set up and realised based on IDL and.NET hybrid environment.On the platform the improved ray casting algorithm is utilised to have achieved 3-D modelling for stratified stratum as well as basic operations on 3-D stratified geologic body and extraction of some basic geological information. |
