摘要
描述了体视化技术的主要过程。对地矿工程的两种 数据,即离散的钻孔采样数据和连续的工程布置几何模型数 据,分别通过插值处理和体素化处理形成三维规则体数据 场。最后,通过对体视化的各种算法和地矿工程数据的特点 进行了剖析,给出了一种改进的光线投射法,并结合某一铁 矿山的情况进行了模型验证。
In this paper, the main process of volume visualization technique is introduced. Then, the two types of data, that is, discrete geological drill-core data and consecutive mining engineering design data ,are processed into 3D regular volume data by interpolation method and voxelization method. Based on analyzing the characteristics of various volume visualization algorithms and geological or mining engineering data, a modified ray casting method is proposed for the visualization of geological and mineral data. Finally, the improved ray casting method was used to visualize the ore body of an iron mine in China.
