基于Three.js的矿区三维地质模型可视化

3D Geological Model Visualization of Mining Areas Based on Three.js

摘要: 三维地质可视化是矿区资源勘探、规划设计与安全监测的核心技术支撑，传统可视化方案常受限于插件依赖、跨平台兼容性差及交互体验不足等问题。针对矿区地质模型的高效展示与交互需求，本文提出一种基于Three.js引擎的三维地质可视化方案。首先通过AutoCAD提取矿区地层剖面线，获取地层界面、岩性边界等关键几何信息；随后将剖面线数据导入GoCAD软件，构建包含多套地层、矿体及地质构造的三维地质模型；最后通过模型格式适配与Three.js引擎加载，实现了矿区三维地质模型的无插件Web端可视化与交互式浏览。实验结果表明，该方案充分发挥了Three.js免插件、跨平台、硬件加速的技术优势，可视化模型几何精度高、纹理效果真实，支持旋转、缩放、平移、地层信息查询等流畅交互操作，为矿区地质信息的共享与分析提供了便捷高效的技术手段，具有重要的工程应用价值。

Abstract: 3D geological visualization serves as a core technical support for resource exploration, planning and design, and safety monitoring in mining areas. However, traditional visualization solutions are often constrained by issues such as plugin dependencies, poor cross-platform compatibility, and inadequate interactive experiences. To address the requirements for the efficient display and interaction of geological models in mining areas, this paper proposes a 3D geological visualization scheme based on the Three.js engine. Firstly, stratigraphic profile lines of the mining area are extracted using AutoCAD to obtain key geometric information such as stratigraphic interfaces and lithological boundaries. Subsequently, the profile line data is imported into GoCAD software to construct a 3D geological model comprising multiple stratigraphic layers, ore bodies, and geological structures. Finally, through model format adaptation and loading via the Three.js engine, plugin-free Web-based visualization and interactive browsing of the 3D geological model are realized. Experimental results demonstrate that this scheme fully leverages the technical advantages of Three.js, including its plugin-free nature, cross-platform compatibility, and hardware acceleration. The visualized model exhibits high geometric precision and realistic texture effects, supporting smooth interactive operations such as rotation, zooming, panning, and stratigraphic information querying. This provides a convenient and efficient technical means for the sharing and analysis of geological information in mining areas and holds significant engineering application value.
