摘　　要：构建了“数字矿山”三维可视化框架模型,主要分为数据操纵、映射和绘制三个子过程。设计了“数字矿山”可视化系统模型,以集成式混合策略为基础,根据不同的应用目分别采用互补式和转换式混合策略。将体视化技术引入“数字矿山”三维可视化领域,针对“数字矿山”实体对象的不同特征和构模方式建立了光线投射方法、MarchingCubes方法和基于OpengGL技术几何绘制方法的适用条件并进行了实例验证,取得了逼真的效果。The 3D visualization framework model includes three main processes: data processing, mapping and rendering. Based on integrative mixed strategy, the digital mine visualization systemic model used complementary mixed strategy and used converted mixed strategy accord to the different application. The volume visualization and their applications were studied to the field of digital mine 3D visualization, and the applicable different rendering methods were proposed including ray casting, marching cubes and OpengGL-based geometrical rendering technology aiming to the mining entity characteristic and application. The technique was used to a Chinese iron mine, depicting a simulated true picture of the mining entity.
