摘要/Abstract

摘要： 地质实体模型的三维可视化涉及到复杂地质体结构构造和相关地质属性数据的视觉表达与分析，利用科学计算可视化技术来充分、完整、交互式地展示与分析三维地质实体模型一直是三维地质建模领域的研究热点。研发的三维地质建模及可视化系统中可实现通用三维交互操作，包括三维模型的几何变换、三维交互定位与空间属性查询、三维模型的剖切、虚拟钻探、基坑开挖、隧道生成与虚拟漫游等。这些操作采用面向软件的技术，通过对现有的二维设备（如鼠标、键盘等）进行三维仿真，为全方位、多角度的认识和理解地质实体模型提供了强有力的支持。

Abstract: Visualization and analytical techniques for the solid models of geological entities are the intuitionistic, convenient approaches to express complicated geological structures and property parameters inside the geological body. In 3D geological modeling, it is one of the most important research fields that focus on visualization representation and analysis of the complicated geological data, interactive revelation and analysis for 3D geological models. This paper introduces the general operations for 3D-interaction of the solid models of geological entities. It expounds the interactive and analytical technique for the 3D geological model. It realizes several visual operations on 3D geological model including geometric transformation, spotting and the measurement of property value in any spatial position, slice up, virtual drilling, virtual roam, the excavation of foundation pit and tunnel. Those operations, which are based on software-oriented techniques, use 2D devices such as keyboard and mouse to the simulation of 3D spatial data, and will increase the comprehension of 3D geological model.

Key words: solid models of geological entities, 3D-interaction, visualization, 3D geological modeling, virtual reality
