| 摘 要： | 人机交互是可视化系统中不可缺少的组成部分，三维交互的技术关键是建立屏幕二维坐标与三维空间坐标的对应关系．基于改进三棱柱3D地质模型，在其可视化过程中采用几何变换方法，并借鉴OpenGL的选择、反馈等技术，实现了矿床地质模型的直接三维交互操作，提高了3D地质建模软件的易用性与灵活性．

| Abstract: | The man-machine interaction is an indispensable part of visualization system. The key technique of 3D interaction is to find the relation between 2D coordinate of computer screen and the spatial 3D coordinate. This paper realizes the direct 3D interaction operation in visual deposit geological modeling based on the improved triangular prism 3D geologic model and by using geometric transform method and the techniques of choice and feedback of OpenGL, which increases the usability and agility of the system. |
