摘要
针对地学三维图绘制中问题,提出了设计思想,基于OpenGL在VC++环境下进行了实现,并用对应分析因子载荷三维图的实例来说明开发的三维图能清晰、准确、全面获取信息。旋转三维图的实现既能避免二维图缺乏整体感的缺点,又能避免有限角度观察三维图作结论可靠性差的缺点,为图元空间位置关系的分析提取提供了更高的真实性与方便性。
There are some very complicated problems in the 3D geologic graphing. The paper provides a design and means for solving them, and presents the codes of the 3D graph drawing based on OpenGL in Visual C＋＋. It is proved that the information can been clearly, exactly, and fully obtained with the example of the factor loading 3D graph drawing of the correspondence analysis. The results suggest that the revolving 3D graph can not only obviously excel both 2D dimension graph which presents from only an orientation, and 3D graph which presents from finite orientations, but also the implementation of it can discern the relative space places more properly and easily among different graph elements.
