【摘要】 本文介绍了作者在将 OpenGL应用于三维地质模型可视化中的经验与体会。首先介绍了用 OpenGL显示三维地质模型的几个技术关键，包括模型绘制、投影变换、取景、 TIN表面显示、旋转、颜色与材质等。然后介绍了笔者基于 OpenGL的裁剪变换和缓冲区累加功能提出的“切片合成法”的原理、用途、应用注意事项和应用于煤田地质勘探中煤层底版等高线图制做的实例。更多还原

【Abstract】 This paper introduces experiences of author using OpenGL in 3D geological model visualization. Some key techniques of OpenGL displaying 3D geological model are discussed, including model drawing, projection translate, scene, TIN surface display, rotation, color and material and so on.On cutting transform function and buffer accumulate function of OpenGL, the author proposes a method, which is called "slice synthetic", to make contour line map and profile map in geology.更多还原
