摘　　要：探讨利用开放图形库OpenGL实现三维地层显示的途径;讨论三维地层层面构造的插值基本原理;提出了地层的任意方向切割方法,即适用于水平截面和斜截面的网格分割法和适用于竖直截面的交线分割法。将此三维地层切割方法应用于广东省大型水利工程———东深供水改造工程中,实现了三维地层的任意切割,验证了该方法的可靠性和实用性。This paper investigated a new approach to realize the 3-dimensional by using the OpenGL, discussed the interpolation principle for 3-dimensional ground strata cutting. Two strata cutting methods were suggested, the grid cutting method to be used for horizontal and sloped sections, and the intersection line cutting method for vertical sections. Finally, practicability of the method was illustrated by its application on the reconstruction project of water supply for Shenzhen from Dongjiang in Guangdong Province.
