摘要
现实中,所有的物体都是三维的。但是在计算机中,所有的三维物体必须以二维平面图像的形式表现出来。将物体的三维坐标转换到计算机的像素位置,需要经过几何变换、投影变换、裁剪变换、视口变换等操作,才能正确显示出储层的三维图像。
In reality, all objects are three-dimensional. But in the computer, 3D object all must in the form of two-dimensional image performance. The three- dimensional coordinate conversion to the pixel location of the computer, need to operate through the geometric transformation and projection transformation, clipping transform and viewport transformation, in order to correctly display of 3D image of reservoir.
