The article has designed a computer image generation system whichhas multilayer database. Dynamically loading data by pagination and time - sharing has generated a real time image which has big terrain scenery, different altitude and respective resolution. The contradiction between fidelity, texture internal memory and anti - muddle has been settled preferably.%设计了一种具有多层数据库的计算机图像生成系统。采用分页、分时动态加栽数据的方法,生成了大地景、不同高度具有相应分辨率的实时图像,较好地解决了逼真度、纹理内存、抗混迭和实时性之间的矛盾。
