摘　　要：分析了将Creator应用于虚拟城市三维建模的技术路线,讨论了建模过程中的三个关键技术,解决了虚拟城市三维建模中精细程度和数据量之间的矛盾,并结合实践加以应用。It analyzes the technique routine of 3D modeling about virtual city through Multigen Creator. And it, especially, discusses the three key techniques in the process of building models, that is, LOD, texture with alpha path, and instance. Based on the practice, it solves the conflict between level amount and data.
