摘　　要：给出了一种基于MultiGenCreator的城市仿真中地形的快速构建方法,分析了虚拟城市中地形的特点,阐述了快速构建方法的原理,对方法实现过程中的纹理映射、模型优化等几个具体问题进行了分析并给出了解决办法,文章最后则给出了实验结果和进一步的研究方向。实践表明,该方法可以大大提高城市仿真中的建模速度,从而减少城市仿真产品的生产成本。This paper presents a rapid modeling method based on Multigen Creator. The characteristics of the landform in urban simulation are analysed and the basic principle of the rapid method is introduced. Several detailed problem, such as texture mapping and model optimization, appeared during the implementation course are resolved. In the end, the experiment results as well as the possible future work are discussed. Practice shows that the rapid method can raise the efficiency and speed of modeling of virtual scene, thus reduce the production cost of the product of urban simulation.
