| 摘 要： | 在阐述数字小区构建意义的基础上,结合MultiGen Creator专业建模软件和Vega可视化仿真应用软件,详细论述了构建三维数字小区的理论与实践,重点阐述了小区场景中对象的分类以及各自的建模理论,并对典型的两种实体在实践上的构建技术具体描述了其在Creator中的实现步骤,体现了该软件在建模方面显著节约面片的功能以及所建模型在Vega系统中实时顺畅显示的优越性。

| Abstract: | This paper base on the significance of constructing the digital district,combine the professional modeling software Multi- Gen Creator and visual application software Vega,detailed discuss the theoretic and practice of constructing the three-dimensional dig- ital district,expatiate on the classification of object in scenes and the modelling theory.Besides,character the fulfilling construction skills of the typical two entities realization process in Creator,embody the function of notably reduce space occupation in modeling and the su- periority of display smoothly in Vega. |
