| 摘 要： | 少数民族民居是中华民族文化的重要组成部分,而在现今民族大融合的背景下,传统少数民族建筑的传承和发展正呈现衰退之势,采用三维建模技术对少数民族民居进行数字化保存意义重大。苗族民居造型复杂,具有独特的吊脚楼结构,给规则建模带来困难。为此,本文以CityEngine软件为建模平台,巧妙地组合与运用挤出、拆分、平移等基础函数,编写了苗族民居底层支柱、二层主屋和歇山型屋顶的规则,完整地实现了苗族典型民居的规则建模,并实现了民居样式的动态调整与民族村寨的快速生成。研究结果表明,基于CGA规则对复杂的民族民居三维建模方法可行,为数字化保存少数民族民居提供了便捷的方式。

| Abstract: | Minority residence is an important part of the Chinese national culture .However, the inheritance and development of traditional minority architecture show a trend of decline under the current national amalgamation background .So, it is of great significance to carry on the digital preservation of the minority nationality dwellings with the 3D modeling technology .The Miao dwelling architecture is ingenious and complicated because it has a unique structure of the stilted building .This characteristic brings difficulty to rules modeling.Therefore,this study took CityEngine as the modeling platform ,and constructed the rules of the pillars of the first floor , the main house of the second floor and the Xieshan-style roof through intelligently combining the CGA functions of extrusion ,splitting, translation,etc.Finally,the rules based 3D model of the Miao typical buildings were implemented .With these rules,the residential style can be dynamically changed , and ethnic village can be rapidly generated .The results show that the 3D modeling method of complex ethnic houses based on CGA rules is feasible ,which provides a convenient way for the digital preservation of the minority residences . |
