摘要
以三维城市高层建筑模型为研究对象,基于3DS Max二次开发工具探讨了自动分层切割技术,实现了批量自动切割处理,满足三维空间分析在城市规划、房屋管理、公安消防等方面具体的细节需求,丰富了3D GIS的拓展应用。该文简要介绍了CSG模型、三维建筑模型抽象描述、三维模型纹理、三维模型分割以及碰撞检测的定义,提供了完整的技术路线和解决办法,提出了基于3DS Max的切割算法,并通过实例验证了切割方法的正确性和实用性,具有一定的实践价值。
The research object of 3D City high-rise building model, based on Max 3DS secondary development tool,the automatic slicing technique is discussed. Automatic cutting implements batch processing,and fulfill the need of the 3D spatial analysis in urban planning,housing management,public security fire control the details of the specific requirements. Enrich the expanding application of 3D GIS.This paper briefly introduces the CSG model, 3D building model abstract description, 3D model texture,3D model segmentation and the definition of the collision detection. Provides a complete technical route and the solution,cut algorithm is proposed based on 3DS Max,and through the example verifies the correctness and practicability of the cutting method,has a certain practical value.
