计算机三维技术的应用领域越来越广泛。现已广泛地应用在影视、广告、动画、网络、游戏等各个领域。3D技术在公路行业的应用,是在现有的公路、桥梁、互通立交等设计方法的基础上,提出了三堆建模的思路。互通立体交叉设计作为一个复杂的系统工程,它涉及到很多方面,同时也涵盖道路、桥梁、交通、管线、照明、绿化等专业,一旦建成,不易改建,所以方案的确定是非常重要的,互通立交方案的3D效果设计就为立交选型提供了一个非常直观的效果。3D效果的立交模型对立交方案的选型、设计研究及线型的优化具有非常重要的作用和意义。给出了三堆建模的方法和流程,并利用AUTOCAD、3DMAX、PHOTOSHOP等软件,制作出三堆效果图及动画效果,从而以更直观的形式为方案设计及景观分析提供了有利条件。
The application of computer 3D technology is more and more widely used. Has been widely used in television, advertising, animation, network, games and other fields. The application of 3D technology in the highway industry is based on the existing design methods of road, bridge, interchange and so on, and puts forward the idea of three-pile modeling. As a complicated system engineering, it involves many aspects and also covers roads, bridges, traffic, pipelines, lighting, afforestation and other majors. Once built, it is not easy to rebuild, so the plan is very important. Interworking The 3D effect design of the interchange offers a very intuitive effect for the interchange selection. The 3D effect of the interchange model of the program of interchange selection design, design research and linear optimization has a very important role and significance. The method and process of three-pile modeling are given. With the software of AUTOCAD, 3DMAX, PHOTOSHOP and so on, three-pile renderings and animation effects are produced, which provides more favorable conditions for the scheme design and landscape analysis in a more intuitive way.
