【摘要】：随着经济的快速发展,居民对居住条件有了更高的标准与要求,太阳光照作为考查住宅舒适度的主要因素之一逐渐被人们关注,因为采光权引起的纠纷也日渐增多。此外,日照分析报告也是建筑竣工验收的必要提交材料之一。于是对具有日照分析功能的软件的需求迅速增长。由于分析方法本身的适用性与局限性,传统的手工日照分析方法与基于CAD的二维日照分析方法已逐渐不适用于目前各式各样建筑物的日照分析。在三维可视化与建模技术快速发展的背景下,将三维技术与日照分析结合起来开发出三维日照分析系统已经成为可能。本文基于此点,对建筑三维可视化日照分析系统进行研究,并完成了三维日照分析系统的设计与实现。本论文的主要工作与成果如下:(1)在分析了相关坐标系与时间系统后,确定了反映太阳运行轨迹的日照参数及计算模型。(2)在总结了棒影日照图法、二维CAD分析法、圆锥曲面法的优缺点后,本文提出了基于起伏地形的阴影分析方法,解决了在地表起伏条件下阴影发生形变的状况,并提出了改正算法。(3)通过对多种三维建模方法进行实验,确定了以二维CAD设计图为底图导入SketchUp进行建模的方法,并将此方法作为本文三维日照分析系统建模的主要手段。对Unity3D可视化平台的各个要素也进行了三维可视化实验。(4)基于Unity3D三维可视化平台,论文设计了建筑可视化三维日照分析系统,实现了第一视角浏览与漫游、日照计算、阴影分析等功能。实地采集了日照数据,并对系统计算精度加以验证。
[Abstract]:With the rapid development of economy, residents have higher standards and requirements for the living conditions. As one of the main factors in the study of residential comfort, solar light has gradually been paid attention to, because the disputes caused by lighting rights are also increasing day by day. In addition, the Rizhao Analysis report is also one of the necessary submissions for construction completion acceptance. As a result, the demand for software with sunshine analysis grew rapidly. Because of the applicability and limitation of the analysis method, the traditional manual sunshine analysis method and the two-dimensional sunlight analysis method based on CAD are not suitable for the sunshine analysis of various buildings. With the rapid development of 3D visualization and modeling technology, it is possible to combine 3D technology with sunshine analysis to develop a 3D sunshine analysis system. Based on this point, this paper studies the building 3D visual sunshine analysis system, and completes the design and implementation of the 3D sunshine analysis system. The main work and results of this thesis are as follows: (1) after analyzing the related coordinate system and time system, the sunshine parameters and calculation model reflecting the sun's orbit are determined. (2) the Rod Shadow sunmap method and the two-dimensional CAD analysis method are summarized. After the advantages and disadvantages of conical surface method, a shadow analysis method based on undulating terrain is proposed in this paper, which solves the problem of shadow deformation under the condition of surface undulation. Finally, a correction algorithm is proposed. (3) based on the experiments of many 3D modeling methods, the method of introducing SketchUp into 2D CAD design drawing is determined, and this method is regarded as the main method of modeling the 3D sunshine analysis system in this paper. Three dimensional visualization experiments are also carried out on various elements of the Unity3D visualization platform. (4) based on the Unity3D 3D visualization platform, the paper designs the architectural visualization 3D sunshine analysis system, which realizes the first visual angle browsing and roaming, sunshine calculation. Shadow analysis and other functions. The sunshine data were collected in the field, and the calculation accuracy of the system was verified.
