【摘要】：隨著經(jīng)濟的快速發(fā)展,居民對居住條件有了更高的標準與要求,太陽光照作為考查住宅舒適度的主要因素之一逐漸被人們關注,因為采光權引起的糾紛也日漸增多。此外,日照分析報告也是建筑竣工驗收的必要提交材料之一。于是對具有日照分析功能的軟件的需求迅速增長。由于分析方法本身的適用性與局限性,傳統(tǒng)的手工日照分析方法與基于CAD的二維日照分析方法已逐漸不適用于目前各式各樣建筑物的日照分析。在三維可視化與建模技術快速發(fā)展的背景下,將三維技術與日照分析結(jié)合起來開發(fā)出三維日照分析系統(tǒng)已經(jīng)成為可能。本文基于此點,對建筑三維可視化日照分析系統(tǒng)進行研究,并完成了三維日照分析系統(tǒng)的設計與實現(xiàn)。本論文的主要工作與成果如下:(1)在分析了相關坐標系與時間系統(tǒng)后,確定了反映太陽運行軌跡的日照參數(shù)及計算模型。(2)在總結(jié)了棒影日照圖法、二維CAD分析法、圓錐曲面法的優(yōu)缺點后,本文提出了基于起伏地形的陰影分析方法,解決了在地表起伏條件下陰影發(fā)生形變的狀況,并提出了改正算法。(3)通過對多種三維建模方法進行實驗,確定了以二維CAD設計圖為底圖導入SketchUp進行建模的方法,并將此方法作為本文三維日照分析系統(tǒng)建模的主要手段。對Unity3D可視化平臺的各個要素也進行了三維可視化實驗。(4)基于Unity3D三維可視化平臺,論文設計了建筑可視化三維日照分析系統(tǒng),實現(xiàn)了第一視角瀏覽與漫游、日照計算、陰影分析等功能。實地采集了日照數(shù)據(jù),并對系統(tǒng)計算精度加以驗證。
[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.
