Research On City 3D Modeling Based On 3Dsmax And Skyline

With the rapid development of urban construction in China,although the information reflected by two-dimensional GIS is accurate enough,it lacks intuition and is difficult for ordinary users to understand at a glance.Therefore,under the current trend of expanding urban construction scale,3D GIS,which reflects the difference between accurate information and details,needs to be developed.With the help of 3D modeling technology,users can easily simulate a 3D virtual environment similar to the urban real environment.This virtual environment not only provides users with an immersive sense of reality,effectively enhancing users' understanding of urban layout and understanding of data information,but also helps to integrate the data information of various industrial fields in the city,to realize the rational distribution of public resources,and to promote multi-dimensional and deep-level comprehensive development and progress of urban construction and management.Nowadays,the construction of “Smart China” and “Digital China” is mainly for a large area of the city,but lacks research and planning for details of some small areas of the city and residential areas.It is important to construct the layout of the city and the overall construction model.However,the study of the landscape model of the residential community cannot be ignored,which is of great significance for improving people's life convenience.Therefore,this paper takes a city community as an example for 3D modeling.The main research contents and findings are as follows:(1)The basic characteristics of 3D spatial objects are described.The classification of 3D spatial data models is carried out according to certain rules.The data sources and acquisition methods of 3D urban modeling are discussed.(2)According to the 3D visualization theory,the 3D visualization process in urban 3D modeling is deeply studied.The classification of coordinate system,the use of rendering tools and the application of key technologies of 3D visualization to the importance of constructing 3D models are pointed out.(3)The demand analysis of the 3D modeling of urban communities is carried out,and the basic elements of 3D modeling of urban communities are obtained.The modeling methods and technical routes of 3dsMax in 3D modeling are pointed out.In addition,using 3dsMax modeling software to complete the modeling of a certain residential area and surrounding buildings,through the modeling of various elements,the characteristics of the features in the community are displayed,compared to the projects in the modeling of large-area areas in the ordinary residential community,the cell model of this experiment is more detailed in the details of the model.(4)The 3D model scene is roamed through the Skyline software.(5)The 3D model is used in the planning work.
