3D Digitization And Application Of Historic Building

The city historical and cultural block is the material heritage of the city in the special historical period and the important historical and cultural heritage of all mankind.However,along with scientific progress and economic development,it is the single and one-sided means of protecting and displaying urban historical and cultural blocks.3d digital technology can play an important role in the research,protection,introduction of human history and historical heritage.Meanwhile,by virtue of its information-based technical features,it can combine the concept of "Internet +",and promote the historical and cultural blocks to various aspects of modern society,which has been widely recognized in the international field.Firstly,this paper introduces 3d digitization technology,elaborates the research background and purpose of this paper,describes the development and application of 3d digital technology and virtual reality technology in the protection of urban historical and cultural blocks at home and abroad,and summarizes the problems of current technology in the protection of urban historical and cultural blocks.Secondly analyze the history and the morphological characteristics,inmin street mainly from the history,physical space characteristics,the nonphysical space characteristics and specific style building four aspects,this chapter is about understanding of xinmin street,for the urban historical and cultural blocks of 3Ddigital structure form and the basis of ideological concept.Then this paper mainly expounds the current mainstream digital building blocks of the method,principle and technology tools,at the same time,according to the research,focuses on the typical architectural components of color and model library building and historic buildings restoration technology,then introduced in Unity3D digital blocks roaming the two 3D digital modeling technical requirements.Then,in block 3D digital,where the color restoration,building a typical decoration model library of components and virtual roaming system four aspects for the research and implementation of 3D digital xinmin street,work with scientific strategy and methods to guide the research,found the problem on the application example,using the method of model import will block 3D digital model applied in blocks the development of three-dimensional roaming system,summarizes the application experience.Finally,urban historical and cultural blocks of 3D digital work is summarized and prospected,overview of major work,summing up experience and lessons,and at the same time use of divergent thinking development,3D digital model of the application way to other areas in the city,in order to meet the needs of citizens in the city development and construction of spiritual civilization,looking forward to the prospect of historical and cultural blocks of 3D digital city.
