Research On Reverse Time Reproduction Of Ancient Architecture Relief Based On Parametric Design

With the continuous progress of science and technology,the protection mode of cultural heritage has also changed,from traditional physical restoration to technology-assisted restoration,three-dimensional virtual reconstruction and digital information dissemination.More and more international organizations and governments are beginning to realize the importance of digital protection and actively promote related technologies.Although digital technology plays an increasingly important role in the protection of cultural heritage,there are still many problems in the existing technology,such as insufficient interaction with the public,lack of literature support for the results of three-dimensional reconstruction,and only research on individual diseases.In order to solve the problems of digital protection technology of cultural heritage,new ideas need to be put forward.As an important cultural heritage in China,ancient architectural relief has high artistic value and research value,but it is often regarded as a secondary element of architecture,lacking relevant repair norms and technical support.In ancient buildings,reliefs are concentrated on the shadow wall in front of the buildings,so this paper takes the shadow wall as the research object,explores new digital protection methods,and provides new ideas for the digital research of cultural heritage.Parameterization is a digital concept,which has been gradually applied to the design field and formed a new design method.This method is to establish the system by using parameters,so as to meet the design requirements.It has a wide range of design objects,uncertain design process and real-time feedback design results,so it can be applied to many fields.Revisiting in reverse time refers to simulating the changing process of cultural heritage from now to the past,emphasizing the importance of cultural heritage changing with time and clarifying the key points of digital protection.In this study,the parameterization technology and the concept of reverse-time revisiting are combined,and the time parameter is increased,and the parameterized system of reverse-time revisiting of ancient architectural reliefs is innovatively proposed.Based on all the diseases of the screen wall,the system sorts out the logical relationship between diseases and time,and builds a disease simulation database by using Blender platform,that is,the parameterized system of reverse-time revisit of ancient architectural reliefs.The specific research work is as follows:(1)The method of digital protection of ancient architectural reliefs is determined: the shadow wall is selected as the research object,the changes of shadow wall with time development are sorted out,and its diseases are classified.Based on the concept of reverse-time revisiting,a reverse-time revisiting parameterized system is proposed by using parameterized technology.(2)The parameter structure of screen wall disease is established:according to the phenomenon of screen wall disease,the visual representation characteristics of screen wall disease are summarized,the influencing factors of disease representation are analyzed,the corresponding parameters are summarized,and the parameter logic framework of disease is constructed.(3)Completed the construction of the parameterized reverse-time revisiting system: according to the underlying logic of the Blender platform and the parameters of the disease,the corresponding node group was designed,so as to realize the construction of the parameterized reverse-time revisiting system of the shadow wall.(4)Showed the practical application results of the retrospection parameterization system: Taking Three-Dragon Screen as a case,we first digitized Three-Dragon Screen,and successfully realized the retrospection process of Three-Dragon Screen from now to the past by using the retrospection parameterization system.The success of this case verifies the effectiveness of this method.
