Research On Dynamic Simulation Of Urban Building Environment Based On Real-time Analysis

Builing and its existing urban environment contain various factors and related data,which together constitute a complex and dynamic system.Designers need to use modeling tools to model the urban architectural environment,understand the feasibility of design schemes,and make design decisions scientifically.However,the current urban three-dimensional model generally lacks a dynamic relationship construction and constraint evaluation mechanism,which restricts the feedback linkage between the relevant influencing factors in the design process and the urban building model.Unlike traditional modeling and analysis tools,a simulation game engine that uses dynamic constraint rules and real-time feedback for modeling operations provides a new way of thinking about problems and the perspective of observing the city,which makes this based on real-time analysis The feedback simulation game engine can be converted to a simplified simulation test platform to a certain extent.This paper selects the key section of "Tiebei New City" in Nanjing as an example to carry out dynamic simulation experiments of the urban environment.First use the city simulation game software "Cities: Skylines",which prioritizes the concepts of transportation and zoning,to establish a city building environment model with dynamic simulation rules.Combined with realtime visual analysis of specific indicators,optimization experiments are conducted through real-time interactive operations with dynamic models,and on this basis,dynamic simulation processes and methods based on real-time analysis are studied.Specifically,the article is divided into five chapters: Chapter 1 of the introduction clarifies the origin,content,purpose and method of research.Chapter 2 summarizes the current development of environmental simulation technology,especially the characteristics,implementation algorithms and application platforms of dynamic simulation technology,and then introduces the dynamic simulation platform with real-time analysis function-city simulation game engine.Chapter 3 introduces the tools of this research,Cities:Skylines simulation game platform,from the selection of the platform to the analysis of the platform composition,trying to analyze the platform data structure,dynamic rules,model database and operation mode and on this basis Design this experimental process based on existing research experience.Chapter 4 uses the Cities: Skylines platform to simulate the urban building environment,and then performs real-time analysis based on the simulation results.Through interaction with the dynamic simulation model,the upper-level planning program is used to perform optimization and comparison experiments.Chapter 5 summarizes the experimental process and the problems encountered in the research process,and proposes improvements.According to the summary of experimental and comparison between Cities: Skylines and other professional simulation platform,the characteristics of the dynamic simulation process of the urban building environment based on real-time analysis are summarized and the application prospect in design practice is predicted.
