基于等效模型替代的BIM构件实例化方法
The Method for BIM Model Instancing Based on Equivalent Model Substitution
摘要
Abstract
In the construction of digital twin cities,this paper aims to address the efficient processing and rendering of complex data in BIM.It proposes an instancing method based on equivalent model substitution.This method acquires line-based components through secondary development in Revit,and exports instances of components with the same profiles.Subsequently,in Unreal,the instantiated data is converted into HISM components,thereby achieving rapid importation of instantiated information of BIM into the rendering engine,significantly enhancing rendering efficiency without data loss.The results indicate that this method has optimized the instantiation effect of line-based models and improved graphic rendering performance.This method is applicable to various BIM formats and rendering engines,contributing to the development of digital twin cities.关键词
