针对模块化建筑BIM模型显示的轻量化图形引擎应用研究OA

Modular construction significantly enhances project quality,cost-efficiency,and sustainability in the building industry.Although Building Information Modeling(BIM)technology improves data integration and model visualization during the design process,its current applications heavily rely on commercial BIM software with graphical user interface(GUI)-based modeling.This approach often suffers from limitations such as platform dependency,challenges in collaborative development and data interoperability,and cumbersome operations for information exchange.To address these issues,a lightweight graphics engine based on the OpenGL framework was developed and applied to modular BIM models.The proposed engine facilitates IFC-to-OBJ and IFC-to-STL file format conversion,rapid assembly and stacking of building modules,and common interactive operations including translation,rotation and scaling.It also allows three-dimensional rendering and data interaction of BIM models.The results demonstrate that the proposed engine achieves visual quality comparable to that of the commercial software Blender,while providing more efficient and stable interactivity.The system considerably improves design efficiency and scene adaptability,offering practical value for enhancing digital design and collaborative model management in construction engineering.
