基于Revit和Unity3D的三维车间可视化研究

Research on 3D Workshop Visualization Based on Revit and Unity3D

大型规模车间建设过程中为保障按时投产达产,对车间公辅配套建设和工艺设备安装调试周期提出了更高的要求。为解决项目建设中存在的管理协调、施工碰撞以及后期运维等问题,传统的CAD图纸二维平面图纸设计已经不能满足实际的需求。依托Revit和Unity3D平台进行车间BIM模型的设计和可视化研究,从BIM建模、BIM模型导入、BIM数据导入等关键技术的研究,解决BIM模型兼容性问题和BIM数据导入丢失的问题。从渲染场景优化、模型的动态合并批处理、实时光照和阴影效果优化等关键技术的研究,提高了整个三维车间的渲染效率,实现了三维车间的可视化和漫游。

During the construction of large-scale workshops,in order to ensure the on-time production,higher requirements are put forward for the construction of public auxiliary facilities in the workshop and the installation and commissioning cycle of process equipment.In order to solve the problems of management coordination,construction collision,and later operation and maintenance in project construction,the traditional two-dimensional plane drawing design of CAD drawings can no longer meet the actual needs.Relies on the Revit and Unity3D platforms to realize the design and visualization of the workshop BIM model,from the research on key technologies such as BIM modeling,BIM model import,and BIM data import,to solve the problem of BIM model compatibility and loss of BIM data import.From the research of key technologies such as rendering scene optimization,dynamic merging and batch processing of models,real-time lighting and shadow effect optimization,the rendering efficiency of the entire 3D workshop is improved,and the visualization and roaming of the 3D workshop are realized.
