Research on Modeling of Arch Bridge Based on Open CASCADE
The geometry engine is a core component of 3D BIM modeling software,which has a great impact on the performance,accuracy,interoperability and user experience of software.Although the geometry engine of commercial software has good performance and stability after years of development and optimization,it is often limited by the API interface provided by software manufacturers and the system environment required by commercial software.It cannot access or modify the underlying data,which has poor flexibility,and it does not have completely independent commercial copyrights.There have been relevant findings in many fields based on the application of open-source geometry engine,but there are few in the field of bridge engineering.The modeling technology in the field of bridge engineering is explored based on the open-source geometry engine Open CASCADE to realize an autonomous and controllable 3D modeling platform for bridge engineering,which takes the arch bridge as the research object and combines the modeling technology of geometry engine to realize the creation of an arch bridge model.It is committed to exploring the modeling realization capability of open-source geometry engine in the field of bridge engineering,accumulating experience for realizing 3D modeling of more bridge types and further derivative applications based on models,and providing reference for building autonomous and controllable bridge engineering modeling software.
