Abstract: With the continuous advancement of informatization, digitalization, and intelligentization in the engineering field, the integrated application of 3D real scene models and as-designed BIM models has become increasingly prevalent. Distributed multi-terminal sharing for schedule management applications and the quantitative analysis of progress visualization within the real scene environment represent emerging trends. This paper develops software based on the open-source Cesium platform. Through the bounding box algorithm and ray casting method, similarity analysis between the real scene model and the BIM model is performed. This enables the automated calculation of engineering quantities and statistical analysis of construction output for custom-defined project areas and structures. Consequently, real-time quantitative analysis of project progress visualization is achieved, providing robust data support for project management. The practical application has demonstrated its effectiveness in engineering projects.
