The platform provides functions of efficient indexing, topological analysis, total-element lightweight loading and efficient rendering of model data, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of CIM application platform, in particular to a CIM-based all-element mass data lightweight and topology analysis application platform. Background technique [0002] The concept of City Information Modeling (CIM, City Information Modeling) extends the concept of BIM (Building Information Modeling) to the digital modeling of complete building information for design, construction, use, and maintenance life cycle management to the urban field. In terms of spatial scope and technical logic, the construction of CIM is an organic combination of "GIS (Geographic Information System) data of large scenes + BIM data of small scenes + Internet of Things (Internet of Things)". [0003] Therefore, after CIM technology is applied to smart cities, it will inevitably face large-scale, dynamic and real-time massive model data information.

AI Technical Summary

Problems solved by technology

[0003] Therefore, after CIM technology is applied to smart cities, it will inevitably face large-scale, dynamic and real-time massive model data information. In the face of massive model data, the browsing performance of the scene is also affected. The traditional method cannot be efficiently, quickly and smoothly manipulated and browsed. The conventional model data has not been vectorized and extracted from the elements and objects, and cannot meet the requirements of the object materialization standard. On the visualization platform In addition, the general model data cannot be used for spatial topology analysis applications, such as engineering construction pipeline collision analysis, connectivity analysis, etc.

Therefore, there are many problems and challenges in the common application method, such as dynamic loading of massive data, browsing performance, lossless full elements, object materialization, spatial topology analysis, etc.
