Description

technical field

[0001] The invention belongs to the technical field of BIM data processing, and in particular relates to a BIM data processing method, equipment and system. Background technique

[0002] With the advancement of human science and technology, the GIS platform has become a direction of development from two-dimensional to three-dimensional. The three-dimensional GIS platform can load multi-source heterogeneous data, including massive data such as elevation, image, precise model, and BIM model. The large volume and complex structure of BIM model data, and the large volume of model data in a small area, etc., cause the GIS platform to load BIM model data slowly and the view freezes, making it possible for 3D GIS scenes to provide efficient data loading. inevitable.

[0003] In order to improve the loading and rendering performance of 3D scenes, the data is processed in a fragmented manner in the BIM data production process, which can effectively relieve the memory...
