Abstract

The invention relates to a BIM (Building Information Modeling) extended storage method, which comprises the following steps of: processing a BIM scene, extracting data and storing the data in an independent file manner, the independent files comprise a scene file, a scene overall attribute file, an asset file list file, a camera instance list file, a camera definition list file, a light instance list file, a light definition list file, a fragment instance list file, a geometric metadata list file, a geometric definition list file, a material list file and a texture mapping list file; the system comprises an object ID list file, an attribute category list file, a value list file, an attribute category-value pair list file and an attribute category-value pair offset list file. The independent files are quoted in a one-way mode, and the overall description of the complete BIM is formed. The storage method provided by the invention has the characteristics of small file volume, high storage speed, good transmission performance, high drawing efficiency, strong expansibility and the like, and meets the use requirements of a lightweight system of the BIM model.

Description

technical field [0001] The invention relates to the field of BIM model storage, in particular to an extended storage method for BIM models. Background technique [0002] BIM, the full name of Building Information Modeling, also known as Building Information Modeling, refers to the digital expression of the physical and functional characteristics of buildings and their facilities in computers, providing shared information resources during the entire life cycle of construction projects, and providing support for various decision-making. A technology that provides basic information and is widely used in the construction industry. [0003] Large-scale building BIM models contain tens of thousands of structures, and the model files are huge in size, mainly including two aspects of information: geometric model information and BIM attribute information. The volume of geometric model information is huge, and when it is used directly, it requires high computer performance and networ...
