The invention discloses a method for realizing large-scale Web3D model loading and presentation of a
data center. The method comprises the following steps: (1) standardizing the manufacturing processof a model, including material acquisition specification, model manufacturing specification, map manufacturing specification, scene collapse specification and the like; (2) formulating a
standard model loading process which comprises the steps of acquiring model equipment information, analyzing the model equipment information, and compiling a standard WebGL loading function to load the model; (3)designing a classification scene loading
algorithm which comprises the following steps: dividing a large-scale
data center scene into different areas, compressing, transmitting and loading a model file after scene division to the local, decompressing the model file, and storing the decompressed model file; using a WebGL loading function to load a model, firstly loading a main scene model, and loading the model in a corresponding sub-region only when being clicked. By utilizing the method, large-scale equipment models can be loaded in
data center display, and the difficulty and the time lengthof loading large-batch models at one time are reduced.
