Industrial scene 3D model rendering method and device

The invention provides an industrial scene 3D model rendering method and device, and the method comprises the following steps: employing multithreading to package a plurality of WebGL rendering modules, each WebGL rendering module being used for rendering the data of a corresponding to-be-rendered 3D model, so as to obtain a 3D model; acquiring a plurality of pieces of algorithm data, and importing the plurality of pieces of algorithm data into the plurality of WebGL rendering modules in a one-to-one correspondence manner; packaging the plurality of WebGL rendering modules after importing theplurality of algorithm data into a js class method, and packaging and compressing the js class method into a js file for rendering; and during application, instantiating a class method in the js filefor rendering, and calling at least one WebGL rendering module in the js file for rendering to realize rendering of corresponding 3D model data to be rendered. According to the invention, visual simulation of the whole product
