Embodiment 1

[0037] refer to figure 1 , the present invention a kind of method for large-scale industrial three-dimensional model rendering, comprises the following steps:

[0038] 1. Modeling engineers use blender modeling software to draw a 1:1 production line model according to the actual production line layout on the industrial site, export files in GLB / GLTF format, and provide them to front-end developers.

[0039] 2. The modeling engineer and the front-end developer review the first draft of the designed model, and discuss the component structure, naming convention, etc. If modification is required, the modeling engineer will adjust, modify and re-export until it meets the development specification (the development here Specifications refer to software development specifications. The data structures that need to be parsed in large-scale models are generally relatively large, so more conventions and constraints are required to standardize the data structures of the models).

Abstract

The invention provides a method for rendering a large-scale industrial three-dimensional model, which comprises the following steps: S1, a modeling engineer exports a model file according to an actual industrial field layout; s2, a modeling engineer and a front-end developer evaluate the model file, and if the model file conforms to the development specification, the step S3 is carried out; otherwise, the process is returned to the step S1; s3, the front-end developer renders the model, specifically, S31, the model is loaded; s32, the grid model is compressed through a model compression tool; s33, if the model is loaded for the first time, the file is cached into the indexDB; if the model is not loaded for the first time, the corresponding model is directly queried in the indexDB to obtain binary data; s34, whether the model contains an animation or not is judged; and if the analyzed model data contains animation data, the animation is rendered by using an ANIMATIONMIXER tool; and otherwise, the GLTFLOADER is directly used for rendering. According to the method, the browser can be used for loading and rendering the three-dimensional model anytime and anywhere, and the software development and application cost of enterprises is greatly reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of model rendering, in particular to a large-scale industrial three-dimensional model rendering method. 【Background technique】 [0002] 1. OpenGL (Open Graphics Library: Open Graphics Library or Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. This interface consists of nearly 350 different function calls used to draw everything from simple graphics bits to complex 3D scenes. Yet another program interface system is Direct3D on Microsoft Windows only. OpenGL is commonly used in CAD, virtual reality, scientific visualization programs, and video game development. [0003] 2. WebGL provides the ability to directly deal with the underlying OpenGL library through the browser. [0004] 3. three.js is a tool library that is further encapsulated and simplified on the basis of WebGL, and it can also be called a "3D engine"....
