Real-time BIM model rendering method and device based on browser

Abstract

The invention discloses a real-time BIM model rendering method and device based on a browser. The method includes the following steps of sending a graph calculation request; receiving the request andestablishing a websocket between a client side and a server; processing the request and creating a calculation instance; using the calculation instance to generate a model; feeding back the model to the client side and saving the model; rendering the model; displaying the rendered model. According to the scheme, a BIM model is processed on the server side and rendered and displayed on the browser,the problems of slow rendering speed and high computer performance requirements of current online rendering software are solved, storage and calculation of all BIM models are completed on the cloud server, and the client side can conduct rendering only through the browser to meet the rendering needs of different users in different areas and different time; in addition, users can check geometric information, physical information and other required parameters of components in real time while seeing the realistic rendering effect.

Description

technical field [0001] The present invention relates to a BIM model rendering method, in particular to a browser-based BIM model real-time rendering method and device. Background technique [0002] BIM, the full name of Building Information Modeling (Building Information Modeling) or Building Information Management (Building Information Management) is based on the relevant information data of construction projects, establishes a three-dimensional building model, and simulates the structure of the building through digital information simulation. have real information. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. [0003] There are a large number of scenarios and requirements for model rendering in architectural design or industrial design, and these model renderings are currently based on desktop software (such as 3ds MAX, Rhinoceros, etc.), which ...

Problems solved by technology

[0005] The above-mentioned technical parties reduce the performance requirements for the rendering terminal by reducing the weight of the BIM model, excluding the visible model, and performing hierarchical rendering on the mobile terminal. Rendering, and needs to rely on client-side programs for rendering

[0006] Therefore, it is necessary to design a real-time rendering method for BIM models based on browsers, so that the calculation and rendering in the BIM modeling process can be placed on the cloud server for processing and storage, and the BIM model can be rendered in the terminal browser. In the case of a network, the retrieval of models and the online rendering of BIM can be realized, which solves the problems of desktop BIM modeling software's high performance requirements for computers, high procurement costs, and complicated installation
