Rendering method and device based on BIM model and WebGL

Abstract

The invention discloses a rendering method based on a BIM model and a WebGL applied to a server side and a browser side. The server side is connected with the browser side, the server side converts aBIM model file into model data in advance, the number of the browser side is at least one, and the method comprises the steps that when detecting that any browser side logs in the server side, sendingthe model data to the current browser side; enabling the current browser end to convert the model data into a target BIM model; and carrying out rendering display on the target BIM model through WebGL. According to the method, the BIM model file and the process of converting the BIM model file into the model data are completed at the server side, software does not need to be installed at the browser side, and the memory of the browser side is not occupied, so that the problem of blockage or discontinuity in the display and rendering process is solved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, and in particular, to a rendering method and device based on a BIM model and WebGL. Background technique [0002] Due to the drawbacks of the 2D mode of CAD technology, engineering conflicts are common in the traditional CAD era. These conflicts are often only perceived afterward, which greatly reduces the efficiency of design and construction and seriously increases costs. With the application of Building Information Modeling BIM (Building Information Modeling) technology, the display and rendering of 3D views can be achieved by establishing 3D visualization models and cooperating with relevant BIM software. [0003] However, the existing BIM model requires software to be installed on the computer, which is troublesome to install and occupies a large amount of memory, resulting in the 3D view stuck or discontinuous in the display and rendering process.
