With the application of the BIM building information model technology in the field of engineering construction, the organization and expression mode of the traditional engineering project information are gradually changed, in the era without BIM, the engineering project information is mostly organized in a discrete mode and is displayed to users in a two-dimensional chart mode, in the BIM-based engineering project management application, various project information is associated with a three-dimensional BIM model through unified coding, and the users are more intuitively displayed to the users through the three-dimensional BIM model.
The existing simulation platform realizes translation, scaling and rotation operations of a three-dimensional model by applying an OpenGL interface and changing a two-dimensional position of a mouse, but in engineering project management application based on BIM, a user needs to perform various complex interactive operations with the BIM model, such as model/component selection, model sectioning, marking, measuring, roaming and the like with different granularities.
Meanwhile, the existing WebGL technology realizes the display of a heterogeneous CAD model by a cross-platform Web browser, but when the three-dimensional graph rendering is carried out by adopting the method, a large amount of terminal equipment resources are consumed, the hardware resources consumed by the rendering model can be rapidly increased along with the increase of the number of the three-dimensional model, and when the volume of the model exceeds the bearing range of user terminal equipment, the phenomenon of program jamming or collapse can occur.
In summary, the conventional three-dimensional graphics rendering technology can realize the graphics display function, but is not enough to fully support the display requirement of the BIM-based engineering project management application on the three-dimensional BIM model. In order to solve the problems, the application document provides a high-efficiency virtual simulation experiment platform based on cloud rendering, and the high-efficiency virtual simulation experiment platform can be used for quickly rendering, testing and displaying a model.
