Building model processing method and device, computer equipment and storage medium

Abstract

The embodiment of the invention provides a building model processing method and device, computer equipment and a storage medium, and the method comprises the steps: displaying a selection list on a current webpage interface when a model display instruction is received, and determining a to-be-displayed building model after lightweight processing; obtaining geometric data corresponding to each component of the to-be-displayed building model, generating an index array according to the geometry of each component of the to-be-displayed building model and the corresponding vertex data set, and obtaining an index array set; screening geometries with the same building data from the index array set to obtain a merged index array; displaying the to-be-displayed building model on the webpage interface; according to the embodiment, the drawing frequency is greatly reduced, and the rendering efficiency is improved; operations such as color change or isolation can be quickly and simply performed onthe whole component of the BIM model at the Web end according to the modification instruction, so that the modification difficulty of the BIM model after the BIM model is displayed at the Web end isreduced.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method and device for processing architectural models, computer equipment and storage media. Background technique [0002] With the continuous advancement of construction industrialization and housing industrialization policies, prefabricated building technology and building information modeling technology (Building Information Modeling, BIM) are continuously applied to all aspects of construction engineering. Among them, BIM technology has the advantages of visualization, information parameterization, and collaboration, which greatly improves the efficiency and quality of engineering design. When designing in buildings, BIM software is often used to pre-generate models, and BIM software is used to quickly generate a three-dimensional model to simulate the expected effect of the target building, which is convenient for designing multiple sets o...

Problems solved by technology

In the prior art, since the BIM model usually includes multiple components, when displaying the BIM model on the Web side, each component needs to be rendered separately on the Web side, and multiple draw calls (draw calls) need to be made. Occupies the central processing unit (CPU, central processing unit). Therefore, if the drawing is called too many times, the CPU will take longer and the drawing frame rate will be slower, and the time required to draw the BIM model on the Web side will be longer, resulting in The display efficiency of the BIM model on the web side is low; moreover, in the prior art, after the BIM model is displayed on the web side, it will be logically difficult to change the color or isolate the component as a whole, which increases the difficulty of development
