Problems solved by technology

[0004] However, even though the original grid is deleted, the rendering of the merged BIM still results in a transient increase in memory usage, especially for larger BIMs. The transient increase in memory is likely to cause memory overflow, causing the program to crash

Abstract

The invention relates to the field of computer graphics, and provides a BIM rendering method and equipment based on a lightweight device, and a computer readable storage medium, so as to prevent program flash back while accelerating BIM rendering. The method comprises the following steps: analyzing the complexity, dynamic and static characteristics and / or geometrical characteristics of a buildingthree-dimensional model according to geometrical structure data of the building three-dimensional model; generating a corresponding hierarchical bounding box tree structure, a binary segmentation space tree structure or an octree structure according to an analysis result obtained by analyzing the complexity, the dynamic and static characteristics and / or the geometrical characteristics of the three-dimensional model of the building so as to record information of the three-dimensional model of the building; and based on an algorithm of a hierarchical bounding box tree structure, a binary segmentation space tree structure or an octree structure, reading information of the building three-dimensional model from a memory, and rendering an effective part of the building three-dimensional model. According to the technical scheme, when the building three-dimensional model is rendered, memory occupation can be reduced, and therefore the rendering process can be accelerated.

Description

technical field [0001] The present invention relates to the field of computer graphics, in particular to a BIM rendering method, device and computer-readable storage medium based on lightweight equipment. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is based on the relevant information data of the construction project as the basis of the model, to establish the building model, and simulate the real information of the building through digital information simulation. For visualization or other purposes, BIM is generally rendered on display devices of electronic devices such as computers (for example, personal computers, etc.). [0003] With the development of smart mobile terminal technology, the central processing unit of smart mobile terminals is becoming more and more powerful. Many BIMs that must be rendered on powerful electronic devices such as personal computers can also be rendered on lightweight devices such as smart...
