Abstract

The invention relates to the technical field of building information, and provides a BIM loading method and device for a building information model and the method comprises the steps: obtaining a to-be-loaded BIM; determining primitives of a same material in the to-be-loaded BIM model; merging primitives of the same material in the to-be-loaded BIM model to obtain a target BIM model; according tothe distance from a scene center of the target BIM model to the viewpoint, generating at least one BIM model, wherein the precision of the at least one BIM model is different, wherein the scale of each BIM model in the at least one BIM model is not larger than a preset scale threshold value; when a front-end loading request carrying a scaling distance is received, determining a first BIM model inthe at least one BIM model according to the scaling distance; and loading the first BIM model to a front end for display. According to the technical scheme of the embodiment of the invention, the rendering efficiency of the BIM model can be improved.

Description

technical field [0001] The present application relates to the technical field of building information, in particular to a method and device for loading a building information model (BIM). Background technique [0002] Building information modeling (BIM) is one of the core concepts in the field of building informationization in recent years, and its data basis is the three-dimensional information model of the building. Compared with the traditional two-dimensional design and drawing, BIM technology makes full use of three-dimensional graphics technology, and uses the three-dimensional graphics of buildings (building components, buildings as a whole) as a carrier to further connect various building information parameters to form a BIM model, and then carry out construction The whole lifecycle management of objects and even components. [0003] For the display of 3D information models, the current technical solution is to display each component of the BIM model as a graphic el...
