Abstract

The present application discloses a tree structure model generation and loading method, device, storage medium and equipment, the method comprising: receiving an instruction to load the model of the target object; in response to the instruction, reading the specified level model of the target object from the model database And the edge vector of the specified level model, wherein the tree structure model is stored in the model database, in the tree structure model, the parent model is the merged model of multiple child models under it; load the specified level model, calculate the specified level model and The distance between cameras; according to the distance and the edge vector of the specified level model, calculate the weight of the specified level model within the camera field of view; according to the weight, read and load the parent model or child model of the specified level model from the model database level model to replace the specified level model. The present application solves the technical problem of low model loading efficiency in the prior art.

Description

technical field [0001] The present application relates to the field of computer-aided design, in particular, to a method, device, storage medium and equipment for generating and loading a tree structure model. Background technique [0002] With the improvement of the level of urbanization, more advanced management methods are needed to promote the construction of cities, so CIM has gradually become one of the first policy goals of many cities. CIM (City Information Modeling) is the city information model, based on the building information model (Building Information Modeling, BIM), geographic information system (GIS), Internet of Things (IoT) and other technologies as the basis, integrating the urban ground and underground, indoor and outdoor, historical status quo In the future, multi-dimensional and multi-scale information model data and urban perception data will construct an organic complex of urban information in a three-dimensional digital space, which is a giant syste...
