Closed area searching method and device and electronic equipment

Abstract

The invention relates to the technical field of three-dimensional modeling, in particular to a closed area searching method and device and electronic equipment. The method comprises the steps of obtaining a graph structure corresponding to a target drawing and position information of a target point, wherein the drawing structure comprises a closed area in the target drawing; taking the target point as a starting point, searching a point closest to the target point and a corresponding edge in the graph structure along a first preset direction to obtain an initial search point and an initial search edge; and searching the graph structure based on the initial search edge, and determining a closed region surrounding the target point. A graph structure corresponding to the target drawing is obtained before the closed area is searched; due to the fact that the graph structure comprises the closed area in the target drawing and is established between the searches, the establishing time of thegraph structure is saved in the searching process, the search only needs to be conducted in the graph structure, the searching time consumption of the closed area is greatly reduced, and the searching efficiency of the closed area is improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a search method, device and electronic equipment for a closed area. Background technique [0002] To establish a 3D model in the field of architectural modeling, it is mainly to determine the overlooking range of the model according to the specified area after inputting parameters. The traditional way to determine the overlooking range is directly through rectangle, arc or edge-by-edge drawing. In addition, secondary operation commands such as copying and moving can also achieve the goal. [0003] In order to improve the efficiency of 3D modeling more efficiently, users often need to determine the overlooking range of the model based on CAD drawings, such as the range of overlooking areas such as cast-in-place slabs, straight steps, and road surfaces. With the development of BIM, how to effectively use CAD drawings to quickly guide users to complete the establ...
