Problems solved by technology

[0004] However, the inventor found in the course of the research that the BIM building simplified model generated by the ReMesh method in the prior art has a large number of triangles. For example, for an ordinary residential building, there are generally more than 10,000 triangles to express. As a result, the overall performance of the CIM model is poor; the BIM architectural model generated by stretching the Shape contour can only describe a simple and regular architectural model, and cannot well restore architectural models with different upper and lower contours, and the universality is poor

Abstract

The invention discloses a method for generating a building simple model. The method comprises the following steps: acquiring a target building model of a to-be-generated building simple model; the target building model is transversely cut into N sub-building models, a contour line set of a target transverse plane in each sub-building model is sequentially obtained according to the cutting sequence, N + 1 contour line sets are obtained, and each target transverse plane is the transverse plane of which the contour line set is not obtained in the corresponding sub-building model; determining a target outer contour line set according to each contour line set; and generating a building simple model of the target building model according to the N + 1 target outer contour line sets. The invention further discloses a device for generating the building simple model, computer equipment and a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of computer-aided design, in particular to a method, device, computer equipment and computer-readable storage medium for generating a simplified architectural model. Background technique [0002] In the CIM (City Information Modeling, city information model) model, the architectural model is a very important component. CIM models are generally large in size and contain many architectural models. Therefore, when displaying a city-level model, a simplified architectural model is generally used to represent a complete architectural model. [0003] In the prior art, there are some methods for manually generating architectural simplified models, such as: using 3DS Max software to establish architectural simplified models, using SketchUp software to establish architectural simplified models, using Shape format files to describe the outer contour of architectural models and generating them through stretching algori...
