Embodiment Construction

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0030] The embodiment of the present application provides a model management method, which is used to perform selected management operations on the model components displayed in the display interface of the device; the model management method includes rendering the first candidate component in the display object, and by judging Determine whether there is a rendering mark in the frame selection range to determine the first selected component. This method of determining the selecte...

Abstract

The invention provides a model management method and device and electronic equipment, and the method comprises the steps: rendering of a first candidate component in a display object, and determininga first selected component through judging whether a rendering identification exists in a frame selection range or not; determining a second selected component by judging whether partial primitive vertexes corresponding to candidate primitives of the second candidate component are within the frame selection range or not; and determining a third selected component by judging whether all primitive vertexes corresponding to the candidate primitives of the third candidate component are within the box selection range or not. Rendering identifier judgment and primitive vertex judgment are combined to determine the selected component, so that the complexity of primitive vertex judgment is simplified, and the time for executing component selection is shortened.

Description

technical field [0001] The present application relates to the technical field of model management, and in particular designs a model management method, device and electronic equipment. Background technique [0002] In BIM (Building Information Modeling, Building Information Modeling), the number of components that make up the model is usually tens of thousands, and the number of vertices and faces that make up the components is more than tens of millions. In the existing technology, the operation of selecting some components in the display interface of the BIM model is realized through the method of vertices judgment, that is, to judge whether the vertices of each component are within the frame selection range in turn, and when the component vertices are within the frame selection range , the widget is selected. However, there are many defects in this method of selecting components. First, due to the huge number of vertices of the components, the operation of vertex judgmen...
