[0006] The purpose of the present invention is to provide an intelligent editing method for a three-dimensional model that maintains the structure, by using spheres, cylinders, and cuboids as controllers to carry out cluster analysis on the three-dimensional model to obtain controllers that are close to the components themselves and establish a relationship between different controllers. Corresponding relationship; at the same time, position adjustment, shape scaling, and evidence transformation are respectively performed on the controllers obtained by cluster analysis; semantic structure information editing is realized; the existing 3D model editing lacks semantic structure information, lacks sharp features, and editing effects bad question

The invention discloses a three-dimensional model intelligent editing method capable of maintaining a structure, and relates to the technical field of three-dimensional model intelligent editing. Themethod comprises model analysis and model editing. According to the method, a three-dimensional model is clustered and analyzed by using a sphere, a cylinder and a cuboid as controllers to obtain a controller approaching a part, and a corresponding relationship is established among different controllers; Meanwhile, position adjustment, shape scaling and proof transformation are carried out on thecontroller obtained through clustering analysis; semantic structure information editing is achieved, necessary semantic structure information and necessary sharp graph features are added, and the editing effect is improved.
Description
technical field [0001] The invention belongs to the technical field of three-dimensional model intelligent editing, in particular to an intelligent editing method for a three-dimensional model maintaining structure. Background technique [0002] The 3D model editing is based on the existing model and can generate a new model, which is very useful for model reuse. In recent years, mesh editing techniques, especially for artificially synthesized models, have focused more on maintaining structural, high-level features than maintaining local, low-level geometric features. However, most of the public models are basically represented only in the form of polygonal surfaces, lacking semantic structure information. Therefore, before editing the model, it is usually necessary to analyze the model first, that is, the method of analyzing first and then editing. In general, some geometric constraints can be obtained from model analysis. When editing the mesh, the geometric constraints...
