Three-dimensional model expansion method and device, equipment, storage medium and program product

Abstract

The invention provides a three-dimensional model expansion method and device, equipment, a storage medium and a program product, and relates to the technical field of virtual scenes. The method comprises the following steps: cutting and expanding a three-dimensional model to obtain a basic splicing unit set of the three-dimensional model; constructing a splicing combination sequence based on the basic splicing unit set; the splicing combination sequence comprises each splicing combination obtained by combining each basic splicing unit based on a model expansion requirement; the model expansion requirement comprises at least one kind of optimization energy formulated based on the model design requirement; verifying each splicing combination in the splicing combination sequence to obtain a splicing result of the basic splicing unit; and generating an expansion result of the three-dimensional model based on the splicing result of the basic splicing unit. According to the method, automation of the three-dimensional model unfolding process is achieved, meanwhile, actual requirements in model design are fully considered, the unfolding result of the three-dimensional model better meets the actual requirements, and the unfolding effect of the three-dimensional model is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of virtual scene technology, and in particular to a method, device, equipment, storage medium and program product for unfolding a 3D model. Background technique [0002] UV unfolding is an important link in the production of art resources, mainly including 1UV and 2UV unfolding methods. [0003] In related technologies, when UV unwrapping a 3D model, it is necessary to find the shortest cutting line on the 3D grid to cut the model, and calculate the mapping relationship from the 3D coordinate point to the 2D coordinate point, so that the result There is as little distortion as possible and the result of the cut is tiled into UV space. [0004] However, the above-mentioned method for UV unwrapping of a 3D model only constrains the UV unwrapping problem to the two conditions of the secant length and the degree of distortion, so that the basis for UV unwrapping is relatively limited, and the ...
