Problems solved by technology

[0004] However, the above method of UV unwrapping the 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 effect of UV unwrapping is poor.

Abstract

The present application provides a method, device, device, storage medium and program product for unfolding a three-dimensional model, and relates to the technical field of virtual scenes. The method includes: cutting and unfolding 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 and combining sequence includes a combination of basic splicing units based on model expansion requirements. Each splicing combination; the model deployment requirements include at least one optimized energy based on model design requirements; verify each splicing combination in the splicing combination sequence, and obtain the splicing result of the basic splicing unit; based on the splicing result of the basic splicing unit, generate Unwrapped results of the 3D model. The above method realizes the automation of the unfolding process of the 3D model, and at the same time fully considers the actual demand in the model design, so that the unfolding result of the 3D model is more in line with the actual demand, and the unfolding effect of the 3D model is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of virtual scenes, and in particular, to a method, apparatus, device, storage medium, and program product for unfolding a three-dimensional model. Background technique [0002] UV unwrapping is an important link in the production of art resources, mainly including two unwrapping methods, 1UV and 2UV. [0003] In the related art, when UV unfolding a 3D model, it is necessary to find the shortest possible 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 method for UV unwrapping of a 3D model only constrains the UV unwrapping problem to two conditions, the length of the secant line and the degree of distortion, so that the basis for UV unwrapping is limit...
