Method, device and equipment for correcting UV coordinates and computer readable storage medium

Abstract

The invention relates to the field of computer graphics, provides a method, a device and equipment for correcting UV coordinates and a computer readable storage medium, and aims to reduce consumption of computing resources and enable a texture mapping result to be a normal effect. The method comprises the following steps: performing UV tiling on the surface of a virtual model to obtain a plurality of continuous rectangles; performing basic operation on the UV coordinates of the three vertexes of the rectangle and the side length ratio of the quadrilateral patch corresponding to the rectangle to obtain the UV coordinates (UM, VM) of the point M; based on a first interpolation algorithm, calculating UV coordinates (UMOri, VMOri) of the point M and UV coordinates (UM00, VM00) of a point M0 on the same straight line with the point M in the triangle; and correcting UM00 or VM00 of the UV coordinate of the point M0 by taking the UV coordinate of the right-angle vertex of the triangle, the UV coordinate (UMOri, VMOri) of the point M and the UV coordinate (UM00, VM00) of the point M0 as operation objects. According to the technical scheme, consumption of computing resources is small, and acceleration of rendering is facilitated.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method, device, equipment and computer-readable storage medium for correcting UV coordinates. Background technique [0002] In the field of computer graphics, UV coordinates are the abbreviations of U and V texture map coordinates, and can also be called texture mapping coordinates, which can define the position of each point in a two-dimensional image. In the virtual model, UV coordinates can accurately correspond each point on the image to the surface of the virtual model, so that the virtual model can present corresponding visual effects. [0003] When rendering a virtual model, UV tiling is an essential link. The so-called UV tiling refers to converting the surface of a virtual model into a flat representation. Generally, since the UV coordinates are obtained by linear interpolation of the UV coordinates of the vertices of each patch (for example, a triangle patch, a quad...
