Texture mapping method and device of three-dimensional model, storage medium and computer equipment

Abstract

The embodiment of the invention discloses a texture mapping method and device of a three-dimensional model, a storage medium and computer equipment. The method comprises the steps of obtaining first texture coordinate information which is texture coordinate information of vertexes of patches in the three-dimensional model; sampling a first preset texture through the first texture coordinate information to obtain a tiled image of the first texture image; sampling a second preset texture through the first texture coordinate information to obtain a second texture image; taking the color information of the second texture image as second texture coordinate information, and resampling the tiled image of the first texture image to obtain resampled texture data; and performing texture mapping on the three-dimensional model according to the resampled texture data. According to the technical scheme of the invention, even if the vertexes of the three-dimensional model patch are few, the precision of texture mapping is still not affected, so that the problem that the precision of texture mapping is reduced when the vertexes of the three-dimensional model patch are insufficient is well solved.

Description

technical field

[0001] The present application relates to the field of computer technology, in particular to the field of electronic games, and in particular to a texture mapping method, device, storage medium and computer equipment for a three-dimensional model. Background technique

[0002] In the field of computer graphics, texture mapping, also known as texture mapping, specifically refers to obtaining a set of texture-related values ​​called parameter space values ​​by applying a projection function to points in space. Texture mapping can be described by a general texture pipeline. The initial point of the texture mapping process is a position in space. This position can be based on world space, but more commonly it is based on model space.

[0003] The texture mapping method of the existing 3D model usually needs to obtain the texture coordinate information of the vertices of the 3D model, that is, the UV coordinates, and then map the texture (the texture is the data u...
