Texture coordinate calculation method and device

Abstract

An embodiment of the invention provides a texture coordinate calculation method and device. The method includes acquiring space coordinates of different vertexes and different distribution points in each grid quadrangle corresponding to a road model in a current game scene; based on the space coordinates of different vertexes and different distribution points in the same grid quadrangle, performing calculation on transformation coefficients in a transformation equation of the different distribution points between space coordinates and texture coordinates; according to the transformation equation and the acquired transformation coefficients corresponding to the different distribution points, calculating texture coordinates of the distribution points in a road texture mapping. The method provided by the invention is high in calculation precision. The texture coordinates of different points in an grid quadrangle of any shape can be calculated accurately, mapping error rate can be reducedand sensation experience of players can be improved.

Description

technical field [0001] The present invention relates to the technical field of game scene processing, in particular to a method and device for calculating texture coordinates. Background technique [0002] In 3D games, the road is an important part of the game scene, and the road generation needs to obtain the texture coordinate data of the road model on the corresponding road texture map, so as to map each texel in the road texture map to the road model at the corresponding position on the map to complete the road generation process. Among them, how to obtain high-precision texture coordinate data is an extremely important issue. [0003] In the prior art, the commonly used texture coordinate calculation method is to calculate the texture coordinates according to the distance from the points on the grid to the surrounding cut planes when the road model is meshed. The calculation accuracy of this calculation method is not high, and it needs to be divided The overall shape ...

[0003] In the prior art, the commonly used texture coordinate calculation method is to calculate the texture coordinates according to the distance from the points on the grid to the surrounding cut planes when the road model is meshed. The calculation accuracy of this calculation method is not high, and it needs to be divided The overall shape of the grid is in a very regular state, otherwise the texture coordinates of different points in the grid cannot be calculated, and mapping errors are likely to occur during texture mapping, which will affect the player's sensory experience
