AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned multi-resolution transparent texture processing method, the smaller-sized layer is processed by image scaling and filtering, resulting in the change of its grayscale information, usually the overall darkening. When rendering in the transparency test mode, the pixel grayscale are likely to be less than the grayscale threshold and be rendered fully transparent rather than fully opaque as desired

Embodiment Construction

[0060] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] refer to figure 1, shows a flow chart of the steps of an embodiment of a texture image processing method of the present invention, which may specifically include the following steps:

[0062] Step 101, obtaining an initial texture map;

[0063] In online games, when the game character moves in the game scene, as the position of the game character changes in the scene, the game scene changes accordingly. In order to make the game scene more realistic, it is often possible to add transparency to the game scene texture.

[0064] When the game character in the game is moving in the game scene, depending on the distance of the viewing angle, the largest image can be displayed at the most prominent position in front...

Abstract

Embodiments of the invention provide a texture image processing method and device. The method comprises the steps of obtaining an initial texture map; generating at least one hierarchical texture mapof the initial texture map; and performing normalization processing on the initial texture map and the at least one hierarchical texture map according to a normalization coefficient to generate at least one corresponding target texture map. Therefore, the normalization processing is performed on the multi-resolution hierarchical texture map, the accuracy of the transparent texture grayscale information is realized, and the problem that the transparent object far away from the viewpoint disappears abnormally in the real-time rendering stage is avoided.

Description

technical field [0001] The present invention relates to the field of image technology, in particular to a texture image processing method and a texture image processing device. Background technique [0002] Multi-resolution texture (Mipmap) is a computer graphics image technology. The combination of multi-resolution texture technology and material mapping technology can convert a single material map into multiple images at different resolutions according to the distance from the viewer. The form manifests itself and represents a flat texture: the largest image is placed prominently in the front, while the smaller images recede into the background area. Multi-resolution texturing prevents unwanted jagged edges (called jaggies) from appearing in images. [0003] A transparency texture is a single-channel grayscale texture usually stored in the Alpha channel of a color texture, with black pixel values ​​representing complete transparency and white pixel values ​​representing c...
