Texture processing method and electronic equipment

Abstract

The invention discloses a texture processing method applied to a piece of electronic equipment including a first processing unit and a second processing unit. The method comprises: the first processing unit transmits a first texture having a first coding format to the second processing unit, wherein the first coding format does not belong to a texture coding format supported by the electronic equipment; the second processing unit decodes the first texture to obtain corresponding first texture color data; and the second processing unit codes the first texture color data to obtain a second texture having a second coding format that is a texture coding format supported by the electronic equipment. In addition, the invention also provides electronic equipment for texture processing. With the method and electronic equipment, the texture for cross-platform code usage is realized under the circumstances that the CPU resource consumption is reduced and the operating speed is increased.

Description

technical field [0001] The present invention relates to the field of image data processing, and more specifically, to a texture processing method and device. Background technique [0002] Texture is an image pixel format defined in computer graphics, which can be recognized by an embedded GPU (graphics processing unit), and can be quickly addressed and sampled. Texture mapping is a commonly used method in the field of image data processing. As a bitmap attached to a 3D object, texture mapping can obtain realistic surface details without increasing the complexity of the geometry in the 3D scene, such as wood grain, Marbles are all the way to complex graphics such as characters, buildings, trees, etc. Therefore, simulating fine and complex scenes, such as the screen scenes in video games, usually requires a large number of texture maps to achieve, but these texture maps will take up a lot of system memory or video memory , taking a texture with a size of 512*512 as an example...

AI Technical Summary

Problems solved by technology

[0004] In current games on mobile devices, texture encoding is usually done using the ETC1 format supported by the GPU of the mobile device, in order to reduce the memory consumption of the mobile device. Experience, mobile device game simulators (such as various Android simulators for Android mobile games) on the PC side (such as desktop computers) emerged as the times require, but correspondingly, problems have arisen: using mobile devices such as GPUs supported by mobile phones format-encoded textures that cannot be used cross-platform by desktop GPUs

[0006] One method is to use the central processing unit (CPU) of the desktop computer to encode the texture supported by the GPU of the mobile device, and then transmit it to the GPU on the PC side after decoding, but the decoding will consume a lot of resources of the CPU, and the speed is slow, and the decoded Textures will occupy a large amount of CPU memory, and correspondingly will occupy a large amount of display storage after being sent to the GPU, resulting in programs that expect to use textures encoded in formats supported by the mobile device GPU on desktop computers (such as mobile phones running in Android emulators) games), running slowly or freezing, affecting user experience

[0007] Another method is to improve based on the aforementioned method. After the CPU of the desktop computer decodes the texture encoded in the format supported by the GPU of the mobile device, it encodes it in a texture format supported by the desktop computer, and then transmits the encoded texture to The GPU of the desktop computer is used, but this method can save the display storage of the GPU of the desktop computer, but after decoding and then encoding in the CPU of the desktop computer, the CPU resource consumption is larger than the previous method. In the CPU It takes longer, and it will also cause applications that expect textures encoded in formats supported by the mobile device GPU on desktop computers (such as mobile games running in Android emulators) to run slowly or freeze, affecting user experience
