Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] A configurable fast texture compression method such as figure 1 shown, including:

[0020] Step 1, the texture image division module (1) parses the texture image data, converts the texel data according to the texture format of the image, and divides the texture image into a series of texture cells according to the size of the texture image, and sends them to the reference color screening module ( 2);

[0021] Step 2, the user configuration module (5) accepts the user configuration parameters, sets the reference point selection method and the number of reference points of the reference color pre-screening module (2)...

Abstract

The invention belongs to a field of computer graphs and especially relates to a configurable quick texture compressing method. The method includes a step 1, a texture picture dividing module (1) analyzes texture picture data and divides the texture picture into a series of texture cells and sending the texture cells into a reference color screening module (2); a step 2, a user configuration module (5) receives user configuration parameters; a step 3, a reference color pre-screening module (2) receives a reference point selecting method and a reference point number set by the user configuration module (5) and sets the reference point selecting method and the reference point number as a pre-screening strategy. According to the invention, through dividing the texture picture into cells, performing pre-screening of reference colors in the cells according to the user configuration information, determining texture compression reference colors according to cell error factors and generating compression texture data through combination, the texture compression process can be implemented quickly and efficiency in a configurable manner.

Description

technical field [0001] The invention belongs to the field of computer graphics, in particular to a configurable fast texture compression method. Background technique [0002] Texture compression is a popular technology for 3D scene rendering, which can improve the transmission efficiency of texture data in complex scenes. Greatly reduce texture transmission and storage space, speed up texture mapping, and improve graphics processing capabilities. However, traditional image compression algorithms cannot flexibly configure and select texture compression strategies according to user needs, which reduces the configurability of the texture compression process. This paper proposes a configurable fast texture compression method under the condition of selecting a reference color. Contents of the invention [0003] The purpose of the present invention is: [0004] The present invention mainly provides a configurable fast texture compression method, which can configurably, quickly...
