Problems solved by technology

[0005] In the existing technology, the texture is divided into blocks and a certain reference point is set, and the whole texture block is encoded by the reference point to compress the texture. This scheme provides a configurable texture compression method. However, due to the use of reference point coding, it is a lossy compression

Abstract

The invention relates to the technical field of computer graphics, in particular to a hardware-friendly lossless texture compression algorithm for a real-time system, which comprises the following steps of: dividing a texture to be compressed into a plurality of data blocks with fixed sizes by a data cutting module, and sending the data blocks into a data compression module; enabling the data compression module to perform Huffman compression and 1z77 compression on a plurality of data blocks with fixed sizes; and after compression is completed, comparing the size of the compressed data packetwith the size of the original data packet; if the size of the compressed data packet is smaller than the size of the original data packet, adding a compressed file header when the compressed data packet is output, and otherwise, outputting the original data and not compressing the data. The method has the advantages that the texture to be compressed is divided into the data blocks with the fixedsize, the fixed blocks are compressed through Huffman compression and lz77 compression, the problem that lossless compression and decompression are difficult is solved, the purpose of lossless texturedecompression is achieved, and the data blocks with the fixed size are friendly to hardware during decompression.

Description

Technical field [0001] The invention relates to the technical field of computer graphics, in particular to a hardware-friendly lossless texture compression algorithm for real-time systems. Background technique [0002] Texture compression is a form of image compression dedicated to storing texture maps in three-dimensional computer graphics rendering systems. Texture compression technology can not only improve the utilization efficiency of texture cache, and make it possible to use larger and higher resolution textures, and the use of larger and higher resolution texture images will make the surface of the scene in the virtual environment look more Real and delicate: It can more effectively reduce the burden of system data transmission and avoid the system performance degradation caused by frequent exchange of texture buffers. This balances the real-time rendering of realistic graphics to a certain extent. [0003] The difference between texture compression and other image compres...
