<p>A graphics texture data encoding arrangement in which the texels in a texel block 30 to be encoded are divided into different partitions within the block. A reference partitioning pattern for a texel block to be encoded is then generated using a partitioning function 32 such a lloyd s algorithm or other k-means clustering algorithms, to partition the data values for the texels into a number of data value partitions. The individual texels in the texel block are then sorted into respective partitions based on their values to provide a reference partition pattern. A set of predefined partitioning patterns 35 that the encoding scheme supports is then compared 36 to the generated reference partitioning pattern using a similarity measure such as Hamming distance and the predefined partitioning pattern that best matches 39 the generated reference partitioning pattern is then used 42 to encode the block of texels. The encoded texture data may be stored in the form of mip-maps</p> |
