ABSTRACT:
Methods, apparatus and computer program products for applying texture to the surfaces of objects in graphics images utilizing texture patterns organized into blocks of texels. Each block of texels is preferably compressed using a block-oriented compression technique and then compressed further using entropy coding. Multiple processing elements rendering an image make requests for texels by address. The texel addresses are converted to block addresses, and the block addresses are consolidated and redundant requests are eliminated. The blocks are retrieved from texture pattern memory, performs entropy decoding, and transfers the data to the processor array such that the likelihood of redundant retrieval of texture data is reduced. The processing elements utilize the retrieved texture data for calculation of pixel values utilizing the texture information.
