METHOD FOR MAKING A PIXEL BLOCK AND ITS USING APPARATUS AND METHOD FOR BUFFERING

摘要

A method for creating a pixel block and a buffering apparatus and method using the same are provided to create data blocks by unit to create block information, and determine whether to transmit pixel data using the created block information, thereby reducing the amount of data transmission and performing buffering without unnecessary operation. A method for creating a pixel block comprises the following steps of: storing the number of pixels included into a block and the shape information of the block(701); creating pixel blocks based on the reference information(702); generating block information about the block and transmitting the generated block information to a z-buffering apparatus(703); checking whether the z-buffering apparatus requests the transmission stoppage of pixel depth values(704); transmitting the pixel depth values of the block in order if the transmission stoppage of the pixel depth values is not requested(705); and closing the pixel block generation if there is a residual block(706); and selecting a next block if there is the residual block(707).
