Abstract

본 발명은 3차원 그래픽 병렬처리를 위한 아핀변환 장치에 관한 것으로, 프레임 단위로 입력되는 3차원 영상데이타가 4×4, 즉 16개의 부블럭으로 분할되어 16개의 AT연산부에서 AT연산이 병렬처리되며, 카운터에서 16개의 AT연산부의 AT연산횟수가 계수되어 기설정된 소정횟수가 되면 카운터로부터 종료신호가 발생되어 16개의 버퍼에 각각 저장되어 있는 부블럭의 3차원 영상데이타가 최종적으로 출력되고, 후처리부에서 2차원 이미지로서 좌표변환되어 모니터에 디스플레이되므로써, 애니매이션 풍경용 3차원 그래픽 처리를 고속으로 처리할 수 있도록 한 것이다.The present invention relates to an affine transformation apparatus for 3D graphics parallel processing, wherein 3D image data input in units of frames is divided into 4 × 4, that is, 16 sub-blocks, so that AT operations are processed in 16 AT operations in parallel. When the AT operation count of the 16 AT calculation units is counted by the counter and the predetermined number of times is set, the end signal is generated from the counter, and the 3D image data of the sub-blocks stored in the 16 buffers is finally output. By transforming the coordinates as a two-dimensional image, and displaying them on a monitor, it is possible to process three-dimensional graphics for an animated landscape at high speed.
