Abstract

본 발명은 3차원 그래픽 처리를 위한 아핀변환 장치에 관한 것으로, 프레임 단위로 입력되는 초기 3차원 영상데이타가 AT연산부로 입력되어 AT연산되고, AT연산부로부터 출력되는 프레임 단위의 3차원 영상데이타와 지연기에서 지연된 이전 프레임 단위의 3차원 영상데이타와의 차이가 기설정된 소정치 이내이면, 판단기로부터 종료신호가 발생되어 버퍼에 저장되어 있는 프레임 단위의 3차원 영상데이타가 출력되고, 후처리부에서 2차원 이미지로서 좌표변환 되어 모니터에 디스플레이되므로써, 애니매이션 풍경용 3차원 그래픽 처리를 실시간으로 자연스럽게 처리할 수 있도록 한 것이다.The present invention relates to an affine transformation apparatus for 3D graphics processing, wherein the initial 3D image data input in units of frames is inputted to the AT operator and AT-operated, and the 3D image data and delay in units of frames outputted from the AT operator are output. If the difference with the three-dimensional image data of the previous frame unit is delayed within the predetermined value, the end signal is generated from the determiner to output the three-dimensional image data of the frame unit stored in the buffer, the post-processing unit 2 It is transformed as a dimensional image and displayed on a monitor, so that three-dimensional graphic processing for an animated landscape can be processed in real time.
