Data render method and device

Abstract

The invention discloses a data render method and a device. The data render method comprises the steps of reading and storing frame data collected by a video card, changing the data structure of the frame data when the data structure of the frame data is interleaved data, combining frame data in lines of odd number together, enabling the combined frame data in the lines of the odd number to be served as odd-number data, combining frame data in lines of even number together, enabling the combined frame data in the lines of the even number to be served as even-number data, and carrying out data rendering on the frame data according to output needs. According to the data render method and the device, through combination of the odd-number data and the even-number data of the interleaved data, the odd-number data are read and rendered when the odd-number data need to be rendered, the even-number data are read and rendered when the even-number data need to be data rendered, due to the fact that data conversion process line by line is not conducted on the interleaved data, the phenomenon of sawteeth and glint when a rendering picture is output is avoided, meanwhile, occupancy amount of resources of a central processing unit (CPU) is reduced, and efficiency of three-dimensional real-time render is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a data rendering method and device. Background technique [0002] With the continuous development of 3D real-time rendering technology, 3D real-time rendering technology has also been applied to the field of broadcasting and television, and then a 3D online packaging system has emerged. The 3D packaging system consists of a computer, video card and rendering equipment. The computer provides the operating platform of the entire 3D packaging system. The video card provides the input and output of the video screen and realizes the fast mixing function between video and graphics. The rendering device is the core of the whole system. , An interactive tool to control the operation and output of the video card. [0003] There are many kinds of video cards, and the video signals collected by the rendering device through the video card are also divided into many types, ...
