Abstract

The invention discloses a method for multi-layer rendering in a programmable stage in graphics rendering, which specifically includes: budgeting the maximum outline of the beginning and end of special effects, enlarging the object coordinates of the vertices and synchronously enlarging the texture coordinates of the objects; Render in multiple layers and blend the rendered results. The rendering method of the present invention can make full use of the parallelism of the graphics card and improve the rendering efficiency.

Description

technical field [0001] The invention relates to the field of broadcasting and television, in particular to a method for multi-layer rendering with programmable stages in graphic rendering. Background technique [0002] With the continuous development of computer graphics, images, and video technologies, and the domestic broadcasting industry is in the period of transition from standard definition mode to high definition mode, television production and broadcasting units such as TV stations have put forward higher requirements for the production and broadcasting of TV graphics. , Update requirements. It is required to greatly enhance and enrich the broadcast effect of graphics and texts, and show visual impact. [0003] GPU (Graphic Processing Unit, Graphics Processing Unit), a chip computing unit that independently processes computer graphics images. It is precisely because of the superior, flexible processing performance and highly parallelized processing capabilities of ...
