A method for mixed processing of graphics and images in 2D and 3D environments

Abstract

The invention discloses a graph picture mixed processing method in two-dimensional and three-dimensional environments. The graph picture mixed processing method comprises obtaining respectively different graph picture mixed processing methods aiming at the two-dimensional and three-dimensional environments; enabling the respectively different graph picture mixed processing methods aiming at the two-dimensional and three-dimensional environments to generate different dynamic depots respectively; judging whether current image mixed processing application aims at the two-dimensional environment or the three-dimensional environment, invoking a graph picture mixed method in the corresponding dynamic depots and conducting mixed processing. By means of the method provided by an embodiment of the graph picture mixed processing method, graph picture mixing in the three-dimensional environment is solved, black edge situations produced by a peripheral edge are solved, graph picture mixing in the two-dimensional environment is solved, distortion situations such as content and shape changes are avoided, a scheduling problem between different methods of the graph picture mixing under two-dimensional and three-dimensional coexisting environments is effectively solved, and system overhead and program running time are greatly reduced.

Description

technical field [0001] The present invention relates to the field of radio and television, in particular to a method for mixed processing of graphics and images in two-dimensional and three-dimensional environments. Background technique [0002] Under certain mixing rules, the source and target pixels are mixed to make the resulting scene more realistic. For the mixing operation, a simple understanding is to regard the RGB component of a pixel as its color, and the Alpha component as its transparency. Transparent and translucent surfaces are less opaque than opaque surfaces, that is, they have a lower alpha value than opaque surfaces. For example, if we look at an object through green glass, the color we see comes partly from the green of the glass and partly from the color of the object. The proportion of these two colors depends on the relay properties of the glass, as well as the transparency of the object. [0003] In the process of realizing the present invention, th...
