Color mixing method and system, computer equipment and storage medium

Abstract

The invention provides a color mixing method and system, computer equipment and a computer readable storage medium. The color mixing method comprises the steps of obtaining a source color, at least one superposition color and a transparency value corresponding to any one superposition color in the at least one superposition color in an image; Rendering for the first time according to the source color and the transparency value to obtain a rendered color value for the first time; Determining an accumulated superposition color according to the at least one superposition color; Determining empirical parameters according to the transparency values; And performing second rendering according to the first rendering color value, the cumulative superposition color and the empirical parameter to obtain an output color value. According to the technical scheme, the determination of the final mixed color can be completed completely without depending on the arrangement sequence of the superposed colors, and the obtained mixed effect is close to the rendering effect obtained by a traditional semitransparent mixing technology.

Description

technical field [0001] The present invention relates to the field of computer graphics, in particular to a color mixing method and system, a computer device and a computer-readable storage medium. Background technique [0002] Translucent mixing (AlphaBlending) is a common color mixing method, and its role is to achieve a translucent effect. Transparency (Alpha) is a type of data that appears in 32-bit bitmap files. It is used to specify the transparency of pixels in the image. That is, by adding a fourth channel, Alpha channel, to the original 24-bit true color file, the file can be Specifies the transparency of each pixel. Alpha set to 0 means transparent, Alpha set to 1 means opaque, values ​​in between means translucent. Translucent mixing is a new color generated by calculating the new color and the old color. The current translucent mixing technology is to multiply the source color and the superimposed color by a coefficient and add them to obtain the output color. ...

Problems solved by technology

Translucent mixing is a new color generated by calculating the new color and the old color. The current translucent mixing technology is to multiply the source color and the superimposed color by a coefficient and add them to obtain the output color. When superimposing multiple colors, each color needs to be superimposed in the order of the superimposed colors, but the traditional calculation method completely depends on the order of the superimposed colors. When the superimposed colors cannot be sorted, such as: for 3D scenes It is very difficult to perform color superposition calculations with traditional translucent mixing techniques
