Layered vertex coloring method

Abstract

The invention discloses a layered vertex coloring method which comprises the following steps: S1, a coloring model of an embryoid body to be subjected to vertex coloring is obtained, and a coordinate is established for each color spot on the surface of the coloring model and hue is labeled; S2, a reference plane which is arranged opposite to the color model and positioned on the periphery of the color model is established, and each color spot has a corresponding spot on the reference plane; S3, the distance value of the color spot relative to the corresponding spot is obtained; S4, classification of color spots is carried out according to the distance value and hue, and color spot and hue are the same in the same class and the maximum error of distance value is not more than preset feed floating threshold; S5, vertex coloring paths are generated for each class according to the color spot classification result; and S6, the embryoid body to be subjected to vertex coloring undergoes coloring according to the vertex coloring paths. Through the mutually independent vertex coloring paths, mutual interference of color spots at different layers and with different hues is avoided during the coloring process of the embryoid body to be subjected to vertex coloring, coloring qualified rate is raised, and color quality is enhanced.

Description

technical field [0001] The invention relates to the technical field of engraving coloring, in particular to a layered point coloring method. Background technique [0002] Red wine engraving is to present text, characters, photos of various items, vector graphics, trademarks and other patterns on the red wine bottle through engraving, and then use the process of coloring at room temperature to make a contrasting color with the dark brown background of the red wine bottle. It embodies a complete, fine and bright pattern. [0003] At present, the commonly used coloring method is to use color nozzles for color spraying, but color spraying is relatively large in a single coloring area, and it is impossible to fine-tune the color transition part, so it is difficult to achieve the expected effect. In particular, the area of ​​the red wine bottle itself is small, and it is difficult to meet the exquisiteness of the pattern by using the existing color spray technology. Contents of...
