wherein the plurality of initial curves may have the same line width, e.g. 40 μ.

In practical applications, a plurality of initial curves can be created in the drawing software, and the plurality of initial curves can have different curvatures and can have the same line width.

Substep 12, respectively performing line width adjustment on the plurality of initial curves to obtain a plurality of target curves;

since the line width of each initial curve is the same, the line width of each initial curve can be adjusted to obtain a target curve, and the line width of each target curve is changed in a width-width staggered manner, as shown in fig. 2, that is, a first region and a second region which alternately appear can exist in each target curve.

Wherein a line width of the first region may be greater than a line width of the second region.

In one example, each target curve may have a different curvature.

Substep 13, relatively arranging the target curves according to different radians;

the line widths of the first areas in the two adjacent target curves are sequentially increased.

After the target curves are obtained, the target curves can be arranged oppositely by adopting different radians, so that the line widths of the areas with opposite positions between the two adjacent curves are sequentially increased.

In one example, as shown in fig. 3, the plurality of target curves may be arranged with the same line spacing, i.e. the distance between the centers of two target curves arranged adjacently is the same, such as 60 μ.

And a substep 14, arranging the target curves to form a plurality of peaks, and obtaining the UV texture.

Wherein the plurality of peaks may have different slopes.

In a specific implementation, multiple target curves may be arranged to form multiple peaks, for example, 3 peaks, and then a UV texture may be obtained, as shown in fig. 4.
