To address this problem, the present disclosure provides a method for making a map.

Hereinafter, each step of the map making method in the present exemplary embodiment will be described in more detail with reference to the drawings and examples.

In an exemplary embodiment of the present disclosure, the first pixel block and the second pixel block may be obtained by setting a pixel size by computer software. The first pixel block and the second pixel block have the same pixel size. The present disclosure may use the Pixel Processor node editing function in the texture production software substance designer to obtain the Pixel blocks. The terminal device may set a first pixel block and a second pixel block of 8 x 8 pixels. As shown in fig. 2, the Pixel Processor node editing function of the present disclosure sets a Pixel block of 8 × 8 pixels in the substance designer.

The value range of each parameter in the color disturbance parameters can be set to [0,1 ]. The color diffusion parameter may be used to control the diffusion of color and the range of influence. The color change parameter may be used to control the degree of color change. The color key parameter may be used to control the propensity of the base color.
The color diffusion parameter, the color change parameter and the color key parameter belong to configurable parameters, and can be adjusted according to the drawing requirements of the actual chartlet, so that different chartlets are prevented from making different chartlets, and the color effect unification of the chartlets is improved.

The present disclosure is directed to three color channels, Red (R), Green (G), and Blue (B), where the RGB channels are based on 0-1 gray scale, and produce various colors after superposition. The color perturbation interval of each pixel block of the present disclosure may be a random value between [ -1,1 ]. The color diffusion parameter may be generated by a pseudo-random function corresponding to pseudo-random function node 308 (GlobalRandom). The pseudo-random function 308 may generate a floating random value between 0 and a preset input value.

In the UV coordinate, the present disclosure may separate adjacent pixel blocks in the first pixel block along the UV coordinate axis, respectively. The distance interval at which the first pixel block can be separated by adjacent pixels falls within the scope of the present disclosure. The spacing distances between adjacent pixels in the first pixel block may be set to the same value or different values. The adjacent pixels in the first pixel block are separated, the adjacent pixels with the same color are avoided, and the first pixel block containing the pixels with different colors is obtained. As shown in fig. 4, X may represent a U coordinate axis in the UV coordinate, and Y may represent a V coordinate axis in the UV coordinate.

The terminal device may further perform, in the random shift processing on each pixel in the first pixel block according to the color diffusion parameter corresponding to the color diffusion node 302, the step of:
first, a product processing is performed on the color diffusion parameter corresponding to the color diffusion node 302 and the pseudo-random function corresponding to the pseudo-random function node 308 to obtain a numerical range of the color diffusion parameter.
The substance designer interface includes a fraction node 312(frac) that may be used to return the fractional part of the random value.
After the size of the first pixel block is determined, a product processing process is executed aiming at the RGB color key parameters, the color diffusion parameters and the pseudorandom functions of all the pixels in the first pixel block, and then three RGB color channel parameters of all the pixels in the first pixel block after the product processing are obtained. The three RGB color channel parameters may also be converted into parameters expressed in terms of Hue, Saturation, and brightness by a RGB _ HSL mode conversion node (HSL). The present disclosure may also convert the HSL color channel parameters into parameters expressed in three aspects of red, green, and blue through the HSL _ RGB mode conversion node.
As shown in fig. 5, in the interface of the substance designer, the terminal device may first establish a random value of 0 to 1 in the UV coordinate direction, and divide the random value by 8 × 8 pixels corresponding to the pixel block size node ($ size)502 to obtain a second pixel block; and then the second pixel block is multiplied by the color diffusion parameter corresponding to the color diffusion node 302.
And S106, performing a superposition processing process on the first pixel block and the second pixel block after the product processing to obtain a candidate mapping.
After the terminal device obtains the first pixel block and the second pixel block after the product processing, the terminal device may first perform superposition processing on the first pixel block and the second pixel block after the product processing to obtain a middle pixel block; and then, carrying out preset pixel doubling treatment on the middle pixel block after the superposition treatment to obtain a candidate mapping.
Specifically, the method and the device can perform superposition processing on each pixel in the second pixel block after the product processing and the pixel at the corresponding position in the first pixel block to obtain a middle pixel block. That is, the color corresponding to each pixel in the middle pixel block is obtained by superimposing the color corresponding to each pixel in the second pixel block and the color corresponding to the pixel at the corresponding position in the first pixel block.
In an exemplary embodiment of the present disclosure, the size of the middle pixel block may be the same as the size of the first pixel block and the size of the second pixel block.

And then, the terminal equipment performs preset pixel doubling processing on the middle pixel block after the superposition processing to obtain a candidate mapping. The size of the candidate map is 1024 x 1024 pixels, as shown in fig. 6.
