In the game scene making process, a stylized map drawn by an artist is often required. The artwork may be manually drawn by an artist or may be drawn using photoshop software.
The drawing of the stylized image specifically refers to simulating a drawing process of the stylized image using a computer, and generating a corresponding stylized image based on the original input image. The existing image stylized drawing method is mainly a layering method based on layer-by-layer drawing, the main idea is to simulate the classification of rough-to-fine image textures generated by painters in the heart, generally, a large brush and a large blending color block are used for drawing rough outlines, then a small brush is used for gradually and gradually carrying out finer drawing, and the method is a layer-by-layer drawing process from thick to thin.
However, due to the aesthetic level of different art personnel, the colors and the pen touch effects of the drawn stylized drawings are uneven, and the uniformity of the effects cannot be achieved.
In response to this problem, the present disclosure proposes a map making method.
It should be noted that, in the exemplary embodiment of the present disclosure, the mapping method described below may be implemented by a terminal device (e.g., a mobile phone, a tablet, a personal computer, etc.), that is, each step of the mapping method may be performed by the terminal device, in which case the mapping apparatus may be configured in the terminal device.
The steps of the mapping method in the present exemplary embodiment will be described in more detail with reference to the accompanying drawings and examples.
Fig. 1 schematically shows a flow chart of a mapping method of an exemplary embodiment of the present disclosure. In the following illustration, an illustration is made with a terminal device as an execution subject. Referring to fig. 1, the mapping method specifically may include the following steps:
s102, acquiring a first pixel block and a second pixel block.
In an exemplary embodiment of the present disclosure, the first pixel block and the second pixel block may be obtained by computer software by setting a pixel size. The first pixel block and the second pixel block have the same pixel size. The present disclosure may use the Pixel Processor node edit function in texture software substance designer to get 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 present disclosure sets Pixel blocks of 8 x 8 pixels in substance designer Pixel Processor node edit functions.
The method and the device can display the first pixel block and the second pixel block in UV coordinates, and determine the position of each pixel in the pixel blocks.
S104, performing a product processing process on the first pixel block and the second pixel block and the corresponding color disturbance parameters respectively.
The color disturbance parameters may include color diffusion parameters, color variation parameters, and color key parameters. The range of values of each of the color disturbance parameters may be set at [0,1]. Color diffusion parameters can be used to control the extent of diffusion and influence of color. The color change parameter may be used to control the degree of color change. The color key parameters may be used to control the propensity of the base color.
The color diffusion parameters, the color change parameters and the color key parameters in the color diffusion and color change display device belong to configurable parameters, can be adjusted according to drawing requirements of actual mapping, avoid different mapping color effects produced by different aesthetic staff, and improve the uniformity of the mapping color effects. Meanwhile, the target mapping is obtained based on the first pixel blocks and the second pixel blocks which are the same in size and different in initial data, so that the intellectualization and automation of the halation dyeing color mapping are improved, the mapping manufacturing cost is reduced, and the mapping manufacturing yield is improved.
As shown in fig. 3, in substance designer, a color Diffusion node 302 (Diffusion) may be used to configure a color Diffusion parameter, which may limit the Diffusion range of random values in a pixel block; color change parameters may be configured with Color change node 304 (Color change); color key parameters may be configured with color key point 306 (Basecolor).
The color key parameters may include color parameters of three color channels of Red (Red, R), green (Green, G), and Blue (Blue, B) in the pixel block.
The present disclosure is directed to three color channels of Red (Red, R), green (G), blue (B), the RGB channels being based on a gray scale of 0-1, which, upon superposition, produce various colors. The color perturbation interval for each pixel block of the present disclosure may be a random value between [ -1,1 ]. The color diffusion parameters may be generated by a pseudo-random function corresponding to the pseudo-random function node 308 (GlobalRandom). The pseudo-random function 308 may generate a floating random value between 0 and a preset input value.
According to an exemplary embodiment of the present disclosure, the terminal device may first determine a separation distance corresponding to the first pixel block; then, based on the interval distance, adjusting the distance between adjacent pixels in the first pixel block to obtain an adjusted first pixel block; and then, performing a product processing process on the adjusted first pixel block and the second pixel block and the corresponding color disturbance parameters respectively.
After the terminal device obtains the first pixel block, the size of the first pixel block can be determined. The separation distance may be used to separate pixels in the first pixel block. For example, the size of the first pixel block is 8×8 pixels, the terminal device may determine that the interval distance corresponding to the first pixel block is a value greater than 8, and the interval distance may be set to 16.
As shown in fig. 4, in the interface of substance designer, the pixel position in the horizontal direction of the corresponding first pixel block is multiplied by the separation distance 16 and the pixel coordinates in the vertical direction are multiplied by the separation distance 16 in the position node 401 ($pos) of the first pixel block such that adjacent pixels in the first pixel block are separated.
In UV coordinates, the present disclosure may separate adjacent ones of the first pixel blocks along the UV coordinate axes, respectively. The distance interval that can separate adjacent pixels in the first pixel block at this time is within the scope of the present disclosure. The distance between adjacent pixels in the first pixel block may be set to the same value or may be set to different values. The present disclosure separates adjacent pixels in a first pixel block, avoiding the same color from being adjacent, resulting in a first pixel block containing pixels of different colors. As shown in fig. 4, X may represent a U coordinate axis in UV coordinates and Y may represent a V coordinate axis in UV coordinates.
According to another embodiment of the present disclosure, the terminal device may first perform shift processing on each pixel in the first pixel block according to the color diffusion parameter; then, carrying out product processing on the shifted first pixel block, the color change parameter and the color key parameter; then, the second pixel block is multiplied by the color diffusion parameter.
The terminal device can enable each pixel in the first pixel block to be randomly shifted based on the color diffusion parameter, and can reversely adjust the color of the pixel.
As shown in fig. 3, in the interface of substance designer, the terminal device first adjusts the distance between the adjacent pixels in the first pixel block and multiplies the adjusted distance by the random value generating node 314; then, according to the color diffusion parameters corresponding to the color diffusion nodes 302, performing random shift processing on each pixel in the first pixel block; second, color inverting the randomly shifted first pixel block based on the inverse color node 310 (One Minus); then, the product processing is performed on the first pixel block, the color variation parameter corresponding to the color variation node 304, and the color base parameter corresponding to the color base node 306, so as to obtain a first pixel block varying in the [ -1,1] interval.
The terminal device, in performing random shift processing on each pixel in the first pixel block according to the color diffusion parameter corresponding to the color diffusion node 302, may further include:
First, the 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, so as to obtain the numerical range of the color diffusion parameter.
Substance designer includes a decimal node 312 (frac) in the interface that can be used to return the decimal portion of the random value.
After determining the size of a first pixel block, the method performs a product processing process on RGB color key parameters, color diffusion parameters and pseudo-random functions of each pixel in the first pixel block, and then obtains three RGB color channel parameters of each pixel in the first pixel block after the product processing. The three RGB color channel parameters may also be converted to parameters expressed in terms of hue, saturation, and brightness by rgb_hsl mode conversion nodes (Hue Saturation Lightness, HSL). The present disclosure may also convert HSL color channel parameters to parameters represented in three aspects, red, green, blue, by the hsl_rgb mode conversion node.
As shown in fig. 5, in the interface of substance designer, the terminal device may first establish a random value of 0-1 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; the second pixel block is then multiplied by the color diffusion parameter corresponding to the color diffusion node 302.
S106, performing superposition processing on the first pixel block and the second pixel block after the multiplication processing to obtain a candidate map.
After obtaining 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 an intermediate pixel block; and then, performing preset pixel doubling processing on the middle pixel block after the superposition processing to obtain a candidate map.
Specifically, the present disclosure may perform superposition processing on each pixel in the second pixel block after the product processing and a pixel in a corresponding position in the first pixel block, to obtain an intermediate pixel block. That is, the color corresponding to each pixel in the intermediate 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 intermediate pixel block may be the same as the size of the first pixel block and the size of the second pixel block.
In an exemplary embodiment of the present disclosure, the present disclosure determines a candidate map by performing a product process and a superimposition process on a first pixel block and a second pixel block, determines a partial map corresponding to a gray scale extraction parameter from gray scale maps corresponding to the candidate map, and generates a target map according to the partial map. Avoids relying on artistic staff to make the map and improves the intellectualization and automation of the halation dyeing color map.
As shown in fig. 5, the terminal device first performs superposition processing on the pixels at the positions corresponding to the position nodes 401 of the second pixel block and the first pixel block after the product processing, so as to obtain an intermediate pixel block, where the size of the intermediate pixel block is 8×8. And then, the terminal equipment performs preset pixel doubling processing on the middle pixel block subjected to the superposition processing to obtain a candidate map. The size of the candidate map is 1024×1024 pixels, as shown in fig. 6.
S108, determining a partial map corresponding to the gray extraction parameters from the gray maps corresponding to the candidate maps, and generating a target map according to the partial map.
In an exemplary embodiment of the present disclosure, the gray scale map may be a candidate map converted by the terminal device through the gray scale conversion node. As shown in fig. 7, the terminal device converts the candidate map with size 1024×1024 pixels into a gray map through the gray conversion node 704 (GRAYSCALE CONRERSION).
The gray scale extraction parameter may be a gray scale extraction parameter corresponding to the color of the map to be generated. The gray scale extraction parameters may also include pixel gray scale values corresponding to each color channel in the map to be generated. The present disclosure may determine gray scale extraction parameters based on the needs of the actual scene.
According to an exemplary embodiment of the present disclosure, the terminal device may first convert the candidate map into a grayscale map; then, based on the gray scale extraction parameters, determining pixel gray scale values corresponding to all color channels in the to-be-generated map, and taking the pixel gray scale values as target pixel gray scale values; and then, according to the gray value of each pixel in the gray map and the gray value of the target pixel, determining a partial map corresponding to the gray extraction parameter, and generating the target map according to the partial map.
The target map may contain only the color pixel blocks corresponding to the target pixel gray values, and the target map may be the same size as the candidate map. The target map may be a color map determined according to an actual color requirement, or may be a map obtained by doubling a pixel block corresponding to a part of the map.
According to another embodiment of the present disclosure, the terminal device may first determine a pixel gray value of each color channel in the gray map as a comparison pixel gray value; then, respectively calculating gray difference values of the gray values of the comparison pixels and the gray values of the target pixels in the color channels; and then, determining a part of the mapping corresponding to the gray value of the comparison pixel with the gray difference value in the difference range as a target mapping.
After the gray map is obtained, the terminal device may further perform a non-uniform blurring process on the gray map to obtain a gray map from which noise is removed. The present disclosure performs a non-uniform blurring process on a grayscale map such that transitions of similar colors in a target map are smoothed.
The comparison pixel gray value may refer to a pixel gray value of each color channel in the gray map, and may be used for comparing with a target gray value. The contrast pixel gray value may comprise a target gray value. The terminal device may compare the comparison pixel gray value with the target pixel gray value, determine the target gray value from the comparison pixel gray value, and further determine a partial map corresponding to the target gray value.
As shown in fig. 7, in the interface substance designer, when the terminal device obtains the candidate map, firstly, the corresponding pixel block in the node editing function 702 of the candidate map is input into the gray level conversion node 704 to obtain the gray level map; then, a gray map with noise removed can be obtained through Non-uniform blur nodes 706 (Non uniform blue); secondly, the terminal equipment can determine the pixel gray value corresponding to each color channel in the map to be generated based on the gray extraction parameter, and the pixel gray value is used as a target pixel gray value; again, the gray differences of the gray values of the comparison pixels in the respective color channels and the gray values of the target pixels may be calculated, respectively, and then, a partial map corresponding to the gray values of the comparison pixels having the gray differences within the difference range may be determined as the target map.
The terminal device may also determine the partial map corresponding to the target pixel gray value from the gray map through the gray range selection node 708 (Histogram selection), then determine the foreground layer region shape of the map to be generated through the model node 710 (shape) and the gray blurring node 712 (Blur HQ GRAYSCALE), and then input the partial map corresponding to the target pixel gray value of the foreground layer region shape (as a background layer) into the mixed mode node 714 (Blend) to obtain the target map 716 (Alpha map). The enlarged Alpha map is shown in FIG. 8.
The terminal device may further obtain an intelligent material ball composed of colors corresponding to the Alpha map based on the generated Alpha map, as shown in fig. 9.
The method and the device can determine the partial mapping corresponding to the gray extraction parameters from the gray mapping corresponding to the candidate mapping, and generate the target mapping according to the partial mapping, so that different color effects of mapping manufactured by different aesthetic persons are avoided, and the color effect unification of the mapping is improved.
