Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0056] This application provides a texture processing method, apparatus, storage medium, and computer device. Specifically, the texture processing method of this application can be executed by a computer device, which can be a terminal or a server. The terminal can be a smartphone, tablet computer, laptop computer, touch screen, personal computer (PC), personal digital assistant (PDA), or other terminal device.

[0057] For example, the computer device can be a terminal that can acquire a first channel image of a target texture, the first channel image including a target pattern configured with a flashing effect in the target texture; determine the initial brightness of the target pattern; determine the current brightness of the target pattern based on a preset brightness change pattern of the target pattern in the time dimension, the current display duration of the target texture, and the initial brightness; and adjust the brightness of the target pattern in the first channel image according to the current brightness so that the target pattern flashes in the target texture.
[0058] Based on the above problems, this application provides a first texture processing method, apparatus, computer device and storage medium, which can improve the flickering effect of the target texture.
[0059] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the preferred order of the embodiments.
[0060] This application provides a texture processing method, which can be executed by a terminal or a server. This application uses the example of the texture processing method being executed by a terminal for illustration.
[0061] Please see Figure 1 , Figure 1 This is a flowchart illustrating a texture processing method provided in an embodiment of this application. The specific flow of the texture processing method is as follows:
[0062] 101. Obtain the first channel image of the target texture.
[0063] In this embodiment, the target texture refers to an image with special effects, such as flashing. Target textures can be applied in games to add special effects to virtual characters.
[0064] Specifically, a target texture can include multiple channel maps, each with a different function. For example, a target texture can include a first channel map.
[0065] The first channel image includes target patterns configured with a blinking effect in the target texture. There can be multiple target patterns. The multiple target patterns in the first channel image can be the same pattern (patterns with the same shape and size) or different patterns (patterns with different shapes and / or sizes). In actual application scenarios, the designers can set them according to actual needs.
[0066] 102. Determine the initial brightness of the target pattern.
[0067] Initial brightness refers to the initial grayscale value of the target pattern. When generating a target pattern on a target texture, an initial grayscale value can be set for the target pattern.
[0068] In some embodiments, to improve the performance of the target texture, the step "determine the initial brightness of the target pattern" may include the following operations:
[0069] Obtain the position information of the target pattern in the first channel image;
[0070] Based on the location information, a reference pattern corresponding to the target pattern is generated in the second channel image of the target texture.
[0071] Obtain the brightness of the symbolic pattern to get the initial brightness.
[0072] The location information refers to the location points of the target pattern.
[0073] In this embodiment of the application, the target texture may further include a second channel image. The first channel image provides the pattern, and the second channel image provides the brightness. When it is necessary to adjust different attributes of the target texture, different channel images can be selected for adjustment to facilitate operation and avoid affecting other attributes when adjusting one attribute of the target texture.
[0074] Here, the referential pattern refers to the position of the target pattern in the second channel image, and this referential pattern can be used to provide brightness for the target pattern in the first channel.
[0075] For example, please see Figure 2 , Figure 2 This is a schematic diagram illustrating an application scenario of a texture processing method provided in an embodiment of this application. Figure 2 The left image shows the first channel image of the target texture, which includes multiple target patterns: target pattern 1, target pattern 2, target pattern 3, target pattern 4, and target pattern 5. Based on the position of each target pattern in the first channel image, multiple corresponding reference patterns are generated in the second channel image of the target texture. (See [link]). Figure 2 The right-hand image shows that multiple symbolic patterns are generated in the second channel image: symbolic pattern 1, symbolic pattern 2, symbolic pattern 3, symbolic pattern 4, and symbolic pattern 5.
[0076] The correspondence between the target pattern in the first channel diagram and the reference pattern in the second channel diagram is as follows: target pattern 1 corresponds to reference pattern 1, target pattern 2 corresponds to reference pattern 2, target pattern 3 corresponds to reference pattern 3, target pattern 4 corresponds to reference pattern 4, and target pattern 5 corresponds to reference pattern 5.
[0077] Specifically, when generating the referential pattern, an initial grayscale value, i.e., an initial brightness, can be set for each referential pattern. The initial brightness of different referential patterns can be set to be the same or different. In the embodiments of this application, the initial brightness of different referential patterns can be set to be different, thereby enabling different target patterns to flicker at staggered times and ensuring the flickering effect.
[0078] For example, when generating symbolic pattern 1, the brightness value for symbolic pattern 1 is set to 'a'; when generating symbolic pattern 2, the brightness value for symbolic pattern 2 is set to 'b'; when generating symbolic pattern 3, the brightness value for symbolic pattern 3 is set to 'c'; when generating symbolic pattern 4, the brightness value for symbolic pattern 4 is set to 'd'; and when generating symbolic pattern 5, the brightness value for symbolic pattern 5 is set to 'e'. Therefore, the initial brightness of target pattern 1 is determined to be 'a', the initial brightness of target pattern 2 is 'b', the initial brightness of target pattern 3 is 'c', the initial brightness of target pattern 4 is 'd', and the initial brightness of target pattern 5 is 'e'.
[0079] In this embodiment of the application, the brightness can be mapped to the range of 0-1, where 0 can represent black (i.e., the darkest) and 1 can represent white (i.e., the brightest).
[0080] 103. Based on the preset brightness change pattern of the target pattern over time, the current display duration of the target texture, and the initial brightness, determine the current brightness of the target pattern.
[0081] The current display duration of the target texture refers to the duration from the start time of the current display of the target texture to the current time.
[0082] For example, if the start time of the current display of the target texture is 19:00:00 and the current time is 19:00:20, then the current display duration of the target texture can be determined to be 20 seconds.
[0083] The preset brightness variation pattern of the target pattern in the time dimension refers to the brightness at each point in time within a specified time period.
[0084] In this embodiment, the preset brightness variation law can be a preset calculation formula, as follows:
[0085] Y = Sin((Cross_tex.r – 0.5) * parameter 1 + time * parameter 2);
[0086] Where Y refers to the calculated brightness value; Cross_tex.r refers to the initial brightness; Parameter 1 is the period range parameter, which refers to the flashing period of the set target pattern; Time refers to the display duration; Parameter 2 is the flashing speed parameter, which refers to the flashing speed of the set target pattern within the flashing period.
[0087] In some embodiments, to ensure the validity of the brightness value obtained according to the preset calculation formula, the step "determine the current brightness of the target pattern based on the preset brightness change pattern of the target pattern in the time dimension, the current display duration of the target texture, and the initial brightness" may include the following operations:
[0088] The brightness after processing is determined based on the preset brightness change pattern, the current display duration, and the initial brightness.
[0089] The processed brightness is normalized to obtain the current brightness.
[0090] Specifically, the brightness is calculated using a preset formula based on the current display duration and initial brightness. The resulting value is used as the processed brightness, which is then normalized to obtain the current brightness. This ensures that the current brightness remains within the range of 0-1, thus maintaining its validity.
[0091] Specifically, the current brightness refers to the value calculated from the initial brightness based on the current display duration and a preset calculation formula.
[0092] In some embodiments, the step "determine the processed brightness based on a preset brightness variation pattern, the current display duration, and the initial brightness" may include the following operations:
[0093] The first cycle value is determined based on the initial brightness, the first preset value, and the first parameter;
[0094] The second cycle value is determined based on the current display duration and the second parameter;
[0095] The brightness after processing is determined based on the first cycle value and the second cycle value.
[0096] In some embodiments, the step "determine the first cycle value based on the initial brightness, the first preset value, and the first parameter" may include the following operations:
[0097] Calculate the difference between the initial brightness and the first preset value;
[0098] The first period value is obtained by multiplying the difference by the first parameter.
[0099] The value of the first period can be calculated using the following formula:
[0100] (Cross_tex.r–0.5)*parameter1;
[0101] Where Cross_tex.r refers to the initial brightness, 0.5 refers to the first preset value, and the first parameter is also known as parameter 1. Then, based on the initial brightness, the first preset value and the first parameter, the first cycle value is calculated according to the formula: (Cross_tex.r–0.5)*parameter 1.
[0102] For example, if the initial brightness can be 0 and parameter 1 can be 2π, then the first cycle value calculated according to the formula (Cross_tex.r–0.5)*parameter 1 can be -π.
[0103] In some embodiments, the step "determine the second cycle value based on the current display duration and the second parameter" may include the following operations:
[0104] Calculate the product of the current display duration and the second parameter to obtain the second cycle value.
[0105] The value of the first period can be calculated using the following formula:
[0106] Time * parameter 2;
[0107] Here, "time" refers to the current display duration, and "parameter 2" refers to the second parameter. Then, based on the current display duration and the second parameter, the second cycle value is calculated according to the formula: time * parameter 2.
[0108] For example, if the current display duration can be π, and parameter 2 can be 1, then the calculated value of the second cycle can be π.
[0109] In some embodiments, the step "determine the processed brightness based on the first cycle value and the second cycle value" may include the following operations:
[0110] Determine the first sum of the first periodic value and the second periodic value;
[0111] Calculate the trigonometric function value of the first sum to obtain the processed brightness.
[0112] The calculated brightness can be calculated using the following formula:
[0113] Y = Sin((Cross_tex.r – 0.5) * parameter 1 + time * parameter 2);
[0114] Where (Cross_tex.r–0.5)*parameter1 refers to the first period value, and time*parameter2 refers to the second period value, then the formula Y=Sin((Cross_tex.r–0.5)*parameter1+time*parameter2) can be simplified to: Y=Sin(first period value+second period value).
[0115] For example, the first period value can be -π, the second period value can be π, the sum of the first period value and the second period value is 0, then the trigonometric function value of the sum is calculated, that is, Sin(0), and the value obtained is 0, that is, the brightness after processing is 0.
[0116] In some embodiments, the step "normalizing the processed brightness to obtain the current brightness" may include the following operations:
[0117] Calculate the second sum of the processed brightness and the second preset value;
[0118] Calculate the product of the second sum and the first preset value to obtain the current brightness.
[0119] In this embodiment of the application, the normalization of the processed brightness can be calculated according to the following formula:
[0120] (Y+1.0)*0.5;
[0121] Here, 1.0 refers to the second preset value, 0.5 refers to the first preset value, and Y is the processed brightness calculated by the above steps.
[0122] For example, the processed brightness can be 0. Calculating using the formula (Y+1.0)*0.5 yields a value of 0.5, meaning the current brightness is 0.5. This allows for the calculation of the target pattern's current brightness. Adjusting the target pattern's brightness based on this current brightness then creates the flickering effect that occurs as the target pattern changes over time.
[0123] In some embodiments, the first channel image of the target texture may include multiple target patterns. In order to make different target patterns exhibit different flickering effects and highlight the staggered flickering of each target pattern on the target texture, multiple preset brightness change rules can be set. Then, the step "determine the current brightness of the target pattern based on the preset brightness change rules of the target pattern in the time dimension, the current display duration of the target texture, and the initial brightness" may include the following operations:
[0124] Determine the target brightness variation pattern corresponding to the target pattern from multiple preset brightness variation patterns;
[0125] The current brightness is determined based on the target brightness variation pattern, the current display duration, and the initial brightness.
[0126] In this embodiment, the preset brightness variation law is a preset calculation formula: Y = Sin((Cross_tex.r – 0.5) * parameter 1 + time * parameter 2). Here, parameter 1 is the period range parameter, which refers to the flashing period of the set target pattern; time refers to the display duration; and parameter 2 is the flashing speed parameter, which refers to the flashing speed of the set target pattern within the flashing period. By setting parameter 1 or parameter 2 to different values, the flashing period and flashing speed can be made different, thereby enabling different target patterns to achieve different flashing effects based on different preset variation laws.
[0127] Specifically, parameters 1 and 2 can be set for each target pattern to produce different flashing effects for all different target patterns, or parameters 1 and 2 can be set for some target patterns to produce different flashing effects for some target patterns.
[0128] For example, multiple preset brightness variation patterns can include: a first preset brightness variation pattern and a second preset brightness variation pattern.
[0129] In this context, parameters 1 and 2 in the preset calculation formulas corresponding to the first and second preset brightness change rules are different. Multiple target patterns can include: a first target pattern, a second target pattern, a third target pattern, etc. The first target pattern can be preset to correspond to the first preset brightness change rule, and the second and third target patterns can be preset to correspond to the second brightness change rule.
[0130] Furthermore, when adjusting the brightness of the first target pattern, the current brightness of the first target pattern can be calculated according to the first preset brightness change law, and then adjusted; when adjusting the brightness of the second target pattern, the current brightness of the second target pattern can be calculated according to the second preset brightness change law, and then adjusted. In this way, the brightness of each target pattern can be calculated according to the preset brightness change law corresponding to the target pattern, so as to obtain different brightness change effects of each target pattern.
[0131] 104. Adjust the brightness of the target pattern in the first channel image according to the current brightness so that the target pattern blinks in the target texture.
[0132] After calculating the current brightness of the target pattern, the brightness of the target pattern can be adjusted according to the current brightness, so that the brightness of the target pattern changes over time, thereby producing a flickering effect.
[0133] In some embodiments, the current brightness refers to the current brightness of the reference pattern in the second channel image. The display pattern is provided by the first channel image, and the display brightness is provided by the second channel image. A target texture with a flickering effect is generated by combining the first channel image and the second channel image. Then, the step "adjusting the brightness of the target pattern in the first channel image according to the current brightness" may include the following operations:
[0134] The brightness of the target pattern is adjusted based on the current brightness of the reference pattern corresponding to the target pattern in the second channel image.
[0135] In this embodiment, based on the position of the target pattern in the first channel image of the target texture, a reference pattern corresponding to the position of the target pattern is generated in the second channel image of the target texture. The size of the reference pattern is the same as the size of the corresponding target pattern. When generating the reference pattern, an initial brightness is randomly assigned to the reference pattern. Then, based on a preset brightness change rule, the target brightness (i.e., the current brightness) of the initial brightness of the reference pattern at different times is calculated. The current brightness of the corresponding target pattern is determined based on the current brightness of the reference pattern in the second channel image. Then, the brightness of the target pattern is adjusted, thereby achieving the effect of the target pattern flashing in the target texture over time.
[0136] This application discloses a texture processing method, which includes: acquiring a first channel image of a target texture, the first channel image including a target pattern with a blinking effect configured in the target texture; determining the initial brightness of the target pattern; determining the current brightness of the target pattern based on a preset brightness change rule of the target pattern in the time dimension, the current display duration of the target texture, and the initial brightness; and adjusting the brightness of the target pattern in the first channel image according to the current brightness, so that the target pattern blinks in the target texture. This solution sets a first channel image and a second channel image in the target texture. First, multiple target patterns are created in the first channel image. Then, corresponding patterns are generated in the second channel image according to the positions of the multiple target patterns in the first channel image, and the initial brightness of the corresponding patterns is set. The brightness change of the corresponding patterns within a time period is set according to a preset brightness change rule. The brightness change of the target patterns is adjusted according to this brightness change, thereby achieving staggered blinking of different target patterns in the target texture, which can improve the blinking effect of the target texture.
[0137] Based on the above description, the following examples will further illustrate the texture processing method of this application. Please refer to... Figure 3 , Figure 3 This is a flowchart illustrating another texture processing method provided in an embodiment of this application. Taking the application of this texture processing method to a terminal as an example, the specific process can be as follows:
[0138] 201. Obtain the initial texture map containing multiple target patterns.
[0139] In this application, the texture can be applied to a virtual character in a game to create a twinkling star effect. The target pattern can be a star pattern, such as a five-pointed star, a cross, or other star patterns.
[0140] The initial texture refers to an image containing multiple target patterns, which can be arbitrarily distributed within the initial texture.
[0141] 202. Process the initial texture based on multiple target patterns to obtain a composite texture.
[0142] Specifically, processing the initial texture based on multiple target patterns means generating corresponding rectangular patterns in the initial texture based on the positions of the multiple target patterns in the initial texture.
[0143] In this process, the target pattern and the rectangular pattern are located in different channels of the initial texture. For example, the initial texture may include a first channel and a second channel. Multiple target patterns may be located in the first channel of the initial texture, and rectangular patterns may be located in the second channel of the initial texture. The position of each target pattern in the first channel corresponds to the position of each rectangular pattern in the second channel.
[0144] In this embodiment, the Substance Designer software can be used to process an initial texture image containing multiple target patterns to obtain a composite texture image. The specific processing method is as follows:
[0145] First, an initial texture containing multiple target patterns is randomly distributed onto a larger image. Then, at the location of each target pattern, a rectangle with a random grayscale value is generated, large enough to encompass the edge of the target pattern. Next, the first channel containing the target pattern is merged with the second channel containing the rectangular pattern. The first channel can be the G channel of the initial texture, and the second channel can be the R channel of the initial texture. This results in each target pattern in the G channel corresponding to a rectangle in the R channel, representing a different grayscale value.
[0146] 203. Determine the brightness variation pattern of the target image channel in the composite texture based on preset rules.
[0147] In this embodiment of the application, the preset rule is a trigonometric function formula, as follows:
[0148] Y = Sin((Cross_tex.r – 0.5) * parameter 1 + time * parameter 2);
[0149] Here, Cross_tex.r refers to the pixel value of the R channel in the composite texture, that is, the grayscale value. The value of Cross_tex.r is in the range of 0-1; parameter 1 refers to the period range parameter; parameter 2 refers to the motion speed parameter; and time refers to the display duration of the composite texture.
[0150] In the embodiments of this application, the purpose of designing the above trigonometric function formula is to expand the grayscale value of the rectangular pattern of the R channel in the composite texture from 0-1 to the range of -1 to 1, and to make the grayscale value change with time, so that the calculated Y value is the grayscale value that changes with the time period.
[0151] Then, the Y value is processed according to the following formula to ensure its validity:
[0152] (y+1.0)*0.5;
[0153] The Y value is processed again using the above formula so that the resulting value changes over time in the range of 0-1, where 0 can represent black (the target pattern disappears) and 1 can represent white (the target pattern appears).
[0154] 204. Adjust the brightness of the target pattern in the composite texture based on the brightness variation law so that the target pattern in the composite texture blinks, thus obtaining a composite texture with a blinking effect.
[0155] Specifically, after determining the brightness change pattern of the R channel through preset rules, the grayscale value of the rectangular pattern of the R channel changes with time. Then, the grayscale value is multiplied with the target pattern of the G channel, so that the target pattern at the corresponding position of the G channel can be made to flash with time.
[0156] For example, its implementation code can be as follows:

Optionally, the display panel can be configured using a liquid crystal display (LCD), an organic light-emitting diode (OLED), or other similar devices.

Optionally, the touch panel may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller.

It can also receive and execute commands from the processor 501. The touch panel can cover the display panel.

Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuitry 505, converted back into audio data, and output to processor 501 for processing. The audio data is then transmitted via radio frequency circuitry 504 to, for example, another computer device, or output to memory 502 for further processing.
