[0021] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0022] With the development of special effects rendering technology, special effects often need to be layered to achieve better visual effects. For example, a dozen or even twenty layers of planar special effects may be layered to express a cool effect, which may lead to a large performance load when rendering special effects. Furthermore, for special effects in older versions, it is not possible to optimize the rendering of special effects by layering, which may result in the loss of HDR information of the special effects.

[0023] The special effects rendering method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or located in the cloud or on other network servers. Server 104 is used to execute the special effects rendering method. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. Portable wearable devices can include smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0024] To address the aforementioned problems, in one embodiment of this application, such as Figure 2 As shown, a special effects rendering method is provided, including the following steps:

[0025] Step 201: Obtain the target effect to be rendered.

[0026] The target effect includes multiple particles and the corresponding attribute parameters for each particle.

[0027] It should be noted that the target special effect is the special effect that needs to be rendered. In this embodiment, steps 201 to 203 are the preprocessing process for the target special effect to be rendered. Special effects refer to the visual effects and illusions created in the production of media such as movies, television, dramas, and video games through special technical means and skills. These effects are either too dangerous or too costly to be directly filmed in real life. The target special effect includes multiple particles and the corresponding attribute parameters of each particle. The particle is the smallest basic unit that constitutes the target special effect. By using computer software, all data in the three-dimensional scene, including models, textures, lighting, animation, and special effect simulations, are processed through complex calculations to finally obtain the attribute parameters of each particle that makes up the target special effect. The attribute parameters include the particle's position parameters, color parameters, and material parameters. The position parameter is used to characterize the particle's position, the color parameter is used to characterize the particle's color, and the material parameter is used to characterize the particle's material.

[0028] Step 202: Based on the preset baking perspective, draw the target effect on a blank image in the first image format to obtain a texture image.

[0029] The preset baking view is a pre-set baking perspective, which can be used to draw the target effect. In this embodiment, the first image format is RGBAHalf format.

[0030] Specifically, based on a preset baking perspective and the attribute parameters corresponding to each particle, the target effect is drawn on a blank image in a first image format to obtain a texture image.

[0031] Baking, also known as "texture baking" or "light baking", is based on the idea of ​​pre-calculating time-consuming and dynamic results and storing them on one or more texture maps so that these results can be quickly and directly called in the final rendering or real-time runtime without having to perform real-time calculations again.

[0032] A preset baking viewpoint serves as the baseline viewpoint for rendering the target effect. Based on this preset baking viewpoint and the attribute parameters of each particle, the rendering position of the target effect on the blank image is determined and then drawn, resulting in a texture image. The pixel value of each pixel in the texture image includes the red, green, and blue pixel values.

[0033] Step 203: Determine the high-bit information image and the low-bit information image of the second image format based on the pixel values ​​of each pixel in the texture image.

[0034] In this embodiment, the second image format is RGBA32. Each pixel in the high-bit information image and the low-bit information image corresponds one-to-one with each pixel in the texture image.

[0035] It is understood that the high-bit information image, low-bit information image and texture image have the same pixel arrangement. For example, in a specific embodiment, the high-bit information image, low-bit information image and texture image are all 1920×1080 images, where 1920 is the number of pixels horizontally and 1080 is the number of pixels vertically.

[0036] For example, based on the known pixel values ​​of the pixels in the first row and first column of the texture image, the high-bit information corresponding to the pixels in the first row and first column of the high-bit information image and the low-bit information corresponding to the pixels in the first row and first column of the low-bit information image can be determined according to the pixel values ​​of the pixels in the first row and first column of the texture image.

[0037] The high-bit image is used to store the high-bit information of each pixel in the texture image. The low-bit image is used to store the low-bit information of each pixel in the texture image.

[0038] Based on the pixel values ​​of each pixel in the texture image, the high-bit information and low-bit information of each pixel value are determined respectively. The high-bit information image is determined based on the high-bit information of each pixel value, and the low-bit information image is determined based on the low-bit information of each pixel value.

[0039] Step 204: Render the target effect based on the high-resolution image and the low-resolution image.

[0040] The target effect is rendered based on the high-bit information corresponding to each pixel in the high-bit information image and the low-bit information corresponding to each pixel in the low-bit information image.

[0041] In the above special effects rendering method, the target special effect to be rendered is obtained, which includes multiple particles and the attribute parameters corresponding to each particle. Based on a preset baking perspective, the target special effect is drawn on a blank image in a first image format to obtain a texture image. Then, based on the pixel values ​​of each pixel in the texture image, a high-bit information image and a low-bit information image in a second image format are determined. Finally, the target special effect is rendered based on the high-bit information image and the low-bit information image.

[0042] It should be noted that the above-mentioned special effects rendering method applies to target special effects on a single plane. By pre-processing the target special effects, the corresponding high-bit information image and the low-bit information image are obtained. When it is necessary to render the target special effects, the target special effects can be rendered directly based on the high-bit information image and the low-bit information image, thereby solving the problem of high performance load when rendering special effects using related technologies.

[0043] It should be noted that the above special effects rendering method can directly avoid the performance consumption caused by layering and can completely restore the effect.

[0044] Based on a preset baking perspective, the target effect is drawn onto a blank image in the first image format, resulting in a texture image including:

[0045] Step 1: Determine the maximum bounding rectangle based on the position parameters of each particle in the target effect.

[0046] It should be noted that the maximum bounding rectangle is determined on the target effect, based on the position parameters of each particle in the target effect.

[0047] The maximum bounding rectangle is the maximum bounding rectangle that surrounds each particle in the target effect.

[0048] For example, the position parameters corresponding to each particle are traversed, the maximum and minimum values ​​of each particle on the vertical coordinate axis and the maximum and minimum values ​​of each particle on the horizontal coordinate axis are calculated, and then the maximum bounding rectangle is determined based on the maximum and minimum values ​​of each particle on the horizontal and vertical coordinate axes.

[0049] For example, the target effect includes four particles with coordinates (1, 2), (3, 2), (5, 1), and (1, 3). The maximum and minimum values ​​of each particle on the horizontal and vertical coordinate axes are calculated. For instance, the maximum value on the horizontal coordinate axis is 5, and the minimum value is 1. The maximum value on the vertical coordinate axis is 3, and the minimum value is 1. Therefore, the minimum bounding rectangle is the rectangle enclosed by lines X=1, X=5, Y=1, and Y=3.

[0050] Step 2: Determine the preset baking view based on the largest bounding rectangle.

[0051] The preset baking view is a top-view orthogonal view of the largest bounding rectangle, and can be determined based on the largest bounding rectangle. The preset baking view must include at least the largest bounding rectangle.

[0052] Step 3: Based on the preset baking perspective, the color parameters, position parameters, and material parameters of each particle, draw the target effect on a blank image in the first image format to obtain a texture image.

[0053] Based on a preset baking perspective, the position of each particle on the blank image of the first image format is determined according to the position parameters corresponding to each particle. The target effect is drawn according to the color parameters and material parameters corresponding to each particle, thereby obtaining a texture image.

[0054] For example, based on the position parameters of each particle, the corresponding pixel on the blank image is determined; based on the color parameters of each particle, the pixel value of the corresponding pixel is modified; and then based on the material parameters of each particle, the transparency of the corresponding pixel is modified, thereby obtaining a texture image. The pixel values ​​include red pixel values, green pixel values, and blue pixel values.

[0055] In other embodiments of this application, the target effect is drawn by modifying the pixel value of the pixel corresponding to each particle to the corresponding color parameter according to the color parameter, and modifying the opacity of the pixel corresponding to each particle according to the material parameter, thereby obtaining the texture image efficiently and conveniently.

[0056] In other embodiments of this application, the special effects rendering method further includes:

[0057] Step 1: Obtain the pixel value of each pixel in each row of the texture image. If a target row exists in the texture image, delete the target row in the texture image. The pixel value of each pixel in the target row is a preset pixel value.

[0058] The pixel values ​​included in the target behavior are all pixel rows with preset pixel values. The preset pixel values ​​are pre-set pixel values, that is, the default values ​​of each pixel in the blank image. For example, (0, 0, 0).

[0059] It should be noted that the pixel values ​​of each pixel in the blank image above are preset pixel values. In the process of drawing the target effect on the blank image of the first image format to obtain the texture image, the pixel values ​​of the pixels corresponding to each particle in the blank image will be modified.

[0060] Specifically, the process involves obtaining the pixel value of each pixel in each row of the texture image, sequentially determining whether the pixel value of each pixel in each row of the texture image is a preset pixel value, and if so, deleting the pixel row in which all pixels have the preset pixel value.

[0061] Step 2: Obtain the pixel value of each pixel in each column of the texture image. If a target column exists in the texture image, delete the target column from the texture image. The pixel value of each pixel in the target column is a preset pixel value.

[0062] The target column is a column of pixels whose pixel values ​​are all preset pixel values.

[0063] Specifically, the process involves obtaining the pixel value of each pixel in each column of the texture image, sequentially determining whether the pixel value of each column of pixels in the texture image is a preset pixel value, and deleting the pixel column in which all pixels have the preset pixel value.

[0064] In other embodiments of this application, determining the high-bit information image and the low-bit information image of the second image format based on the pixel values ​​of each pixel in the texture image includes:

[0065] Step 1: Determine the baseline value based on the pixel value of each pixel in the texture image.

[0066] The pixel values ​​include red, green, and blue pixel values. The baseline value is the maximum value of the red, green, and blue pixel values ​​of all pixels in the texture image.

[0067] For example, if a texture image includes three pixels with pixel values ​​of (255, 111, 100), (143, 122, 111), and (198, 200, 123), then the base value is 255.

[0068] Step 2: Generate a high-bit information image in a second image format based on the pixel values ​​of each pixel in the texture image.

[0069] Based on the red, green, and blue pixel values ​​of each pixel in the texture image, the corresponding red high-bit information, green high-bit information, and blue high-bit information of each pixel are calculated to generate a high-bit information image in the second image format.

[0070] The red, green, and blue pixel values ​​of each pixel in the texture image are compared with preset thresholds. If they are greater than the preset threshold, the red, green, or blue high-order information of the pixel is the preset threshold. If they are less than or equal to the preset threshold, the red, green, or blue high-order information of the pixel is the corresponding red, green, or blue pixel value.

[0071] After obtaining an initial high-resolution image in a preset second image format, the pixel values ​​of each pixel in the initial high-resolution image are modified to the corresponding red, green, and blue high-resolution information, thereby generating a high-resolution image. The pixel values ​​include red, green, and blue pixel values.

[0072] Step 3: Generate a low-bit information image in the second image format based on the pixel values ​​of each pixel in the texture image and the reference value.

[0073] Based on the red, green, and blue pixel values ​​and the baseline value of each pixel in the texture image, the red low-order information, green low-order information, and blue low-order information corresponding to each pixel are calculated respectively, thereby generating a low-order information image in the second image format.

[0074] The red, green, and blue pixel values ​​of each pixel in the texture image are compared with preset thresholds. If the value is greater than the preset threshold, the red, green, or blue low-order information of the pixel is equal to the corresponding color pixel value minus the preset threshold divided by the baseline value. If the value is less than or equal to the preset threshold, the red, green, or blue low-order information of the pixel is equal to zero.

[0075] After obtaining an initial low-bit information image in a preset second image format, the pixel values ​​of each pixel in the initial low-bit information image are modified to the corresponding red, green, and blue low-bit information, thereby generating a low-bit information image. The pixel values ​​include red, green, and blue pixel values.

[0076] It should be noted that, in this embodiment, based on the pixel values ​​of each pixel in the texture image, the high-bit information image and the low-bit information image of the second image format are determined, thereby storing the high-bit information and low-bit information of each pixel in the texture image, thus storing the color parameters of the texture image, laying the foundation for subsequent rendering of the target effect.

[0077] In other embodiments of this application, generating a high-bit information image in a second image format based on the pixel values ​​of each pixel in the texture image includes:

[0078] Step 1: Based on the pixel values ​​of each pixel in the texture image, determine the corresponding red, green, and blue pixel values ​​for each pixel.

[0079] For example, a pixel has a value of (198, 200, 123), with a red pixel value of 198, a green pixel value of 200, and a blue pixel value of 123.

[0080] Step 2: If the red pixel value of the first target pixel is greater than the preset threshold, then the red high-order information of the first target pixel is the preset threshold; if the red pixel value of the first target pixel is less than or equal to the preset threshold, then the red high-order information of the first target pixel is the red pixel value.

[0081] For example, if the red pixel value of a certain pixel is 198 and the preset threshold is 1, then the red high-order information of that pixel is 1.

[0082] For example, if the red pixel value of a certain pixel is 0.5 and the preset threshold is 1, then the red high-order information of that pixel is 0.5.

[0083] The preset threshold is a pre-set threshold for pixel values. For example, the preset threshold is 1.

[0084] The first target pixel is any one of the multiple pixels in the texture image.

[0085] Step 3: If the green pixel value of the first target pixel is greater than the preset threshold, then the green high-order information of the first target pixel is the preset threshold; if the green pixel value of the first target pixel is less than or equal to the preset threshold, then the green high-order information of the first target pixel is the green pixel value.

[0086] For example, if the green pixel value of a certain pixel is 200 and the preset threshold is 1, then the green high-order information of that pixel is 1.

[0087] For example, if the green pixel value of a certain pixel is 0.6 and the preset threshold is 1, then the green high-order information of that pixel is 0.6.

[0088] Step 4: If the blue pixel value of the first target pixel is greater than the preset threshold, then the blue high-order information of the first target pixel is the preset threshold; if the blue pixel value of the first target pixel is less than or equal to the preset threshold, then the blue high-order information of the first target pixel is the blue pixel value.

[0089] For example, if the blue pixel value of a certain pixel is 101 and the preset threshold is 1, then the blue high-order information of that pixel is 1.

[0090] For example, if the blue pixel value of a certain pixel is 0.3 and the preset threshold is 1, then the blue high-order information of that pixel is 0.3.

[0091] It should be noted that although the relevant steps are only performed on the first target pixel in this embodiment, in real-world scenarios, the relevant steps will be performed on each pixel in the texture image.

[0092] Step 5: Generate a high-bit information image in the second image format based on the red, green, and blue high-bit information corresponding to each pixel.

[0093] Based on the red, green, and blue high-bit information corresponding to each pixel, according to the preset second image format of the initial high-bit information image, each pixel in the initial high-bit information image is matched with the red, green, and blue high-bit information corresponding to each pixel in the texture image, thereby generating a high-bit information image.

[0094] The initial high-bit information image is a pre-set second image format information image, and its pixel arrangement is the same as that of the texture image.

[0095] It should be noted that in this embodiment, by comparing the red, green, and blue pixel values ​​of each pixel in the texture image with a preset threshold, if the values ​​are greater than the preset threshold, the red, green, or blue high-bit information of the pixel is the corresponding red, green, or blue pixel value, thereby generating a high-bit information image in the second image format, which improves the efficiency of generating high-bit information images.

[0096] In other embodiments of this application, generating a low-bit information image in a second image format based on the pixel values ​​of each pixel in the texture image and a reference value includes:

[0097] Step 1: Based on the pixel values ​​of each pixel in the texture image, determine the corresponding red, green, and blue pixel values ​​for each pixel.

[0098] Step 2: If the red pixel value of the first target pixel is greater than the preset threshold, subtract the preset threshold from the red pixel value of the first target pixel to obtain the first difference; divide the first difference by the reference value to obtain the red low-order information of the first target pixel; if the red pixel value of the first target pixel is less than or equal to the preset threshold, the red low-order information of the first target pixel is zero.

[0099] For example, the red pixel value of the first target pixel is 13, the preset threshold is 1, the base value is 24, the red pixel value of the first target pixel is greater than the preset threshold, so the first difference is 12, and the red low-order information of the first target pixel is 0.5.

[0100] For example, the red pixel value of the first target pixel is 0.5, the preset threshold is 1, the base value is 24, the red pixel value of the first target pixel is less than or equal to the preset threshold, so the red low-order information of the first target pixel is zero.

[0101] Step 3: If the green pixel value of the first target pixel is greater than the preset threshold, subtract the preset threshold from the green pixel value of the first target pixel to obtain the second difference; divide the second difference by the reference value to obtain the green low-order information of the first target pixel; if the green pixel value of the first target pixel is less than or equal to the preset threshold, the green low-order information of the first target pixel is zero.

[0102] For example, the green pixel value of the first target pixel is 7, the preset threshold is 1, the base value is 24, the green pixel value of the first target pixel is greater than the preset threshold, so the second difference is 6, and the green low-order information of the first target pixel is 0.25.

[0103] For example, the green pixel value of the first target pixel is 0.6, the preset threshold is 1, the base value is 24, the green pixel value of the first target pixel is less than or equal to the preset threshold, so the green low-order information of the first target pixel is zero.

[0104] Step 4: If the blue pixel value of the first target pixel is greater than the preset threshold, subtract the preset threshold from the blue pixel value of the first target pixel to obtain the third difference; divide the third difference by the reference value to obtain the blue low-order information of the first target pixel; if the blue pixel value of the first target pixel is less than or equal to the preset threshold, the blue low-order information of the first target pixel is zero.

[0105] For example, the blue pixel value of the first target pixel is 19, the preset threshold is 1, the base value is 24, the blue pixel value of the first target pixel is greater than the preset threshold, so the third value is 18, and the blue low-order information of the first target pixel is 0.75.

[0106] For example, the blue pixel value of the first target pixel is 0.3, the preset threshold is 1, the base value is 24, the blue pixel value of the first target pixel is less than or equal to the preset threshold, so the blue low-order information of the first target pixel is zero.

[0107] It should be noted that although the relevant steps are only performed on the first target pixel in this embodiment, in real-world scenarios, the relevant steps will be performed on each pixel in the texture image.

[0108] Step 5: Generate a low-bit information image in the second image format based on the red low-bit information, green low-bit information, and blue low-bit information corresponding to each pixel.

[0109] Based on the red, green, and blue low-bit information corresponding to each pixel, according to the preset second image format of the initial low-bit information image, each pixel in the initial low-bit information image is matched with the red, green, and blue low-bit information corresponding to each pixel in the texture image, thereby generating a low-bit information image.

[0110] The initial low-bit information image is a pre-set information image in a second image format, and its pixel arrangement is the same as that of the texture image.

[0111] In other embodiments of this application, rendering the target effect based on the high-bit information image and the low-bit information image includes:

[0112] Step 1: Obtain the red pixel value based on the red low-order information, reference value, and red high-order information of the second target pixel.

[0113] The red low-order information is multiplied by the reference value and added to the red high-order information to obtain the red pixel value.

[0114] For example, the red low-order information is zero, the base value is 24, the red high-order information is 0.5, zero is multiplied by the base value and added to 0.5 to get the red pixel value of 0.5.

[0115] For example, the red low-order information is 0.5, the base value is 24, the red high-order information is 1, 0.5 is multiplied by 24 and added to 1 to get the red pixel value of 13.

[0116] Step 2: Obtain the green pixel value based on the green low-order information, reference value, and green high-order information of the second target pixel.

[0117] The green low-order information is multiplied by the reference value and added to the green high-order information to obtain the green pixel value.

[0118] For example, the low-order green information is zero, the base value is 24, the high-order green information is 0.6, zero is multiplied by the base value and added to 0.6 to get the green pixel value of 0.6.

[0119] For example, the low-order green information is 0.25, the base value is 24, and the high-order green information is 1. 0.25 is multiplied by 24 and added to 1 to get a green pixel value of 7.

[0120] Step 3: Obtain the blue pixel value based on the blue low-order information, reference value, and blue high-order information of the second target pixel.

[0121] The blue low-order information is multiplied by the reference value and added to the blue high-order information to obtain the blue pixel value.

[0122] For example, the blue low-order information is zero, the base value is 24, the blue high-order information is 0.3, zero is multiplied by the base value and added to 0.3 to get the blue pixel value of 0.3.

[0123] For example, the blue low-order information is 0.75, the base value is 24, the blue high-order information is 1, 0.75 is multiplied by 24 and added to 1 to get the blue pixel value of 19.

[0124] It should be noted that although the relevant steps are only performed on the second target pixel in this embodiment, in real-world scenarios, the relevant steps will be performed on each pixel in the texture image.

[0125] Step 4: Based on the red, green, and blue pixel values ​​of each pixel, obtain the rendered target effect.

[0126] The pixel value of each pixel is determined based on the red, green, and blue pixel values ​​of each pixel, thus obtaining the target effect after rendering.
