Abstract
Description
Technical Field
[0001] This disclosure relates to the field of computer processing technology, and in particular to a method, apparatus, device, medium, and product for generating special effects images. Background Technology
[0002] In special effects production, fluid effects are often involved. Creating fluid effects requires the collaboration of multiple simulation systems.
[0003] Typically, multiple simulation systems are implemented by including a particle system, a simulation system for inter-particle fluid physics and mechanics, and a fluid material rendering system. The particle system creates multiple particles and sets their quantity and lifecycle. The inter-particle fluid physics and mechanics simulation system simulates the viscosity, density, and other properties of the particles; the fluid material rendering system achieves the fusion of particles.
[0004] When creating fluid effects using the above methods, users need to understand the multiple simulation systems mentioned above, which places high demands on them. Furthermore, the simulation system for interparticle fluid physics is only used to simulate the viscosity and density between particles, making it difficult to control the physical effects of particles from a visual perspective. This results in fluid effects that fail to meet the actual needs of users. Summary of the Invention
[0005] This disclosure provides a method, apparatus, device, medium, and product for generating special effects images, which aims to ensure that the special effects of the final generated target special effects image meet the actual needs of users while improving the convenience of users in creating fluid special effects.
[0006] In a first aspect, embodiments of this disclosure provide a method for generating special effects images, the method comprising:
[0007] In response to a triggering operation on the first control, an effects object generation interface is displayed to generate at least one effects object based on the triggering operation in the effects object generation interface;
[0008] Configure object motion parameters for the at least one special effects object to obtain at least one image of the at least one special effects object under the corresponding object motion parameters;
[0009] For the at least one image to be rendered, the image to be rendered is processed according to a preset rendering method to obtain the target special effects image of the image to be rendered.
[0010] Secondly, this disclosure also provides a special effects image generation apparatus, the apparatus comprising:
[0011] The special effects object generation module is used to display a special effects object generation interface in response to a trigger operation on the first control, so as to generate at least one special effects object based on the trigger operation in the special effects object generation interface;
[0012] The image to be rendered determination module is used to configure object motion parameters for the at least one special effects object to obtain at least one image to be rendered of the at least one special effects object under the corresponding object motion parameters;
[0013] The target special effects image determination module is used to render the at least one image to be rendered according to a preset rendering method to obtain the target special effects image of the image to be rendered.
[0014] Thirdly, embodiments of this disclosure also provide an electronic device, the electronic device comprising:
[0015] One or more processors;
[0016] Storage device for storing one or more programs.
[0017] When the one or more programs are executed by the one or more processors, the one or more processors implement the special effects image generation method as described in any of the embodiments of this disclosure.
[0018] Fourthly, embodiments of this disclosure also provide a storage medium containing computer-executable instructions, which, when executed by a computer processor, are used to perform the special effects image generation method as described in any of the embodiments of this disclosure.
[0019] Fifthly, embodiments of this disclosure also provide a computer program product, including a computer program that, when executed by a processor, implements the special effects image generation method as described in any of the embodiments of this disclosure.
[0020] The technical solution provided in this disclosure, in response to a trigger operation on a first control, displays a special effects object generation interface to generate at least one special effects object based on the trigger operation in the special effects object generation interface; configures object motion parameters for at least one special effects object to obtain at least one image to be rendered for at least one special effects object under the corresponding object motion parameters; for at least one image to be rendered, renders the image to be rendered according to a preset rendering method to obtain the target special effects image of the image to be rendered. This solves the problem in the prior art of creating fluid special effects through multiple simulation systems, which has high requirements for the user in creating fluid special effects and the fluid special effects produced are difficult to meet the user's needs. By providing the user with a visual special effects object generation interface, the user can determine the special effects object corresponding to the fluid special effects they want to generate as needed in the interface. After configuring the object motion parameters for each special effects object, each special effects object can be rendered on the image to be rendered according to the object motion parameters, so that the motion behavior of each special effects object in the special effects animation meets the user's motion requirements. Furthermore, by rendering the image to be rendered according to the preset rendering method, the target special effects image of the image to be rendered can be obtained, so that the special effects of the target special effects image meet the actual needs of users, and at the same time improve the convenience of users to create fluid special effects.

[0044] Before introducing this technical solution, an exemplary application scenario can be provided. This technical solution can be applied to any scenario that requires the creation of fluid effects. For example, in any scenario such as animation, video processing, or game development, when fluid effects need to be created, the technical solution provided in the embodiments of this disclosure can be adopted.
[0045] Figure 1 This is a flowchart illustrating a special effects image generation method provided in an embodiment of the present disclosure. The embodiments of the present disclosure are applicable to any fluid special effects production scenario. The method can be executed by a special effects image generation device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, such as a mobile terminal, a PC, or a server.
[0046] like Figure 1 As shown, the method in this embodiment may specifically include:
[0047] S110. In response to a trigger operation on the first control, display the special effects object generation interface to generate at least one special effects object based on the trigger operation in the special effects object generation interface.
[0048] The first control refers to the visual control used to access the special effects object generation interface. Triggering operations include, but are not limited to, at least one of clicking, touching, and swiping. The special effects object can be a particle object corresponding to the desired fluid effect. For example, if the fluid effect is water flow, the special effects object can be water droplets; if the fluid effect is a meteor shower, the special effects object can be stars; if the fluid effect is smoke, the special effects object can be particles; if the fluid effect is an explosion, the special effects object can be a fireball. In practical applications, the behavior of the fluid can be represented by simulating the movement of the special effects object, thus forming fluid effects.
[0049] Specifically, a first control can be developed in advance. For example, the first control can be an element in the user interface, displayed as a button, icon, or other form. When the first control is triggered, an effects object generation interface can be displayed. Then, fluid effects images can be created in the effects object generation interface. During the creation process, users can select or create at least one effects object in the effects object generation interface according to the style of fluid effects they want. Each effects object can be the same or different, generating corresponding fluid effects images based on the effects objects.
[0050] In this embodiment, the special effects object generation interface includes at least an instantiation sub-interface and a loop parameter setting sub-interface. Based on the trigger operation in the special effects object generation interface, at least one special effects object is generated, including: in response to the trigger operation of the second control in the instantiation sub-interface, displaying at least one prefab object to be selected, so as to trigger the selection of a special effects object from the at least one prefab object to be selected; in response to the trigger operation of the loop count editing control in the loop parameter setting sub-interface, generating at least one special effects object corresponding to the loop count.
[0051] The second control refers to the visual control used to display the prefab object to be selected. The loop count editing control refers to the visual control used to input the loop count. The loop count can be used to represent the number of effect objects in the effect image. The prefab object to be selected can be a pre-made base object. It should be noted that the prefab object to be selected can have a certain collision effect to prevent multiple generated effect objects from overlapping in space (visually they may be stacked together).
[0052] Specifically, a second control can be developed in advance within the instantiated sub-interface. When the second control is triggered, one or more pre-made prefab objects to be selected are displayed. When a prefab object to be selected is triggered, it can be used as an effect object. A loop count can be entered in the loop count edit control, and based on the user-input loop count and the triggered prefab objects, the same number of effect objects as the loop count will be generated.
[0053] For example, a user can click a button on the main interface (i.e., the first control), and the system will then display the effects object generation interface. This interface includes an instantiation sub-interface and a loop parameter setting sub-interface, such as... Figure 2 As shown. In the instantiation sub-interface, the user clicks on "Prefab Object" (i.e., the second control) to display the prefab objects to be selected, from which they can choose an effect object. A schematic diagram of the effect object can be seen as follows. Figure 3 As shown in the diagram. In the loop parameter settings sub-interface, enter the loop count in the "Loop Count" field (i.e., the loop count editing control). After completing the settings, at least one special effect object corresponding to the loop count will be generated. For example, if the user sets the loop count to 10, 10 special effect objects will be generated. See the diagram for an example. Figure 4 .
[0054] The advantage of this setting is that it allows users to dynamically select the special effects objects they want to create through visual editing, while also flexibly controlling the number of special effects objects in the fluid effects, thus meeting the user's needs for creating special effects and reducing the complexity of special effects production.
[0055] S120. Configure object motion parameters for at least one special effects object to obtain at least one image to be rendered for at least one special effects object under the corresponding object motion parameters.
[0056] Among them, the object motion parameters can be parameter information used to characterize the object's motion behavior. For example, the object motion parameters include, but are not limited to, velocity, acceleration, direction, curvature, rotation angle, displacement, motion path, and angular velocity.
[0057] In this embodiment, object motion parameters can be configured for at least one special effects object in batches; alternatively, object motion parameters can be configured for each special effects object individually; or, object motion parameters can be configured for each special effects object according to a preset motion step size. Furthermore, based on the object motion parameters of all or some of the special effects objects, these special effects objects can be rendered in an image to obtain a rendered image. This rendered image reflects the state of the special effects object at a specific moment under its corresponding object motion parameters. It should be noted that the position of the same special effects object may be different in different rendered images. Multiple consecutive rendered images constitute a fluid special effects animation of multiple special effects objects in motion, and the motion of the special effects objects is the visual representation of the fluid special effects.
[0058] In this embodiment, configuring motion parameters for at least one special effects object includes: for at least one special effects object, configuring an initial position and an initial orientation in the motion parameters. The initial position and initial orientation can be used to characterize the initial state of the special effects object within the fluid effect. The initial position can be represented by X and Y coordinates, and the initial orientation can be represented by a rotation angle or other orientation information.
[0059] The technical solution provided in this disclosure can accurately simulate the motion state and behavior of each special effects object in space by configuring an initial position and an initial direction for each special effects object.
[0060] To allow special effects objects to begin their lifecycle flow at a specified location and direction, their lifecycles can be configured to control their appearance and disappearance in the special effects video.
[0061] In this embodiment, the special effects object generation interface also includes an object display control sub-interface. This allows for the determination of the display time information for at least one special effects object in response to a triggering operation on a third control within the object display control sub-interface. The third control can be a visual control used to input or select the display time of the special effects object. For example, the third control can be a button, slider, drop-down menu, etc. The display time information includes the start display time and the end display time, which together define the entire lifecycle of the special effects object in the special effects video.
[0062] In practical applications, users can input the start and end times of the desired special effects object in the third control. The start time controls the initial display time of the special effects object in the fluid effects video, and the end time controls the end display time.
[0063] For example, see [link to previous article] Figure 2 Users can input the delay time (e.g., 5 seconds) for the special effects object in the "Delay" (i.e., the third control). The start display time is then 5 seconds, and the continuous display time can be from the 5th second to the last second of the video. The last second is the end display time, representing the duration of the special effects object's display from start to finish. This method allows for precise control of the entire lifecycle of the special effects object within the video, ensuring that the object is displayed according to the specified time during rendering or playback, thus enhancing the visual impact of fluid special effects.
[0064] S130. For at least one image to be rendered, render the image according to the preset rendering method to obtain the target effect image of the image to be rendered.
[0065] Among them, the preset rendering method can refer to the method used to control how the image is rendered.
[0066] In this embodiment, at least one rendering method can be pre-configured. Optionally, the preset rendering method may include, but is not limited to, scaling, color processing, shadow processing, brightness processing, texture processing, dilation processing, blurring, and other rendering methods. After determining the image to be rendered, each image can be rendered using the preset rendering method to obtain the target effect image corresponding to each image. Continuous target effect images form an animated video of fluid effects. For example, if the preset rendering method is brightness processing, then a certain brightness or illumination can be added to some pixels in each effect object in the image to be rendered to achieve a sparkling fluid effect. It should be noted that the preset rendering method can be dynamically updated according to different rendering requirements and effects to achieve the creation of various specific visual effects of fluid effects.
[0067] The technical solution provided in this disclosure, in response to a trigger operation on a first control, displays a special effects object generation interface to generate at least one special effects object based on the trigger operation in the special effects object generation interface; configures object motion parameters for at least one special effects object to obtain at least one image to be rendered for at least one special effects object under the corresponding object motion parameters; for at least one image to be rendered, renders the image to be rendered according to a preset rendering method to obtain the target special effects image of the image to be rendered. This solves the problem in the prior art of creating fluid special effects through multiple simulation systems, which has high requirements for the user in creating fluid special effects and the fluid special effects produced are difficult to meet the user's needs. By providing the user with a visual special effects object generation interface, the user can determine the special effects object corresponding to the fluid special effects they want to generate as needed in the interface. After configuring the object motion parameters for each special effects object, each special effects object can be rendered on the image to be rendered according to the object motion parameters, so that the motion behavior of each special effects object in the special effects animation meets the user's motion requirements. Furthermore, by rendering the image to be rendered according to the preset rendering method, the target special effects image of the image to be rendered can be obtained, so that the special effects of the target special effects image meet the actual needs of users, and at the same time improve the convenience of users to create fluid special effects.
[0068] Figure 5 This is a flowchart illustrating a special effects image generation method provided in an embodiment of this disclosure. Based on the above embodiments, the technical solution of this embodiment further includes configuring a basic texture for the created scene object, generating a prefab object to be processed, and then adding collider parameters and rigid body component parameters to the prefab object to be processed to obtain a prefab object to be selected. A special effects object is then selected from the prefab objects to be selected based on a trigger operation in the special effects object generation interface. For detailed implementation, please refer to the detailed description of the embodiments of this disclosure. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.
[0069] like Figure 5 As shown, the method in this embodiment may specifically include:
[0070] S210. After configuring the basic texture for the created scene object, generate the prefab object to be processed.
[0071] In this context, a scene object can refer to a base object corresponding to the various fluid effects to be generated. For example, to create a water flow effect, the scene object can be a circle; to create a meteor shower effect, it can be a pentagram; and to create a smoke effect, it can be a dot. Of course, the same scene object can be applied to various types of fluid effects. For instance, a circle can be used to represent quicksand, raindrops, water splashes, and other fluid effects. The base texture can be various styles of texture maps. For example, a base texture includes, but is not limited to, information such as color, transparency, and lighting.
[0072] Specifically, multiple scene objects can be pre-created. Then, a base texture can be selected for each scene object, and the base texture can be mapped onto the surface of the scene object. The scene object configured with the base texture can be used as a prefab object to be processed. For example, a circular 2D scene object can be created, and a circular base texture can be applied to it to obtain the prefab object to be processed.
[0073] S220. Add collision body parameters and rigid body component parameters to the prefab object to be processed to obtain the prefab object to be selected, so as to select the effect object from the prefab object based on the trigger operation in the effect object generation interface.
[0074] Collider parameters refer to parameters that define how an object interacts with other objects through collisions. These parameters include, but are not limited to, collider type (e.g., sphere, box, capsule, mesh), collider offset relative to the object, dimensions (e.g., radius, height, width), collision level (colliders can be set on different physical layers to control which collisions should be detected), self-level, physical material (i.e., the physical properties of the object when colliding with a collider, such as friction and elasticity), and touchability. Rigid body component parameters refer to properties that define how an object responds to forces, torques, and collisions. These parameters include, but are not limited to, mass, whether gravity is used, damping, angular drag (the resistance experienced when the object rotates), external forces, torque, velocity, angular velocity, and whether it is static.
[0075] Specifically, collision body parameters and rigid body component parameters can be configured for the prefab object to be processed, and the configured collision body parameters and rigid body component parameters can be applied to the prefab object to be processed to obtain the prefab object to be selected, so as to simulate the collision effect between different prefab objects to be selected through these parameters.
[0076] For example, the size of the prefab object to be processed can also be adjusted. Simultaneously, rigid body component parameters can be added to the prefab object in the rigid body component parameter configuration page, such as mass, gravity, angular drag, external forces (including external forces in the X and Y axes), torque, velocity (including velocity in the X and Y axes), angular velocity, and whether it is static. A schematic diagram of the rigid body component parameter configuration page can be found here. Figure 6 You can add collider parameters to the prefab object to be processed in the collider parameter configuration page, such as offset (including offset in the X-axis direction and offset in the Y-axis direction), radius (e.g., 5), collision level, physical material, and touchability. A diagram of the collider parameter configuration page can be found here. Figure 7 .
[0077] To further enhance the collision effects between objects, friction and elasticity parameters can be configured for the prefab objects to be processed. These parameters control the motion information when objects collide. Friction parameters reflect the friction effect between object surfaces. For example, friction parameters can include dynamic friction and static friction. Dynamic friction refers to the frictional force used when an object is moving. Static friction is the frictional force used when an object is stationary. Elasticity parameters reflect the degree of rebound during a collision; their values can be between 0 and 1. For example, a value of 0 indicates no elasticity, and a value of 1 indicates a fully elastic collision.
[0078] Specifically, friction and elasticity parameters can be configured for the prefab objects to be processed according to the special effects requirements, and these parameters can be applied to the prefab objects to achieve the desired collision effect. For example, friction and elasticity parameters can be set using physical materials, which define specific friction and elasticity values. Thus, by adding a physical material to the prefab object to be processed, its friction and elasticity parameters can be adjusted. This allows the selection of prefab objects to be determined, simulating the friction effect between different prefab objects using these parameters. The friction effect influences the behavior of the special effects objects when they come into contact and collide, further improving the realism of the collision effect. The advantage of this setup is that by configuring basic collision and bounce effects for the selected prefab objects during the pre-production stage, the creation of subsequent fluid adhesion, density, and other effects can be effectively simplified, significantly reducing the complexity of creating fluid special effects.
[0079] It should be noted that after selecting an effect object from the prefab objects to be selected, at least one of the friction parameters, elastic parameters, collision parameters, and rigid body component parameters of the effect object can be changed according to the needs of the effect production, so as to update the parameters of the effect object based on the updated parameters.
[0080] The technical solution provided in this disclosure, by determining the prefab object to be selected, allows for the selection of special effect objects from the prefab object, ensuring that the special effect objects have the same collision effect and preventing overlapping of special effect objects when generating multiple special effect objects. Furthermore, the same prefab object can be used multiple times in creating various types of fluid effects without needing to be reconfigured each time, improving the convenience of fluid effect creation.
[0081] Figure 8 This is a flowchart illustrating a special effects image generation method provided in an embodiment of this disclosure. Based on the above embodiments, the technical solution of this embodiment includes the following preset rendering method: downsampling the image to be rendered to obtain a blurred image; performing at least one blurring process on the blurred image to obtain an image to be used; and determining the target special effects image of the image to be rendered based on the transparency value of at least one pixel in the image to be used and a preset transparency threshold. Specific implementation details can be found in the detailed description of the embodiments of this disclosure. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here.
[0082] like Figure 8 As shown, the method in this embodiment may specifically include:
[0083] S310. Downsample the image to be rendered to obtain the image to be blurred.
[0084] In this embodiment, a downsampling algorithm can be used to downsample the image to be rendered, reducing its resolution. The downsampled image is then used as the image to be blurred. By downsampling, the edges of various special effects objects in the image can be effectively blurred, making the edges smoother and thus improving the realism of the fluid effects.
[0085] For example, assuming the resolution of the image to be rendered is 720*1280, downsampling it once can reduce its resolution from 720*1280 to 180*320, that is, the resolution of the image to be blurred is 180*320.
[0086] S320. Perform at least one blurring process on the image to be blurred to obtain the image to be used.
[0087] In this embodiment, a blurring algorithm can be used to perform one or more blurring processes on the image to be blurred. The advantage of a single blurring process is that it can expand the area of edge expansion of each special effect object in the image. The advantage of multiple blurring processes is that it can more effectively expand the area of expansion of each special effect object in the image, making the special effect objects appear to be "adhered" together. Optionally, the blurring algorithm can be a Gaussian blur algorithm, which replaces each pixel in the image to be blurred with the weighted average of its surrounding pixels, with pixels closer to the center having a higher weight, thereby achieving a blurring effect. Alternatively, the blurring algorithm can also be a median filtering algorithm, which replaces each pixel in the image to be blurred with the median value of its surrounding pixels. Alternatively, the blurring algorithm can also be a mean filtering algorithm, which replaces each pixel in the image to be blurred with the average value of its surrounding pixels. Alternatively, the blurring algorithm can also be a box blur, radial blur, scaling blur, or other similar algorithms.
[0088] In this embodiment, performing at least one blurring process on the image to be blurred to obtain an image to be used includes: for at least one pixel in the image to be blurred, updating the current pixel value based on the current pixel value of the pixel and the pixel values of other pixels in the preset neighborhood of the pixel; obtaining an image to be blurred again based on the updated pixel value of at least one pixel in the image to be blurred, and using the image to be blurred again as the image to be blurred; and using the image to be blurred obtained when the number of blurring processes reaches a preset threshold as the image to be used.
[0089] The preset threshold can be a limit to restrict the number of blurring operations; for example, the preset threshold can be 3 or 5. The preset neighborhood can be used to characterize the area surrounding a pixel. For example, the preset neighborhood can be a rectangle (the side length can be customized), such as a 3x3 rectangle; or, the preset neighborhood can be a circle (the radius of which can be customized), such as a circle with a radius of m.
[0090] In this embodiment, for each pixel in the image to be blurred, a preset neighborhood corresponding to the current pixel can be determined with the current pixel as the center, and pixels located within the preset neighborhood can be regarded as other pixels. For example, see Figure 9Assuming a preset neighborhood of 3x3, if pixel 6 is the current pixel, then pixels 1, 2, 3, 5, 7, 9, 10, and 11 within the 3x3 neighborhood can be considered as other pixels. Further, the mean between the current pixel value and the pixel values of its corresponding other pixels can be calculated, and this mean can be used as the new pixel value for the current pixel; alternatively, the mean between the pixel values of the corresponding other pixels can be calculated, and this mean can be used as the new pixel value for the current pixel. That is, the current pixel value is updated, and correspondingly, the pixel value of every pixel in the image to be blurred is updated in this way, indicating that the image to be blurred has been updated. At this point, the updated image to be blurred can be used as the image to be blurred again. Further, the image to be blurred again can be used as the image to be blurred again, and blurring processing can be performed on the image to be blurred at least once more, updating the current pixel value of at least one pixel in the image to be blurred. By performing multiple blurring processes in this manner and comparing the number of blurring processes with a preset threshold, when the number of blurring processes reaches the preset threshold, it can be considered that the preset number of blurring processes has been performed, and the image to be blurred obtained after the last blurring process can be determined as the image to be used.
[0091] For example, for each pixel in the effect object in the image to be blurred, the color of that pixel can be updated based on the average color of the pixel (i.e., pixel value) and the colors of other pixels within its upper, lower, left, and right transparency regions (i.e., preset neighborhoods). The blurring process can be performed 5 times (i.e., a preset number of times threshold), using the same or a different preset neighborhood size each time.
[0092] The technical solution provided in this embodiment expands the size of the special effect object by using the current pixel value and the pixel values of other pixels in the preset neighborhood of the pixel to fill the current pixel value during each blurring process. At the same time, it also radially blurs the color of the special effect object and improves the adhesion effect between special effect objects.
[0093] S330. Based on the transparency value of at least one pixel in the image to be used and a preset transparency threshold, determine the target effect image of the image to be rendered.
[0094] It should be noted that after blurring, the edges of the special effects objects in the resulting image may become blurred, and the color of the edges of the special effects objects may mix with the color of the surrounding pixels, resulting in unclear boundaries between the special effects objects and affecting the visual effect.
[0095] To address this issue, the transparency value of at least one pixel in the image to be used can be compared with a preset transparency threshold. If the pixel's transparency value is greater than the preset threshold, its color value is rendered as the color value of the effect object. If the pixel's transparency value is less than or equal to the preset threshold, its transparency value is rendered as the preset transparency value. For example, the preset transparency value can be 0; when the pixel's transparency value is rendered as 0, it means that the pixel's color is transparent. Similarly, the preset transparency threshold can be 0.6; when the pixel's transparency value is greater than 0.6, its color is rendered as the color of the effect object; otherwise, it is transparent. The advantage of this setting is that it achieves a certain degree of edge sharpness between effect objects while also maintaining a good adhesion effect between them, thereby enhancing the visual effect of the fluid effect.
[0096] To further improve the edge effect between special effects objects, for the pixels to be processed in the target special effects image, when the transparency value of the pixel to be processed is within a preset transparency range, the pixel value of the pixel to be processed is adjusted to the first pixel value; when the transparency value of the pixel to be processed is not within the preset transparency range, the pixel value of the pixel to be processed is adjusted to the second pixel value; wherein, the first pixel value is the pixel value of the background to which the special effects object belongs, and the second pixel value is the pixel value assigned to the special effects object.
[0097] Specifically, when the transparency value of the pixel to be processed is within the preset transparency range, the pixel value can be adjusted to the first pixel value. When the transparency value of the pixel to be processed exceeds the maximum value in the preset transparency range, the pixel value can be adjusted to the second pixel value; or, when the transparency value of the pixel to be processed is less than the minimum value in the preset transparency range, the pixel value can be adjusted to the second pixel value. The advantage of this setting is that by considering the pixel values of the effect object itself and the pixel values of the background to which the effect object belongs, the pixel values of the pixels are updated, which can effectively blur the gaps between effect objects, making them stick together, thereby enhancing the edge effect of the effect object.
[0098] For example, the preset transparency range can be (0.1, 0, 3). When the transparency value of the pixel to be processed is greater than 0.1 and less than 0.3, the pixel value of the pixel to be processed is adjusted to the pixel value of the background to which the effect object belongs. When the transparency value of the pixel to be processed is greater than 0.3, the pixel value of the pixel to be processed is adjusted to the pixel value assigned to the effect object.
[0099] The technical solution provided in this disclosure, by downsampling the image to be rendered to obtain a blurred image, effectively blurs the edges of various special effects objects in the image, making the edges smoother and thus improving the realism of the fluid effects. Furthermore, by performing at least one blurring process on the blurred image to obtain the image to be used, the expansion area of the special effects objects in the image can be increased, creating a sticky effect between the special effects objects. Finally, by adjusting the color of the pixels in the image based on the transparency value of at least one pixel in the image to be used and a preset transparency threshold, the edges of the special effects objects in the target special effects image can maintain a certain degree of clarity while also exhibiting a good sticky effect between the special effects objects, thereby enhancing the visual effect of the fluid effects.
