[0032] The following detailed description of the technical solution of the present disclosure and how the technical solution of the present disclosure solves the above-mentioned technical problems is provided with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present disclosure will be described below in conjunction with the accompanying drawings.
[0033] The technical solution disclosed herein can be applied to applications involving the production, application, and use of dynamic fluid effects. The technical solution disclosed herein can be applied to terminal devices, which may include mobile terminals or computer devices. Mobile terminals may include, for example, smartphones, PDAs, tablet computers, wearable devices with displays, and the like; computer devices may include, for example, desktop computers, laptops, all-in-one computers, smart home devices, and the like.
[0034] The technical solution disclosed in the present invention can be implemented by a graphics processing unit (GPU) in a terminal device.
[0035] Figure 1 A flow chart of a dynamic fluid display method provided by an embodiment of the present disclosure is shown as follows: Figure 1 As shown, the method may include:
[0036] Step S101 : In response to an image input operation by a user, an image corresponding to the image input operation is displayed on a user display interface, and the fluid is superimposed on the image.
[0037] Among them, the user display interface can be a display interface in an application. The solution provided by the embodiment of the present disclosure can be implemented as an application or a functional plug-in of the application. When the terminal device detects the user's startup instruction for the application, the application is started and the user display interface is displayed; or, when the terminal device detects the user's trigger instruction for the functional plug-in of the application, the user display interface is displayed.
[0038] The terminal device can receive an image input by the user as a background image, and divide the background image into multiple grids, divided in the horizontal and vertical directions, where the horizontal direction corresponds to the width of the image and the vertical direction corresponds to the height of the image. Each grid corresponds to the position of each texture pixel of the GPU one-to-one. In a two-dimensional plane, the texture pixel corresponds to the position of the screen display pixel of the terminal device one-to-one. When the background image is displayed in the user display interface, each texture pixel corresponds to each pixel in the background image one-to-one, that is, each grid corresponds to each pixel in the background image one-to-one. Fluid is displayed in the background image, and texture pixels are used to save the parameters of the fluid corresponding to each grid, including initial velocity parameters, etc.
[0039] The background image can be any color, either single or multi-colored. The fluid can be any color, either static or in motion, and is displayed superimposed on the user-entered background image. Optionally, the fluid color and the background image can be different, resulting in a better display effect when the fluid and background image are displayed in the user interface.
[0040] In one example, the fluid is in a colorless, transparent, and static state, and the background image is an image composed of multiple colors showing a landscape. The fluid is superimposed on the background image, and a background image superimposed with a layer of transparent fluid is presented in the user display interface.
[0041] Step S102: When a target object is detected in the user display interface, attribute information of the target object is obtained.
[0042] The target object may be a specific object in the video, including but not limited to: the face, head, gesture, finger, etc. of a person or other creature.
[0043] Among them, gestures may include but are not limited to: pointing up, making a fist, making a heart shape, giving a thumbs up, etc.
[0044] The terminal device may activate a video capture device (e.g., a camera) of the terminal device to capture video. The duration of video capture may be a preset time period, or may be determined based on a video capture start instruction and a video capture end instruction, and this disclosure is not limited thereto. During the video capture process, the terminal device detects the target object in the user display interface, i.e., the video screen.
[0045] Optionally, the target object can also be a touch operation object. For example, the user touches the display screen of the terminal device with his finger and slides on the display screen. The terminal device detects the touch operation instruction, and the object that inputs the touch operation instruction is the touch operation object (in this case, the finger is the touch operation object, that is, the target object).
[0046] The target object's attribute information is information indicating specific attributes of the target object, and the specific attributes may include information related to the target object's speed and position.
[0047] Optionally, the position of the target object may be the position of at least one grid corresponding to the target object in the user display interface.
[0048] The specific implementation method of obtaining attribute information varies depending on the type of the target object.
[0049] In a possible implementation, the target object includes a target object in a video, the attribute information of the target object includes a speed change of the target object, and obtaining the attribute information of the target object includes:
[0050] Get the position of the target object in each frame of the video;
[0051] Determine the distance the target object moves from one frame to the next based on the position of the target object in each frame of the video;
[0052] Get the moving time of the target object from one frame image to the next frame image;
[0053] Determine the target object's moving speed at each moment based on the moving distance and moving time;
[0054] The speed change of the target object from the current moment to the next moment is determined based on the moving speed of the target object at each moment.
[0055] In practical applications, the target object can be a target object in a video, for example, a gesture in the video. After detecting a gesture in the video, the position of the gesture in each frame of the video is obtained. Based on the position of the gesture in each frame, the movement distance of the gesture in adjacent frames can be obtained. The movement time of the gesture in adjacent frames can be obtained. The movement speed of the gesture can be determined based on the movement distance and movement time. Based on the movement speed of the gesture at each moment, the speed change of the gesture can be determined.
[0056] In a possible implementation, the target object includes a touch operation object, the attribute information of the target object includes a speed change of the target object, and obtaining the attribute information of the target object includes:
[0057] Detecting the sliding operation speed of the touch operation object in the user display interface at each moment;
[0058] Based on the sliding operation speed, a speed change of the touch operation object from a current moment to a next moment is determined.
[0059] In actual applications, the target object can be a touch operation object, for example, a finger touches the screen and slides. The terminal device detects the corresponding position of the sliding operation at each moment, determines the moving distance from the current moment to the next moment based on the corresponding position at each moment, and determines the time interval from the current moment to the next moment. Based on the moving distance and time interval, the sliding operation speed at each moment can be calculated, and based on the sliding operation speed at each moment, the speed change of the finger sliding can be obtained.
[0060] Step S103 : determining changes in parameters of the fluid at each target texture pixel position related to the target object in the image according to the attribute information.
[0061] Based on changes in the target object's position, velocity, and other factors, changes in fluid parameters at target texel locations related to the target object can be determined in the image, thereby enabling interaction between the user and the terminal device. The target texels are texels related to the target object in the image, i.e., texels corresponding to the target object's range of action. There can be at least one target texel. The fluid parameters can be parameters related to the fluid's motion state, display state, and other factors.
[0062] Step S104 : displaying the dynamic fluid in the image according to the change of the parameters of the fluid at each target texture pixel position.
[0063] Specifically, according to the changes in relevant parameters such as the fluid's movement state and display state, the effect image after fluid simulation is displayed in the image, thereby showing that the fluid flow drives the background image to move together. When showing the dynamic effect of the fluid, it can be displayed in the form of video or dynamic graphics.
[0064] In a possible implementation, the fluid parameter includes a velocity parameter, and for each target texture pixel, the method further includes:
[0065] Get the time step for speed parameter update;
[0066] Get the velocity parameter of the fluid at the target texture pixel position at the current moment;
[0067] Determining a first texture pixel position at a current moment according to a time step, a velocity parameter of a fluid at a target texture pixel position at a current moment, and a position of the target texture pixel at a current moment;
[0068] The color at the first texture pixel position at the current moment is determined as the color of the fluid at the target texture pixel position at the next moment.
[0069] In practical applications, the time step for updating the velocity parameter can be preconfigured, and the velocity parameter of the fluid at each target texture pixel position is updated according to the time step. As the velocity parameter is updated, the color of the fluid at each target texture pixel position is also updated.
[0070] In one example, the color of the fluid at each target texture pixel position is updated by formula (1):
[0071]
[0072] Where x is the position of the grid corresponding to the target texture pixel; represents the color of the fluid at position x at time t+1; dt represents the time step; is the velocity parameter of the fluid at position x at time t; represents the first texture pixel position at time t; Represents the color of the fluid at the first texture pixel position at time t.
[0073] In a possible implementation, determining, based on the attribute information of the target object, a change in a parameter of a fluid at each target texture pixel position related to the target object in the image includes:
[0074] According to the velocity change of the target object, the change of the velocity parameter of the fluid at each target texture pixel position is determined.
[0075] In practical applications, the velocity parameters of the fluid at each target texture pixel position can be adjusted according to the velocity change of the target object, so that the fluid changes in velocity according to the velocity change of the target object. The velocity change of the fluid may include at least one of a change in velocity magnitude or a change in velocity direction.
[0076] In a possible implementation, the attribute information of the target object further includes initial position information of the target object and an effective radius of the target object. The change in velocity parameter of the fluid at each target texture pixel position is determined based on the velocity change of the target object, including:
[0077] For each target texture pixel, obtaining position information corresponding to the target texture pixel;
[0078] For each target texture pixel, the velocity parameter of the fluid at the target texture pixel position at the next moment is determined based on the velocity change of the target object, the initial position information of the target object, the effective radius of the target object, the position information corresponding to the target texture pixel, and the velocity parameter of the fluid at the target texture pixel position at the current moment.
[0079] In practical applications, the attribute information of the target object also includes the initial position information of the target object and the effective radius of the target object. The initial position information of the target object is the position of the target object when it first appears in the user display interface, and can be the position of at least one grid corresponding to the target object when it first appears in the user display interface. The effective radius of the target object represents the effective range of the target object in the user display interface. The effective radius can be pre-configured according to specific needs. The larger the effective radius, the larger the effective range of the target object in the user display interface. The position of the target object in the user display interface corresponds to the position of each target texture pixel. The position of each target texture pixel can be determined based on the position of the target object. The speed of the fluid at the target texture pixel position at the next moment is determined based on the speed change of the target object, the initial position information of the target object, the effective radius of the target object, the position information corresponding to the target texture pixel, and the speed of the fluid at the target texture pixel position at the current moment.
[0080] In one example, the velocity of the fluid at the target texture pixel position is updated according to formula (2):
[0081]
[0082] in, represents the velocity parameter of the fluid at the target texture pixel position x at time t+1, represents the velocity parameter of the fluid at the target texture pixel position x at time t, x represents the grid position corresponding to the target texture pixel, i.e., the target texture pixel position, p represents the initial position of the target object, r represents the effective radius, and Δv represents the velocity change of the target object from time t to time t+1.
[0083] In one possible implementation, if the target object is not detected in the user display interface, for each target texture pixel, the method further includes:
[0084] Determining a second texture pixel position at a current moment according to the time step, a velocity parameter of the fluid at the target texture pixel position at a current moment, and the position of the target texture pixel at a current moment;
[0085] The velocity parameter of the fluid at the second texture pixel position at the current moment is determined as the velocity parameter of the fluid at the target texture pixel position at the next moment.
[0086] In practical applications, if the initial state of the fluid is static, after the target object is detected, the parameters of the fluid at each target texture pixel position in the image change according to the attribute information of the target object, so that the fluid drives the image to start flowing. If at a certain moment, the user stops the interactive action, that is, the target object is no longer detected in the user display interface, then the fluid continues to flow according to inertia at this moment. The specific processing method is: for each target texture pixel in the image, according to the pre-configured speed update time step, the velocity parameter of the fluid at the target texture pixel position at the current moment, and the position of the target texture pixel at the current moment, determine the second texture pixel position at the current moment; determine the velocity parameter of the fluid at the second texture pixel position at the current moment as the velocity parameter of the fluid at the target texture pixel position at the next moment, and use the velocity parameter to update the color of the fluid. The color of the fluid can be updated according to the method shown in formula (1), so that the image flows with the inertia of the fluid.
[0087] In one example, the velocity of the fluid at each target texture pixel position is updated by formula (3):
[0088]
[0089] Where x is the position of the grid corresponding to the target texture pixel; represents the velocity parameter of the fluid at position x at time t+1; dt represents the time step; is the velocity parameter of the fluid at position x at time t; represents the second texture pixel position corresponding to the target texture pixel at position x at time t; Represents the velocity parameter of the fluid at the second texture pixel position at time t.
[0090] The dynamic fluid display method provided in the embodiment of the present disclosure can receive a background image input by the user, and display the fluid and the background image in an overlaid manner. When a target object is detected in the user display interface, the parameter changes of the fluid in the image are controlled according to the attribute information of the target object detected in the user display interface, and the dynamic fluid is displayed, thereby realizing that the fluid drives the background image to flow together. The interactive method is novel and interesting.
