[0044] Figure 2 Schematically shows a block diagram of a configuration of the control device 100 according to an exemplary embodiment. Figure 2 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive input operation instructions from the user, and convert the operation instructions into instructions that the display device 200 can recognize and respond to, playing the role of an interactive intermediary between the user and the display device 200.

[0045] like Figure 3The display device 200 includes at least one of a tuner and demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface.

For example, the detector 230 includes a light receiver, a sensor for collecting the intensity of ambient light; or, the detector 230 includes an image collector, such as a camera, which can be used to collect external environment scenes, user attributes or user interaction gestures; or, the detector 230 includes a sound collector, such as a microphone, etc., for receiving external sounds.

[0053] The tuner-demodulator 210 receives broadcast television signals via wired or wireless reception, and demodulates audio and video signals, such as EPG data signals, from a plurality of wireless or wired broadcast television signals.

[0054] In some embodiments, the controller 250 and the tuner-demodulator 210 may be located in different separate devices, that is, the tuner-demodulator 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0055] The controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command for selecting a UI object to be displayed on the display 260, the controller 250 can perform operations related to the object selected by the user command.

[0056] In some embodiments, the controller includes a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), RAM Random Access Memory (RAM), ROM (Read-Only Memory, ROM), a first interface to an nth interface for input / output, a communication bus (Bus), etc.

Alternatively, the user may input a user command through a specific sound or gesture, and the user input interface recognizes the sound or gesture through a sensor to receive the user input command.

[0058] "User interface" is the medium interface for interaction and information exchange between applications or operating systems and users. It realizes the conversion between the internal form of information and the form acceptable to users. The commonly used form of user interface is the Graphical User Interface (GUI), which refers to the user interface related to computer operation displayed in a graphical way. It can be an interface element such as an icon, window, control, etc. displayed on the display screen of an electronic device, where the control can include icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc.

[0059] like Figure 4In some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications) layer (referred to as "application layer"), the application framework layer (Application Framework) layer (referred to as "framework layer"), the Android runtime (Android runtime) and system library layer (referred to as "system runtime library layer"), and the kernel layer.

[0060] In some embodiments, at least one application is running in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. provided by the operating system, or applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the above examples.

[0061] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions that applications in the application layer take. Through the API interface, applications can access system resources and obtain system services during execution.

The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, capturing the screen, and controlling the display window changes (for example, reducing the display window, shaking the display, distorting the display, etc.).

[0064] In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C / C++ library contained in the system runtime layer to implement the functions to be implemented by the framework layer.

[0065] In some embodiments, the kernel layer is a layer between hardware and software. Figure 4 As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0066] The following is a description of the related technologies of the embodiments of the present application.

[0067] In the traditional animation production process, the swaying effect of plants is generally achieved through sequence frames. Designers need to create a series of static images (i.e., sequence frames) for each plant, and create the illusion of motion by displaying a series of static images in rapid succession. Each static image is called a "frame". When these frames are displayed in sequence at a fast enough speed, the user's eyes will see smooth movement due to the visual persistence effect, and can also feel the swaying of the plants. However, since the sequence frames are pre-designed, the form of the simulated swaying effect of plants is relatively fixed and cannot be dynamically adjusted according to real-time input parameters (such as wind speed, etc.). For example, when the wind speed increases in real time, the swaying degree of the plant becomes larger, and when the wind speed decreases in real time, the swaying degree of the plant becomes smaller. The swaying effect of plants simulated by sequence frames is relatively monotonous and not realistic, and has poor interactivity and artistry. Since the transition between each sequence frame is manually set by the designer, it is difficult to accurately capture the subtle changes of plants swaying in the wind in nature. The result is often that the animation effect appears mechanical and unnatural, and cannot truly reproduce the dynamic behavior of plants under different environmental conditions. In order to cover as many possible scenarios as possible, designers must prepare a large number of sequence frames for each situation, which not only increases the workload but also takes up a lot of storage space. In addition, when the animation needs to be modified or optimized, it is often necessary to remake the entire sequence, which is inefficient.

[0068] In view of this, the embodiments of the present application provide a display device, method, system and storage medium. After obtaining the wind speed, the wind speed and the preset index sequence are calculated to determine the coordinate sequence corresponding to the virtual plant. The coordinate sequence includes the coordinates of the virtual plant corresponding to each index in the preset index sequence. The connecting line of the coordinate sequence is a curve of the virtual plant swinging with the wind speed. The coordinate sequence is traversed, and the predicted coordinates corresponding to each coordinate in the coordinate sequence and the preset grid parameters are determined. According to the predicted coordinates corresponding to each coordinate in the coordinate sequence, the animation effect of the virtual plant swinging in the wind is simulated through the display. In this way, after obtaining the wind speed, the coordinate sequence is determined according to the wind speed, and according to the predicted coordinates corresponding to each coordinate in the coordinate sequence, the predicted coordinates corresponding to each coordinate in the coordinate sequence are drawn, so as to display the posture of the virtual plant corresponding to the wind speed. Furthermore, according to different wind speeds, the coordinate sequence obtained by the virtual plant and the predicted coordinates corresponding to each coordinate in the coordinate sequence are also different. In the animation effect, different degrees of plant bending can be displayed. The whole picture changes with the change of wind speed. The picture is vivid, artistic and innovative.

[0069] In order to facilitate further understanding of the technical solutions in some embodiments of the present application, the technical solutions of the display device and the display method, as well as how the technical solutions solve the above-mentioned technical problems are described in detail below in combination with some specific embodiments and drawings. The various embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of them.

[0070] It should be understood that in some embodiments, the display method provided in the present application can be used to display virtual plants, or objects that swing under the action of wind, such as wind chimes, ropes, flags, wires, etc., or hair, clothes, curtains, etc., which can all be displayed using the display method provided in the embodiments of the present application, and the embodiments of the present application are not limited here.

[0071] like Figure 5 As shown, Figure 5 The schematic flow chart of the display method provided in the embodiment of the present application is applied to a display device, the display device includes a display and a controller. Specifically, the embodiment of the present application takes the target element as a virtual plant as an example, and the controller is configured to perform the following steps:

[0072] S501, calculating the acquired wind speed and the preset index sequence to determine the reference coordinate sequence corresponding to the virtual plant.

[0073] The reference coordinate sequence includes coordinates of the virtual plant corresponding to each index in the preset index sequence, and the connecting line of the reference coordinate sequence is a curve of the virtual plant swaying with wind speed.

[0074] In one implementation, the acquired wind speed and the preset index sequence may be input into a preset curve model to determine a reference coordinate sequence corresponding to the virtual plant.

[0075] Each coordinate in the reference coordinate sequence corresponding to the virtual plant can represent the position of the virtual plant in the grid. By connecting each coordinate in the reference coordinate sequence corresponding to the virtual plant, a simulation curve of the virtual plant in the grid can be obtained. It can be understood that the reference coordinate sequence corresponding to the virtual plant can be a set of central contour points of a plant. For example, if the virtual plant is divided into 50 segments in the vertical direction, the central contour point set can be a set of central point coordinates of each of the 50 segments. For example, Figure 6 As shown, Figure 6 A schematic diagram of virtual plant segmentation in an embodiment of the present application is shown in FIG.

[0076] The preset curve model is a model used to simulate the bending state of plants when swaying in the wind, and may be a parabola model.

[0077] For example, the preset curve model is y 2 =mx, when the coefficient m is different, the curve of the virtual plant swinging with the wind speed obtained according to the preset curve model is also different. The larger the value of m, the smoother and more vertical the curve of the virtual plant swinging with the wind speed. At this time, the amplitude of the virtual plant swinging with the wind is smaller, which corresponds to the virtual plant swinging at a relatively low wind speed; the smaller the value of m, the greater the curvature of the curve of the virtual plant swinging with the wind speed. At this time, the amplitude of the virtual plant swinging with the wind deviates more from the static position of the plant, which corresponds to the virtual plant swinging at a relatively high wind speed. For example, Figure 7 As shown, Figure 7 Graphs of the parabolic model with different coefficients are shown in FIG.

[0078] It should be noted that in the actual simulation process, the plant curve simulation basically shows a linear growth in the vertical direction and a quadratic function relationship in the horizontal direction.

[0079] In a possible implementation, each coordinate in the coordinate sequence corresponding to the virtual plant includes a horizontal coordinate and a vertical coordinate. The horizontal coordinate of the virtual plant corresponding to each index in the preset index sequence can be determined according to the acquired wind speed, the preset index sequence and the coordinate formula of the virtual plant in the horizontal direction; the vertical coordinate of the virtual plant corresponding to each index in the preset index sequence can be determined according to the preset index sequence and the coordinate formula of the virtual plant in the vertical direction.

[0080] Among them, the coordinate formula of the virtual plant in the horizontal direction satisfies:

[0081]

[0082] The coordinate formula of the virtual plant in the vertical direction satisfies:

[0083]

[0084] In formula (1), x represents the horizontal coordinate of any coordinate in the coordinate sequence corresponding to the virtual plant, a represents the first preset parameter, b represents the second preset parameter, wind represents the wind speed, and index represents any index value in the preset index sequence; a*wind represents the value of the wind speed after a linear change.

[0085] In formula (2), y represents the vertical coordinate of any coordinate in the coordinate sequence corresponding to the virtual plant.

[0086] As an example but not a limitation, in the above formula (1) and formula (2), a is taken as 0.05 and b is taken as 50.

[0087] It should be noted that if the value of a is small, the virtual plant sways in the horizontal direction with the wind: almost no swaying, and the virtual plant is basically vertical. If the value of a is large, the virtual plant sways in the horizontal direction with the wind: too much swing, and even tends to fall to the ground. When the value of a is 0.05, the swaying amplitude of the plant is moderate.

[0088] In a possible implementation, the above formula (1) and formula (2) are transformed using an intermediate parameter t, and

[0089]

[0090] The above formula (1) is transformed into the following formula (3):

[0091] x=a*wind*t 2 (3)

[0092] Convert the above formula (2) into formula (4):

[0093] y=t (4)

[0094] In this implementation, starting from the first index in the preset index sequence as the current index, the value of the intermediate parameter t is determined according to the current index and the preset second parameter b, and then the horizontal coordinate and vertical coordinate of the virtual plant corresponding to the current index are determined according to formula (3) and formula (4), and the coordinates (x, y) of the virtual plant corresponding to the current index are added to the coordinate sequence corresponding to the virtual plant, and it is determined whether the current index is the last index in the preset index sequence. If the current index is not the last index in the preset index sequence, it is switched to the next index and the calculation is performed again until the current index is determined to be the last index in the preset index sequence, and the coordinate sequence corresponding to the virtual plant is saved. In this way, the coordinate sequence corresponding to the virtual plant includes the coordinates of the virtual plant corresponding to each index in the preset index sequence.

[0095] In an embodiment of the present application, the preset index sequence is determined based on the preset number of segments of the virtual plant in the vertical direction (longitudinal direction). For example, if the virtual plant is divided into 50 segments in the longitudinal direction, the preset index sequence takes 50 integers from 0 to 49, or 50 integers from 1 to 50. Obviously, the number of indexes in the preset index sequence is the same as the number of segments into which the virtual plant is divided in the longitudinal direction.

[0096] It can be understood that, for each index in the preset index sequence, the coordinates of the virtual plant corresponding to each index can be determined according to formula (1) and formula (2).

[0097] In some embodiments, the controller may obtain wind speed through a sensor such as a wind sensor, or the controller may be connected to a local or remote weather station through a network to obtain real-time wind speed data. The embodiments of the present application do not limit the manner in which the controller obtains wind speed.

[0098] In some embodiments, before S501, the display method may further include:

[0099] S500, obtain wind speed.

[0100] Among them, wind speed refers to the speed of air movement relative to the earth's surface, which can be obtained from nature in real time.

[0101] For example, the wind speed is obtained through a weather application (Application, APP), and the wind speed can be expressed by a wind force level (Beaufort wind force level). Specifically, the Beaufort wind force level is a system that divides wind force into 13 levels according to wind speed, and each level corresponds to a different wind speed range and natural phenomenon. For example, the real-time wind force level is obtained through a weather APP, for example: level 5 wind force, level 6 wind force, etc.

[0102] It can be understood that by obtaining wind speed in real time through the weather APP and applying it to the swaying of virtual plants in the wind in the embodiment of the present application, the swaying of virtual plants in the wind in the embodiment of the present application can simulate the swaying of plants in the actual weather environment and display the animation effect of plants swaying in nature in real time.

[0103] S502, traversing the reference coordinate sequence corresponding to the virtual plant, and determining the predicted coordinate corresponding to each reference coordinate in the reference coordinate sequence according to each reference coordinate in the reference coordinate sequence and a preset grid parameter.

[0104] The preset grid parameter may be the width or height of a grid unit, or may be a parameter determined according to the width or height of a grid. For example, the preset grid parameter may be half of the grid width.

[0105] In an embodiment of the present application, a reference coordinate sequence corresponding to the virtual plant is traversed, the position of each reference coordinate in the reference coordinate sequence is judged, and for different coordinate positions, the first vector corresponding to the reference coordinate is determined, and then the predicted coordinate corresponding to the reference coordinate is determined based on the reference coordinate, the preset grid parameters and the first vector corresponding to the reference coordinate.

[0106] Specifically, the coordinate sequence of the virtual plant includes the first reference coordinate, and S502 specifically includes S5021 and S5022, wherein:

[0107] S5021: Determine a first vector according to the first reference coordinates.

[0108] Depending on whether the first reference coordinate is the first coordinate in the coordinate sequence corresponding to the virtual plant, or the first reference coordinate is any coordinate other than the first coordinate in the reference coordinate sequence corresponding to the virtual plant, the method of determining the first vector is different. The following describes the two methods of determining the first vector:

[0109] Method 1: When the first reference coordinate is the first coordinate in the reference coordinate sequence corresponding to the virtual plant, the normal vector of the preset direction vector corresponding to the first reference coordinate is determined as the first vector.

[0110] Exemplarily, the first coordinate in the reference coordinate sequence corresponding to the virtual plant is the root coordinate of the virtual plant. It can be understood that the virtual plant usually grows longitudinally along the Y-axis of the XY coordinate system, and the root of the virtual plant is usually perpendicular to the ground. The first vector corresponding to the root coordinate is set to (1, 0). In this way, the first vector corresponding to the root coordinate is the normal vector of the root coordinate, which is perpendicular to the y-axis.

[0111] It should be noted that the first vector is the direction vector corresponding to the root coordinates, which may be (0, 1). Then, based on the direction vector, the normal vector corresponding to the root coordinates is determined, and the normal vector is (1, 0).

[0112] Method 2: When the first reference coordinate is any coordinate other than the first coordinate in the reference coordinate sequence corresponding to the virtual plant, determine the second vector based on the first reference coordinate and the second reference coordinate, wherein the second reference coordinate is adjacent to the first reference coordinate, and the second vector is the direction vector from the second reference coordinate to the first reference coordinate; determine the normal vector of the second vector as the first vector.

[0113] For example, Figure 8 As shown, the first reference coordinate is C2(x1, y1), and the coordinate adjacent to C2(x2, y2) is C1(x1, y1). By calculating the coordinates C1(x1, y1) and C2(x2, y2), the difference between the horizontal coordinate and the vertical coordinate of C1 and C2 can be obtained respectively, such as: dx=x2-x1, dy=y2-y1, and then according to the difference between the horizontal coordinate and the vertical coordinate of C1 and C2 respectively, the direction vector direction between the two adjacent points of C1 and C2 is determined to be (dx, dy). It can be understood that direction (dx, dy) is the direction vector from C1 to C2, that is, the second vector. Then, according to the second vector, the normal vector normal corresponding to the second vector is calculated, that is, the first vector, and the first vector is (-dy, dx).

[0114] S5022: Determine a predicted coordinate corresponding to the first reference coordinate according to the first reference coordinate, the preset grid parameter, and the first vector.

[0115] In some embodiments, the preset grid parameter is multiplied by the first vector to obtain the first parameter, and the first reference coordinate and the first parameter are calculated to determine the predicted coordinate corresponding to the first reference coordinate.

[0116] Specifically, the predicted coordinates corresponding to the first reference coordinates include the first predicted coordinates and the second predicted coordinates, and S5032 specifically includes:

[0117] The sum of the first reference coordinate and the first parameter is determined as the first predicted coordinate, and the difference between the first reference coordinate and the first parameter is determined as the second predicted coordinate; the first parameter is the product of the preset grid parameter and the first vector.

[0118] For example, Figure 8As shown, the first reference coordinate is C2 (x1, y1), and the predicted coordinates corresponding to the first reference coordinate C2 are P3 and P4, then P3 = C2-0.5*width*normal, P4 = C2+0.5*width*normal, wherein 0.5*width is a preset grid parameter.

[0119] It should be noted that each time the predicted coordinates corresponding to the first reference coordinates are determined, the coordinate array may be determined according to the predicted coordinates corresponding to the first reference coordinates and the predicted coordinates corresponding to the coordinates adjacent to the first reference coordinates.

[0120] S503, controlling the display to simulate the animation effect of the virtual plant swaying in the wind according to the predicted coordinates corresponding to each reference coordinate in the reference coordinate sequence.

[0121] In some embodiments, based on the positional relationship between the predicted coordinates corresponding to two adjacent reference coordinates in the reference coordinate sequence, the coordinates that can constitute the basic grid or basic image in the predicted coordinates corresponding to two adjacent reference coordinates can be determined as a coordinate array, and multiple coordinate arrays can be formed into a first index sequence. The multiple coordinate arrays in the first index sequence are drawn, and the drawn image is displayed on a display, that is, the animation effect of virtual plants swaying in the wind is simulated through the display.

[0122] Specifically, S503 includes S5031 and S5032, wherein:

[0123] S5031, determining a first index sequence according to predicted coordinates corresponding to two adjacent reference coordinates in the reference coordinate sequence in a counterclockwise order, wherein the first index sequence includes a plurality of coordinate arrays, each of which includes a plurality of coordinates constituting a basic image.

[0124] In some embodiments, since the connecting line of the reference coordinate sequence corresponding to the virtual plant is a curve, it cannot be drawn in a rectangular manner, and it is necessary to use a grid for texture drawing. In OPENGL, the basic figure drawn is a triangle, and it is drawn in a counterclockwise direction. Specifically, if the current entire texture (i.e., the virtual plant) needs to be drawn with a curve, it is necessary to divide the current entire texture into several small segments, and divide the virtual plant into 50 segments in the vertical direction, each segment is a small rectangle, and a small rectangle is divided into 2 triangles. It can be understood that the predicted coordinates corresponding to two adjacent reference coordinates in the reference coordinate sequence can form a small rectangle, and each coordinate array can include the coordinates of the three vertices of one of the two triangles divided into the small rectangle. In this way, the predicted coordinates corresponding to the two adjacent coordinates can determine two coordinate arrays, and the first index sequence includes two coordinate arrays determined by the predicted coordinates corresponding to each two adjacent coordinates.

[0125] S5032: According to the first index sequence, control the display to simulate the animation effect of the virtual plant swaying in the wind.

[0126] In some embodiments, each coordinate array in the first index sequence is drawn, and the display is controlled to simulate the animation effect of the virtual plant swaying in the wind.

[0127] The embodiment of the present application can dynamically adjust the coordinate sequence corresponding to the virtual plant according to the different wind speeds, thereby realizing the dynamic adjustment of the curve of the virtual plant swaying with the wind speed. Then, according to the coordinate sequence corresponding to the virtual plant, the entire animation effect simulates and displays the swaying effect of plants in nature in real time. The swinging curve of the virtual plant also simulates the normal bending effect of the plant.

[0128] In an embodiment of the present application, the acquired wind speed and the preset index sequence are calculated to determine the reference coordinate sequence corresponding to the target element, the reference coordinate sequence includes the reference coordinates corresponding to the target element corresponding to each index in the preset index sequence, the connecting line of the reference coordinate sequence is a curve of the target element swinging with the wind speed, the reference coordinate sequence is traversed, and the predicted coordinates corresponding to each reference coordinate in the reference coordinate sequence are determined according to each reference coordinate in the reference coordinate sequence and the preset grid parameter, and the display is controlled to simulate the animation effect of the target element swinging by the wind according to the predicted coordinates corresponding to each reference coordinate in the reference coordinate sequence. In this way, the reference coordinate sequence is determined according to the acquired wind speed, and the predicted coordinates corresponding to each reference coordinate in the reference coordinate sequence are determined, and then the predicted coordinates corresponding to each reference coordinate in the reference coordinate sequence are drawn, so as to display the posture of the target element corresponding to the acquired wind speed. Furthermore, according to the different acquired wind speeds, the reference coordinate sequence obtained by the target element and the predicted coordinates corresponding to each reference coordinate in the reference coordinate sequence are also different, and different bending amplitudes of the target element can be displayed in the animation effect, and the whole picture changes with the change of wind speed, and the picture is vivid, artistic and innovative.

[0184] like Fig.11 The figure shows a schematic diagram of a display screen in an actual application scenario provided by an embodiment of the present application. The application scenario can be an art album digital art animation, in which the art animation contains multiple elements such as the sky, hills, and grass. When the wind blows, the plants will swing back and forth with the wind at a certain amplitude and frequency. When the wind speed is higher, the amplitude of the plant swing is larger; when the wind speed is lower, the amplitude of the plant swing is also smaller. The entire animation effect simulates and displays the effect of plant swaying in nature in real time, and the swinging curve also basically simulates the effect of normal bending of the plant. When there is no wind or the wind speed is very low, the plant is basically in a normal state, and the overall picture is basically displayed in a vertical direction, and the curve is not obvious. When the wind speed is higher, the plant will tilt to one side, and the entire picture is displayed in the form of a curve. Since the root of the plant is in a fixed state, the main tip swings with a larger amplitude, and drives the middle stem and leaf part of the plant to follow the swing. Since the stem and leaf part of the plant is elastic, the overall picture effect presents a periodic left and right swing effect. The entire animation effect is smooth and natural, showing the wonderful combination of animation and nature.
