[0043] Vehicle entertainment or infotainment is a collection of hardware and software that provides audio or video entertainment in a vehicle. In a vehicle infotainment screen, the effect of air blowing of an air conditioner is generally displayed by a graphic or dynamic effect, so as to intuitively display the air blowing effect of the air conditioner to a user.

[0044] However, the graphic or dynamic effect for displaying the air blowing effect of the air conditioner in the prior art is generally a pre-made effect picture or dynamic effect file, that is, the effect is displayed by pre-storing a resource file in the system. If it is desired to update the graphic or dynamic effect, it needs to be completed by a developer, which results in that the effect is difficult to modify or change.

[0045] Therefore, the present inventors consider that the air blowing dynamic effect of the air conditioner can be realized by using a real-time 3D interactive content creation tool, an overall framework can be first made, and then the blowing effect can be controlled by modifying parameters of the wind. For example, the display effect of the blowing air flow can be controlled by setting parameters such as flow speed, swing amplitude and color of the blowing air flow. Compared with the prior art of displaying the blowing air flow effect by pre-storing a resource file in the system, the display effect of the blowing air flow is more easily operated when displayed and changed, and the problem of the prior art that the air blowing effect is difficult to change is solved.

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] Referring to Figure 1 , Figure 1 A flowchart of a display method for blowing air flow provided by an embodiment of the present application is shown in FIG. 10, which comprises the following steps.

[0048] Before step S101, a real-time 3D interactive content creation tool can be used to realize the air blowing dynamic effect of the air conditioner. The real-time 3D interactive content creation tool can adopt a Unity3D engine. First, an overall framework needs to be built. In the built framework, parameters can be modified, and the display effect of the blowing can be adjusted by modifying the parameters.

[0049] S101, set a flow speed and a swing amplitude of the air flow.

[0050] The embodiment of the application can use one airfoil to simulate the wind effect, and the up-down swing of the wind can be achieved by moving each vertex coordinate on the airfoil. Considering that the swing of the airfoil has randomness and is continuously changed, the change of the airfoil can be controlled according to the set wind speed and swing amplitude. Therefore, the flow speed and the swing amplitude of the air flow are set.

[0051] S102, display the position change of the air flow by using the flow speed and the swing amplitude of the air flow.

[0052] In step S101, the flow speed and the swing amplitude of the air flow are set, the flow speed of the air flow is used to reflect the speed of the air flow, the swing amplitude of the air flow is used to reflect the distance of the position change of the air flow, and the position change of the air flow is simulated by the flow speed and the swing amplitude of the air flow, and the simulated position change of the air flow is visually displayed.

[0053] S103, set the color of the air flow, the color including a first color and a second color.

[0054] The display effect of the air flow includes not only the display of the position change, but also the display of the shape and the color of the air flow, so that the shape and the position of the air flow can be displayed by setting the color of the air flow. The color of the air flow can be set as a first color and a second color, the first color can be used as a basic color, and the second color can be used as an adjusting color.

[0055] S104, display the shape and the color change of the air flow by using the gradient disturbance between the first color and the second color.

[0056] According to the setting of step S103, the first color is a basic color, and the second color is an adjusting color. The gradient disturbance between the basic color and the adjusting color is used to display the shape and the color change of the air flow. For example, the outline of the wind can be outlined by using the gradient between the basic color and the adjusting color, so as to achieve the effect of displaying the shape of the air flow by using the gradient disturbance between the basic color and the adjusting color. Moreover, the gradient disturbance between the basic color and the adjusting color can reflect the color change of the air flow.

[0057] The embodiment of the present application provides a display method of air flow. In the execution of the method, first, the flow speed and swing range of the air flow are set; then the position change of the air flow is displayed by using the flow speed and swing range of the air flow; the color of the air flow is set, and the color includes a first color and a second color; finally, the change of the shape and color of the air flow is displayed by using the gradient disturbance between the first color and the second color. In this way, the display effect of the air flow is controlled by setting the flow speed, swing range, color and other parameters of the air flow, compared with the prior art, the display effect of the air flow is more easily operated when being displayed and changed in the system by using the preset resource file, and the problem that the air flow display effect is changed more complicatedly in the prior art is solved.

[0058] Further, in the optional embodiment of the present application, the density of the air flow is different at different positions in the flow process, the density of the air flow can be simulated by setting the gradient and transparency effect, and specifically, the density of the air flow can be simulated by setting the gradient parameter and the transparency parameter of the color of the air flow. For example, the color at the position with large density of the air flow is set to be deep, the color at the position with small density of the air flow is set to be shallow, and the change of the density of the air flow is reflected by the gradient of the color depth; and the density of the air flow can be simulated by adjusting the transparency parameter. For example, the transparency at the position with large density of the air flow is low, and the transparency at the position with small density of the air flow is high. In this way, the density of the air flow is simulated by setting the gradient parameter and the transparency parameter of the color of the air flow, so that the display effect of the air flow is more easily adjusted.

[0059] Further, in the optional embodiment of the present application, in the implementation method for simulating the density of the air flow by setting the gradient parameter of the color of the air flow, the gradient parameter of the color of the air flow can be set as a vertical gradient parameter and a horizontal gradient parameter, and the density of the air flow is displayed by using the vertical gradient parameter, the horizontal gradient parameter and the transparency parameter. For example, the change of the air flow can be divided into vertical change and horizontal change, so that the vertical density of the air flow is simulated by using the vertical gradient parameter, and the horizontal density of the air flow is simulated by using the horizontal gradient parameter.

[0060] Further, in the optional embodiment of the present application, the scheme provided by the embodiment of the present application can be applied to the display of the air flow of the air conditioner in the car entertainment screen, in this application scenario, the background color of the air outlet can be set, and the gradient background color can also be set, and the background color of the air outlet is displayed together when the state of the air flow is displayed.

[0061] Further, in the optional embodiment of the present application, the above-mentioned embodiment mentions that one wind blade can be used to simulate the wind effect, and the up-and-down swing of the wind can be achieved by moving each vertex coordinate on the wind blade; considering the randomness of the swing of the wind blade, a noise map can be used to simulate the swing floating; and the swing of the wind is continuous, and the random displacement change of the wind blade in each frame can be realized by setting the Tiling and Offset of the noise map to change with time. The noise can be understood as recording a value with black and white information, and then returning the value to the corresponding attribute, and the noise can be used to affect the position. The Tiling and Offset are two attributes in the Unity material map. The Offset indicates the starting position of using the map, and the value range is 0-1; the Tiling indicates the size of the region from the Offset position, and the value range of the region is generally (-1, 1), and the part exceeding the range will be proportionally generated to splice the previous region.

[0062] The above is some specific implementation manners of the method for displaying the blowing air flow provided by the embodiments of the present application, based on which, the present application further provides a corresponding device for displaying the blowing air flow.

[0064] The first setting module 201 is specifically used for setting the flow speed and swing amplitude of the blowing air flow.

[0065] In the embodiments of the present application, one wind blade can be used to simulate the wind effect, and the up-and-down swing of the wind can be achieved by moving each vertex coordinate on the wind blade; considering the randomness of the swing of the wind blade, a noise map can be used to simulate the swing floating; and the swing of the wind is continuous, and the random displacement change of the wind blade in each frame can be realized by setting the Tiling and Offset of the noise map to change with time. The noise can be understood as recording a value with black and white information, and then returning the value to the corresponding attribute, and the noise can be used to affect the position. The Tiling and Offset are two attributes in the Unity material map. The Offset indicates the starting position of using the map, and the value range is 0-1; the Tiling indicates the size of the region from the Offset position, and the value range of the region is generally (-1, 1), and the part exceeding the range will be proportionally generated to splice the previous region.

[0066] The first display module 202 is specifically used for displaying the position change of the blowing air flow by using the flow speed and swing amplitude of the blowing air flow.

[0067] The first setting module 201 sets the flow speed and swing amplitude of the blowing air flow. Through the first display module 202, the flow speed of the blowing air flow is used to reflect the speed of the blowing air flow; the swing amplitude of the blowing air flow is used to reflect the distance of the movement of the blowing air flow position; the flow speed and the swing amplitude of the blowing air flow are used to simulate the position change of the blowing air flow, and the simulated position change of the blowing air flow is visually displayed.

[0068] The second setting module 203 is specifically configured to set the color of the blowing air flow, and the color includes a first color and a second color.

[0069] The display effect of the blowing air flow includes the display of the shape and the color of the blowing air flow in addition to the display of the position change, so that the shape and the position can be displayed by setting the color of the blowing air flow through the second setting module 203. The color of the blowing air flow can be set as the first color and the second color, the first color can be used as a basic color, and the second color can be used as an adjusting color.

[0070] The second display module 204 is specifically configured to display the shape and the color change of the blowing air flow by using the gradient disturbance between the first color and the second color.

[0071] According to the setting of the second setting module 203, the first color is a basic color, and the second color is an adjusting color. The shape and the color change of the blowing air flow are displayed by using the gradient disturbance between the basic color and the adjusting color through the second display module 204. For example, the outline of the wind can be outlined by using the gradient between the basic color and the adjusting color, so as to achieve the effect of displaying the shape of the blowing air flow by using the gradient disturbance between the basic color and the adjusting color. The color change of the blowing air flow can be reflected by the gradient disturbance between the basic color and the adjusting color.

In this way, the display effect of the blowing air flow is controlled by setting the flow speed, the swing amplitude, the color and other parameters of the blowing air flow. Compared with the prior art, the blowing air flow effect is displayed by pre-setting a resource file in the system. The display effect of the blowing air flow is easy to operate when it is displayed and changed, and the problem that the blowing effect of the air conditioner is difficult to change in the prior art is solved.

Specifically, the density of the blowing air flow can be simulated by setting the gradient parameter and the transparency parameter of the blowing air flow color. For example, the color at a position with a large density of the blowing air flow can be set to be darker, and the color at a position with a small density of the blowing air flow can be set to be lighter. The change in the density of the blowing air flow is reflected by the gradient of the color depth. The density of the blowing air flow can also be simulated by adjusting the transparency parameter.
