[0048] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0049] It should be noted that, in the embodiments of the present invention, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a method or apparatus including a series of elements includes not only the elements explicitly recorded, but also includes other elements not explicitly listed, or also includes elements inherent to the implementation of the method or apparatus. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other related elements (such as steps in a method or modules in an apparatus, such as a module that can be a part of a circuit, a part of a processor, a part of a program or software, etc.) in the method or apparatus including the element.

[0050] For example, the scene switching method provided by the embodiment of the present invention includes a series of steps, but the scene switching method provided by the embodiment of the present invention is not limited to the steps described in this document. Similarly, the scene switching device provided by the embodiment of the present invention includes a series of modules, but the scene switching device provided by the embodiment of the present invention is not limited to including the modules explicitly described, and may also include modules required to obtain relevant information or perform processing based on the information.

[0051] The embodiment of the present invention first provides a scene switching method. For example, the method can be applied to a vehicle terminal, for example, by displaying scenes and switching scenes on a remote screen of the vehicle terminal. Alternatively, the method can also be applied to a central control screen of a vehicle terminal, or can also be applied to other terminal devices with a display screen, which is not limited by the embodiment of the present invention. The following is an example of application in a vehicle terminal:

[0052] It should be noted that the above-mentioned scene switching method can be implemented by a processor of the vehicle terminal, and the above-mentioned processor can be at least one of an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a central processing unit (CPU), a controller, a microcontroller, and a microprocessor. The embodiment of the present invention does not limit this.

[0053] Figure 1 A schematic diagram of a flow chart of a scene switching method provided by an embodiment of the present invention, such as Figure 1 As shown, the process may include steps 101 to 103:

[0054] S101, in response to a scene switching instruction, determining a target index, and searching a target scene instance from a preset database SO according to the target index;

[0055] For vehicle-mounted terminals, such as remote screens, scene displays can be provided to users. The scenes can be reflections of vehicle driving scenes, such as geographical location, weather environment, time, climate, etc., or they can be reflections of iconic geographical scenes, which are not limited here.

[0056] In some examples, the remote screen outputs scenes in the form of pictures or videos. The pictures or videos cannot be switched at multiple angles, nor can they be changed in the overall gradient part. If more scenes are required, more resources need to be configured. As the amount of resources increases, the occupancy rate of the hard disk increases, which increases the demand for vehicle-mounted hard disks, increases vehicle-mounted costs, and affects the use effect of the vehicle.

[0057] The embodiment of the present application uses full 3D technology to display the model in the scene, and based on the multi-angle change control of the model in the scene, increases the display effect, thereby meeting the scene requirements for more effects without adding more resources.

[0058] Displaying models in the scene based on 3D technology and controlling the multi-angle changes of objects in the scene increase the difficulty of managing and controlling scene resources. Packaging the resources corresponding to the scene will also increase the resource packages and cannot reduce the resource occupancy rate of the hard disk.

[0059] Based on this, the embodiment of the present application manages all resources (all resources required for the scene) by creating a class of data type. All resources of all scenes are obtained from the resource library under the class of data type, that is, only one set of resources is configured, and each scene obtains the corresponding resources from this set of resources to realize the display of the scene. The resources of the same part of different scenes can be shared, which can reduce the amount of resources; and through class management of resources, more scene instances can be created by defining the properties of components. For example, in combination with 3D technology, different perspectives of different models can be defined to obtain scene instances with various effects, or the properties of the overall gradient part of the component can be defined to obtain a scene instance with partial gradient.

[0060] As an example, the implementation method of creating a data type class to manage all resources of the scene can be:

[0061] First, all components and component properties in the scene are determined. For example, components include 3D models, special effects, animations, and specific elements, etc. Optionally, specific elements include but are not limited to the sky, the ground, mountains, the sea, etc. For example, component properties include one or more of color, position, size, display / non-display, texture, static / animation, color gradient, and gradient color mixing.

[0062] As an example, components that can be dynamically generated in the scene are also determined, such as material balls, models, prefabs, and particle effects.

[0063] Exemplarily, components and component properties in a scene may be identified in the following manner:

[0064] For example, determine whether there are weather effects such as wind, rain, and thunder in the scene, and whether there are differences in color and size depending on the environment; if there are weather effects, whether to control the playback size of the weather effects, etc.; whether there is a color gradient from the ground to the atmosphere, and whether different scenes have different gradient effects, etc.

[0065] It should be noted that the components listed above are components and component attributes in a scene under a model. In other models, other types of components and component attributes may also be included, which are not limited here.

[0066] Then create a class of the data type, define all components and component attributes in the scene as class attributes, define the parameters of the component attributes, and create a scene instance of the class. It should be noted that the combination of different components, the combination of different component attributes and / or the parameter settings of different component attributes can create scene instances of various effects.

[0067] In the exemplary embodiment, the parameter of the component attribute refers to the numerical value of the component attribute. For example, for the color attribute, the corresponding parameter is the RGB value, for the position attribute, the corresponding parameter is the coordinate value, and for the special effect attribute, the corresponding parameter can be the special effect configuration information, etc.

[0068] Furthermore, after completing the components of the class, defining the component attributes, and creating the scene instance, the attributes and behaviors of the scene instance are managed and operated based on the control script (ie, the program of the display control module is set).

[0069] In this embodiment, this class contains the component properties of each component in the scene. According to different components, the relevant property controls are made specifically, including but not limited to the following examples:

[0070] For example, the attributes of the scene 3D object include color, position, size, texture, and texture sampling method, and the control of color, position, size, texture, and texture sampling method is correspondingly produced.

[0071] As an example, the texture and sampling method and whether it is object space sampling / screen space sampling need to be written in a separate script and controlled by this system.

[0072] For example, the properties of the weather effect object include color, whether to play, and the control value of the play size. This corresponds to the control values ​​of the color, whether to play, and the play size of the weather effect. As an example, another script can be written and controlled by the control script of this class.

[0073] Exemplarily, the attributes of the sky gradient include the colors of each gradient layer, and the corresponding attributes control how the colors are mixed and what the mixing ratio is.

[0074] In this example, for the gradient color mixing method, you can select the corresponding screen overlay method according to the desired effect (different overlay methods achieve different effects):

[0075] As an example, the gradient color mixing may adopt additive mixing (Blend One One, additive mixing). Additive mixing refers to adding two colors. For example, for the sky gradient presenting a lighting effect or a luminous effect, the gradient color mixing is realized by additive mixing.

[0076] As an example, gradient color mixing can also use Alpha mixing (Blend SrcAlphaOneMinusSrcAlpha, Alpha mixing). Alpha mixing refers to mixing based on the Alpha value of the source color and the (1-Alpha) value of the target primary color. For example, the sky gradient presents a transparent effect, and Alpha mixing is used to achieve gradient color mixing.

[0077] Exemplarily, the attributes of the ground include ground color or partial color, sampling size, Fresnel color, normal map and normal sampling rate, and the attribute control is partial color, sampling size value, whether Fresnel color changes, whether normal map changes, normal sampling rate value, etc.

[0078] It should be noted that Fresnel color refers to the color effect that changes with the viewing angle. It is implemented in the shader through the Fresnel function, and its parameters can be controlled by scripts to change the Fresnel color; the normal map is used to simulate surface details to make it look more bumpy; the normal sampling rate refers to the frequency at which the normal information in the normal map is sampled to adjust the bumpy detail effect of the surface.

[0079] As an example, for the setting of the control script, you can add, modify or delete some new personalized features according to the needs of independent scenes, limit the parts that need to be controlled separately, such as model special effects, and strip related properties for personalized control. In each class, turn this item on or off or enumerate it and make adjustments as needed.

[0080] After the creation of the above classes is completed, the classes of the above custom data types are created as a local static database SO, that is, a preset database SO.

[0081] The SO database is static and can be adjusted as needed due to scene art design when the system is not running. It can also be adjusted in real time according to the display effect during operation. All operation traces will be permanently retained in the SO database.

[0082] Exemplarily, all the data defined above (including components, component attributes, parameters of component attributes, etc.) are converted into float4 data or enumeration Enum data is defined and stored as a local static database for calling.

[0083] Due to the large number of scene changes and scene effects, the database SO contains a lot of data. In order to facilitate management and quick data call, the database SO is serialized and a corresponding index is generated based on each scene instance. When the remote screen switches scenes, the corresponding scene instance can be queried in the database SO based on the index.

[0084] In this embodiment, the above-established database SO is set in the scene switching device, or in the vehicle terminal, so as to be called by the display screen control device of the vehicle terminal.

[0085] Taking the remote screen of the vehicle terminal as an example, the database SO is added to the hard disk of the vehicle terminal so that the remote screen can call the corresponding data when displaying the scene.

[0086] As an example, configure the remote screen scene switching control, search for the corresponding scene instance based on the scene index, and then call the corresponding scene data when the scene is switched. That is, in this step, the target index refers to the index of the target scene instance. Exemplarily, the scene instance name, scene instance identifier or scene instance ID can be used as the index of the scene instance.

[0087] The scene playback methods of the remote screen include but are not limited to the following two:

[0088] In an optional implementation, the remote screen provides a preview playback scene. In this playback mode, the remote screen switches scenes based on a preset time interval and in a preset order. Therefore, in this playback mode, if the display time of the current scene reaches the preset time interval, the scene switching instruction is automatically triggered. In response to the scene switching instruction, the next scene index of the current scene index is determined based on the preset scene playback order, and the next scene index is the target index.

[0089] In an optional implementation, the remote screen provides a scene playback according to the vehicle driving scene. In this playback mode, the remote screen triggers a scene switching instruction based on the vehicle driving mode, the vehicle environment, climate, time and other driving scene information. And the target index of the next target scene to be played is determined based on the above driving scene information. For example, when the vehicle is in normal driving mode from 12 noon to 2 o'clock, scene 1 is played accordingly. When the vehicle is in normal driving mode from 2 o'clock to 4 o'clock in the afternoon, scene 2 is played accordingly. When the current time reaches 2 o'clock in the afternoon and the vehicle has been in normal driving mode, the scene switching instruction is triggered, and the index of scene 2 is determined as the target index.

[0090] In an optional implementation, the remote screen provides a scene change representation under a fixed model, that is, within a preset time, in the scene fixed mode, the decoration model in the scene changes over time. In this playback mode, the scene switching instruction is triggered based on the set time point, and the target index is determined based on the scene index corresponding to the set time point.

[0091] It should be noted that the scene switching instruction may also be triggered in other ways, such as manual triggering by a user, which is not limited here.

[0092] After the target index is determined, the corresponding target scene instance can be found based on the preset database SO.

[0093] S102, obtaining target component information of the target scene according to the target scene instance;

[0094] In this step, the component information includes components, component attributes, and parameters of component attributes. In the database SO, each scene instance defines the components, component attributes, and parameters of component attributes contained in the scene. Therefore, after finding the target scene instance in the database SO, the target component information required for the target scene can be obtained based on the target scene instance.

[0095] For example, scene 1 includes component 1, component 2, the colors of component 1 and component 2, RGB values ​​of the colors of component 1 and component 2, etc., which are target component information.

[0096] In an optional implementation, in order to reduce the amount of data in the database SO, and based on the fact that components in certain scenarios can be generated in real time, when creating a scenario instance, the parameters corresponding to these components can define the component configuration information, and then set the corresponding generation control. At runtime, the component is dynamically generated based on the configuration information.

[0097] Exemplarily, S102 may include:

[0098] A1: Obtain first component information and first component configuration information according to the target scenario instance;

[0099] A2: Generate a second component according to the second component configuration information, wherein the target scenario instance defines the first component information and the second component configuration;

[0100] A3: Based on the first component information and the second component, obtain the target component information.

[0101] It should be noted that the first component information is pre-configured in the database, such as 3D models, RGB values ​​of the 3D model's colors, position coordinate values, etc. The first component configuration information refers to the configuration information of the component preset in the database, and the system can generate the component according to the component configuration information. For example, for some special effect components, since the characteristics can be dynamically generated in real time, the corresponding special effect component configuration information for the scene is defined in the scene instance. When the scene is running, the special effect component configuration information is called to dynamically generate the special effect component without pre-configuration in the database, so as to avoid excessive data volume in the database, affecting the loading speed and increasing the space occupied by the database.

[0102] After the second component is generated, the first component information and the second component are the target component information corresponding to the target scene. In some examples, the target scene instance is updated based on the target component information and saved in the database. The next time the target scene is run, the updated component information can be directly called to directly display the scene. That is, the same special effect component can be dynamically generated when it is displayed for the first time, and the dynamically generated feature component can be saved to the scene instance corresponding to the database. It can be called repeatedly without generating it every time, which can speed up the scene switching speed.

[0103] Alternatively, in some examples, after the second component is generated, the scene instance in the database is not updated, and the second component is generated each time using the second component configuration information without occupying the database.

[0104] S103: Switch to the target scene based on the target component information.

[0105] In this step, after obtaining the target component information, the remote screen can switch scenes according to the target component information and display the target scene.

[0106] In this embodiment, on the one hand, all data resources of the scene to be displayed are packaged into a class to form a set of data resources, and this set of data resources is managed through the class. All scenes obtain the corresponding required data from this set of data resources to realize the display of the scene. Compared with the resources corresponding to the scene being packaged into data packets, the resources in this embodiment can be shared and the amount of resources can be reduced; on the other hand, data resources are managed based on the class of data type, and data resources can be better deployed and applied; on the other hand, this embodiment uses full 3D technology to display the model in the scene, and the scene display effect can be increased through multi-angle display effects, hierarchical gradients, partial gradients, etc. of the model. That is, without adding components to the scene, the display effect and scene changes can be enriched by adding component attributes or component attribute values.

[0107] Exemplarily, it is applied to certain scene functions of the remote screen to achieve better results. For example, in some scene functions, based on a fixed model, it is required to display the changing performance of the overall scene within a preset time period. In this example, a fixed model refers to a structure that remains unchanged in all scenes, such as a terrain model. Changes in different scenes are achieved by switching the decorative models in the scene. In this scene function, many resources can be shared, and for the decorative model, the scene can be created by creating a scene instance under the class. Not only does the resource data occupy less space on the hard disk, but there are also fewer adjustments to the data when adding scenes. In addition, with the control of multiple time periods, scenes corresponding to time changes can be realized, providing users with visual effects of scenes that match the current time.

[0108] Exemplarily, the embodiments of the present invention control the display of components from multiple angles to further enrich the scene effects. For example, the control of the model in the scene (color, size, texture change), color change, size change and texture change, present different effects. For example, the special effects in the scene (color, size, area, whether to display, color can be switched gradually) are controlled, the animation in the scene is controlled (whether there is animation, whether to play, whether the animation object has size scaling), the sky (color, several layers of gradient, whether there are clouds, whether there is fog) and the mountain model (texture change, color change, whether to hide, whether the size of the bumps is distinguished, whether there are other effects) are controlled separately, not only can it be gradient, but it can also be gradient in multiple layers.

[0109] Figure 2 FIG. 2 is a flow chart showing another embodiment of the scene switching method of the present invention, which is executed by an electronic device. Figure 2 As shown, the method comprises the following steps:

[0110] S201: In response to a scene switching instruction, determine a target index, and search for a target scene instance from a preset database SO according to the target index.

[0111] S202: Obtain target component information of the target scene according to the target scene instance.

[0112] Among them, the specific implementation method of S201 and S202 is the same as above Figure 1 The specific implementation methods of S101 and S202 are the same, and the details may refer to the above embodiments, which will not be described here.

[0113] S203, based on the target component information, updating the current component information controlled by the display control module, so as to switch to the target scene under the control of the display control module.

[0114] In this embodiment, a custom method SetTargetTime(int Index) is created in the control program. By calling this method, the update of the current component information of the control module is implemented according to the passed-in index value. SetTargetTime(int Index) acts as an interface, which implements the switching of scenes according to the passed-in index value without changing or switching the control module (control program) of the scene display. Therefore, when a scene instance is added or modified in the database SO, the control program needs to be modified or updated accordingly. The display control and the scene instance are controlled separately and independently without affecting each other. At the same time, the association between the display control and the scene instance can be realized based on SetTargetTime(int Index).

[0115] As an example, since the target component information includes many types, when updating the current component information, the data update method can also adopt different methods according to different data types, thereby achieving different switching effects. For example, when the scene switches, corresponding to the change of different colors or different positions of the same part, or the change of gradient, the smooth switching effect provides a better visual effect.

[0116] Therefore, illustratively, step S203 further includes:

[0117] B1: parameters that identify the properties of the target component;

[0118] B2: When the parameter of the target component attribute is a linear value, the parameter of the corresponding current component attribute is updated based on the linear interpolation algorithm according to the parameter of the target component attribute and the parameter of the corresponding current component attribute;

[0119] Based on the linear interpolation algorithm, the numerical value of the target scene is inserted into the display control module to achieve smooth processing of the display and improve the scene switching effect.

[0120] B3: If the parameter of the target component attribute is a nonlinear value, the corresponding current component attribute is replaced based on the target component attribute.

[0121] If the parameter type of the target component attribute is a nonlinear value, the current component attribute controlled by the display control module is replaced based on the target component attribute. For nonlinear values, linear interpolation cannot be used, so it is directly replaced to achieve scene switching.

[0122] The following examples illustrate which component properties and values ​​are smoothed based on linear interpolation and which component properties and values ​​are directly replaced:

[0123] When switching from the current scene CurrentIndex to the target scene TargetIndex, the color Color, position Vector3, texture sampling value Value and size Scale of the same model are linear values. For the switching between the target scene's value and the current scene's value, the linear value uses Mathf.Lerp(A,B,Time.deltaTime) and other interpolation to smoothly gradient the values ​​between the two scenes to achieve a smooth gradient effect. During the scene switching process, the smooth gradient switching effect is displayed.

[0124] For nonlinear images and enumerations of the same model, the target image is directly inserted into the corresponding position of the display control module and replaced when switching.

[0125] For the linear unit color, particle size, emission frequency, life cycle and other parameters of the weather system special effects, Mathf.Lerp(A,B,Time.deltaTime) and other interpolation methods are also used to smoothly gradient the values ​​between the two scenes to achieve a smooth gradient effect. During the scene switching process, the weather special effects display a smooth gradient effect.

[0126] For non-linear material maps, masks, dissolve effects, etc., the corresponding preset values ​​are matched and switched, and the particle playback is closed and replayed when switching to achieve a smooth gradient effect.

[0127] For the sky, all the multiple layers of Color are linear colors. Similarly, for the switching between the target scene and the current scene, the values ​​between the two scenes are smoothly gradient processed through interpolation such as Mathf.Lerp(A,B,Time.deltaTime).

[0128] For the cloud Cloud, in addition to the color part, you can do linear gradient and switch according to different superposition methods (for specific superposition methods, refer to the above Figure 1 Example), the Enum part needs to define different blending methods, switching between CurrentIndex and TargetIndex, and black / white clouds and thin / thick cloud effects will appear.

[0129] The ground part is switched and adjusted with the model, different attributes are distinguished, and then different change methods are used to change them.

[0130] In this embodiment, on the one hand, through the custom method SetTargetTime(int Index), it is possible to complete the update of the current component information controlled by the display control module based on the passed-in index value, and realize scene switching without modifying or updating the display control module. In this way, when adding or modifying scenes in the system, there is no need to upgrade the display control module; on the other hand, in the component information update process, different insertion methods are selected according to the parameter type of the component attribute. For parameters that can be smoothly inserted, smooth processing is adopted to make the scene switching effect better. For parameters that cannot be smoothly inserted, replacement is adopted to make the scene switching adapt to the update and insertion of different types of component information.

[0131] Based on the above embodiments, the scene switching method provided by the embodiments of the present invention may further include: Figure 3 The process shown, Figure 3 A flow chart of an embodiment of the present invention for updating the current component information controlled by the display control module based on the target component information is shown in FIG. Figure 3 As shown, the process may include steps S301 to S302:

[0132] S301, comparing the target component information with the current component information controlled by the display control module, and determining the changed component information different from the current component information;

[0133] In the database SO, the component information corresponding to the scene instance stored is all the component information of the scene instance, wherein the component information corresponding to different scene instances may be partially the same. This step determines the corresponding changed component information when switching from the current scene to the target scene by comparing the component information.

[0134] For example, both scene 1 and scene 2 have 3D model 1 and special effect 1. The positions of the 3D models in scene 1 and scene 2 are the same, but the colors are different. Special effect 1 of scene 1 is on, and special effect 1 of scene 2 is off. When switching from scene 1 to scene 2, the component information in the scene 2 example includes 3D model 1, 3D model 1 position A1, 3D model 1 color C2, special effect 1, and special effect 1 off. The current scene (scene 1) displays 3D model 1, 3D model 1 position A1, 3D model 1 color C1, special effect 1, and special effect 1 on. By comparing scene 1 and scene 2, it can be determined that the different component information is the status of the color and special effects of 3D model 1, so it can be determined that the status of the color and special effects of 3D model 1 is the changing component information.

[0135] S302: Based on the changed component information, update the current component information controlled by the display module.

[0136] The changed component information is inserted into the current component information controlled by the display control module. The component information that is the same as the target scene and the current scene remains unchanged, and only the changed component information is updated.

[0137] In this embodiment, when the scenes are switched, the same parts of the current scene and the target scene are kept unchanged, and only the different parts are switched, which can reduce the calling and switching of data.

[0138] Based on all the above embodiments, the scene switching method provided by the embodiment of the present invention may also include: Figure 4 The process shown, Figure 4 A schematic diagram of a process for adjusting component information of a scene during scene switching provided by an embodiment of the present invention, such as Figure 4 As shown, the process may include steps S401 to S403:

[0139] S401, upon receiving a component information adjustment instruction for the current scene, obtaining component information to be adjusted;

[0140] In this step, the adjustment instructions can be created after the above Figure 1 After the database SO of the embodiment is created, it is triggered when the art designer adjusts the scene instance in the database SO, for example, the adjustment instruction includes modifying or adding component attributes or component attribute values, etc. Alternatively, a scene instance may be added.

[0141] Alternatively, the adjustment instruction may be an adjustment triggered when the scene is running. For example, the remote screen provides a scene preview interface, and the scene preview interface provides a scene adjustment control. The user or art designer may trigger the adjustment instruction through the scene adjustment control, and adjust the current scene displayed through the scene adjustment control or the adjustment interface output when the scene adjustment control is triggered.

[0142] The adjustment instruction includes component information to be adjusted, and the component information to be adjusted may be all component information of the scene instance or part of component information of the scene instance.

[0143] S402, updating component information of the current scene based on the component information to be adjusted to form a new scene instance;

[0144] S403, save the new scene instance in the index of the current scene in the database SO.

[0145] After the component information of the scene instance is adjusted, the component information of the scene instance is updated and saved in the database so that it can be directly called and used next time.

[0146] As an example, if all component information in a scene is adjusted, then after all component information in a scene has been adjusted, the scene attribute class of the SO is copied as a whole and saved in the index corresponding to the SO, replaced, and the SO database is updated.

[0147] In this embodiment, since the display control program and the database SO are independent parts, a function for modifying the scene instance of the database SO is provided. The modification of the scene display effect does not affect the display control program, thereby realizing the decoupling of art design and scene display control, increasing the flexibility of scene setting, and allowing adjustments according to different needs at different times to enhance user experience.

The replacement module is used to replace the corresponding current component attributes based on the target component attributes when the parameters of the target component attributes are identified as non-linear values.

[0154] In an optional manner, the scene switching module also includes a comparison module, which is used to compare the target component information and the current component information controlled by the display control module to determine the changed component information that is different from the current component information; the update module is also used to update the current component information controlled by the display control module based on the changed component information.

[0155] In an optional manner, the acquisition module includes a calling module and a generating module. The calling module is used to call the first component information and the second component configuration information according to the target scene instance; the generating module is used to generate the second component according to the second component configuration information, and obtain the target component information based on the first component information and the second component.

[0156] As can be seen from the above, the scene switching device provided by the embodiment of the present invention can not only reduce the occupation rate of scene resources on hardware, but also enrich the scene display effect through multi-angle changes, color gradients, partial color gradients, etc. of 3D models without increasing scene resources. And through the combination of components, component attributes and component attribute values, effects such as seasonal changes, 24-hour changes, and weather changes can be generated.
