The term "one embodiment" means "at least one embodiment," the term "another embodiment" means "at least one additional embodiment," and the term "some embodiments" means "at least some embodiments."

[0051] The embodiment of the present application provides a display method. The styles displayed on the existing vehicle instrument display screen are basically fixed. Even if there are replaceable three-dimensional car models, they are of several types inherent in the vehicle when it leaves the factory. Some users hope to have more types of three-dimensional car models to choose from. Therefore, the types of three-dimensional car models in the existing vehicle instrument display screen cannot meet the users' replacement needs.

[0052] The present application provides a display method, device, vehicle and storage medium, which can replace the style of the three-dimensional car model in the instrument display screen, meet the user's personalized setting needs, and improve the user's driving experience.

[0053] Example 1

[0054] See also Figure 1 , Figure 1 The flowchart of the display method provided in the embodiment of the present application includes:

[0055] S101: Acquire format data of the target model.

[0056] The target model is the model that will be displayed on the instrument display screen after the user selects it in the theme mall. When the user selects the target model, the instrument human-computer interaction interface will download the file package of the target theme and obtain the format data corresponding to the target model.

[0057] After parsing the configuration file, the name and storage path corresponding to the target model will be obtained. According to the name and storage path, the storage file of the target model can be obtained in Obj format. Figure 2 , Figure 2 This is a model Obj format example provided in an embodiment of the present application. The format data can be obtained after manually parsing the file.

[0058] S102: Writing the format data into a preset field of a model data template to obtain model data of the target model.

[0059] Before building a three-dimensional car model, it is necessary to build a model data template. The model data template has a reserved position corresponding to the format data. After obtaining the format data corresponding to the target model, the format data needs to be written into the preset field of the model data template to obtain the complete model data corresponding to the target model.

[0060] It should be noted that the model data template consists of two parts, one part is a fixed and unchangeable field, and the other part is a changeable field, which is a preset field. When changing the model, you only need to write the format data of the target model into the preset field.

[0061] S103: Rendering the target model according to the model data of the target model, and displaying the target model in the interface of the vehicle instrument.

[0062] After obtaining the model data corresponding to the target model, the target model needs to be rendered, that is, the original car model is replaced with the target model, and the target model is converted from the form of data model data to a grid state to replace the original model.

[0063] In one implementation of the embodiment of the present application, the format data includes:

[0064] Vertex data, texture data, normal data, and face data;

[0065] Writing the format data into a preset field of the model data template includes:

[0066] Writing the vertex data into the vertex field of the model data template;

[0067] Writing the texture data into the texture field of the model data template;

[0068] Writing the normal data into the normal field of the model data template;

[0069] The face data is written into the face field of the model data template.

[0070] After decompressing the target model's configuration file, the target model's name and storage path are obtained. This storage path allows the corresponding Obj file to be retrieved. Parsing this file yields the corresponding format data, including vertex data, texture data, normal data, and face data. It should be noted that 3D models can be in Obj file format, requiring manual parsing to generate custom format data. A 3D model is composed of vertex data, face data, normal data, and textures. In the parsed Obj file, "v" represents vertex data, "vt" represents vertex texture data, "vn" represents vertex normal data, and "f" represents face data. A face is composed of vertex data, texture data, and normal data, for example: fv1 / vt1 / vn1 v2 / vt2 / vn2 v3 / vt3 / vn3...

[0071] It is understandable that the texture data has two coordinate axes, U and V, and is therefore called UV coordinates. The "UV" in three-dimensional modeling can be understood as the "skin" of a three-dimensional model. The "skin" is unfolded and then drawn on a two-dimensional plane and assigned to the object. Each point on the image is accurately mapped to the surface of the model object, and the gaps between points are smoothly interpolated by the software. The process of creating a model of the target subject according to the format data goes through the "UV mapping" and "UV unfolding" processes, where UV mapping is a planar representation of the surface of a three-dimensional model for easy packaging of textures. The process of creating UV mapping is called UV unfolding, which is based on modeling polygonal meshes. After "UV mapping" and "UV unfolding", the mesh properties are dynamically set to achieve the purpose of switching models.

[0072] After obtaining the data required to construct the three-dimensional model, the vertex data is written into the vertex field of the model data template, the texture data is written into the texture field of the model data template, the normal data is written into the normal field of the model data template, and the surface data is written into the surface field of the model data template, for example Figure 3 The model data example diagram in , from which the model data corresponding to the target model can be obtained.

[0073] In one implementation of the present application, the preset model data template is a model data template dynamically created via the Kanzi interface. The model data template is dynamically created via the Kanzi interface, and the format data required for model creation is written into the model data template. Dynamically creating a model data template means that different dynamically created model data templates can be created for different Obj format files to enable the replacement of different styles of 3D vehicle models.

[0074] In one implementation of the embodiment of the present application, obtaining the format data of the target model includes:

[0075] Get the configuration file of the target model;

[0076] The configuration file is automatically parsed to obtain the storage path of the target model, and the format data is obtained by manually parsing the file corresponding to the storage path.

[0077] When the user downloads and uses a new 3D model, the instrument human-machine interface will parse the new skin configuration file to obtain the specific location where the target model is stored and the name of the model. The Obj file of the model can be found according to the storage path and the corresponding model name. After manual parsing, the following can be obtained: Figure 3 Obj file of a model shown.

[0078] In one implementation of the embodiment of the present application, creating the target model according to the model data of the target model includes creating a grid structure corresponding to the target model according to the model data, setting the grid structure using the set Property method, and creating the target model. Figure 3 The example model format shown in the figure also requires creating a mesh based on the model data to obtain the final display form of the target model. It should be noted that in addition to the car model, the 3D model can also include a 3D virtual portrait, a dial display, and various 3D images. The specific form can be set according to the user's personal preference and is not specifically limited here.

[0079] The above embodiment provides a display method. When executing the method, the format data of the target model is first obtained, and the format data is written into a preset field of the model data template to obtain the model data of the target model. Then, based on the model data of the target model, the target model is rendered and displayed on the display screen of the vehicle instrument, so that the user can replace the model on the vehicle instrument display screen according to personal preference. In this way, by obtaining the format data of the target theme and creating a three-dimensional vehicle model based on the format data, the effect of being able to replace the three-dimensional vehicle model is achieved. In this way, the user's driving experience can be enhanced.
