[0029] Step 106: Synthesize the content to be displayed into a holographic image and output it based on the camera target texture rendering technology and the output form of the holographic projection device.

[0030] In this embodiment, by pre-constructing the three-dimensional model of the product and superimposing the constructed three-dimensional model and product characteristics into the holographic projection scene, a display form combining static and dynamic can be formed. Furthermore, the representation of the product characteristic data is elevated from a simple planar form to a three-dimensional form combined with a three-dimensional model, intuitively revealing the correlation between product characteristics and target pose changes, and significantly improving people's understanding of product characteristic data.

[0031] The following describes Figure 1 the execution manners of the steps shown.

[0032] First, for step 100, constructing a holographic scene and importing the three-dimensional model of the product to be displayed into the holographic scene, includes:

[0033] Based on a camera system, a 360-degree holographic scene in all directions of front, back, left, and right is established. The background of the holographic scene remains completely black and is added with predetermined lighting and special effects. The camera system includes four sub-cameras and one main camera.

[0034] Estimate the viewing distance and viewing height of the audience based on the size of the holographic projection device.

[0035] Based on the estimated viewing distance and viewing height, determine the specific positions of each camera in the camera system.

[0036] Based on the specific positions of each camera, determine the perspective relationship and scale size of the three-dimensional model of the product to be displayed in the holographic scene.

[0037] Import the three-dimensional model of the product to be displayed into the holographic scene and adjust the three-dimensional model to the central position of the four sub-cameras.

[0038] In this embodiment, the size of the holographic projection device is determined according to the actual situation. The viewing distance and viewing height can be 6 meters and 1.5 meters respectively, and no specific limitation is made here. In addition, during the process of importing the model into the holographic scene, attention should be paid to the size ratio and animation effect of the model.

[0039] For step 102, manage the associated data loaded in the holographic scene based on user requirements. The associated data includes three-dimensional model data, basic characteristic data, and scattering radiation data.

[0040] In some embodiments, the three-dimensional model data includes: three-dimensional model mesh file data and three-dimensional model material data. During parsing, integrate the three-dimensional model mesh data and three-dimensional model material data to generate three-dimensional objects of each component and structure of the product to be displayed. Among them,

[0041] (1) The three-dimensional model mesh file data includes: model file path data, model object name, type data and preset data, coordinate data of the model object in the three-dimensional world, animation performance data of the model object, node relationship data, etc.

[0042] Managing the three-dimensional model mesh file data includes: configuring and modifying the file path of the three-dimensional model, and loading the file data of the three-dimensional model.

[0043] (2) The three-dimensional model material data includes: three-dimensional model material name data, material path data, shader data used by the model material, other material parameter data, etc.

[0044] Managing the three-dimensional model material data includes: configuring and modifying the main texture file, normal map file, metal map file path data, material shader data, and material color data of the material.

[0045] In some embodiments, the basic characteristic data includes: display effect data and content data. Managing the basic characteristic data includes:

[0046] Based on user requirements, respectively configure the specific content of the display effect data and the content data, customize the display interface and the display effect.

[0047] The following will introduce the specific content of the display effect data and the content data in detail respectively:

[0048] (1) The display effect data can be classified into several types: characteristic display data, text data, picture data, and animation object data, where:

[0049] 1. Characteristic button data: includes control object data of the target sub-item button, display name data of the sub-item button, hierarchical data of the sub-item button, etc.

[0050] 2. Text data: includes display content data of the text, font size data, alignment data, text box size data, display color data, display dimension data, text orientation data, object name data, object type data, coordinate data in the three-dimensional world, animation performance data, node relationship data with other objects, etc.

[0051] 3. Picture data: includes picture file path data, picture box size data, picture color data, picture dimension data, picture orientation data, picture preset data, picture object name data, picture object type data, coordinate data of the picture in the three-dimensional world, animation performance data, node relationship data between the picture and other objects, etc.

[0052] 4. Animation object data: includes name data of the object controlled by the animation, animation performance data.

[0053] (2) Content data: Taking the display effect data as the carrier, the system regards it as a part of the display effect data during configuration and parsing, such as the content data in the text data, the file path data in the picture data, etc.

[0054] In some embodiments, managing the scattered radiation data includes:

[0055] Parse the file names and file contents of the electromagnetic data and the scattered radiation data;

[0056] Draw two-dimensional curve graphs, two-dimensional color scale graphs, and three-dimensional color scale models according to the drawing principle and drawing requirements;

[0057] Add coordinate axes to the two-dimensional curve graph, two-dimensional color scale graph, and three-dimensional color scale model respectively, and perform graphic color matching, window adaptation, and window drawing.

[0058] In this embodiment, the management of scattered radiation data mainly involves parsing the file names and contents of electromagnetic data and other scattered radiation data, and performing two-dimensional and three-dimensional rendering according to the rendering principle and requirements.

[0059] Regarding step 104, the associated data after management is displayed based on user requirements.

[0060] In some embodiments, the display of the managed three-dimensional model data includes:

[0061] Parsing the material data in the built-in general three-dimensional model file in the holographic scene to generate the three-dimensional model material of the product to be displayed;

[0062] Assigning the three-dimensional model material of the product to be displayed to the three-dimensional model object of the product to be displayed;

[0063] Determining whether the three-dimensional model object of the product to be displayed is activated; if so, performing relevant operations on it based on user requirements to achieve dynamic display of the model; the relevant operations at least include moving, rotating, scaling, and highlighting.

[0064] In some embodiments, the display of the managed basic characteristic data includes: generating and assigning display effect buttons, each display effect button being used to display different contents; the display effect buttons include: characteristic display buttons, text data display buttons, picture data display buttons, and animation object data display buttons;

[0065] Clicking the corresponding button according to user needs to display the corresponding content.

[0066] In this embodiment, the basic characteristic display has dual editing display. It can not only configure and display the content of characteristic data, but also customize the display interface and display effect by configuring data and associated data to meet the display requirements of different types of basic characteristics. It is flexible and has the attributes of a tool and an engine editor. The system provides a detailed data configuration function for each effect button used to display characteristic data, and different effect buttons correspond to different data compositions.

[0067] The following details the content that each button can display:

[0068] 1. Characteristic display button: This button plays a major human-computer interaction control function, controlling the switching display and effect triggering of other characteristic display objects.

[0069] 2. Text Data Display Button: In addition to the content of the characteristic data itself, the text data also includes data such as size, position, color, and dynamic effect data required for displaying this content. After being parsed, the text data performs the text display function. This text is controlled by the configured characteristic button. After being activated, when the animation start time is reached, animations such as fade-in and typing are executed.

[0070] 3. Image Data Display Button: The preset path in the image display effect data corresponds to a rich set of built-in image display components in the system. Each target is common, but the attributes are editable. Especially for some specific combined effect diagrams, selections can be made to avoid complex editing processes. The image file path in the image data is an externally dynamically loaded image selected, which can be a display effect diagram (such as a specific effect schematic diagram) or a characteristic data diagram.

[0071] 4. Animation Object Data Display Button: All characteristic display effect data includes animation performance data, which controls the performance effect when the characteristic display effect object is initially generated. However, when the same characteristic display effect object needs to have multiple animation performances at different times, additional control is required. The animation object data records the animation performance data required for additional control. Based on the animation object data, an animation object is generated, which is specifically responsible for controlling the animation performance of other objects when a certain button is triggered or at a certain moment.

[0072] Based on the above settings, as long as the user clicks the corresponding button according to the need, the corresponding content can be displayed.

[0073] In some embodiments, the display of scattered radiation data includes:

[0074] Generating sub-buttons for the two-dimensional curve graph, two-dimensional color scale graph, and three-dimensional color scale model respectively;

[0075] Clicking the corresponding button according to the user's needs to display the corresponding content.

[0076] Finally, for step 106, based on the camera target texture rendering technology and the output form of the holographic projection device, the content to be displayed is synthesized into a holographic image and output, including:

[0077] Based on the camera target texture rendering technology, converting the images of the four sub-cameras in the camera system into texture maps;

[0078] Making the texture maps into materials and applying them to the holographic image display board composed of four triangular planes;

[0079] Based on the output form of the holographic projection device, adjusting the inclination angle of the main camera to output a holographic image using the main camera.

[0080] In this embodiment, the inclination angle of the main camera can be adjusted as needed. For example, the main camera can be adjusted to an inclination angle of 90 degrees or 45 degrees to adapt to the holographic projection device.
