[0018] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0019] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0020] The following is combined with Figures 1 to 8 , the scene rendering method, scene rendering device, electronic device and readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0021] In an embodiment of the present application, a scene rendering method is provided. Figure 1 FIG. 1 shows one of the flow charts of the scene rendering method provided in an embodiment of the present application, such as Figure 1 As shown, the scene rendering method includes:

[0022] Step 102, in response to the virtual reality scene rendering input, determining a strength range of the current network signal strength of the terminal;

[0023] Step 104 , selecting a target 3D material in the 3D material library according to the strength range of the current network signal strength; wherein the material quality of the target 3D material is associated with the strength range.

[0024] It is understandable that the higher the quality of the target 3D material, the higher the quality of the virtual reality scene rendered by the target 3D material, and the more network resources are required to transmit the target 3D material or the virtual reality scene. The lower the quality of the target 3D material, the lower the quality of the virtual reality scene rendered by the target 3D material, and the fewer network resources are required to transmit the target 3D material or the virtual reality scene.

[0025] Step 106: Display the virtual reality scene according to the target three-dimensional material.

[0026] The intensity range includes a first intensity range and a second intensity range, and the minimum value in the first intensity range is greater than the maximum value in the second intensity range, that is, the first intensity range is greater than the second intensity range.

[0027] Before displaying the virtual reality scene, it is necessary to render the virtual display scene according to the target three-dimensional material. Specifically, when the current network signal strength is within the first strength range, a rendering instruction is sent to the server, and the virtual reality scene transmitted back by the server is received;

[0028] When the current network signal strength is within the second strength range, downloading the target three-dimensional material, and rendering the virtual reality scene by using the target three-dimensional material;

[0029] The minimum value in the first intensity range is greater than the maximum value in the second intensity range.

[0030] In an embodiment of the present application, a user sends a virtual display scene rendering input to an electronic device, and the terminal sends a rendering request to the server, and the terminal detects the current network signal strength. The target three-dimensional material in the three-dimensional material library is selected according to the intensity range of the network signal strength. The three-dimensional material library in the server stores image materials and model materials, and the server can adjust the material quality of the image materials and model materials. When the network signal strength is high, it is determined that the current network speed of the terminal is fast, and the virtual reality scene can be rendered with the target three-dimensional material with high material quality. When the network signal strength is low, it is determined that the current network speed of the terminal is slow, and the virtual reality scene needs to be rendered with low-quality target three-dimensional materials.

[0031] Different rendering methods are selected according to the current network signal strength of the terminal to render the virtual reality scene. Specifically, the rendering methods include terminal rendering and cloud rendering. Among them, terminal rendering is that the terminal downloads the target 3D material to the terminal locally for rendering and display. Cloud rendering is that the server directly renders the target 3D material and transmits the rendering result back to the terminal in the form of a video stream for display.

[0032] When using cloud rendering, if the network signal strength is low, the virtual reality scene displayed on the terminal will be stuck, affecting the user's viewing experience. When using terminal rendering, the rendering time is related to the performance of the terminal. When the terminal performance is insufficient, the terminal rendering method will affect the rendering speed, resulting in low rendering efficiency, causing users to be unable to view the virtual reality scene in time.

[0033] The embodiment of the present application selects different rendering methods to render the virtual reality scene according to the current network signal strength of the terminal, thereby ensuring a high rendering effect under different network environments.

[0034] If the current network signal strength is within the first strength range, the terminal is determined to be in a strong network environment. If the current network signal strength is within the second strength range, the terminal is determined to be in a weak network environment. When the terminal is in a strong network environment, the terminal sends a rendering instruction to the server. The server models and renders the target three-dimensional material in response to the rendering instruction to obtain a virtual reality scene, and transmits the virtual reality scene back to the terminal so that the terminal displays the virtual reality scene. When the terminal is in a weak network environment, the terminal downloads the target three-dimensional material to the terminal locally, models and renders the target three-dimensional material locally, and displays the obtained virtual reality scene.

[0035] Rendering methods include cloud rendering and terminal rendering. When the terminal is in a strong network environment, the virtual reality scene is rendered through cloud rendering. Due to the strong network signal strength, the terminal is only used for the real virtual reality scene. The rendering process is executed by the server, which improves the efficiency of the terminal's real virtual reality scene. It does not need to occupy the terminal's operating resources, ensuring the smoothness and efficiency of the virtual reality scene display. When the terminal is in a weak network environment, the virtual reality scene is rendered through terminal rendering. Due to the weak network signal strength, after the terminal completes the download of the target three-dimensional material, the terminal renders the virtual reality scene locally, avoiding the problem of virtual reality scene reality freeze caused by cloud rendering in a weak network environment.

[0036] Exemplarily, when the network signal strength is within the first strength range, the target three-dimensional material of the first material quality is selected, and when the network signal strength is within the second strength range, the target three-dimensional material of the second material quality is selected. Among them, the minimum value in the first strength range is greater than the maximum value in the second strength range, and the first material quality is greater than the second material quality. When it is detected that the network signal strength is within the first strength range (the network environment is good), it is determined that the network speed of the current terminal is fast, and the target three-dimensional material of the first material quality (high quality) can be selected to render the virtual reality scene to obtain a high-quality virtual reality scene, and the high-quality virtual reality scene is displayed on the display screen of the terminal. When it is detected that the network signal is within the second strength range (the network environment is poor), it is determined that the network speed of the current terminal is slow, so the target three-dimensional material of the second material quality (low quality) is selected to render the virtual display scene.

[0037] In some embodiments, the accuracy of the virtual reality scene rendered by the server is higher than the accuracy of the virtual reality scene rendered by the terminal.

[0038] In these embodiments, the terminal is in a strong network environment, and the server obtains a virtual reality scene by rendering a high-quality target three-dimensional material. The terminal is only used to receive and display the virtual reality scene sent back by the server, which improves the clarity and fluency of the virtual reality scene. When the terminal is in a weak network environment, the server converts the high-quality target three-dimensional material into a low-quality target three-dimensional material, and the server sends the low-quality target three-dimensional material back to the terminal. The terminal obtains a virtual reality scene by rendering the low-quality target three-dimensional material, and displays a low-quality virtual reality scene, so that in a weak network environment, the terminal displays a low-quality virtual reality scene, ensuring the timeliness of the user viewing the virtual reality scene. It is worth noting that the virtual display scene can be rendered by the target three-dimensional material by the terminal, or by the server. When the terminal performs the above rendering step, it is necessary to download the target three-dimensional material to the terminal locally, render the target three-dimensional material locally, and display the rendered virtual reality scene. When the server performs the above rendering step, the server sends the rendered virtual reality scene back to the terminal so that the terminal displays the rendered virtual reality scene.

[0039] In an embodiment of the present application, before the user views the virtual reality scene, the network signal strength of the terminal is detected, and target three-dimensional materials of different material qualities are selected according to the network signal strength to render the virtual reality scene. When the terminal network environment is good, the virtual reality scene is rendered by a high-quality material model to improve the clarity and accuracy of the virtual reality scene, and when the terminal network environment is poor, the virtual reality scene is rendered by a low-quality material model, which can ensure that the user can view the virtual reality scene in time and avoid the user waiting for a long time to load the scene. The embodiment of the present application adjusts the clarity and accuracy of the rendered virtual reality scene according to the network status of the terminal, thereby improving the timeliness of the user viewing the virtual reality scene and reducing the time the user waits for the scene to load. And when the terminal is in a strong network environment, the virtual reality scene is rendered by cloud rendering, which improves the clarity and smoothness of the virtual reality scene rendering. When the terminal is in a weak network environment, the virtual reality scene is rendered by terminal rendering, which ensures the timeliness of the user viewing the virtual reality scene.

[0040] In some embodiments, when a user conducts a VR (virtual reality) house viewing, after selecting the house to be viewed, the mobile phone detects the current network signal strength. If it is detected that the mobile phone is in a weak network environment, a low-quality model request is sent to the server to select a target 3D material with lower material quality. The server sends the low-quality target 3D material to the mobile phone, and the mobile phone renders the virtual reality scene with the high-quality target 3D material and displays the virtual reality scene.

[0041] It is worth noting that a 3D material library is stored in the server, and the 3D material library includes image materials and model materials, and the image materials and model materials stored in the 3D material library are all high-quality materials. When the server receives a request for low-quality target 3D materials sent by the terminal, the server can reduce the resolution of the image materials and can also reduce the surface of the model materials, thereby generating low-quality image materials and model materials, ensuring that the low-quality image materials and model materials correspond to the high-quality image materials and model materials in the 3D material library. The low-quality virtual reality scene rendered by the terminal differs from the high-quality virtual reality scene only in clarity, ensuring that the low-quality virtual reality scene will not have distortion problems.

[0042] In some embodiments of the present application, the target three-dimensional material includes an image material and a model material. According to the strength range of the current network signal strength, the target three-dimensional material in the three-dimensional material library is selected, including:

[0043] When the current network signal strength is within a first strength range, selecting an image material with a first resolution and a model material with a first precision;

[0044] When the current network signal strength is within the second strength range, an image material with a second resolution and a model material with a second precision are selected.

[0045] The minimum value in the first intensity range is greater than the maximum value in the second intensity range, the first resolution is greater than the second resolution, and the first precision is greater than the second precision.

[0046] In the embodiment of the present application, the target three-dimensional material includes an image material and a model material. Before rendering the target three-dimensional material, the image material is set on the model material by mapping to obtain a three-dimensional model, and the three-dimensional model is rendered to obtain a virtual reality scene. Among them, the material quality of the target three-dimensional material includes the resolution of the image material and the precision of the model material. The higher the resolution of the image material, the greater the network occupancy during the transmission of the image material. The more faces of the model material and the higher the precision of the model material, the greater the network occupancy during the transmission of the model material. When the network signal strength is in different intensity ranges, image materials of different resolutions and model materials of different precisions are selected. When the minimum value in the first intensity range is greater than the maximum value in the second intensity range, and the current network signal strength is in the first intensity range, it is determined that the current network environment of the terminal is good, and when the current network signal strength is in the second intensity range, it is determined that the current network environment of the terminal is poor. When it is detected that the current network environment of the terminal is good, the image material of the first resolution (high-quality image material) and the model material of the first precision (high-quality model material) are selected. When it is detected that the current network environment of the terminal is poor, the image material of the second resolution (low-quality image material) and the model material of the second precision (low-quality model material) are selected.

[0047] In some embodiments, during the VR house viewing process, when the virtual reality scene is rendered through the terminal, if the terminal's network environment is detected to be poor, low-resolution image materials and low-precision model materials are selected, and the terminal downloads the low-resolution image materials and low-precision model materials, thereby shortening the download time. This improves the efficiency of users viewing virtual reality scenes in a weak network environment.

[0048] In some other embodiments, during the VR house viewing process, when the server is selected to render the virtual reality scene, if the terminal's network environment is detected to be poor, the server models and renders low-resolution image materials and low-precision model materials, and transmits them back to the terminal through video streaming technology, so that the terminal can realize the virtual reality scene. The video stream obtained by the server by rendering the low-quality model has a small network occupancy, and there will be no jamming during the viewing process, which improves the user's viewing experience.

[0049] The embodiment of the present application grades the network signal strength of the terminal by setting a first intensity range and a second intensity range, and sets image materials and model materials of different material qualities corresponding to the first intensity range and the second intensity range, thereby facilitating the selection of image materials and model materials according to the network signal strength of the current terminal.

[0050] In some embodiments of the present application, Figure 2 FIG. 2 shows a second flow chart of the scene rendering method provided in an embodiment of the present application. Figure 2 As shown, after rendering the virtual reality scene according to the target three-dimensional material, it also includes:

[0051] Step 202, determining the change of the current network signal strength;

[0052] Step 204: Update the virtual reality scene according to the change in the current network signal strength.

[0053] In the embodiment of the present application, the network signal strength of the terminal is continuously detected, and when it is detected that the signal strength has changed, the target three-dimensional material is reselected, and the rendered virtual reality scene is updated. Specifically, when it is detected that the terminal has changed from a weak network environment to a strong network environment, the high-quality target three-dimensional material corresponding to the low-quality virtual reality scene rendered is downloaded, and then modeling and rendering are performed using the high-quality target three-dimensional material to obtain a high-quality virtual reality scene, and the low-quality virtual reality scene is replaced with a high-quality virtual reality scene, thereby completing the update of the virtual reality scene.

[0054] In the process of rendering the virtual reality scene, the embodiment of the present application continuously detects the network signal strength of the terminal, and when the network signal strength changes, reselects the target three-dimensional material in the three-dimensional material library, and renders the virtual reality scene according to the reselected target three-dimensional material. This ensures that the terminal can display the virtual reality scene in a timely manner when the terminal is in a weak network environment, and can timely re-download high-quality target three-dimensional materials when the terminal is in a strong network environment to update the virtual reality scene.

[0055] In some embodiments of the present application, Figure 3 The third flow chart of the scene rendering method provided in the embodiment of the present application is shown as follows: Figure 3 As shown, the virtual reality scene is updated according to the change of the current network signal strength, including:

[0056] Step 302: when the current network signal strength increases from the second strength range to the first strength range, re-download the image material of the first resolution and the model material of the first precision;

[0057] Step 304: Update the virtual reality scene according to the image material with the first resolution and the model material with the first precision.

[0058] In the embodiment of the present application, it is detected that the current network signal strength increases from a lower first intensity range to a second intensity range, and it is determined that the terminal enters a strong network environment from a weak network environment. At this time, the image materials and model materials required for the virtual reality scene are re-downloaded, and the re-downloaded image materials and model materials are image materials of the first resolution (high-quality image materials) and model materials of the first precision (high-quality model materials). Modeling and rendering are performed using the image materials of the first resolution and the model materials of the first precision to obtain an updated virtual reality scene. When the terminal switches from a weak network environment to a strong network environment, the virtual reality scene can be re-modeled and rendered.

[0059] In some embodiments, when the user is viewing a house through VR, if the terminal is in a weak network environment when viewing the virtual reality scene of the initial viewpoint, the terminal will download low-resolution image materials and low-precision model materials, and set the first-resolution image materials on the first-precision model materials by mapping to obtain a three-dimensional model, and render the three-dimensional model to obtain the virtual reality scene of the initial viewpoint. When the user continues to observe the virtual reality scene of the above viewpoint, it is detected that the terminal enters a strong network environment, and the terminal re-downloads the high-resolution image materials and high-precision model materials corresponding to the viewpoint, and re-renders the virtual reality scene of the viewpoint, and switches to display the re-rendered virtual reality scene, so that the user can view the clear virtual reality scene in time.

[0060] The embodiment of the present application continuously detects the current network signal strength, and updates the low-quality virtual reality scene when the current network signal strength changes from the first strength range to the second strength range. When the user is observing the low-quality virtual reality scene, if the strength of the network signal increases, the low-quality virtual reality scene displayed on the terminal is promptly replaced with a high-quality virtual reality scene, and the clarity and accuracy of the user's viewing of the virtual reality scene is guaranteed while ensuring that the user can view the virtual reality scene in a timely manner.

[0061] In some embodiments of the present application, Figure 4 FIG. 4 shows a flow chart of a scene rendering method provided in an embodiment of the present application. Figure 4 As shown, updating the virtual reality scene according to the image material of the first resolution and the model material of the first precision includes:

[0062] Step 402, rendering the image material of the first resolution and the model material of the first precision to obtain an updated virtual reality scene, and deleting the virtual reality scene before the update;

[0063] Step 404: display the updated virtual reality scene.

[0064] In the embodiment of the present application, when it is detected that the network environment in which the terminal is located switches from a weak network environment to a strong network environment, the image material of the first resolution and the model material of the first precision are downloaded again. Then, by rendering the image material of the first resolution and the model material of the first precision, an updated virtual reality scene can be obtained, and the quality of the updated virtual reality scene is higher than the quality of the virtual reality scene before the update. At this time, the control terminal displays the updated virtual reality scene to replace the virtual reality scene before the update obtained by rendering the image material of the second resolution and the model material of the second precision, and deletes the virtual reality scene before the update.

[0065] After detecting that the network environment has changed from a weak network environment to a strong network environment, the embodiment of the present application renders the downloaded high-quality three-dimensional material to obtain an updated virtual reality scene (a high-quality virtual reality scene), and then displays the updated virtual display scene, so that the user can view the high-definition virtual reality scene as soon as possible when the network environment improves. The virtual reality scene before the update (a low-quality virtual reality scene) is deleted in time to avoid occupying the terminal memory resources for a long time.

[0066] In some embodiments of the present application, Figure 5 FIG. 5 shows a flow chart of a scene rendering method provided in an embodiment of the present application. Figure 5 As shown, determining the strength range of the current network signal strength of the terminal includes:

[0067] Step 502, timing the downloading time of the preset resource;

[0068] Among them, the preset resource can be selected as a loading map, that is, a loading map that the terminal needs to download before rendering the virtual reality scene.

[0069] Step 504: Determine the strength range of the current network signal strength of the terminal according to the download duration.

[0070] In the embodiment of the present application, before rendering the virtual reality scene, the terminal will download preset resources such as preview images from the server. The download time of the current resource downloaded by the terminal is timed, and the strength range of the current network signal strength of the terminal can be detected according to the download time of the current resource.

[0071] It is understandable that the data volume of the preset resource is a fixed value, so the current network environment of the terminal can be accurately judged according to the downloading time of downloading the preset resource.

[0072] In the embodiment of the present application, before starting to render the virtual reality scene, the terminal is controlled to download the preset resource, and the download time of the terminal downloading the preset resource is timed. The signal strength of the current network environment can be accurately determined according to the download time. While ensuring the accuracy of obtaining the current network signal strength, the step of obtaining the current network signal strength is simplified.

[0073] In some embodiments, when the terminal is downloading the target three-dimensional material from the server, or downloading the video stream of the virtual reality scene, the download duration is timed, and the change state of the current network signal strength is determined based on the download duration.

[0074] In some embodiments of the present application, determining the strength range of the current network signal strength of the terminal according to the download duration includes:

[0075] Determining that the current network signal strength is within a first strength range based on the download duration being less than a preset duration;

[0076] Based on the download duration being greater than the preset duration, it is determined that the current network signal strength is within a second strength range.

[0077] In the implementation of this application, when it is detected that the download duration is less than the preset duration, it is determined that the current network signal is strong, and the current network signal strength is determined to be in the first strength range. When it is detected that the download duration is greater than the preset duration, it is determined that the current network signal is weak, and the current network signal strength is determined to be in the second strength range.

[0078] In the implementation of the present application, by comparing the download duration with the preset duration, the strength range of the current network signal strength can be accurately determined, thereby further improving the accuracy of network signal strength detection.

[0079] The scene rendering method provided in the embodiment of the present application can be executed by a scene rendering device. In the embodiment of the present application, a method for a scene rendering device to perform model rendering is taken as an example to illustrate the scene rendering device provided in the embodiment of the present application.

[0080] In some embodiments of the present application, a scene rendering device is provided. Figure 6 The structural block diagram of the scene rendering device provided by the embodiment of the present application is shown as follows: Figure 6 As shown, the scene rendering device 600 includes:

[0081] A determination module 602 is used to determine a strength range of a current network signal strength of a terminal in response to a virtual reality scene rendering input;

[0082] A selection module 604 is used to select a target 3D material in the 3D material library according to the strength range of the current network signal strength, wherein the material quality of the target 3D material is associated with the strength range;

[0083] A sending module 606, configured to send a rendering instruction to a server when the current network signal strength is within a first strength range;

[0084] A receiving module 608 is used to receive a virtual reality scene sent back by the server, where the virtual reality scene is associated with the target three-dimensional material;

[0085] A download module 610, configured to download a target 3D material and render a virtual reality scene using the target 3D material when the current network signal strength is within a second strength range;

[0086] The rendering module 612 is used to render the virtual reality scene using the target three-dimensional material.

[0087] The minimum value in the first intensity range is greater than the maximum value in the second intensity range.

[0088] In an embodiment of the present application, before the user views the virtual reality scene, the network signal strength of the terminal is detected, and target three-dimensional materials of different material qualities are selected according to the network signal strength to render the virtual reality scene. When the terminal network environment is good, the virtual reality scene is rendered by a high-quality material model to improve the clarity and accuracy of the virtual reality scene, and when the terminal network environment is poor, the virtual reality scene is rendered by a low-quality material model, which can ensure that the user can view the virtual reality scene in time and avoid the user waiting for a long time to load the scene. The embodiment of the present application adjusts the clarity and accuracy of the rendered virtual reality scene according to the network status of the terminal, thereby improving the timeliness of the user viewing the virtual reality scene and reducing the time the user waits for the scene to load. And when the terminal is in a strong network environment, the virtual reality scene is rendered by cloud rendering, which improves the clarity and smoothness of the virtual reality scene rendering.
