[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0023] The present invention provides a scene rendering method, apparatus, computer device, and computer-readable storage medium. The scene rendering apparatus can be integrated into a computer device, which can be a server or a terminal.
[0024] The terminal may include a mobile phone, a wearable smart device, a tablet computer, a laptop computer, a personal computer (PC), and a vehicle-mounted computer.
[0025] Among them, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), as well as big data and artificial intelligence platforms.
[0026] It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
[0027] This embodiment will be described from the perspective of a scene rendering device. The scene rendering device may be integrated into a computer device, which may be a server or a terminal.
[0028] The present application provides a scene rendering method, such as Figure 1 As shown, the specific process of the scene rendering method can be as follows:
[0029] 101. Obtain a coverage weight map corresponding to the scene model. The coverage weight map is used to indicate the weights of different positions of the scene model being covered by target covering objects.
[0030] Among them, the scene model can be used to render a virtual scene in a graphical user interface. The scene may include multiple object models, and each object model is used to render an object in the virtual scene, such as a building, a tree, etc. The virtual scene is a virtual scene displayed (or provided) when the application is running on a terminal or a server. Optionally, the virtual scene is a simulation environment of the real world, or a semi-simulated and semi-fictitious virtual environment, or a purely fictitious virtual environment. The virtual scene is any one of a two-dimensional virtual scene and a three-dimensional virtual scene. The virtual environment can be the sky, land, ocean, etc., wherein the land includes environmental elements such as deserts and cities. Among them, the virtual scene is a scene with complete game logic of virtual objects such as user control. For example, for sandbox 3D shooting games, the virtual scene is a 3D game world for players to control virtual objects to fight. Example virtual scenes may include: mountains, plains, rivers, lakes, oceans, deserts, skies, plants, buildings, and at least one of vehicles. For example, for 2D card games, the virtual scene is a scene for displaying released cards or displaying virtual objects corresponding to cards. Example virtual scenes may include: an arena, a decisive battlefield, or other "field" elements or other elements that can display the status of card battles. For 2D or 3D multiplayer online tactical competitive games, the virtual scene is a 2D or 3D terrain scene for virtual objects to fight. Example virtual scenes may include: canyon-style mountains, routes, rivers, classrooms, tables and chairs, podiums and other elements.
[0031] Target coverings can include fallen leaves, fallen flowers, snowflakes, water stains, confetti, etc., which can be set according to the visual effect to be rendered. If the target covering is fallen leaves, the effect of fallen leaves on the ground or buildings in the scene can be rendered.
[0032] The coverage weight map can be used to indicate the weight of being covered by the target coverage. For example, black pixels indicate that they are not covered by the target coverage at all, white pixels indicate that they are completely covered by the target coverage, and gray pixels indicate that they are not completely covered by the target coverage.
[0033] 102. Determine an image mapping area of the target object model in the coverage weight map according to a position of the target object model included in the scene model.
[0034] The target object model can be an object in the rendered virtual scene, such as a building. If each object model in the scene model has a covering material added, the target object model can be any object model in the scene model; if only some of the object models in the scene model have a covering material added, the target object model can be the object model in the scene model that has a covering material added. If only some of the object models in the scene model have a covering material added, it is necessary to first determine the target object model from multiple object models in the scene model. That is, in one embodiment, the scene model includes multiple object models. Before the step of "determining the image mapping area of the target object model in the coverage weight map based on the position of the target object model contained in the scene model in the scene model", the scene rendering method provided in the embodiment of the present application may also include:
[0035] A target object model is determined from the plurality of object models, the model material of which includes a covering material corresponding to the target covering.
[0036] Specifically, the object model containing the covering material may be marked in advance, so as to determine the target object model from a plurality of object models based on the mark.
[0037] In one embodiment, the scene model includes multiple object models. Before the step of “determining, based on the position of a target object model included in the scene model in the scene model, an image mapping area of the target object model in the coverage weight map,” the scene rendering method provided in the embodiment of the present application may further include:
[0038] Determining the model material of each object model in the scene model;
[0039] According to the model material of each of the objects, a target object model whose model material includes a covering material corresponding to the target covering is determined from the plurality of object models.
[0040] The model material defines the visual effect of the surface of the object model, and the covering material corresponding to the target covering in the model material is used to render the visual effect of being covered by the target covering on the surface of the object model.
[0041] The target object model whose model material contains the covering material corresponding to the target covering can be determined based on the model material of each object model in the scene model. The model material of each object model in the scene model can be traversed to filter out the target object model containing the covering material from multiple object models.
[0042] Since the target cover material is added to the target object model by artists or developers during the production process of the scene model, it may be set incorrectly. Adding a cover material to an object model that does not need to be rendered to be covered by the target cover will cause the object model to incorrectly enable the effect corresponding to the cover, resulting in a waste of computer equipment performance.
[0043] According to the coverage weight map, it can be determined whether the target object model needs the coverage weight map to correspond to the scene model. According to the position of the target object model in the scene model, the image mapping area corresponding to the target object model is determined in the coverage weight map. The relative position of the target object model in the scene model can be the same as the relative position of the image mapping area in the coverage weight map.
[0044] Specifically, the relative position of the target object model in the scene model can be calculated according to the position of the target object model and the size of the scene model. For example, the center position of the target object model is (x, y), the size of the target object model is m×n, the size of the scene model is A×B, and the relative position of the center position of the target object model is The relative size of the target object model in the scene model is Assuming the size of the coverage weight map is 512×512, the center of the image mapping area is determined to be Size
[0045] The size unit of the coverage weight map is pixels, and the size unit of the scene model is physical units, such as meters, centimeters, etc.
[0046] Optionally, the image position corresponding to the scene position of the target object model may be determined based on a preset position mapping relationship, and the image mapping area may be further determined. That is, in one embodiment, the step of "determining the image mapping area of the target object model in the coverage weight map based on the position of the target object model included in the scene model in the scene model" may include:
[0047] Determining a scene position of the target object model in the scene model;
[0048] Determining an image position corresponding to the scene position according to a preset position mapping relationship between the scene model and the coverage weight map;
[0049] An image mapping area of the target object model in the coverage weight map is determined according to the image position.
[0050] Among them, the scene position is the position of the target object model in the scene model. The scene position can be a coordinate or other representation form. The target object model can have multiple scene positions, for example, it can include the positions of each model vertex of the target object model, and can also include the positions of the model vertices at the edge of the target object model in different directions, such as the positions of the model vertices at the edge in the horizontal position and the vertical position.
[0051] In one embodiment, the scene position of the target object model may include the position of a model bounding box corresponding to the target object model. Based on the position of the model bounding box, the mapped image area may be determined in the coverage weight map. That is, in one embodiment, the step of “determining the scene position of the target object model in the scene model” may include:
[0052] Determine a model bounding box corresponding to the target object model;
[0053] The scene position of the target object model in the scene is determined according to the vertex positions of the model bounding box.
[0054] Determine the model bounding box corresponding to the target object model. The model bounding box is a geometric shape that can enclose the target object model, such as a rectangle. According to the positions of the vertices of the model bounding box, that is, the vertex positions, the scene position of the target object model can be determined. For example, the vertex positions of the model bounding box can be used as the scene position of the target object model.
[0055] The image mapping area can be determined in the coverage weight map based on the scene position.
[0056] For example, the scene model and coverage weight map can be as follows Figure 2 As shown, for Figure 2 The scene model on the left and the image mapping area corresponding to the object model in the box are as follows: Figure 2 This is shown in the coverage weight graph on the right.
[0057] The preset position mapping relationship may be a calculation formula, so as to calculate the corresponding image position based on the scene position, and then determine the image mapping area; optionally, the preset position mapping relationship may also include image positions corresponding to different scene positions.
[0058] The image position corresponding to the scene position of the target object model can be determined according to the preset mapping relationship, and the image mapping area corresponding to the target object model can be determined in the coverage weight map based on the image position.
[0059] The preset position mapping relationship may be determined based on the size of the coverage weight map and the size of the scene model. That is, in one embodiment, before the step of “determining the image position corresponding to the scene position based on the preset position mapping relationship corresponding to the scene model and the coverage weight map”, the modified scene rendering method of the present application may further include:
[0060] determining a pixel size of the coverage weight map;
[0061] Determining the spatial size of the scene model;
[0062] The spatial size is converted according to the pixel size to obtain the preset position mapping relationship for indicating different scene positions in the scene model and corresponding image positions in the coverage weight map.
[0063] By determining the pixel size of the coverage weight map, determining the spatial size of the scene model, and converting the spatial size of the scene model according to the pixel size, a relationship formula for mapping the scene position to the image position can be obtained, thereby obtaining a preset position mapping relationship.
[0064] Optionally, the spatial size of the scene model can be converted into the same pixel size as the coverage weight map according to the number of pixels in the coverage weight map, and the scene position corresponding to each pixel in the coverage weight map can be determined to obtain a preset position mapping relationship.
[0065] In one embodiment, the preset position mapping relationship can be a pixel matrix, the number of rows of the pixel matrix is consistent with the number of pixels in each column of the coverage weight map, the number of columns of the pixel matrix is consistent with the number of pixels in each row of the coverage weight map, and the pixel matrix includes the scene position corresponding to each pixel. After determining the scene position, the position of the scene position in the pixel matrix can be determined. Since the size of the pixel matrix is the same as the coverage weight map, the image position corresponding to the scene position can be determined based on the position of the scene position in the pixel matrix.
[0066] Optionally, the preset position mapping relationship may record image positions corresponding to different scene positions in the form of data pairs, such as scene position-image position.
[0067] It is understood that there can be multiple scene models, and multiple scene models can constitute a larger virtual scene, namely a game map. Each scene model can be considered as a plot of land. For example, by dividing the game map, multiple plots can be obtained, and the operations of steps 101 to 104 can be performed for each scene model. If the target object model is located in more than one scene model, the image mapping area corresponding to the target object model can be determined for each scene model. That is, in one embodiment, before the step of "determining the coverage of the target covering on the target object model based on the image mapping area", the scene rendering method provided in the embodiment of the present application can also include:
[0068] If the target object model is a cross-plot model, determining adjacent plots of the scene model in the scene map;
[0069] Determine, according to the position of the target object model in the adjacent land parcel, an image mapping area of the target object model in the adjacent coverage weight map corresponding to the adjacent land parcel;
[0070] The determining, according to the image mapping area, the coverage of the target covering object on the target object model includes:
[0071] determining a first coverage condition of the target object model by the target covering object according to an image mapping area of the target object model in the coverage weight map;
[0072] determining a second coverage condition of the target object model by the target covering object according to an image mapping area of the target object model in the adjacent coverage weight map;
[0073] The coverage condition of the target object model is determined according to the first coverage condition and the second coverage condition.
[0074] If the target object model is a cross-plot model, determine the plots adjacent to the scene model (i.e., adjacent plots). Specifically, based on the plots associated with the model vertices of the target object model, determine multiple scene models containing the target object model to obtain adjacent plots, where the multiple scene models are two or more; or determine the adjacent plots of the scene model based on the connection relationship between the plots.
[0075] For each plot, the image mapping area of the target object model in the coverage weight map corresponding to the scene model is determined, that is, there are multiple corresponding image mapping areas across the plot model.
[0076] Based on multiple image mapping areas corresponding to the target object model and the plot where it is located, the coverage of the target object model is determined. Specifically, it can be a coverage weight map for each plot where the target object model is located, and the coverage of each weight coverage map for the target object model is determined to determine the overall coverage of the target object model.
[0077] 103. Determine the coverage of the target object model by the target covering according to the image mapping area.
[0078] Specifically, if the black pixels in the coverage weight map indicate that the object model is not covered by the target covering object, the coverage of the target covering object on the target object model can be determined based on the black pixels in the image mapping area. For example, if every pixel in the image mapping area is black, it is determined that the target object model is not covered by the target covering object; otherwise, it is determined that the target object model is covered by the target covering object.
[0079] Optionally, the coverage of the target cover on the target object model can also be determined based on the number or proportion of black pixels in the image mapping area. The coverage indicates whether the target object model is covered by the target cover. For example, if the number or proportion of black pixels in the image mapping area is greater than a preset threshold, it is determined that the target object model is not covered by the target cover; otherwise, it is determined that the target object model is covered by the target cover.
[0080] In one embodiment, the step of “determining the coverage of the target object model by the target covering according to the image mapping area” may include:
[0081] Determine the pixel value of the pixel point in the image mapping area;
[0082] The coverage status of the target covering object on the target object model is determined according to the pixel value and a preset condition, where the coverage status indicates whether the target object model is covered by the target covering object.
[0083] The pixel value of the pixel in the coverage weight map can range from 0 to 1. The preset condition can be that the pixel value of each pixel in the image mapping area is 0, and 0 can represent that the pixel is a black pixel. If the image mapping area is determined to meet the preset condition based on the pixel value of the pixel in the image mapping area, it is determined that the target object model is not covered by the target covering, otherwise it is determined that the target object model is covered by the target covering.
[0084] Since rendering the surface of the target object model to be covered by the target covering requires computing resources of a computer device, the preset conditions may be adjusted according to the rendering performance of the rendering terminal to adapt to the performance of the rendering terminal and improve the smoothness of the display of the rendering terminal. That is, in one embodiment, the preset conditions include a preset threshold and a preset pixel condition, and the preset threshold is determined based on the rendering performance information of the rendering terminal;
[0085] The step of “determining the coverage of the target object model by the target covering according to the pixel values and preset conditions” may include:
[0086] Determine the number of pixel points in the image mapping area whose pixel values meet a preset pixel condition;
[0087] If the number of pixels is greater than the preset threshold, it is determined that the target object model is not covered by the target covering;
[0088] If the number of pixels is not greater than the preset threshold, it is determined that the target object model is covered by the target covering.
[0089] The preset pixel condition may be that the pixel value is greater than a preset pixel threshold, or is equal to a preset pixel value, etc., which may need to be specifically set. In one example, the preset pixel condition may be that the pixel value is 0.
[0090] Determine the number of pixel points in the image mapping area whose pixel values meet the preset pixel conditions. If the number of pixel points is greater than the preset threshold, determine that the target object model is not covered by the target covering; if the number of pixel points is not greater than the preset threshold, determine that the target object model is covered by the target covering.
[0091] Among them, the preset threshold can be determined based on the rendering performance information of the rendering terminal. The better the rendering performance of the rendering terminal, the larger the preset threshold is, and the worse the rendering performance of the rendering terminal, the smaller the preset threshold is. The rendering performance information of the rendering terminal can be determined based on frame rate, rendering time, GPU load, CPU load, etc.
[0092] 104. Render the scene model based on the coverage condition to obtain a rendering result, wherein, for a target object model whose coverage condition indicates that it is not covered by the target cover, rendering is performed based on other model materials except the cover material corresponding to the target cover.
[0093] According to the coverage situation, the target object model in the scene model that is not covered by the target cover can be determined. For the target object model that is not covered by the target cover, the target object model is rendered based on the covering material except for the covering material corresponding to the target cover. For the target object model covered by the target cover, the target object model is rendered based on the covering material and other materials to obtain the rendering result of the scene model.
[0094] In one embodiment, the step of “rendering the scene model based on the coverage condition to obtain a rendering result” includes:
[0095] If the coverage condition indicates that the target object model is not covered by the target cover, turning off the cover material of the target object model;
[0096] The scene model is rendered according to the model materials that are not closed by the multiple object models to obtain a rendering result.
[0097] If the coverage situation indicates that the target object model is not covered by the target cover, the cover material of the target object model is turned off; for multiple object models in the scene model, each object model in the scene model is rendered according to the unclosed model material of each object model to obtain the rendering result of the scene model.
[0098] Optionally, for the target object model covered by the target cover, the target object model can also be rendered based on the image mapping area and the cover material corresponding to the target object model. The pixel value of each pixel in the image mapping area can indicate the weight of the cover material, so as to control the rendering of the target object model covered by the target cover based on the image mapping area.
[0099] As can be seen from the above, the embodiment of the present application obtains a coverage weight map corresponding to the scene model, where the coverage weight map is used to indicate the weights of different positions of the scene model being covered by the target cover; determines the image mapping area of the target object model in the coverage weight map according to the position of the target object model contained in the scene model in the scene model; determines the coverage of the target object model by the target cover according to the image mapping area; renders the scene model based on the coverage to obtain a rendering result, wherein, for the target object model whose coverage indicates that it is not covered by the target cover, rendering is performed based on model materials other than the cover material corresponding to the target cover. The target object model that is not covered by the target cover can be determined based on the coverage weight map, and the cover material of such target object model is turned off to avoid rendering such target object model based on the cover material, thereby reducing waste of computer resources.
