[0003] Current object rendering in chess and card games involves creating separate texture coordinates for each chess piece. For example, in a mahjong game, texture coordinates must be created for each tile (e.g., one bamboo, two bamboos, one strip, two strips, etc.). Adding a new tile suit requires recreating the corresponding UVs. Modifying a model requires modifying all corresponding models, which is cumbersome and difficult to manage. Furthermore, the number of different back-face textures for different chess and card games is numerous, making management difficult. Therefore, a new object rendering method is urgently needed to efficiently handle the rendering of chess and card objects. Summary of the Invention

However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application.

[0016] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant regions, and provide corresponding operation entrances for users to choose to authorize or refuse.
[0017] First, the terms involved in one or more embodiments of the present application are explained.
[0018] Texture coordinates, often referred to as UV coordinates, are a technique used to map 2D textures onto 3D model surfaces. They are also referred to as a two-dimensional texture mapping coordinate system. Texture coordinates are used to locate pixels on the U (horizontal) and V (vertical) axes and map them to the surface of a 3D model. These coordinates are typically normalized to the range [0, 1]. This coordinate system aligns each vertex of a 3D model with a specific point on the texture image. Through interpolation, the texture is continuously distributed across the surface of the model. This system is widely used in game development, animation, and 3D rendering.
[0019] When rendering objects in online chess and card games, texture coordinates are typically set individually for each card object. If the model needs to be adjusted (e.g., adding new card flowers or adjusting the card back texture), the object model with the corresponding texture coordinates must be recreated. Furthermore, if adjustments are made to a specific object model, all object models must be modified, which is very cumbersome and hinders unified management.
[0020] Based on this, in the present application, an object rendering method is provided. The present application also relates to a computing device, a computer-readable storage medium and a computer program product, which are described in detail one by one in the following embodiments.
[0021] Figure 1 A flowchart of an object rendering method provided according to an embodiment of the present application is shown, which specifically includes the following steps: Step 102: Create an object model corresponding to the virtual object, and determine object texture coordinates corresponding to the object model.
[0022] A virtual object can be understood as a virtual image of an object to be rendered. For example, if mahjong tiles are to be rendered, the tiles are virtual objects. For another example, if playing cards are to be rendered, the playing cards are virtual objects.
[0023] The object model can be understood as the basic model corresponding to the virtual object. In computer graphics, 3D modeling, and game development, the model is the core data that describes the shape and structure of a three-dimensional object. The model is a mesh data composed of vertices, edges, and faces that describes the geometric structure of a three-dimensional object using mathematical methods.
[0024] In the specific implementations provided herein, an object model corresponding to a virtual object can be pre-created in 3D modeling software. The 3D modeling software can be Blender, 3Dmax, etc. The method provided herein does not limit the specific 3D modeling software, and the actual application shall prevail.
[0025] After creating the object model corresponding to the virtual object, determine the object texture coordinates corresponding to the object model. Object texture coordinates, also known as UV coordinates, are the core bridge for mapping 2D textures to 3D model surfaces. In UV coordinates, each vertex of the model carries the (u, v) coordinate, where u represents the horizontal coordinate and v represents the vertical coordinate. Their core function is to define the position of the model vertex on the texture.
[0026] In practical applications, each vertex of an object model independently stores corresponding UV coordinates, and the object texture coordinates corresponding to the object model can be obtained by parsing the vertex information of the object model.
[0027] Specifically, in a specific embodiment provided in this application, determining the object texture coordinates corresponding to the object model includes: The object model is parsed based on a texture editor to obtain object texture coordinates corresponding to the object model.
[0028] In practical applications, the object model can be parsed using a texture editor in 3D modeling software to obtain the object texture coordinates corresponding to the object model. For example, in Blender, you can select the UV editor in Edit mode and select each vertex of the object model to determine the object texture coordinates stored at each vertex.
[0029] In addition, a model file parsing method may be used to parse the model file of the object model using a pre-written software program to obtain the object texture coordinates corresponding to the object model.
[0030] In addition, the method provided in this application does not limit the specific implementation method of how to determine the object texture coordinates corresponding to the object model by obtaining it in the game engine, using shader debugging output, command line tool processing, etc.
[0031] Step 104: creating an object map set corresponding to the object model, wherein the object map set includes a plurality of object sub-maps, and the size of the object map set is the same as the size of the object texture coordinates.
[0032] In the method provided in this application, during the rendering process of a virtual object, a corresponding object texture set is also created for it. A texture is a 2D image wrapped around the surface of a 3D model, used to define the visual and physical properties of the model surface. An object texture set can be understood as a collection of multiple object sub-textures created for the object model.
[0033] It should be noted that in the method provided in the embodiments of this application, the object map set is presented as a single map, and the size of the object map set is the same as the size of the object texture coordinates. For example, if the object map set size is 1*1, the object texture coordinate size is also 1*1. If the number of object sub-maps in the object map set is 2*2, the UV range is adjusted to 0.5; if the number of object sub-maps in the object map set is 4*4, the model UV is reduced to 0.25.
[0034] In the specific implementations provided herein, multiple object sub-textures can be created for an object model based on actual business needs. To facilitate subsequent processing, these sub-textures are organized into an array of object texture sets. During subsequent processing, the position of an object sub-texture within the object texture set can be used for quick and accurate location, facilitating unified management of texture resources.
[0035] In a specific implementation provided in the present application, taking the object map set as a map set of mahjong pieces as an example, the object map set includes object sub-maps such as "one tube, two tubes, three tubes... one, two, three... ten thousand, twenty thousand, thirty thousand".
[0036] Step 106: adjusting the object texture coordinates according to the position information of each object sub-map in the object texture set, and sampling the texture image to be rendered corresponding to each object sub-map through the adjusted object texture coordinates.
[0037] After determining each object's sub-texture and object texture coordinates, the texture image to be rendered can be generated based on the sub-texture and object texture coordinates. The texture image to be rendered can be understood as the texture obtained by sampling the object sub-texture using the object texture coordinates and then rendering it onto the object model.
[0038] Specifically, for ease of understanding, in a specific embodiment provided in the present application, any one of the object sub-maps is used as an example for explanation. Adjusting the object texture coordinates according to the position information of each object sub-map in the object map set, and sampling the texture image to be rendered corresponding to each object sub-map using the adjusted object texture coordinates include: Determine a target object sub-map among each object sub-map; Determining target position information of the target object sub-map in the object map set; The object texture coordinates are adjusted according to the target position information.
[0039] In this embodiment, a target object sub-map is first determined among the object sub-maps. The target sub-map may be any one of the object sub-maps in the object map set.
[0040] After determining the target object sub-texture, the target position information of the target object sub-texture within the object texture set can be determined. This target position information can be understood as the location information for the target object sub-texture within the object texture set. Based on this target position information, adjustment information for the object texture coordinates can be determined, thereby adjusting the object texture coordinates so that the adjusted object texture coordinates can sample the target object sub-texture.
[0041] In another specific embodiment provided by the present application, determining target position information of the target object sub-map in the object map set includes: The target position coordinates and target size information of the target object sub-texture in the object texture set are obtained.
[0042] Accordingly, adjusting the object texture coordinates according to the target position information includes: Determining offset information of the object texture coordinates according to the target position coordinates; determining scaling information of the object texture coordinates according to the target size information; The object texture coordinates are adjusted according to the offset information and the scaling information.
[0043] In this embodiment, the target position information specifically includes the target position coordinates and target size information of the target object sub-texture in the object texture set. The target position coordinates are used to determine the location of the target object sub-texture in the object texture set, and the target size information is used to determine the size of the target object sub-texture.
[0044] After determining the target position coordinates and target size information, the offset information of the object texture coordinates is determined according to the target position coordinates, and the scaling information of the object texture coordinates is determined according to the target size information, thereby adjusting the object texture coordinates according to the offset information and the scaling information.
[0045] In the method provided in the embodiments of the present application, object rendering is achieved through a shader. Specifically, in the shader, the target position coordinates and target size information of the target object sub-map in the object map set are used. The target position coordinates and target size information are used to offset and scale the object texture coordinates accordingly, so that the object texture coordinates can be sampled into the target object sub-map, thereby obtaining a texture image to be rendered corresponding to the target object sub-map.
[0046] For example, let's assume an object map set with a size of 1*1 and 2*2 object sub-maps. The original size of the object texture coordinates is 1. When sampling the target object sub-map in the upper left corner, the target position coordinates of the target object sub-map are (0, 0) and the target size information is (0.5, 0.5). The object texture coordinates are scaled based on the target size information (0.5, 0.5), reducing the range of the object texture coordinates to 0.5. The object texture coordinates are then offset based on the target position coordinates (0, 0) of the target object sub-map so that the scaled object texture coordinates align with the target object sub-map. This allows the scaled object texture coordinates to sample the target object sub-map, resulting in the texture image to be rendered corresponding to the target object sub-map.
[0047] Step 108: Render and generate rendering objects corresponding to each object sub-map according to the to-be-rendered texture image corresponding to each object sub-map and the object model.
[0048] After obtaining the texture image to be rendered corresponding to the object sub-map, it is rendered onto the object model to obtain the rendering object corresponding to the object sub-map.
[0049] In the method provided in the embodiment of the present application, the size of the object texture coordinates is the same as the size of the object map set. The object texture coordinates are scaled and offset accordingly according to the position information of each object sub-map in the object map set, so that it can sample the texture image to be rendered corresponding to different object sub-maps. Then it is rendered into the object model to obtain the final rendering object. This processing method can use a set of resources. It only needs to use the object texture coordinates to sample different object sub-maps to switch between different rendering objects conveniently and quickly. Thereby improving the rendering efficiency. In terms of resource management convenience, it is only necessary to adjust the object sub-map in the object map set, which improves the convenience of resource management.
[0050] In actual applications, online chess and card games usually include two parts, the front and the back of the chess and card. Users can adjust the style of the chess and card by changing the color of the back. Based on this, Figure 2 FIG. 1 shows a flow chart of an object rendering method provided by another embodiment of the present application. Figure 2 As shown, the method includes: Step 202: Create an object model corresponding to the virtual object, where the object model includes a first model part and a second model part.
[0051] In practical applications, the object model is typically a three-dimensional model. Therefore, in the specific embodiments provided herein, the three-dimensional model is divided into a first model portion and a second model portion. Taking the object model as a chess and card game as an example, the first model portion can be understood as the front of the chess and card game (i.e., the different card faces in a chess and card game, such as the first and second bamboo cards in mahjong, or the two of hearts and three of spades in playing cards), and the second model portion can be understood as the back of the chess and card game (i.e., the backs of the cards in a chess and card game, which typically have the same back pattern).
[0052] In the method provided in this application, different types of card faces and card backs can be provided for users to choose from. Users can render and generate chess and card games of different styles by selecting different styles of card faces and card backs, thereby improving the user experience.
[0053] Step 204: Determine first object texture coordinates corresponding to the first model part, and second object texture coordinates corresponding to the second model part.
[0054] In this embodiment, first object texture coordinates corresponding to the first model portion and second object texture coordinates corresponding to the second model portion are determined respectively.
[0055] In practical applications, the specific implementation of determining the texture coordinates of the first object and the texture coordinates of the second object can be found in the relevant description of step 104 above, which will not be repeated here.
[0056] Step 206: Create a first object map set for the first model part, wherein the first object map set includes a plurality of first object sub-maps, and the size of the first object texture coordinates is the same as the size of the first object map set.
[0057] Step 208: Create a second object map set for the second model part, wherein the second object map set includes a plurality of second object sub-maps, and the size of the second object texture coordinates is the same as the size of the second object map set.
[0058] In this embodiment, since the object model is divided into a first model portion and a second model portion, different texture sets can be created for the first model portion and the second model portion during the creation of the texture sets. Specifically, a first object texture set is created for the first model portion, and a second object texture set is created for the second model portion. The first object texture set and the second object texture set each include multiple object sub-textures. The size of the first object texture coordinates is the same as the size of the first object texture set, and the size of the second object texture coordinates is the same as the size of the second object texture set.
[0059] Step 210: Determine a target first object sub-texture from the plurality of first object sub-textures, and determine a target second object sub-texture from the plurality of second object sub-textures.
[0060] In this embodiment, during the creation of a rendering object, corresponding rendering objects are created for the first model portion and the second model portion, respectively. Specifically, a target first object sub-map is first determined from the first object sub-map, and a target second object sub-map is determined from the plurality of second object sub-maps.
[0061] Step 212: Adjust the first object texture coordinates according to the first position information of the target first object sub-map in the first object map set, sample the target first object sub-map using the adjusted first object texture coordinates, and obtain a first texture image to be rendered.
[0062] Step 214: Adjust the second object texture coordinates according to the second position information of the target second object sub-map in the second object map set, and sample the target second object sub-map using the adjusted second object texture coordinates to obtain a second texture image to be rendered.
[0063] First adjustment information for first object texture coordinates is determined based on first position information of the first object sub-texture in the first object texture set, and the first object texture coordinates are offset and scaled based on the first adjustment information. Second adjustment information for second object texture coordinates is determined based on second position information of the second object sub-texture in the second object texture set, and the second object texture coordinates are offset and scaled based on the second adjustment information.
[0064] The first object sub-map is sampled according to the adjusted first object texture coordinates to obtain a first texture image to be rendered; and the second object sub-map is sampled according to the adjusted second object texture coordinates to obtain a second texture image to be rendered.
[0065] Step 216: Obtain a first rendering object according to the first texture image to be rendered and the first model part; obtain a second rendering object according to the second texture image to be rendered and the second model part; and obtain a rendering object according to the first rendering object and the second rendering object.
[0066] After obtaining the first texture image to be rendered, it is rendered with the first model portion to obtain a first rendering object. Similarly, a second rendering object is obtained based on the second texture image to be rendered and the second model portion.
[0067] After obtaining the first rendering object and the second rendering object, the two may be merged to generate a corresponding rendering object.
[0068] In the method provided in the embodiment of the present application, the corresponding rendering object can be rendered based on the user's selection of different types of first object sub-maps and second object sub-maps, enriching the types of rendering objects generated by the user and providing the user with more assembly and combination methods. This processing method can use a set of resources, and only needs to use the object texture coordinates to sample different object sub-maps to conveniently and quickly switch between different rendering objects. This improves rendering efficiency. In terms of resource management convenience, it is only necessary to adjust the object sub-map in the object map set, which improves the convenience of resource management.

This processing method can use a set of resources. It only needs to use the mahjong sub-texture coordinates to sample different mahjong sub-maps to switch between different rendered mahjong pieces conveniently and quickly. Thereby improving the rendering efficiency.
