[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0049] In 3D games, the user's gaming experience depends on game effects, game scenes, game rules, sound effects, and so on. Among these, the presentation of game scenes is closely related to the rendering method. A good rendering method can greatly enhance the visual effects of a game and make the most efficient use of computer computing resources.

[0050] Current high-resolution rendering techniques typically involve dividing the object into numerous triangles and then rendering it according to a sequence of vertex sequences. However, games often require rendering specific scenes containing distant terrain that doesn't require detailed rendering. Therefore, using this method in scenes where detailed rendering isn't necessary would waste computing resources and storage space.

[0051] In view of this, embodiments of the present invention provide a rendering method, the core improvement of which lies in: for special objects to be rendered that do not require fine rendering, a three-dimensional rendering model composed of rectangular rendering units is used to render them. The following description is provided through various embodiments and in conjunction with the corresponding accompanying drawings.

[0052] Please see Figure 1 , Figure 1 This is a flowchart illustrating a rendering method provided in an embodiment of the present invention, the method comprising steps S110 to S140:

[0053] Step S110: Determine the rendering unit size information based on the rendering granularity requirements of the scene to be rendered.

[0054] Step S120: Determine the 3D rendering model corresponding to the scene to be rendered based on the rendering unit size information.

[0055] It can be understood that rendering granularity corresponds to the size of the rendering unit. Accordingly, this 3D rendering model can be composed of multiple rendering units with rendering unit size information.

[0056] Step S130: Determine the set of three-dimensional coordinates corresponding to all feature vertices in the three-dimensional rendering model based on the rendering unit size information.

[0057] Feature vertices represent the vertices of a rendering unit. Since a 3D rendering model can be composed of multiple rendering units, it can correspondingly contain multiple feature vertices. In other words, in a 3D rendering model, each rendering unit contains multiple vertices, and the vertices of the rendering unit correspond to the feature vertices on the 3D rendering model.

[0058] In this embodiment, each feature vertex has its corresponding three-dimensional coordinates. The set of three-dimensional coordinates can contain the three-dimensional coordinates of all feature vertices.

[0059] Step S140: Render the 3D rendering model based on the 3D coordinate set.

[0060] It can be understood that a 3D rendering model is derived from the scene to be rendered based on the size information of the rendering units. Rendering a 3D rendering model is equivalent to rendering the scene to be rendered. The scene to be rendered can be some distant scenery in a 3D game, such as the sea, terrain, lakes, sky, etc., without limitation.

[0061] Accordingly, based on the 3D coordinate set, the 3D rendering model can be rendered with a preset color, or it can be rendered based on resource files. Resource files can contain corresponding texture files. Preset colors can be set according to actual needs and are not limited here.

[0062] This invention provides a rendering method that first determines the rendering unit size information based on the rendering granularity requirements of the scene to be rendered. Then, based on the rendering unit size information, a 3D rendering model corresponding to the scene to be rendered is determined. This 3D rendering model consists of multiple rendering units with their own size information. Next, based on the rendering unit size information, a set of 3D coordinates corresponding to all feature vertices in the 3D rendering model is determined. These feature vertices represent the vertices of the rendering units. Finally, the 3D rendering model is rendered based on the set of 3D coordinates. This method, by determining the rendering unit size information based on the rendering granularity requirements and then obtaining the 3D rendering model and its coordinate set for rendering, allows for targeted rendering according to the rendering granularity requirements of the scene, avoiding the waste of computational power caused by solely using fine-grained rendering methods.

[0063] In one possible implementation, in the 3D rendering model, the rendering unit can be a rectangle containing four vertices, where the vertices are feature vertices. The rendering granularity requirements can include the smoothness of the scene to be rendered and the required rendering precision. See also... Figure 2 , Figure 2 This is another schematic flowchart of a rendering method provided in an embodiment of the present invention. For step S110, its sub-steps include:

[0064] S110-1. Determine the rendering unit size information based on the smoothness of the scene to be rendered and the rendering accuracy requirements.

[0065] It can be understood that the rendering unit size information represents the side length information of the rendering unit. That is, when the rendering unit is a rectangle, the rendering unit size information can represent the side length information of the rectangle.

[0066] In one scenario, when the scene to be rendered is a lake in a 3D game, the rendering unit size information can meet the first preset size information because the lake is relatively flat and its rendering accuracy requirements meet the preset requirements.

[0067] In another scenario, when the scene to be rendered is a mountainous area in a 3D game, since the mountainous area has low flatness and high undulation, the rendering unit size information can meet the second preset size information if the rendering accuracy requirement meets the preset requirements.

[0068] It should be noted that the preset requirements in the above two scenarios are set according to the actual situation and are not limited here. The first preset dimension in the first preset dimension information is larger than the second preset dimension in the second preset dimension information.

[0069] Optionally, the three-dimensional coordinates consist of horizontal, vertical, and triangular coordinates. This embodiment of the invention provides a possible implementation for obtaining the horizontal, vertical, and triangular coordinates of a feature vertex. Please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a second schematic diagram of a rendering method provided in an embodiment of the present invention. For step S130, its sub-steps include:

[0070] Step S130-1: Determine the horizontal and vertical coordinates of the feature vertices based on the rendering unit size information.

[0071] It is understandable that a three-dimensional coordinate system is established with any feature vertex of the three-dimensional rendering model as the origin, and the horizontal and vertical coordinates of each feature vertex can be calculated from the rendering unit size information.

[0072] Step S130-2: Based on the horizontal and vertical coordinates of the feature vertex, determine the corresponding vertical coordinates to obtain the three-dimensional coordinates of the feature vertex.

[0073] The vertical axis coordinate can be calculated and determined from the horizontal axis coordinate and the vertical axis coordinate.

[0074] Step S130-3: Determine the three-dimensional coordinate set based on the horizontal, vertical, and axial coordinates corresponding to the feature vertices of each rendering unit.

[0075] In other words, after obtaining the horizontal, vertical, and y-axis coordinates corresponding to the feature vertices of each rendering unit, integrating them can determine the set of three-dimensional coordinates.

[0076] It can be understood that steps S130-1 to S130-3 are performed between steps S120 and S140.

[0077] Optionally, the 3D rendering model can correspond to a height function, and the 3D coordinates of each feature vertex on the 3D rendering model can be obtained from the height function. Figure 3 Based on this, embodiments of the present invention provide a possible implementation method for obtaining three-dimensional coordinates from a height function. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a third schematic diagram of another rendering method provided in an embodiment of the present invention. For step S130-2, its sub-steps include:

[0078] Step S130-2a: Obtain the height function corresponding to the 3D rendering model.

[0079] Accordingly, this height function corresponds to the scene to be rendered.

[0080] Optionally, the height function can be a binary function z = f(x, y) representing the spatial surface corresponding to the scene to be rendered, where x can represent the horizontal coordinate of the feature vertex, y can represent the vertical coordinate of the feature vertex, and z can represent the vertical coordinate of the feature vertex. This binary function z = f(x, y) can be predetermined by the spatial surface corresponding to the scene to be rendered in the actual situation, and is not limited here.

[0081] Step S130-2b: Based on the horizontal and vertical coordinates of the feature vertices, obtain the corresponding vertical coordinates using the height function to obtain the corresponding three-dimensional coordinates.

[0082] Optionally, by substituting the x-axis and y-axis coordinates of each feature vertex into the height function, the y-axis coordinates of each feature vertex can be obtained.

[0083] Optionally, the rendering of the 3D model is performed according to a rendering path sequence, which can be obtained from a set of 3D coordinates. Figure 1 Based on this, embodiments of the present invention provide a possible implementation to obtain a rendering path sequence corresponding to a set of three-dimensional coordinates. Please refer to... Figure 5 , Figure 5 This is another schematic flowchart of a rendering method provided in an embodiment of the present invention. For step S140, its sub-steps include:

[0084] Step S140-1: Remove duplicates from the three-dimensional coordinate set to obtain the vertex coordinate set.

[0085] It is understandable that when the rendering unit is rectangular, the four corresponding three-dimensional coordinates can be calculated for the four feature vertices of each rendering unit and stored in the three-dimensional coordinate set.

[0086] Accordingly, the set of 3D coordinates contains multiple duplicate 3D coordinates, which need to be deduplicated to obtain the set of vertex coordinates. This set of vertex coordinates contains the 3D coordinates of all feature vertices in the 3D rendering model.

[0087] Step S140-2: Determine the rendering path sequence based on the vertex coordinate set.

[0088] It should be noted that this rendering path sequence corresponds to the rendering order of multiple rendering units. In other words, the rendering path sequence represents the rendering order of multiple rendering units in a 3D rendering model.

[0089] Step S140-3: Render the 3D rendering model according to the rendering path sequence.

[0090] It is understandable that multiple rendering units in a 3D rendering model can be rendered in an orderly manner according to the rendering path sequence.

[0091] In one optional scenario, when a player accidentally switches screens to exit the game and then re-enters, the 3D rendering model can be rendered directly according to the rendering path sequence.

[0092] In another optional scenario, the material of each rendering unit needs to be confirmed before rendering. The material can be the color or texture corresponding to the rendering unit. Confirmation can be done in two ways:

[0093] The first method involves rendering a 3D model according to the rendering path sequence, and before rendering each rendering unit, using a confirmation function to confirm the material of that unit. This confirmation function can be a pre-defined function that confirms the material of the rendering unit.

[0094] The second approach is to divide the 3D model into multiple sub-sequences when rendering according to the rendering path sequence. Each sub-sequence corresponds to a preset number of rendering units. In this case, the 3D model is rendered sequentially according to the multiple sub-sequences, and the material of the rendering unit corresponding to each sub-sequence is confirmed before rendering each sub-sequence.

[0095] In other words, during the rendering process, material verification is performed every preset number of rendering units. In practical applications, the preset number can be set according to the actual situation, such as 5, 8, or 10. This example is merely one illustration and is not intended to be limiting.

[0096] It should be noted that the two methods of material confirmation mentioned above are merely examples and are not intended to limit the scope of the study.

[0097] Based on the rendering method described above, this embodiment of the invention also provides a rendering device 200. Please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is a functional module diagram of a rendering device provided in an embodiment of the present invention. It should be noted that its basic principle and the resulting technical effects are the same as those in the aforementioned corresponding method embodiments. For the sake of brevity, parts not mentioned in this embodiment can be referred to the corresponding content in the method embodiments. The device includes:

[0098] The processing module 210 is used to determine the rendering unit size information based on the rendering granularity requirement information corresponding to the scene to be rendered.

[0099] The processing module 210 is also used to determine the three-dimensional rendering model corresponding to the scene to be rendered based on the rendering unit size information. The three-dimensional rendering model is composed of multiple rendering units with rendering unit size information.

[0100] The processing module 210 is also used to determine the set of three-dimensional coordinates corresponding to all feature vertices in the three-dimensional rendering model based on the rendering unit size information.

[0101] Among them, feature vertices represent the vertices of the rendering unit.

[0103] Rendering module 220 is used to render the 3D rendering model based on the set of 3D coordinates.

[0104] In this embodiment, the rendering module 220 can be used to perform... Figure 1For details regarding the rendering module 220 in step S140, please refer to the previous description of step S140.

[0105] Furthermore, the rendering unit can be a rectangle containing four feature vertices, and the rendering granularity requirements can include the smoothness of the scene to be rendered and the rendering accuracy requirements.

[0106] The processing module 210 is specifically used to determine the rendering unit size information based on the smoothness of the scene to be rendered and the rendering accuracy requirements.

[0107] Among them, the rendering unit size information represents the side length information of the rendering unit.

[0108] Furthermore, the rendering of the 3D rendering model is performed according to a rendering path sequence, which can be obtained from a set of 3D coordinates.

[0109] Accordingly, the rendering module 220 is specifically used to remove duplicates from the three-dimensional coordinate set to obtain the vertex coordinate set.

[0110] The rendering module 220 is also used to determine the rendering path sequence based on the set of vertex coordinates.

[0111] The rendering module 220 is also used to render the 3D rendering model according to the rendering path sequence.

[0112] The rendering device 200 described above is used to execute the method provided in the foregoing embodiments. Its implementation principle and technical effect are similar, and will not be described again here.

[0113] These modules can be one or more integrated circuits configured to implement the above methods, such as one or more Application Specific Integrated Circuits (ASICs), one or more Digital Signal Processors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs). Alternatively, when a module is implemented using processing element scheduler code, the processing element can be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. Furthermore, these modules can be integrated together to form a System-on-a-Chip (SoC).

[0114] Furthermore, based on the rendering method described above, please refer to... Figure 7 , Figure 7This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention. The electronic device 300 includes a processor 310, a memory 320, and a bus 330. The memory 320 stores machine-readable instructions that can be executed by the processor 310. When the electronic device is running, the processor 310 and the memory 320 communicate through the bus 330. The processor 310 executes the machine-readable instructions, which implement the above-described method embodiment.

[0115] Furthermore, based on the above rendering method, this embodiment of the invention also provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the above method embodiment.

[0116] In summary, the embodiments of the present invention provide a rendering method, apparatus, electronic device, and computer-readable storage medium. First, based on the rendering granularity requirements of the scene to be rendered, the rendering unit size information is determined. Based on the rendering unit size information, a 3D rendering model corresponding to the scene to be rendered is determined. The 3D rendering model is composed of multiple rendering units with rendering unit size information. Based on the rendering unit size information, the 3D coordinate set corresponding to all feature vertices in the 3D rendering model is determined. Feature vertices represent the vertices of the rendering units. The 3D rendering model is then rendered based on the 3D coordinate set. By determining the rendering unit size information based on the rendering granularity requirements, and then further obtaining the 3D rendering model and rendering the 3D coordinate set, rendering can be performed specifically according to the rendering granularity requirements of the scene, avoiding the waste of computing power caused by solely using a fine-grained rendering method.
