[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] This application provides a method, apparatus, computer device, and storage medium for generating a virtual city wall model. Specifically, the method for generating a virtual city wall model can be executed by a computer device, which can be a terminal or a server. The terminal can be a smartphone, tablet, laptop, touchscreen, game console, personal computer (PC), personal digital assistant (PDA), or other terminal device. The terminal can also include a client, which can be a game application client, a browser client carrying a game program, or an instant messaging client. 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 communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0031] For example, when this method for generating a virtual city wall model runs on a terminal, the terminal device stores a game application and uses it to render a virtual scene in the game. The terminal device is used to interact with the user through a graphical user interface (GUI), such as by downloading, installing, and running the game application. The way the terminal device provides the GUI to the user can be varied; for example, it can be rendered and displayed on the terminal device's screen, or it can present the GUI through holographic projection. For instance, the terminal device can include a touchscreen display and a processor. The touchscreen display is used to present the GUI and receive user commands applied to the GUI, which includes game graphics. The processor is used to run the game, generate the GUI, respond to commands, and control the display of the GUI on the touchscreen display.

[0032] For example, when this method for generating virtual city wall models runs on a server, it can be used for cloud gaming. Cloud gaming refers to a gaming method based on cloud computing. In cloud gaming, the game application and the game screen presentation are separate. The storage and execution of the virtual city wall model generation method are completed on the cloud gaming server. The game screen presentation is completed on the cloud gaming client, which is mainly used for receiving and sending game data and presenting the game screen. For example, the cloud gaming client can be a display device with data transmission capabilities located close to the user, such as a mobile terminal, television, computer, PDA, or personal digital assistant. However, the terminal device for processing game data is the cloud gaming server in the cloud. When playing the game, the user operates the cloud gaming client to send operation commands to the cloud gaming server. The cloud gaming server runs the game according to the operation commands, encodes and compresses the game screen and other data, returns it to the cloud gaming client via the network, and finally, the cloud gaming client decodes and outputs the game screen.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of a system for generating virtual city wall models provided in an embodiment of this application. The system may include at least one terminal, at least one server, at least one database, and a network. The user's terminal can connect to different game servers via the network. The terminal is any device with computing hardware capable of supporting and executing software products corresponding to the game. Furthermore, when the system includes multiple terminals, multiple servers, and multiple networks, different terminals can connect to each other through different networks and servers. The network can be a wireless network or a wired network, such as a wireless local area network (WLAN), local area network (LAN), cellular network, 2G network, 3G network, 4G network, 5G network, etc. Additionally, different terminals can also connect to other terminals or servers using their own Bluetooth networks or hotspot networks. For example, multiple users can connect online through different terminals via appropriate networks and synchronize with each other to support multiplayer games. Furthermore, the system may include multiple databases coupled to different servers, and can continuously store information related to the game environment in the databases while different users are playing multiplayer games online.

[0034] It should be noted that, Figure 1The schematic diagram of the virtual city wall model generation system shown is merely an example. The virtual city wall model generation system and scenario described in this application embodiment are for the purpose of more clearly illustrating the technical solutions of this application embodiment and do not constitute a limitation on the technical solutions provided by this application embodiment. As those skilled in the art will know, with the emergence of new business scenarios, the technical solutions provided by this application embodiment are also applicable to similar technical problems.

[0035] The method for generating virtual city wall models provided in this application embodiment can create virtual models using 3D modeling software; then, multiple virtual models are combined to form a virtual composite model; next, the multiple virtual composite models are arranged on model arrangement lines to obtain an adjustable target virtual model. Based on this, game developers can adjust the target virtual model according to specific needs to obtain a virtual model that meets those needs, thereby quickly generating various virtual buildings, improving the reusability of virtual models, and increasing the efficiency of virtual model production.

[0036] To address the aforementioned problems, this application provides a method, apparatus, computer device, and storage medium for generating virtual city wall models, which can improve the reusability and production efficiency of virtual models. These will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0037] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for generating a virtual city wall model according to an embodiment of this application. The specific process of this method can be shown in steps 101 to 103 as follows:

[0038] 101. Obtain a virtual support model, wherein the virtual support model is used to construct a virtual city wall model.

[0039] In this embodiment of the application, the virtual support model is a virtual model, which can be created using model making software. For example, it can be created using 3D MAX (3D Studio MAX). Designers can pre-set the size and shape of the model and create a virtual model in 3D MAX based on the preset model size and shape.

[0040] The virtual model can include skinning data and bounding boxes. Skinning data can include multiple vertex data, each with corresponding weights, vertex position information, normals, triangle sequences, and other attribute information. Based on the triangle sequence of each vertex, triangular faces can be formed, and multiple triangular faces can form a graphical mesh, i.e., a triangular mesh. A bounding box is a simple geometric space containing objects of complex shapes. Adding bounding boxes to individual virtual model units serves to perform rapid collision detection or to filter collisions before performing precise collision detection; that is, precise collision detection and processing are only performed when the bounding box collides with the object.

[0041] Specifically, the virtual support model can be a virtual brick model, a virtual earth and stone model, or a virtual timber model, etc. Within the same virtual city wall model, the virtual support models of each other can have the same or different shapes. That is, the length, width, and shape of the virtual supports can be the same or different, thus making each virtual support model have a similar or different shape, making the virtual city wall model more consistent with real-life city wall architecture, and improving the realism of the virtual city wall model.

[0042] To obtain virtual support models of different shapes and forms, before the step "Obtaining Virtual Support Models", the method may include:

[0043] Obtain the first virtual cuboid model and the second virtual cuboid model;

[0044] The first virtual cuboid model is cut using the second virtual cuboid model to obtain a virtual polygon model.

[0045] For example, please see Figure 3 Artists can create a first virtual cuboid model, then randomly select a vertex from this model and move a second virtual cuboid model to that vertex's position. Next, Boolean calculations are performed on both the first and second virtual cuboid models to obtain a virtual polygon model. All parameters in this step can be randomly set, such as the length, width, and height of the first and second virtual cuboid models, and the random vertex number.

[0046] For further details, please refer to Figure 4 Artists can create a first virtual cuboid model, and then set a second virtual cuboid model on each side of the first virtual cuboid model. By using multiple second virtual cuboid models to perform Boolean calculations on the first virtual cuboid model, a more complex virtual polygon model can be obtained.

[0047] Optionally, to obtain a virtual model with a smoother surface, after the step of "cutting the first virtual cuboid model using the second virtual cuboid model to obtain a virtual polygon model", the method may include:

[0048] Each vertex of the virtual polygon model is cut to obtain a virtual support model.

[0049] For example, please see Figure 5 To make the virtual polygon model smoother and more natural, and to make its shape more organic, each vertex of the virtual polygon model can be cut. That is, a plane is used to cut off the part of the vertex at each vertex, and the part of the model corresponding to the vertex is removed, thus obtaining the virtual model.

[0050] In one specific embodiment, to expedite the generation of the virtual city wall model, after the step "obtaining the virtual support model," the method may include:

[0051] A virtual composite model is obtained by arranging multiple virtual support models sequentially along the same direction.

[0052] Furthermore, the method for the step "arranging multiple virtual support models sequentially along the same direction to obtain a virtual composite model" may include:

[0053] Obtain a preset arrangement of lines, wherein a specified number of third reference points are provided on the preset arrangement of lines;

[0054] Obtain a specified number of virtual supports, wherein all virtual supports in the specified number of virtual supports have the same width;

[0055] Based on the positions of the third reference points on the preset arrangement lines, the virtual supports of the specified number of virtual supports are arranged on the preset arrangement lines to obtain a virtual combination model.

[0056] For details, please refer to Figure 6 Artists can define a vertical line as a preset arrangement line. The number of third reference points on this preset line corresponds to the number of virtual supports set vertically. Each virtual support can then be copied to its corresponding third reference point. During the copying process, artists can also set random values ​​for some control parameters, ultimately creating five different virtual supports. Afterward, based on the height of the bounding box of each virtual support, calculations can be performed to stack all virtual supports together at zero distance, forming a vertically arranged virtual composite model.

[0057] 102. Obtain the shape trend of the virtual city wall model, wherein the shape trend is used to reflect the city wall structure of the virtual city wall model and the arrangement direction of the multiple virtual supports constituting the virtual city wall model.

[0058] Furthermore, in order to arrange and combine the virtual combination model in a regular manner, the method may include the following before the step of "obtaining the model arrangement lines":

[0059] Get custom lines;

[0060] The defined lines are divided to set multiple first reference points at specified intervals on the model arrangement lines, thereby obtaining the model arrangement lines, wherein the specified interval value is the width of the virtual model.

[0061] For details, please refer to Figure 7 Artists can randomly draw a horizontal curve in 3D modeling software as a custom line. The shape of this custom line is freely determined by the artist and serves as the shape and trend of the subsequent virtual city wall. Afterward, the artist can subdivide this custom line based on distance to set multiple first reference points at specified intervals along the model's lines. The subdivision distance is set to be approximately the length of the previously defined virtual support model.

[0062] In one specific embodiment, the method for the step "obtaining the morphological trend of the virtual city wall model, wherein the morphological trend is used to reflect the city wall structure of the virtual city wall model and the arrangement direction of the multiple virtual supports constituting the virtual city wall model" may include:

[0063] Obtain model arrangement lines, wherein the model arrangement lines represent the shape and trend of the virtual city wall, and multiple first reference points are distributed at intervals on the model arrangement lines, each first reference point being used to indicate the arrangement position of a virtual composite model on the model arrangement lines.

[0064] 103. Arrange the virtual support model along the shape and trend of the virtual city wall model to construct the virtual city wall model through the virtual support model.

[0065] To obtain a virtual city wall model with a target shape and trend, the step of "arranging the virtual support models along the shape and trend of the virtual city wall model to construct the virtual city wall model through the virtual support models" may include:

[0066] Based on the positions of the first reference points on the model arrangement lines, the virtual combination models among the multiple virtual combination models are arranged on the model arrangement lines to obtain a virtual city wall model.

[0067] In this embodiment, multiple virtual composite models can be copied to each first reference point. During the copying operation, some parameters of the virtual composite models are randomized, resulting in various "vertical rows" of different shapes. These vertical rows, when combined, form a relatively organic wall shape. For example, please refer to... Figure 8 A virtual city wall model is obtained by copying each virtual composite model from multiple virtual composite models to each first reference point.

[0068] To generate a virtual city wall model that meets the actual needs of artists, after the step "based on the setting positions of each first reference point on the model arrangement lines, arrange each virtual combination model from multiple virtual combination models on the model arrangement lines to obtain a virtual city wall model", the method may include:

[0069] In response to an adjustment command for the model arrangement lines, the adjusted setting position of each first reference point on the model arrangement lines is determined;

[0070] The virtual city wall model is updated based on the adjusted settings of each of the first reference points to obtain the updated virtual city wall model.

[0071] To add other virtual models to the virtual city wall model and make it more consistent with the shape of a real city wall, after the step "arranging the virtual combination models from multiple virtual combination models on the model arrangement lines based on the setting positions of the first reference points on the model arrangement lines to obtain the virtual city wall model", the method further includes:

[0072] In response to the instruction to set the doorway of the virtual city wall model, the virtual doorway model is obtained, and the setting position of the virtual doorway model is aligned with the target position in the shape and trend of the virtual city wall model. The virtual city wall model is then processed based on the virtual doorway model and the target position to obtain the processed virtual city wall model.

[0073] A virtual city wall model containing the virtual doorway model is generated based on the processed virtual city wall model, the virtual doorway model, and the target location.

[0074] Specifically, prior to the step "in response to the instruction to set a doorway for the virtual city wall model", the method may include:

[0075] The model arrangement lines are divided to set multiple second reference points on the model arrangement lines;

[0076] In response to the reference point determination command, a target second reference point is determined from the plurality of second reference points;

[0077] The target second reference point is taken as the target position of the trend.

[0078] Furthermore, the step "in response to the instruction to set the doorway of the virtual city wall model, obtaining the virtual doorway model, and aligning the setting position of the virtual doorway model with the target position in the shape and trend of the virtual city wall model, so as to process the virtual city wall model based on the virtual doorway model and the target position to obtain the processed virtual city wall model" can include:

[0079] In response to the instruction to set the doorway for the virtual city wall model, the virtual doorway model is obtained, and the virtual city wall model is processed based on the virtual doorway model and the target second reference point to obtain the processed virtual city wall model.

[0080] The method for generating a virtual city wall model including the virtual doorway model based on the processed virtual city wall model, the virtual doorway model, and the target location may include:

[0081] A virtual city wall model containing the virtual doorway model is generated based on the processed virtual city wall model, the virtual doorway model, and the target second reference point.

[0082] Specifically, the step "in response to the instruction to set the doorway for the virtual city wall model, obtain the virtual doorway model, and process the virtual city wall model based on the virtual doorway model and the target second reference point to obtain the processed virtual city wall model" can include:

[0083] Obtain the virtual cube model corresponding to the virtual doorway model;

[0084] Based on the setting position of the target second reference point on the model arrangement lines, the virtual cube model is used to generate doorways on the virtual city wall model to obtain the processed virtual city wall model; wherein, the center point of the model edge where the virtual doorway model coincides with the model arrangement lines coincides with the target second reference point;

[0085] The step of generating a virtual city wall model containing the virtual doorway model based on the processed virtual city wall model, the virtual doorway model, and the target second reference point includes:

[0086] Based on the setting position of the target second reference point on the model arrangement lines, the virtual doorway model is arranged on the model arrangement lines to obtain the arranged virtual doorway model;

[0087] Based on the arranged virtual doorway model and the processed virtual city wall model, a virtual city wall model containing the virtual doorway model is generated.

[0088] The virtual cube model can be a regular cube, such as a cuboid, cube, cylinder, or sphere; it can also be an irregular cube.

[0089] For example, please see Figure 9 The virtual cube model is used to generate doorways on the virtual city wall model, resulting in the processed virtual city wall model. For example, please refer to... Figure 10 The virtual doorway models are arranged on the model arrangement lines. Based on the arranged virtual doorway models and the processed virtual city wall models, a virtual city wall model containing the virtual doorway models is generated, which is the target virtual city wall model.

[0090] Specifically, artists can further subdivide the model's lines, allowing for a sufficient number of subdivisions. For example, the second reference points on the model's lines can be numbered sequentially starting from 0, used to control the movement of the virtual doorway model. Then, a cylindrical virtual model object is copied to one of the second reference points on the model's lines to create the doorway. The specific point to copy to can be determined by adjusting parameters, which control the doorway's movement along the model's lines. Next, a Boolean operation is performed between the cylindrical object and the target virtual model to create the hole. Afterward, artists can extrude the model's lines upward to form a curved surface, then perform a Boolean operation between the curved surface and the cylindrical virtual model object to obtain a line at their intersection, which is then further subdivided. Finally, a pre-defined fan-shaped virtual model is copied to the points obtained from the subdivided line to form the virtual doorway model. Finally, based on the arranged virtual doorway model and the processed target virtual model, a target virtual model for setting the doorway is generated. The target virtual model for setting the doorway is then tidied up, for example, by recalculating the surface normals and topology, to form the final shape.

[0091] To enable artists to adjust the placement of the virtual doorway model on the target virtual model according to actual needs, after the step "generating a virtual city wall model containing the virtual doorway model based on the processed virtual city wall model, the virtual doorway model, and the target second reference point," the method may include:

[0092] In response to a position adjustment command for the virtual doorway model, the adjusted position of the virtual doorway model on the model arrangement lines is determined;

[0093] The virtual city wall model containing the virtual doorway model is updated based on the adjusted position of the virtual doorway model to obtain the updated virtual city wall model.

[0094] To further illustrate the method for generating virtual city wall models provided in this application embodiment, the following will take the application of the method for generating virtual city wall models in a specific implementation scenario as an example. The specific application scenario is as follows.

[0095] (1) Artists can create a first virtual cuboid model. Then, on each edge of the first virtual cuboid model, a second virtual cuboid model is set. Boolean calculations are performed on the first virtual cuboid model using multiple second virtual cuboid models to obtain a more complex virtual polygon model. Various parameters in this step can be set randomly, such as the length, width, and height of the first virtual cuboid model, the length, width, and height of the second virtual cuboid model, and the random vertex numbers.

[0096] (2) In order to make the virtual polygon model smoother and more natural, and to make the shape more organic, each vertex of the virtual polygon model can be cut. That is, a plane is used to cut the part where the vertex is located at each vertex, and the vertex part of the model is removed to obtain the virtual model.

[0097] (3) Artists can define a vertical line as a preset arrangement line. The number of third reference points on this preset arrangement line is equal to the number of virtual models set in the vertical direction. Then, the virtual models are copied to the corresponding third reference points. During the copying operation, artists can also set random values ​​for some control parameters, ultimately forming 5 different virtual models. Afterward, based on the height of the bounding box of each virtual model, all virtual models are stacked together at zero distance to form a row of vertically arranged virtual composite models.

[0098] (4) Artists can randomly draw a curve along the horizontal direction in the 3D modeling software as a custom line. The shape of this custom line can be freely determined by the artist and will serve as the shape and trend of the subsequent virtual city wall. Afterwards, the artist can subdivide this custom line based on distance to set multiple first reference points at specified intervals on the model's line arrangement. The subdivision distance is set to be approximately the length of the previously defined virtual model.

[0099] (5) The computer device can arrange each virtual combination model among the multiple virtual combination models on the model arrangement lines based on the set positions of each first reference point on the model arrangement lines to obtain the target virtual model. Specifically, the artist copies each virtual combination model among the multiple virtual combination models to each first reference point. During the copying operation, some parameters of the virtual combination models are randomized to form various different forms of "vertical rows". These vertical rows are combined to form a relatively organic city wall shape, thus obtaining the target virtual model.

[0100] (6) When the computer device responds to the adjustment instruction for the model arrangement lines, it determines the adjusted setting position of each first reference point on the model arrangement lines; then, it updates the target virtual model based on the adjusted setting position of each first reference point to obtain the updated target virtual model.

[0101] (7) Alternatively, the artists can further subdivide the model's lines, making a sufficient number of subdivisions. For example, the second reference points on the model's lines can be numbered sequentially starting from 0, used to control the movement of the virtual doorway model. Then, a cylindrical virtual model object is copied to one of the second reference points on the model's lines to create the doorway. The artist can determine the specific second reference point by adjusting parameters, which allows control of the doorway's movement on the model's lines. Next, a Boolean operation is performed between the cylindrical object and the target virtual model to create the hole. Afterward, the artist can extrude the model's lines upward to form a curved surface, and then perform a Boolean operation between the curved surface and the cylindrical virtual model object to obtain a line at their intersection, which is then subdivided. Finally, a pre-defined fan-shaped virtual model is copied to the point obtained after subdividing the line, forming the virtual doorway model. Finally, based on the arranged virtual doorway model and the processed target virtual model, a target virtual model for setting the doorway is generated. The target virtual model for setting the doorway is then tidied up, for example, by recalculating the surface normals and topology, to form the final shape.

[0102] (8) Further, the computer device can, in response to a position adjustment command for the virtual doorway model, determine the adjusted position of the virtual doorway model on the model arrangement lines. Then, based on the adjusted position of the virtual doorway model, the target virtual model for setting the doorway is updated to obtain an updated target virtual model.

[0103] In summary, this application provides a method for generating a virtual city wall model. The method involves obtaining a virtual support model, which is used to construct the virtual city wall model. Next, the shape and trend of the virtual city wall model are obtained, reflecting the wall structure and the arrangement direction of the multiple virtual supports constituting the virtual city wall model. Finally, the virtual support models are arranged along the shape and trend of the virtual city wall model to construct the virtual city wall model. This application provides an adjustable virtual city wall model by arranging multiple virtual combination models on model arrangement lines. Game developers can adjust the virtual city wall model according to specific needs to obtain a virtual city wall model that meets their requirements. This allows for the rapid generation of various virtual city wall models, improving the reusability and production efficiency of virtual city wall models.
