[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0035] In one embodiment of the present application, a virtual building model generation method can be run on a local terminal device or a server. When a virtual building model generation method is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0036] In a possible implementation, an embodiment of the present invention provides a method for generating a virtual building model, providing a user interface through a terminal device, wherein the terminal device can be the local terminal device mentioned above, or a client device in the cloud interaction system mentioned above.

[0037] Before explaining the virtual building model generation method provided in the embodiment of the present application, some professional terms are first introduced.

[0038] A "model" in games is a complete representation of a virtual object, be it a character, a car, or a house. These models are made up of many small three-dimensional points, called "vertices." Vertices connect to form triangles, and these triangles combine to create the object's shape. The relationship between models and vertices is like a statue composed of many small parts.

[0039] Procedural Content Generation (PCG) refers to the indirect control of generated content through logic and parameters, bypassing direct control.

[0040] Houdini: A 3D software designed entirely based on a node model. Its structure and operation methods are very different from other 3D software.

[0041] UV (texture coordinates) are used in game development to identify the position of each vertex on a model's texture map. Imagine a texture map placed on the surface of a model. UV coordinates tell the program how to map the texture map onto the model, just like applying a sticker to the surface. UV coordinates are expressed in the form of (U, V), where U represents the horizontal position and V represents the vertical position.

[0042] Figure 1 This is a flow chart of a method for generating a virtual building model provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0043] S101. Obtain at least one set of building structure parameters.

[0044] At least one set of building structure parameters includes at least: space outline parameters, structure control parameters, and placement parameters of the virtual connected entity model.

[0045] By obtaining at least one set of randomly set building structure parameters, at least one virtual building model can be generated in a subsequent step, so that the building model is more diverse.

[0046] The spatial outline parameters control the overall size of the building.

[0047] Structural control parameters control the division of the building's internal structure into several parts.

[0048] The placement parameters of the virtual connected entity model are the position and number of windows and doors.

[0049] S102. Generate a spatial geometric body using spatial contour parameters.

[0050] Using the spatial contour parameters, a spatial geometry is generated through a box to obtain a geometry with a certain size.

[0051] For example, using spatial contour parameters, a box is used to generate spatial geometry, resulting in a geometric body of defined dimensions. For PCG buildings, spatial geometry consisting of points, lines, and surfaces is used to describe the building's basic structure. In Houdini, spatial contour parameters can be used to control these points, lines, and surfaces. This can be understood as using surfaces to represent walls, and points to represent doors, windows, and so on.

[0052] S103: Using structural control parameters, structurally divide the spatial geometric body to obtain multiple spatial regions.

[0053] According to the structural control parameters, it can be determined how many parts the spatial geometry is divided into and how the spatial geometry is structurally divided.

[0054] It should be noted that in actual buildings, some spatial areas are empty areas. For example, the second floor of a building has rooms and an empty platform.

[0055] In this example, an attribute, emptyspace, is defined, representing empty space. By setting emptyspace, empty space regions can be created. For example, when emptyspaces[] = {"1_4", "2_1"} is defined, the corresponding 1-layer 4 region and 2-layer 1 region will become empty regions.

[0056] S104 : Generate a virtual segmentation entity model at a target position of a first spatial region among the multiple spatial regions to obtain a basic model of each spatial region.

[0057] The target position of the first spatial area can be a wall position, a ceiling position, or a floor position of a building. The virtual segmentation entity model is a wall, a ceiling, or a floor.

[0058] For example, the first spatial region contains the walls, ceiling, and floor. These components form the foundational framework of the entire building model. This means that the resulting foundational model for each spatial region is already sized and includes the walls, ceiling, and floor.

[0059] S105 , loading the virtual connected entity model onto a base model of a second spatial area among the multiple spatial areas according to the placement parameters of the virtual connected entity model, to obtain a virtual building model corresponding to the building structure parameters.

[0060] The second spatial area is where the virtual connected entity model can be set. By loading the virtual connected entity model onto the base model of the second spatial area among the multiple spatial areas, the resulting virtual building model includes the content of the building structure parameters, making the entire virtual building model more three-dimensional.

[0061] Thus, by randomly setting the building structure parameters, the generation efficiency of the building model is improved, the generation accuracy of the building model is improved, and models with different parameters are generated in a diversified manner, which expands the building model generation scenarios.

[0062] In summary, in this embodiment, at least one set of building structural parameters is acquired, including at least: spatial outline parameters, structural control parameters, and placement parameters of a virtual connected entity model. A spatial geometric body is generated using the spatial outline parameters. The spatial geometric body is structurally divided using the structural control parameters to obtain multiple spatial regions. A virtual segmented entity model is generated at a target location in a first spatial region among the multiple spatial regions to obtain a base model for each spatial region. Based on the placement parameters of the virtual connected entity model, the virtual connected entity model is loaded onto the base model of a second spatial region among the multiple spatial regions to obtain a virtual building model corresponding to the building structural parameters. Thus, by randomly setting the building structural parameters, the efficiency and accuracy of building model generation are improved, and models with different parameters can be generated in a diversified manner, expanding the building model generation scenarios.

[0063] In the above Figure 1 On the basis of the corresponding embodiments, the embodiments of the present application also provide a method for structural division of a spatial geometric body. Figure 2 A flowchart of a method for structural division of a spatial geometric body is also provided for the embodiment of the present application.

[0064] like Figure 2 As shown, the structural control parameters are the position parameters of the preset segmentation points. In S103, the structural control parameters are used to perform structural division on the spatial geometric body to obtain multiple spatial regions, including:

[0065] S201 : Based on position parameters of preset segmentation points, generate a plurality of segmentation surfaces passing through the preset segmentation points on a spatial geometric body.

[0066] In a three-dimensional model, if a split point is located, three split planes can be determined along the horizontal, vertical, and vertical directions of the split point. If multiple split points are located, multiple split planes can be determined along the horizontal, vertical, and vertical directions of the multiple split points.

[0067] S202. Structurally divide the spatial geometric body along multiple dividing surfaces to obtain multiple spatial regions.

[0068] Based on the position of a split point, three split planes are determined. Along the three split planes, the spatial geometric body is structurally divided to obtain eight spatial regions. Based on the positions of multiple split points, multiple split planes are determined. Along the multiple split planes, the spatial geometric body is structurally divided to obtain multiple spatial regions.

[0069] A space area can be used as a room, living room, dining room, etc.

[0070] For example, taking a South American residential building as an example, if one split point is determined, the spatial geometry is usually divided into 2*2*2, that is, three split planes are determined along the split point in the horizontal, vertical, and vertical directions, and three splits are performed. If two split points are determined, the spatial geometry is usually divided into 2*2*3, that is, four split planes are determined along the split point in the horizontal, vertical, and vertical directions, and four splits are performed.

[0071] Figure 3 This is a schematic diagram of the spatial geometric body segmentation provided in the embodiment of the present application. Figure 3 As shown, three dividing surfaces can be determined by one dividing point, thereby dividing the spatial geometry into eight spatial regions.

[0072] In summary, in this embodiment, the structural control parameters are the position parameters of the preset segmentation points. Based on the position parameters of the preset segmentation points, multiple segmentation planes passing through the preset segmentation points are generated on the spatial geometric body. The spatial geometric body is structurally divided along the multiple segmentation planes to obtain multiple spatial regions. This effectively achieves structural division of the spatial geometric body.

[0073] In the above Figure 1 On the basis of the corresponding embodiment, in another embodiment of the present application, the placement parameters of the virtual connected entity model include: the placement parameters of the internal connected entity model, and the placement parameters of the external connected entity model; the second spatial area includes: the internal spatial area, and the external spatial area.

[0074] In S105, based on the placement parameters of the virtual connected entity model, the virtual connected entity model is loaded onto the base model of the second spatial area among the multiple spatial areas to obtain a virtual building model corresponding to the building structure parameters, including:

[0075] According to the placement parameters of the internal connected entity model and the placement parameters of the external connected entity model, the internal connected entity model and the external connected entity model are loaded onto the basic models of the internal space area and the external space area to obtain the target virtual building model.

[0076] The interior space is the area of ​​the building model that has no physical contact with the exterior, such as the space between the interior walls, ceiling, and floor. This is known as a closed area. The exterior space is the area of ​​the building model that has physical contact with the exterior, such as the space outside the exterior walls. This is known as an open area. This makes the interior and exterior of the entire virtual building model appear more three-dimensional.

[0077] In summary, in this embodiment, the placement parameters of the virtual connected entity model include: placement parameters of the internal connected entity model and placement parameters of the external connected entity model; the second spatial region includes: the internal spatial region and the external spatial region; based on the placement parameters of the internal connected entity model and the placement parameters of the external connected entity model, the internal connected entity model and the external connected entity model are loaded onto the base models of the internal spatial region and the external spatial region to obtain the target virtual building model. This makes the interior and exterior of the entire virtual building model more three-dimensional.

[0078] On the basis of the above embodiment, in another embodiment of the present application, the internal connection entity model includes: a first virtual door and window and / or a virtual internal connection channel.

[0079] The external connection entity model includes: second virtual doors and windows and / or virtual external connection channels.

[0080] For example, the connecting passage is a staircase. By setting doors, windows and stairs, the entire building model is made more three-dimensional.

[0081] The model for the connecting passageway is pre-prepared, and its bounding box information is obtained. First, remove any space insufficient for the staircase. Then, find the longest edge within this space to create the staircase area. Next, hollow out the upper floor to create space for the stairs. This step is accomplished using a Boolean node. Finally, use the Copy to Point method to place the staircase at this location. At this point, a fully connected passageway is created.

[0082] In the above Figure 1 Based on the corresponding embodiments, the embodiments of the present application also provide a space merging method. Figure 4 A flow chart of a space merging method is also provided for the embodiment of the present application.

[0083] like Figure 4 As shown, the second spatial area includes: the merged spatial area. Before loading the virtual connected entity model onto the base model of the second spatial area in the multiple spatial areas according to the placement parameters of the virtual connected entity model in S105 to obtain a virtual building model corresponding to the building structure parameters, the method further includes:

[0084] S301: Determine types of multiple spatial regions according to spatial marking information of multiple spatial regions.

[0085] The spatial regions created by segmenting the spatial geometry in this way cannot meet the individual needs of different buildings. For example, some buildings require large rooms, while others have living rooms that are larger than the rooms. If the spatial regions are segmented uniformly, the need for large spaces cannot be met.

[0086] The types of spatial regions are divided into two types: merged and non-merged.

[0087] S302: Determine, based on the types of the plurality of spatial regions, whether adjacent spatial regions meet a preset region merging condition of the corresponding type.

[0088] The preset region merging conditions are: the type is merge and adjacent spatial regions are merged.

[0089] S303: If the adjacent spatial regions meet the preset region merging condition, the adjacent spatial regions are merged according to their types to obtain a merged spatial region.

[0090] By merging some spatial areas, we can obtain more diverse spatial areas and realize diversified architectural models.

[0091] For example, in Houdini software, a box node can be used to generate a larger box surrounding the two empty areas as the merged area.

[0092] For example, for the merged spatial area, by determining the heights of its vertices, the lowest surface can be separated as the bottom surface, and the floor can be generated using this surface.

[0093] In summary, in this embodiment, the second spatial region includes: a merged spatial region; determining the types of the multiple spatial regions based on the placement parameters of the virtual connected entity model and the spatial tag information of the multiple spatial regions; determining, based on the types of the multiple spatial regions, whether adjacent spatial regions meet the preset region merging conditions of the corresponding types; and, if the adjacent spatial regions meet the preset region merging conditions, merging the adjacent spatial regions based on their types to obtain a merged spatial region. Thus, by merging some spatial regions, more diverse spatial regions can be obtained, enabling the realization of diverse architectural models.

[0094] Based on the above embodiment, in another embodiment of the present application, if the external connected entity model further includes: second virtual doors and windows, it indicates that a connecting passage is formed between the building model and the external space area of ​​the building model through the second virtual doors and windows, and a virtual platform needs to be set outside the connecting passage to make the building model more three-dimensional. The method further includes:

[0095] Generate a preset virtual fence at a target position on the base model of the first external space area to form a first virtual platform corresponding to the first external space area. And / or,

[0096] A preset support entity is generated at a target position on the base model of the second external space area to form a second virtual platform corresponding to the second external space area.

[0097] The first virtual platform is a balcony, with a virtual fence set up around its edge. The second virtual platform is a courtyard, with support entities (wall columns) set up beneath the courtyard's eaves to support the eaves or the second floor of the building. This allows for more diverse architectural models.

[0098] For example, for the bottom surface of the balcony, use the bottom surface's normal direction to separate the three front-facing edges, then use the Copy to Point node in Houdini to create the fence. For the bottom surface of the courtyard, use the same operation to create the wall columns.

[0099] In summary, in this embodiment, a preset virtual fence is generated at a target location on the base model of a first external space area, forming a first virtual platform corresponding to the first external space area; and / or a preset support entity is generated at a target location on the base model of a second external space area, forming a second virtual platform corresponding to the second external space area. This allows for more diverse building models.

[0100] In the above Figure 1 On the basis of the corresponding embodiment, the embodiment of the present application also provides a wall setting method. Figure 5 A flow chart of a wall setting method is also provided for the embodiment of the present application.

[0101] like Figure 5 As shown, the virtual segmentation entity model includes: presetting a virtual wall model, generating a virtual segmentation entity model at a target position of a first spatial area in multiple spatial areas in S104, and obtaining a basic model of each spatial area, including:

[0102] S401: Generate at least one region segmentation reference line for a first spatial region.

[0103] The area division reference lines are the reference positions for placing walls.

[0104] S402: Determine at least one first reference position point on at least one region segmentation reference line.

[0105] The at least one first reference position point is used to accurately determine the placement position of the preset virtual wall model.

[0106] S403: Place the preset virtual wall model at at least one first reference position point to obtain a basic model of each spatial area.

[0107] The preset virtual wall model is determined based on width, height and orientation.

[0108] For example, in Houdini, a line with height can create a wall. Houdini has a "copyto point" node with two inputs: model A and point B. This node places model A at point B's location. Furthermore, if point B has information such as a normal and size, model A will be rotated and scaled accordingly.

[0109] For example, determine the midpoint of the region segmentation reference line and offset it slightly toward either side of the region segmentation reference line to obtain two reference points. Rays are then sent downward along each of these two reference points to determine whether they successfully intersect the entire floor surface. If both intersect successfully, the region segmentation reference line is considered an interior line. Alternatively, rays are sent upward along each of these two reference points to determine whether they successfully intersect the entire ceiling surface. If both intersect successfully, the region segmentation reference line is considered an interior line.

[0110] In summary, in this embodiment, the virtual segmentation model includes: presetting a virtual wall model; generating at least one region segmentation reference line for a first spatial region; determining at least one first reference position point on each of the at least one region segmentation reference lines; and placing the preset virtual wall model at the at least one first reference position point to obtain a base model for each spatial region. This allows for the addition of walls to a building in a variety of ways.

[0111] Based on the above embodiments, the embodiments of the present application also provide a method for setting doors and windows. Figure 6 A flow chart of a door and window setting method is also provided for the embodiment of the present application.

[0112] like Figure 6 As shown, in S403, the preset virtual wall model is placed at at least one first reference position point to obtain a basic model of each spatial area, including:

[0113] S501 : Determine a second reference position point on a regional reference line of the target wall model according to size parameters of a target wall model in each spatial region where a preset virtual wall model is placed.

[0114] The second reference position point is used to fix the preset virtual door and window model.

[0115] S502: Place the preset virtual door and window models at a second reference position point to obtain a basic model of each spatial area.

[0116] For example, a door has a set width. Based on the width of the wall, we can first lay out the possible locations for the door. In Houdini, there is a Boolean node that adds or subtracts two models. Therefore, we can use the Boolean to cut a hole in the wall the size of the door and then insert the door into it.

[0117] For example, doors in South American residential buildings are only generated at the front. Therefore, when the box space is initially generated, a 'front' feature value is added to represent the front. In this way, the front-facing edge is separated as the area with the probability of generating a door, so that these areas will generate at least one wall with a door.

[0118] Windows are placed in the same way as doors, but with slightly different placements. First, you need to set a height for the window placement. Second, windows spawn primarily on exterior walls, not interior walls.

[0119] Furthermore, for front-facing windows, window eaves are generated to make the building model more diverse.

[0120] In summary, in this embodiment, based on the dimensional parameters of the target wall model in each spatial region, where the preset virtual wall model is placed, a second reference point is determined on the regional reference line of the target wall model. Preset virtual door and window models are then placed at the second reference point to obtain a base model for each spatial region. This allows for the addition of doors and windows to buildings in a diverse manner.

[0121] In the above Figure 1 On the basis of the corresponding embodiment, in another embodiment of the present application, the architectural structure parameters further include: rendering map parameters; the method further includes:

[0122] The rendering mapping parameters are used to render the target entity model corresponding to the rendering mapping parameters on the target virtual building model.

[0123] For example, the target virtual building model is generated procedurally. After generating the target virtual building model, its rendering mapping parameters (UVs, texture coordinates, used in game development to identify the position of each vertex on the model on the texture map, with U representing horizontal position and V representing vertical position) must be processed to ensure accurate mapping and display. By projecting the UVs according to the position in world space, the correct average UVs can be obtained. In game development, walls often use four-dimensional continuous mapping. This type of mapping can be connected horizontally and vertically, making it suitable for repeated tiling on a surface.

[0124] For example, a secondary wall is rendered below the wall for decorative purposes. A decorative strip similar to a dividing line is also created between houses, simulating reality.

[0125] In summary, in this embodiment, the building structure parameters also include rendering map parameters, which are used to render the target entity model corresponding to the rendering map parameters on the target virtual building model, thereby making the building model more diverse.

[0126] Based on the above embodiment, the rendering mapping parameters include at least one mapping parameter among texture mapping parameters, material mapping parameters, and light mapping parameters.

[0127] In the above Figure 1 On the basis of the corresponding embodiment, in another embodiment of the present application, obtaining at least one set of building structure parameters in S101 includes:

[0128] According to the configuration parameters of the preset architectural style, an architectural structure parameter generation algorithm of the preset architectural style is adopted to generate at least one set of architectural structure parameters.

[0129] For example, the preset architectural style could be a South American residential style. The algorithm for generating architectural structural parameters uses the random function rand(s), where s is the random seed. By inputting the random seed, rand(s) returns a random value as the resulting random value, which is used as multiple sets of random architectural structural parameters. This allows for greater diversity in architectural models.

[0130] In summary, in this embodiment, based on the configuration parameters of a preset architectural style, an architectural structure parameter generation algorithm of the preset architectural style is used to generate at least one set of architectural structure parameters, thereby making the architectural model more diverse.

[0131] In the above Figure 1 On the basis of the corresponding embodiments, the embodiments of the present application also provide a method for generating a virtual scene. Figure 7 A flowchart of a virtual scene generation method is also provided for the embodiment of the present application.

[0132] like Figure 7 As shown, the method further includes:

[0133] S601: In response to a selection operation of a virtual building model inputted for at least one virtual building model corresponding to at least one set of building structure parameters, the target virtual building model selected by the selection operation is loaded into a preset virtual scene.

[0134] The generated virtual building model can be placed in a preset virtual scene to meet the design requirements in the virtual scene and improve design efficiency.

[0135] S602: Adjust the size of the target virtual building model in the preset virtual scene.

[0136] The target virtual building model can be adjusted according to design requirements to make the virtual scene more diverse.

[0137] In summary, in this embodiment, in response to a selection operation of a virtual building model inputted from a plurality of virtual building models corresponding to at least one set of building structure parameters, the target virtual building model selected by the selection operation is loaded into a preset virtual scene; and the target virtual building model is resized in the preset virtual scene.

[0138] The following describes a virtual building model generation device, equipment, storage medium, and program provided by the present application for execution. The specific implementation process and technical effects are described above and will not be repeated below.

[0139] Figure 8 A schematic diagram of a virtual building model generation device provided in an embodiment of the present application is shown in FIG. Figure 8 As shown, the device includes:

[0140] The acquisition module 801 is used to acquire at least one set of building structure parameters, which include at least: space outline parameters, structural control parameters, and placement parameters of the virtual connected entity model.
