[0025] 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0027] In related technologies, rivers or lakes are typically generated in a hexagonal grid game map by splicing. This method requires artists to manually create multiple river or lake fragment models in modeling software, and then select the target river or lake fragment model to splice together. After splicing, a complete river or lake model is obtained. However, this method increases the labor cost of creating river and lake fragment models. In addition, the river or lake models generated by splicing may have insufficient precision, resulting in gaps at the splicing points of two adjacent fragment models in the complete river or lake model, affecting the quality of the game graphics.

[0028] To address the aforementioned issues, this invention provides a model generation method, apparatus, and electronic device. This technology can be applied to scenarios where water models are generated in game maps, particularly in scenarios where river or lake models are generated in game maps.

[0029] To facilitate understanding of the embodiments of the present invention, a model generation method, apparatus, and electronic device disclosed in the embodiments of the present invention will first be described in detail, such as... Figure 1 As shown, this method includes the following specific steps:

[0030] Step S102: Receive water area model generation instruction; wherein, the water area model generation instruction includes: water area type parameters and water area location of the water area model to be generated.

[0031] During game development, developers can add water models to the game map according to game rules or development needs. This means developers can send a water model generation command on the client side when adding a water model. During gameplay, players can add water models to the game map as needed, again sending a water model generation command on the game client. The water model generation command specifies the water type parameters and location of the water model to be generated. The water location indicates the position of the water model on the game map. The water type parameter indicates the type of water model to be generated, which includes at least river and lake types. When the water model to be generated is a river, the water type parameter also includes the river's flow direction.

[0032] Step S104: Based on the above water area model generation instructions, determine the target grid cell in the game map where the water area model to be generated is located; wherein, the game map is composed of multiple grid cells, and each grid cell includes multiple triangular grids.

[0033] In practical implementation, the target grid cell occupied by the water area model in the game map can be determined based on the water area location contained in the water area model generation instruction. Specifically, the game map consists of multiple grid cells, each of which is a hexagonal grid, and each grid cell includes multiple triangular grids, that is, a hexagonal grid contains multiple triangular grids.

[0034] Step S106: Adjust the mesh structure of the target mesh cell according to the water type parameters of the water model to be generated, and obtain the adjusted mesh cell.

[0035] In practice, different water area type parameters require different methods to adjust the mesh structure of the target mesh cells corresponding to the water area model to be generated, resulting in different adjusted mesh cells. The mesh structure adjustment method for each water area type parameter is pre-set and can be implemented programmatically.

[0036] Step S108: Determine the target triangular mesh where the water area model to be generated is located from the adjusted mesh cells, and assign the target triangular mesh a preset water area material to generate the water area model to be generated in the game map.

[0037] In practical implementation, different water body materials need to be set for different water body models, and the water body materials set for different locations within the same water body model also need to be different. For example, if the water body model is a river model, the material parameters of the river model need to be increased from the beginning to the end of the river to achieve the water flow effect in the water body material; if the water body model is a lake model, a water body material with a water ripple effect needs to be set in the water surface area of ​​the lake model, and in the water shore area, the material parameters need to be increased as the distance from the shore increases to achieve the white foam effect on the shore, thereby enriching the game visual presentation of the water body models in the game map.

[0038] This invention provides a model generation method. First, it receives a water model generation instruction containing water type parameters and the location of the water body to be generated. Then, based on the water model generation instruction, it determines the target grid cell containing the water body to be generated in a game map. The game map consists of multiple grid cells, each containing multiple triangular meshes. Next, according to the water type parameters of the water body to be generated, the mesh structure of the target grid cell is adjusted to obtain the adjusted grid cell. Then, the target triangular mesh containing the water body to be generated is determined from the adjusted grid cell, and a preset water material is assigned to the target triangular mesh to generate the water body model in the game map. This method can automatically generate a complete water body model by adjusting the mesh structure of the grid cells in the game map according to the water model generation instruction, thus avoiding gaps at the splicing points when obtaining a water body model through stitching, thereby improving the quality of the game graphics. At the same time, this method eliminates the need to pre-create water body segment models for splicing, thus reducing significant labor costs.

[0039] This invention also provides another model generation method, which is implemented based on the above embodiments. This method focuses on the following steps when the water body model to be generated is a river model: determining the target mesh cell in the game map based on the water body model generation command (implemented through step S204 below); adjusting the mesh structure of the target mesh cell according to the water body type parameters of the water body model to be generated, obtaining the adjusted mesh cell (implemented through steps S206-S208 below); and determining the target triangular mesh in the game map from the adjusted mesh cell, and assigning the target triangular mesh a preset water body material to the target triangular mesh (implemented through step S210 below). Figure 2 As shown, the method includes the following specific steps:

[0040] Step S202: Receive water area model generation instructions; wherein, the water area model generation instructions include: the river type, river flow direction and river location of the river model to be generated.

[0041] In practical applications, the above-mentioned water area model can be a river model. In this case, the water area type parameter of the water area model is used to indicate that the water area model is of the river type, and also to indicate the direction of river flow.

[0042] Step S204: Based on the river location of the river model, determine the target grid cell through which the river model flows in the game map.

[0043] In practice, based on the river location indicated in the water area model generation instruction, the grid cell through which the river model will flow can be determined in the game map. That is, the grid cell through which the river model flows in the game map is the target grid cell, which can be one or more.

[0044] Step S206: Add target vertices to the target grid cells according to the river flow direction of the river model.

[0045] In practice, the location of the target vertices added to the target grid cell varies depending on the river flow direction, and the number of target vertices added to the target grid cell may also differ. The method for adding target vertices for each river flow direction is pre-set, allowing the program to automatically add target vertices to the target grid cell.

[0046] In practical applications, the aforementioned grid unit is a hexagonal grid, which corresponds to a hexagonal tile in the game map. Rivers typically consist of a riverbed and a surface. Generating a riverbed requires modifying the existing land tiles in the game map (which are generated from hexagonal grids). For each hexagonal grid of a land tile, it needs to be divided outwards from the center into a central part, a transition part, and an outer part. The central part is the hexagonal region at the center of the grid, the transition part surrounds the central part, and the outer part surrounds the transition part. For example... Figure 3 The diagram shown is a schematic representation of a hexagonal grid provided in an embodiment of the present invention, wherein... Figure 3 In the diagram, the hexagonal region corresponding to 3 is the central part, the hexagonal region corresponding to 2 excluding the central part is the transition part, and the hexagonal region corresponding to 1 excluding both the central and transition parts is the outer part. This hexagonal mesh division allows for better height and material transitions. A hexagonal mesh of a plot generated using this method is shown below. Figure 4 As shown, Figure 4 The grid unit corresponding to the hexagon drawn with a set of lines is the hexagonal grid; the central part of the hexagonal grid consists of six triangular grids of equal size.

[0047] In practical implementation, when a river flows through a hexagonal mesh, the mesh structure of the hexagonal mesh needs to be modified to generate the river model. When changing the mesh structure of the hexagonal mesh, the target vertices need to be added to the hexagonal mesh according to the river flow direction in the river model. This can be achieved through the following steps 10-13:

[0048] Step 10: Based on the river flow direction of the river model, determine the first grid cell where the river begins and the second grid cell where the river ends from the target grid cell (equivalent to the hexagonal grid mentioned above), and determine the first triangular grid in the center of the first grid cell and the second triangular grid in the center of the second grid cell; the center of the grid cell consists of six triangular grids of equal size.

[0049] In specific implementations, the river flow direction mentioned above includes one of the following: the river flows through the target mesh cell in a straight line, the river flows through the target mesh cell at an acute angle, and the river flows through the target mesh cell at an obtuse angle; wherein, the preset vertex addition rule corresponding to each river flow direction is different, and each vertex addition rule is pre-set. For example... Figure 5 The diagram shown illustrates different river flow directions within a grid cell provided in an embodiment of the present invention. Figure 5 The first hexagon in the first row indicates that there is no river in the grid cell. The second hexagon in the first row indicates that the river's start and end points are within the grid cell. The first hexagon in the second row indicates that the river crosses the grid cell at an acute angle, and the second hexagon in the second row indicates that the river crosses the grid cell at an obtuse angle. The third hexagon in the third row indicates that the river crosses the grid cell in a straight line. When the river crosses the grid cell at an acute or obtuse angle, the river's inflection point is located in the center of the grid cell, and the river's start and end points are also located in the center of the grid cell.

[0050] Step 11: Add a first target vertex at the center of the edge in the first triangular mesh that flows in the same direction as the river, and add a second target vertex at the center of the edge in the second triangular mesh that flows in the opposite direction to the river.

[0051] When a target mesh cell has river inflow or outflow along a certain river flow direction, a series of vertices need to be added in the middle of the corresponding river connection area to create a concave riverbed. For the central region of the target mesh cell, the addition of target vertices needs to be determined based on the river flow direction. First, for the river's beginning and end, the first mesh cell (the starting point of the river) and the second mesh cell (the ending point of the river) need to be determined from the target mesh cells. Then, a first triangular mesh is determined in the center of the first mesh cell, and a second triangular mesh is determined in the center of the second mesh cell. The first target vertex is added in the middle of the edge corresponding to the river inflow direction (equivalent to the direction in the same direction as the river flow) in the first triangular mesh, and the second target vertex is added in the middle of the edge in the second triangular mesh corresponding to the opposite direction of the river flow.

[0052] Step 12: Based on the river flow direction and preset vertex addition rules, add a third target vertex in the center of the target grid cell other than the first and second grid cells.

[0053] In practice, different river flow directions correspond to different preset vertex addition rules, so the target vertices added to the center of the target grid cells other than the first and second grid cells are also different.

[0054] Step 13: Based on the first target vertex, the second target vertex, and the third target vertex, add multiple fourth target vertices to the transition and outer parts of the river model in the target mesh cell; wherein the height of the target vertex is lower than that of the original vertex.

[0055] like Figure 6 The diagram shown is a schematic of vertex addition when a river directly passes through a grid cell, according to an embodiment of the present invention. Figure 6 The image on the right shows the grid structure when the river flows directly through the grid cells. This grid structure is also the grid structure of the riverbed grid in the river model. Figure 6 The image on the left shows the riverbed effect formed on the game map when a river flows directly through a grid cell. Figure 6 The two dark-colored triangles represent the triangular meshes corresponding to the beginning and end of the river. The circular points added to the edges of these two triangular meshes are the first and second target vertices. The height of these first and second target vertices is lower than the original vertices in the mesh cells; this height is represented by the Z-coordinate value. After adding the first and second target vertices, the original triangles actually evolve into two triangles. It can be seen that the riverbed mesh contains parts of the river, and the mesh is denser compared to other parts. Because the added target vertices are offset towards the negative Z-coordinate (i.e., their height is lower than the original vertices), a V-shaped riverbed is formed.

[0056] For the central part of the grid cell through which the river directly passes, that is... Figure 6 For the area represented by the dark hexagon, two additional vertices need to be added on either side of the center point of the central part. The distance between these two vertices should be equal to the side length of the hexagon corresponding to the central part, which is also the width of the river. These two additional vertices, along with the original vertices of the central part, are then re-subdivided into triangles to obtain the adjusted mesh cells. Figure 6 The circular point drawn on the right side of the image, excluding the first and second target vertices, is the fourth target vertex. The fourth target vertex is on a straight line with the first and second target vertices, which is the midline of the river.

[0057] like Figure 7 The diagram shown is a schematic diagram of vertex addition when a river flows through a grid cell at an acute angle, according to an embodiment of the present invention. Figure 7 The image on the right shows the grid structure when the river flows through the grid cells at an acute angle. This grid structure is also the grid structure of the riverbed grid in the river model. Figure 7 The image on the left shows the riverbed effect formed on the game map when a river flows through grid cells at an acute angle. Figure 7 The dark hexagon in the image represents the central part of the grid cell through which the river flows at an acute angle. Three vertices need to be added below the center point of the central part; these three vertices are the third target vertices, automatically added according to preset vertex addition rules. The Z coordinates of these three vertices are offset towards the negative coordinates, and then, together with the original vertices of the central part, they are re-subdivided into triangles to obtain the adjusted grid cell. Figure 7 The fourth target vertex, which is not shown at the location where the river flows, is actually on a straight line with the vertex of the third target vertex on the edge of the central part, which is the centerline of the river.

[0058] like Figure 8 The diagram shown is a schematic diagram of vertex addition when a river flows through a grid cell at an obtuse angle, according to an embodiment of the present invention. Figure 8 The image on the right shows the grid structure when the river flows through the grid cells at an obtuse angle. This grid structure is also the grid structure of the riverbed grid in the river model. Figure 8 The image on the left shows the effect of a riverbed forming on the game map when a river flows through grid cells at an obtuse angle. Figure 8 The dark hexagons in the image represent the central part of the grid cell through which the river flows at an obtuse angle. Three vertices need to be added near the center point of this central part; these three vertices are the third target vertices, automatically added according to preset vertex addition rules. The Z coordinates of these three vertices are offset towards the negative coordinates. Then, together with the original vertices of the central part, they are re-subdivided into triangles to obtain the adjusted grid cell. Figure 8 The fourth target vertex, which is not shown at the location where the river flows, is actually on a straight line with the vertex of the third target vertex on the edge of the central part, which is the centerline of the river.

[0059] Step S208: Based on the target vertex and the original vertices in the target mesh cell, the target mesh cell is re-subdivided into triangular meshes to obtain the adjusted mesh cell.

[0060] In practical implementation, the target mesh cells can be re-triangulated based on the first, second, third, and fourth target vertices to obtain adjusted mesh cells. In the adjusted mesh cells, the triangular mesh corresponding to the area through which the river model flows is denser, and the width of the river model is equal to the side length of the hexagon corresponding to the center part of the mesh cell. Specifically, the first, second, third, and fourth target vertices need to be reconnected to the original vertices in the target mesh cells, and the target mesh cells are then re-triangulated to obtain the adjusted mesh cells.

[0061] Step S210: Determine the target triangular mesh where the river model is located from the adjusted mesh cells, and set the water area material for the target triangular mesh where the river model is located according to the preset river material setting rules, so as to obtain the river model generated in the game map.

[0062] In practical implementation, the above-mentioned river material setting rules include: setting the water area material of the river model according to the rule that the material parameters increase sequentially from the beginning to the end of the river. Specifically, the river surface part of the river model is actually just finding the corresponding vertices on both sides of the riverbed, shifting the Z coordinates of the vertices downwards to generate a facet, and then assigning the river material. The target triangular mesh corresponding to the river model needs to process UV0 so that the value of UV0.Y (equivalent to the above material parameters) increases sequentially from the beginning to the end of the river. In this way, the water flow effect can be achieved in the water area material.

[0063] The above model generation method can generate river models without additional art costs, and the generated river models are complete models without any seams. Furthermore, by writing data into the UV channels, the generated river models define data such as the river's flow direction, enabling the achievement of better river flow effects.

[0064] This invention also provides another model generation method, which is implemented based on the above embodiments. This method focuses on the following steps when the water body model to be generated is a lake model: determining the target mesh cell in the game map based on the water body model generation command (implemented through step S904 below); adjusting the mesh structure of the target mesh cell according to the water body type parameters of the water body model to be generated, obtaining the adjusted mesh cell (implemented through steps S906-S908 below); and determining the target triangular mesh where the water body model to be generated is located from the adjusted mesh cell, and assigning the target triangular mesh a preset water body material to generate the water body model in the game map (implemented through step S910 below). Figure 9 As shown, the method includes the following specific steps:

[0065] Step S902: Receive water area model generation instruction; the water area model generation instruction includes: the water area model to be generated is of the lake type, and the lake location of the lake model to be generated.

[0066] In practical applications, the above-mentioned water body model can be a lake model. In this case, the water body type parameter of the water body model is used to indicate that the type of the water body model is a lake.

[0067] Step S904: Based on the lake location of the lake model, determine the target grid cell where the lake model is located in the game map.

[0068] In practice, based on the lake location indicated in the water area model generation instructions, the target grid cell where the lake model is located can be determined in the game map. This target grid cell can be one or more.

[0069] Step S906: Determine the shore area and water surface area of ​​the lake model from the target grid cells; wherein, the shore area is the area connecting the water surface area and the shore plots.

[0070] In practice, open bodies of water like lakes will not affect the terrain mesh. As long as the water level of a grid cell is higher than the elevation, a simple water surface mesh will be generated on the plot, with a mesh structure similar to the terrain.

[0071] Step S908: Adjust the grid structure corresponding to the water surface area and the shore area in the target grid cell to obtain the adjusted grid cell.

[0072] In the actual implementation, the grid structures corresponding to the water surface area and the shore area are pre-set and can be automatically set by the program. Specifically, the lake actually consists of two parts: the water surface area in the middle, which only requires a simple hexagonal grid; and the shore area, which is the flat area connecting the water surface and the shore plots, used to create the effect of white foam on the shore.

[0073] Step S910: Determine the target triangular mesh where the lake model is located from the adjusted mesh cells, and set the water area material for the target triangular mesh where the lake model is located according to the preset lake material setting rules, so as to obtain the lake model generated in the game map.

[0074] The aforementioned lake material setting rules include: setting a water surface material with a water ripple effect in the water surface area corresponding to the target triangular mesh; and setting the water surface material in the shore area corresponding to the target triangular mesh according to the rule that the material parameter increases with distance from the shore. Specifically, the water surface area and the shore area need to be implemented separately using a fixed material. The material for the water surface area is relatively simple; a water ripple effect based on UV distortion can be created. For the shore area, UV0.Y (equivalent to the aforementioned material parameter) increases with distance from the shore, thereby achieving the effect of white foam on the shore and enriching the game's visual presentation.

[0075] like Figure 10 The image shown is a schematic diagram of a lake model provided in an embodiment of the present invention. Figure 10 The first image shows the generated effect of the lake model in the game map, the second image shows the mesh structure corresponding to the water surface area of ​​the lake model, and the third image shows the mesh structure corresponding to the shore area.

[0076] The above model generation method can generate lake models without additional art costs, and the generated lake models are complete models without any stitching gaps. Furthermore, by writing data into the UV channels, the generated lake models define data such as the distance between the lake and the shore, allowing for better white foam effects along the shore.

[0077] Corresponding to the above method embodiments, this invention also provides a model generation apparatus, such as... Figure 11 As shown, the device includes:

[0078] The instruction receiving module 90 is used to receive water area model generation instructions; wherein, the water area model generation instructions include: water area type parameters and water area location of the water area model to be generated.

[0079] The grid cell determination module 91 is used to determine the target grid cell in the game map where the water area model to be generated is located based on the water area model generation instructions; wherein, the game map is composed of multiple grid cells, and each grid cell includes multiple triangular grids.

[0080] The mesh structure adjustment module 92 is used to adjust the mesh structure of the target mesh cell according to the water type parameter of the water model to be generated, so as to obtain the adjusted mesh cell.

[0081] The material assignment module 93 is used to determine the target triangular mesh where the water model to be generated is located from the adjusted mesh cells, and to assign the target triangular mesh a preset water material to generate the water model to be generated in the game map.

[0082] The aforementioned model generation device first receives a water model generation instruction containing water type parameters and the location of the water body to be generated. Then, based on the water model generation instruction, it determines the target mesh cell containing the water body to be generated within the game map. This game map consists of multiple mesh cells, each containing multiple triangular meshes. Next, according to the water type parameters of the water body to be generated, the mesh structure of the target mesh cell is adjusted to obtain the adjusted mesh cell. Then, the target triangular mesh containing the water body to be generated is determined from the adjusted mesh cell, and a preset water material is assigned to the target triangular mesh to generate the water body model within the game map. This method can automatically generate a complete water body model by adjusting the mesh structure of the mesh cells in the game map according to the water model generation instruction, thus avoiding the gaps at the stitching points that occur when using a splicing method to obtain a water body model, thereby improving the quality of the game's visuals.
