Description

Technical Field

[0001] This disclosure relates to the field of computer graphics, and more specifically, to a method and apparatus for generating terrain models, a storage medium, and an electronic device. Background Technology

[0002] Currently, to make game scenes more realistic, terrain models need to be placed within them, such as ice models on rivers. Since rivers in game scenes have different shapes, the shapes of the ice models required also vary. A common approach involves pre-creating various terrain components and textures, then assembling these components to form different terrain models. This requires manually fixing the seams between components. Because each component needs to consider combination factors and properly handle seams, the entire process is cumbersome and error-prone, resulting in low efficiency in generating the overall terrain model.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0009] In at least some embodiments of this disclosure, a method is employed that generates multiple terrain components and preset texture maps of these components. Based on the regional information of a preset area in a virtual scene, a target terrain component corresponding to the terrain model is determined from the multiple terrain components. The preset texture map is then processed based on preset material parameters to obtain the target texture map. Finally, a terrain model is generated based on the target texture map and the target terrain component. This method achieves the goal of automatically adapting to different terrains based on terrain information in the game scene, saving time and effort for art staff, and achieving an ice surface art effect. This results in improved terrain model generation efficiency, enhanced terrain model generation effect, and reduced terrain model generation cost, thereby solving the technical problem of low terrain model generation efficiency.

[0023] To enable those skilled in the art to better understand the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present disclosure.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] The technical terms or technical terms appearing in the embodiments of this disclosure will be explained below:

[0026] Diffuse: Texture map.

[0027] VertexNormalWS: Vertex normals in world scene space.

[0028] Draw Call: This can be an operation where the CPU calls a command from the graphics programming interface and the GPU renders the result.

[0029] UV mapping refers to the process of transferring the 3D mesh of a 3D model to 2D space to further texture the model. UV mapping is the fundamental principle of texture creation used in all applications. UV maps are created after the polygonal 3D model is modeled and have the same mesh structure as the 3D object. However, all these polygons are converted to 2D space, so they may be deformed.

[0030] Specular: Reflectivity, used to indicate the degree of reflection of a material's surface.

[0031] roughness_factor: Roughness, used to represent the degree of surface roughness. The rougher the surface, the more obvious the light scattering.

[0032] metallic_factor: metallicity, used to indicate how many photons are directly reflected and how many photons become diffuse reflection after entering the model (if metallicity is equal to 1, it means that all photons will be reflected and there is no diffuse reflection).

[0033] In one possible implementation, addressing the persistent technical problem of low efficiency in terrain model generation, a common practice in the field of computer graphics, this disclosure focuses on the generation of terrain models in game scenes. The terrain model primarily targets ice surface models. A method for generating terrain models is proposed, employing a pre-generated terrain components of different shapes and preset texture maps. Then, based on the regional information of a preset area in the virtual scene where the terrain model is placed, the target terrain component for generating the terrain model is determined. Simultaneously, preset texture maps can be processed using preset material parameters, simplifying the workflow and sequence for art staff. The terrain module can be generated procedurally with only one creation, eliminating the need for manual seam repair. This solves the technical problem of low terrain model generation efficiency, thereby improving the generation efficiency, enhancing the generation effect, and reducing the generation cost of terrain models.

[0034] The methods and embodiments described above in this disclosure can be executed on mobile terminals, computer terminals, or similar computing devices. Taking a mobile terminal as an example, the mobile terminal can be a smartphone, tablet computer, PDA, mobile internet device, PAD, game console, or other terminal device. Figure 1 This is a hardware structure block diagram of a mobile terminal for a terrain model generation method according to an embodiment of this disclosure. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. Processor 102 (processor 102 may include, but is not limited to, a central processing unit (CPU), graphics processing unit (GPU), digital signal processing (DSP) chip, microprocessor (MCU), programmable logic device (FPGA), neural network processor (NPU), tensor processor (TPU), artificial intelligence (AI) type processor, etc.) and memory 104 for storing data. In one embodiment of this disclosure, it may also include: input / output device 108 and display device 110.

[0036] Those skilled in the art will understand that Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0037] According to one embodiment of this disclosure, an embodiment of a method for generating a terrain model is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0038] Figure 2 This is a flowchart of a method for generating a terrain model according to one embodiment of the present disclosure, such as... Figure 2 As shown, the method includes the following steps:

[0039] Step S202: Generate multiple terrain components and multiple preset texture maps of the terrain components, wherein the multiple terrain components have different shapes.

[0040] The aforementioned terrain components can be components that need to be pieced together into a terrain model and placed in the game scene. They can be components of any type of terrain, such as ice, sand dunes, rivers, lakes, etc., but are not limited to these. In this embodiment, an ice surface component is used as an example for explanation. The aforementioned preset texture map can be a pre-set texture map that can represent the material effect of ice. Different preset texture maps can be generated for different terrain components, or the same preset texture map can be generated for all terrain components.

[0041] In one optional embodiment, to simplify the workflow and sequence of the art department, the art staff can create ice block components, divided into ice block components with broken edges and irregular shapes, and regular-shaped ice block components. UV unwrapping is then performed using conventional methods to create a uniform preset texture map. Joining regular-shaped ice block components together can increase the area of ​​the ice surface model. Joining regular-shaped ice block components with broken-edge, irregular-shaped ice block components ensures that the ice surface model meets the placement requirements of the final scene. The shape effects of different ice surface models obtained by joining multiple terrain components are shown below. Figure 3 As shown.

[0042] It should be noted that, in order to ensure that regularly shaped ice cube components can be joined together, the shape of the regularly shaped ice cube components can be square, but not limited to this, and can also be triangle, hexagon, etc.

[0043] Step S204: Based on the area information of the preset area in the virtual scene, determine the target terrain component corresponding to the terrain model from multiple terrain components.

[0044] The virtual scene mentioned above can be a game scene where terrain models need to be placed. The preset area can be a specific area in the virtual scene where terrain models need to be placed. For example, an ice model needs to be placed on a river in the game scene. The area information can be information representing the location of the preset area. Since the entire ground of the game scene is made up of tiles, the area information mentioned above includes the coordinate information of multiple tiles within the preset area.

[0045] In one optional embodiment, multiple pre-made ice block components and preset texture maps can be imported into a virtual scene. A "plot vertex sorting algorithm" is then used to randomly combine the ice block components. Specifically, the algorithm calculates the edge and center plots within a preset area. Based on the edge plots, ice block components with broken edges and irregular shapes are selected, while those with regular shapes are selected based on the center plots. Finally, by combining these ice block components, the UV shape information of the ice surface model is obtained. The effect of the combined ice block model in the virtual scene is as follows: Figure 4 As shown.

[0046] Step S206: Process the preset texture map based on the preset material parameters to obtain the target texture map.

[0047] The preset material parameters mentioned above can be similar to Fresnel Effect ice surface materials, used to enhance the artistic effect. Specifically, preset material parameters can include reflectivity, roughness, and metallicity, but are not limited to these. It should be noted that the preset material parameters can be made available to users for adjustment, thereby improving the overall integrity and transparency of the ice surface model.

[0048] In one alternative embodiment, all ice block components used to generate the ice surface model can be treated as a whole and assigned a preset material parameter to achieve the ice surface material effect, such as... Figure 5a The preset material parameters shown (including the specular parameter, with a value of 0.35; the roughness_factor parameter, with a value of 1.5; and the metallic_factor parameter, with a value of 1) are used to process the preset texture map to obtain the target texture map, which is as shown below. Figure 5b The texture map shown is for a standard material effect.

[0049] Step S208: Generate a terrain model based on the target texture map and the target terrain component.

[0050] In one alternative embodiment, the target terrain components can be stitched together based on the stitching relationship between plots in a preset area to obtain an initial model, and then the target texture map can be superimposed on the initial model to obtain the final terrain model.

[0051] The method provided in the above embodiments of this disclosure generates multiple terrain components and preset texture maps of multiple terrain components. Based on the regional information of a preset area in the virtual scene, the target terrain component corresponding to the terrain model is determined from the multiple terrain components. The preset texture map is processed based on preset material parameters to obtain the target texture map. Finally, the terrain model is generated based on the target texture map and the target terrain component. This method realizes the automatic adaptation to different terrains based on terrain information in the game scene, saves the workflow and sequence of the art staff, and achieves the artistic effect of ice surface. This achieves the technical effects of improving the generation efficiency of terrain models, enhancing the generation effect of terrain models, and reducing the generation cost of terrain models, thereby solving the technical problem of low generation efficiency of terrain models.

[0052] In the above embodiments of this disclosure, the target terrain component corresponding to the terrain model is determined from multiple terrain components based on the regional information of a preset area in the virtual scene, including: determining the type of multiple plots based on the coordinate information of multiple plots using a sorting algorithm, wherein the type is used to characterize that the multiple plots are located at the edge or center of the preset area; and determining the target terrain component from multiple terrain components based on the type of multiple plots.

[0053] In one alternative embodiment, each plot has a coordinate in the virtual scene, and all plots are typically square in shape. The ice surface model needs to be placed on multiple plots, and the shapes are random and not fixed. Therefore, the coordinate information of multiple plots can be calculated using a "plot vertex sorting algorithm" to determine information such as edge plots and center plots, that is, to determine the type of each plot. The above information determines the combination method of the ice block components. Specifically, edge plots need to be placed with ice block components that are broken at the edges and have irregular shapes, while center plots need to be placed with ice block components that have regular shapes, thereby achieving a seamless splicing effect of the target terrain components in the terrain model.

[0054] In the above embodiments of this disclosure, the type of multiple land parcels is determined using a sorting algorithm based on the coordinate information of multiple land parcels, including: determining a bounding box corresponding to a preset area based on the coordinate information of multiple land parcels; comparing the target coordinate information of a target land parcel among the multiple land parcels with the bounding box to obtain a comparison result, wherein the target land parcel is any one of the multiple land parcels; in response to the comparison result that the target coordinate information is located within a first preset range in the bounding box, determining the type of the target land parcel as a first type, wherein the first preset range is used to characterize the area located at the edge of the bounding box; in response to the comparison result that the target coordinate information is located within a second preset range in the bounding box, determining the type of the target land parcel as a second type, wherein the second preset range is used to characterize other ranges in the bounding box besides the first preset range.

[0055] In one optional embodiment, the "plot vertex sorting algorithm" is implemented as follows: First, the user inputs a preset area where the ice surface model will be placed, and determines the coordinate information of all plots within that area; then, based on the plot coordinates, the maximum bounding box containing all plots is calculated, such as... Figure 4The irregular box shown; further, the coordinate information of each plot can be compared with the maximum bounding box. By the position of the coordinate information in the maximum bounding box, it can be determined whether the coordinate information is located at the edge of the maximum bounding box (i.e., within the first preset range). If it is, the plot corresponding to the coordinate information is determined to be an edge plot. If not, it indicates that the coordinate information is located at the center of the maximum bounding box (i.e., within the second preset range), and the plot corresponding to the coordinate information is determined to be a center plot. Further, based on the coordinate information of the edge plots, ice block components with broken edges and irregular shapes are placed on the edge plots, and based on the coordinate information of the center plots, ice block components with regular shapes are placed on the center plots.

[0056] In the above embodiments of this disclosure, generating a terrain model based on a target texture map and a target terrain component includes: determining a first region on the terrain model based on the target terrain component, wherein the first region is located at the edge of the terrain model; generating a target mask corresponding to the first region using a noise function; processing the target texture map based on the target mask to obtain a first texture map; and generating a terrain model based on the first texture map and the target terrain component.

[0057] To achieve better overall ice surface variation, in one optional embodiment, the shape information of the terrain model can be processed using a "salt-and-pepper noise" function to obtain an edge mask of the terrain model (i.e., the target mask mentioned above). Specifically, to make the edges of the ice surface model have a damaged-like effect, a mathematical noise function can be used to generate this shape, that is, to obtain an edge mask. Then, the edge mask is applied to the ice surface model creation process, that is, the target texture map is processed using the edge mask to obtain a first texture map, that is, a texture map with a damaged-like edge effect. Finally, the terrain model is generated based on the first texture map and the target terrain component. At this time, the terrain model not only has the effect of ice surface material, but also has a damaged-like edge effect.

[0058] Optionally, generating a target mask corresponding to the first region using a noise function includes: generating multiple first random values; sequentially connecting the multiple first random values ​​to generate a first curve; obtaining the product of the first curve and a second random value to obtain a second curve; and generating a target mask based on the second curve.

[0059] In one optional embodiment, the noise function is implemented as follows: First, several random values ​​are defined (i.e., the multiple first random values ​​mentioned above). Then, a curve function is used to connect all the random values ​​to obtain a first curve. Further, the first curve is multiplied by another random value (i.e., the second random value mentioned above), making the changes in the peaks and troughs of the second curve controllable. Finally, the target mask mentioned above can be generated. Figure 6The effect shown is a random, sharp, and damaged appearance.

[0060] In the above embodiments of this disclosure, generating a terrain model based on a target texture map and a target terrain component includes: determining a first region and a second region on the terrain model based on the target terrain component, wherein the first region is located at the edge of the terrain model, and the second region is other regions on the terrain model besides the first region; determining a first surface scattering parameter corresponding to the first region and a second surface scattering parameter corresponding to the second region; processing the target texture map based on the first surface scattering parameter and the second surface scattering parameter to obtain a second texture map; and generating a terrain model based on the second texture map and the target terrain component.

[0061] To achieve better overall ice surface variation, in one optional embodiment, a "Sub-Surface Scatterring" material scheme can be used. The user sets the first surface scattering parameters for the edge portion and the second surface scattering parameters for the center portion of the terrain model. The target texture map is then processed using these first and second surface scattering parameters to obtain a second texture map. This second texture map creates a glossy outer ring and a differentiated effect between the inner and outer sides. Finally, the second texture map and the initial model obtained by combining the target terrain components can be overlaid to obtain the terrain model. Figure 7 As shown, the edges of the terrain model exhibit a transparent effect, i.e., a light color effect, while the central area exhibits a dark color effect.

[0062] In the above embodiments of this disclosure, generating a terrain model based on a target texture map and a target terrain component includes: determining a first region and a second region on the terrain model based on the target terrain component, wherein the first region is located at the edge of the terrain model, and the second region is other regions on the terrain model besides the first region; determining a first normal curvature corresponding to the first region and a second normal curvature corresponding to the second region; processing the target texture map based on the first normal curvature and the second normal curvature to obtain a third texture map; and generating a terrain model based on the third texture map and the target terrain component.

[0063] The normal curvature mentioned above refers to the function of the point (u,v) on the surface illuminated by light and the tangent direction (du,dv) at that point. In other words, the projection of the curvature vector of the curve segment passing through the point (u,v) and tangent to the tangent direction (du,dv) onto the unit normal vector n(u,v) of the surface is exactly the normal curvature.

[0064] To achieve better overall variation of the ice surface, in one optional embodiment, the "normalcurvature" function can be used to automatically calculate the edges and apply AO (Ambient Occlusion) effects to further simulate the semi-transparent shadow effect of a real ice surface. The calculation formula for the "normalcurvature" function is as follows:

[0065]

[0066] Where L represents the direction of illumination; M represents a fixed point on the surface to be calculated; N represents the point normal of the model; E represents the edge of the tangent direction; F represents the surface of the tangent direction; G represents the intersection of the tangent directions; and I and II represent the external curvature and internal curvature of the surface.

[0067] In another alternative embodiment, the terrain model can be divided into, for example: Figure 8 The diagram shows three models: edge, corner, and center. The center model is a square, neat model, while the edge and corner models can use models with random noise shapes, such as... Figure 8 As shown, the white area represents the ice surface, and the transition from white to gray represents the color change of the ice surface at the edge.

[0068] In the above embodiments of this disclosure, generating a terrain model based on a target texture map and a target terrain component includes: sampling the target texture map multiple times to obtain multiple sampled texture maps, wherein the multiple sampled texture maps are located at different positions; overlaying the multiple sampled texture maps to obtain an overlaid texture map; and generating a terrain model based on the overlaid texture map and the target terrain component.

[0069] In one optional embodiment, to further enhance the transparency of the ice surface material and better simulate realistic lighting effects, a configurable, low-consumption parallax material can be added. This can be achieved by sampling the target texture map multiple times, with each sampling position shifted by a certain amount, and then mixing all the sampling results (after multiple stackings, the results need to be normalized) to create a pseudo-3D effect, such as... Figure 9 As shown.

[0070] It should be noted that some steps in the above scheme are only to describe the desired effect and are not limited to a specific production method. The above scheme can be produced using conventional software. For example, terrain components can be produced using Maya, Max, or Blender, and preset texture maps can be produced using Adobe Substance Panter, Adobe Substance 3D Designer, or Adobe Substance Player.

Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
