Technical Field

[0002] With advancements in hardware performance and industry technology, investment in the development of open-world or large-scale games is continuously increasing. These games attract many players with their large maps, high degree of freedom, and high-precision assets. A key technical aspect of developing these games is terrain creation. Existing large-scale games require the creation of complex terrain features based on block-based models, and various automated methods for map scene creation currently exist.
[0003] In existing map scene rendering methods, masks for the corresponding blocks of terrain are first created by establishing terrain distribution rules, such as cliffs and rocks in a game scene.

[0035] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention 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 described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a 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.
[0036] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the game scene rendering method in this invention includes:
[0037] 101. Obtain the terrain data of the scene to be rendered;
[0038] It is understood that the executing entity of this invention can be a game scene rendering device, a terminal, or a server; no specific limitation is made here. This embodiment of the invention will be described using a server as an example.
[0039] In this embodiment, the scene to be rendered includes natural scenes such as mountains, plains, hills, and basins. Here, we will use mountains as an example to illustrate the scene to be rendered. For the terrain data of the mountains, we can use terrain data provided by the upstream art production team, which has a corresponding height map, including the relative height, absolute height, slope, and slope direction of the terrain structure presented in the scene to be rendered.
[0040] 102. Based on the terrain data, construct the terrain mask corresponding to the basic terrain layer simulating the terrain distribution in the scene to be rendered;
[0041] In this embodiment, based on prior knowledge, such as geological research and artistic requirements, the scene to be rendered, such as mountains, can be pre-divided into multiple geomorphic base layers according to the influence of natural environments such as climate dryness and humidity, and water erosion. For each geomorphic base layer, corresponding geomorphic distribution rules are pre-set to automatically generate geomorphic masks corresponding to each geomorphic base layer. These geomorphic distribution rules include, but are not limited to, the regional division of the geomorphic base layers and natural scene simulation. For example... Figure 2 As shown, the basic geomorphic layer can specifically include the following six items:
[0042] 1) Slope layer 201 represents the rocky slope region, which is mainly distributed on steep surfaces at high altitudes;
[0043] 2) Gravel layer 202 indicates the scree area, located at the lower part of the rocky slope where the slope is slightly steep;
[0044] 3) Flow layer 203 represents the eroded soil area, which is bare soil formed by rainwater erosion;
[0045] 4) Erosion layer 204 represents the sedimentary soil area, which is the sedimentation site on the low-altitude slope and the junction of grassland and other landform base layers.
[0046] 5) Debris layer 205 represents the dry soil area, which is a small depression where rainwater collects at low altitude;
[0047] 6) Grass layer 206 represents the grassland area, which can be other areas with gentler slopes.
[0048] This means that different types of terrain are constructed with corresponding terrain masks, without the need to construct each block individually. For blocks of the same terrain type, such as generating 5 gravel blocks in the scene to be constructed, the existing method constructs 5 gravel blocks separately, while by using terrain distribution rules, it is only necessary to define the area of the Gravel layer and then perform natural scene simulation to generate the required 5 gravel blocks.
[0049] The scene to be rendered may include one or more terrain base layers. When there are multiple terrain base layers, the terrain mask corresponding to each terrain base layer can be built independently or according to a pre-set association rule. At the same time, the terrain mask corresponding to each terrain base layer can be built sequentially in a preset order, or the terrain mask corresponding to each terrain base layer can be built separately and then stitched together.
[0050] When constructing the geomorphic base layer according to the geomorphic distribution rules, if there are multiple geomorphic base layers with overlapping parts, the following methods can be used: the later-generated geomorphic base layer covers the earlier-generated geomorphic base layer; the earlier-generated geomorphic base layer covers the later-generated geomorphic base layer; or a transitional method can be used. No specific restrictions are imposed here.
[0051] 103. Based on the terrain mask, perform material mixing on the basic terrain layer to obtain the corresponding terrain scene.
[0052] In this embodiment, the material rendering rules for each terrain base layer are pre-set and applied to the material shader. After the terrain mask corresponding to one or more terrain base layers is constructed, it is imported into the corresponding shader. The material rendering rules are used to perform layer blending on the corresponding terrain base layer to generate the terrain scene with the expected material effect.
[0053] The generation of terrain masks and the use of terrain masks for material blending of the terrain base layer can be handled separately. For example, terrain masks can be constructed using DCC (Digital Content Creation) tools such as Houdini and stored as data packages for later use. Then, when a terrain scene needs to be generated, the data package corresponding to the terrain mask can be imported into the game engine for material blending to generate the corresponding terrain scene.
[0054] In this embodiment of the invention, terrain data of the scene to be rendered is acquired; then, a terrain mask corresponding to the basic terrain layer in the scene to be rendered is constructed according to a preset terrain distribution rule, so that the terrain mask of each block in the scene to be rendered is uniformly constructed according to different types; finally, the corresponding terrain base layer can be mixed with materials according to the terrain mask to obtain the corresponding terrain scene. By using terrain distribution rules to replace block construction for terrain mask construction, the uniform construction of blocks of the same type in the game terrain scene is realized, thereby reducing the requirements for hardware performance and reducing the amount of resources required, thus improving the efficiency of game scene production, making large game terrain scenes suitable for mobile devices and easy to debug according to terrain distribution rules.
[0055] Specifically, the following embodiments provide two methods for edge optimization processing of the basic terrain layer:
[0056] In one implementation, when performing material blending on the terrain base layer, the border area between the terrain base layers can be determined based on the terrain mask, and the blending value between the pixel normal and vertex normal in the terrain base layer can be calculated based on the border area; based on the blending value, the terrain base layer is spatially offset, and the corresponding border area after the spatially offset is material blended to obtain the corresponding terrain scene.
[0057] In this embodiment, the masking data can determine the area of each terrain base layer, which can be represented by (0,1). In a terrain base layer, "1" represents the area occupied by that terrain base layer. Therefore, through the masking data corresponding to each terrain base layer, the border area between each terrain base layer can be determined. The masking data can determine the pixel normal and vertex normal. Then, based on the blending value of the two, a spatial angular offset is made to the terrain base layer, preferably in the Z direction, so that there is a more natural transition effect after the overlapping material of two terrain base layers is blended.
[0058] Specifically, if the Slope layer is adjacent to the Erosion layer, the angle of the Slope layer's material layer can be offset according to the Z-axis of the Pixel Normal and Vertex Normal blending values. In the Shader, the Erosion layer material and the Slope layer material are blended once to create a more natural transition effect.
[0059] In one implementation, after constructing the terrain mask corresponding to each terrain base layer, the edge information of each terrain mask can be determined, and each terrain mask can be used as a negative area in sequence; based on the negative area, edge noise can be added to each terrain mask in sequence to obtain a new terrain mask.
[0060] In this embodiment, since reading Pixel Normal can affect hardware performance, such as increasing resource consumption when used on mobile devices, optimization for terrain masking is further proposed. The edges of the terrain mask are processed to reduce hardware performance requirements while also optimizing the edges. For example, edge noise is added after creating the terrain mask in Houdini to achieve a more natural transition effect.
[0061] Specifically, taking the Gravel layer as an example, based on the actual mixing situation, if Gravel is considered the negative form and the adjacent terrain base layer is the Grass layer, then the Grass layer is considered the positive form, and the data calculated by the Gravel layer is the Base. The corresponding pseudocode can be:
[0062] Base1 = Expand(Base);
[0063] Base2 = Shrink(Base);
[0064] Gravel New =max(Base2, Base1-MakeNoise(Base1));
[0065] Among them, Gravel New This is the Gravel layer after adding edge noise.
[0066] When adding edge noise to the base terrain layer, there are two methods depending on the order of addition: The first method is to calculate the masking data of each base terrain layer and then use the masking data to uniformly add edge noise to the junctions between different base terrain layers in a preset order; The second method is to calculate the masking data of the base terrain layers in sequence. After calculating the masking data of the first and second base terrain layers, the masking data of the first and second base terrain layers is used to perform edge optimization at the junctions between the first and second base terrain layers. Then the masking data of the third base terrain layer is calculated, and the junctions with the first and second base terrain layers are optimized, and so on.
[0067] In this embodiment of the invention, when the terrain mask calculated according to the terrain distribution rules is used to create a terrain scene, the edges of each terrain base layer are relatively harsh. Therefore, edge optimization is performed on the junctions of the terrain base layers, including PixelNormal blending and edge noise processing, to make the junctions of the terrain base layers more natural.
[0068] Specifically, the following embodiments provide methods for constructing the corresponding basic landform layer according to various landform distribution rules:
[0069] Based on the terrain data, select the preset terrain distribution rules corresponding to the terrain base layer in the scene to be rendered. The terrain base layer includes at least one or more of the first base layer, the second base layer, the third base layer, and the fourth base layer.
[0070] Based on terrain data and using selected landform distribution rules, the corresponding landform base layer in the scene to be rendered is decomposed and calculated, and environmental simulation calculations are performed to obtain the corresponding landform mask.
[0071] In this embodiment, the terrain base layer in the scene to be rendered is constructed according to the corresponding preset terrain distribution rules. One terrain base layer corresponds to one terrain distribution rule. Here, the terrain base layer can include at least one or more of the first base layer, the second base layer, the third base layer and the fourth base layer, and no specific limitation is made here.
[0072] In addition, the terrain distribution rules include the decomposition calculation of the terrain base layer and the environmental simulation calculation. The decomposition calculation of the terrain base layer means dividing the area of the corresponding terrain base layer from the scene to be rendered, while the environmental simulation calculation means performing corresponding environmental simulations based on the natural formation conditions of different terrain base layers for the area of the terrain base layer obtained above, such as water flow distribution simulation, gravity simulation, flow field simulation, torsion calculation, fluid calculation, etc., to obtain a terrain mask that closely resembles the natural terrain.
[0073] In one implementation, if the landform base layer is the first base layer, then based on the terrain data, the flow field mask of the first landform base layer is calculated, and points are evenly scattered on the flow mask to obtain multiple original points; the tangent direction of each original point is calculated, and each original point is moved according to the tangent direction according to a preset speed to obtain simulated water flow distribution information; the original points in the simulated water flow partial map are mapped to the height map corresponding to the terrain data to obtain the landform mask corresponding to the first base layer.
[0074] In this embodiment, the first geomorphic base layer can be the Flow layer, representing the area of bare soil formed by rainwater erosion. Therefore, when performing decomposition calculations on the geomorphic base layer, a flow field mask is calculated, and data points are evenly scattered on this mask. These data points simulate rainwater moving downwards along the tangent direction of the corresponding elevation map of the terrain data, i.e., decomposition calculations are performed using environmental simulation. This process is repeated until these data points flow to a suitable position, thus obtaining the area corresponding to the Flow layer obtained by simulating rainwater erosion. For example, Figure 3 As shown, the method for calculating the tangent direction is as follows:
[0075] Grad=-volumegradient(1,0,@P);
[0076] Norm = cross(oldNorm, Grad), as shown in 301, is an example of the corresponding movement direction;
[0077] Norm = cross(Norm, oldNorm), as shown in 301, is an example of the corresponding movement direction;
[0078] Specifically, by uniformly scattering data points and shifting them downwards a certain distance according to the new Norm direction, and repeating this process, a simulated water flow distribution map can be obtained. This water flow distribution map is then mapped onto a height map, using the data points as units, to obtain the final terrain mask corresponding to the first base layer.
[0079] In one implementation, if the landform base layer is a second base layer, then according to the terrain data and a preset first slope, gravity calculation and flow field calculation are performed on the second base layer to obtain the geometric information corresponding to the second base layer; according to the geometric information corresponding to the second base layer, geometric regions smaller than a preset first area are removed from the second base layer; the geometric regions in the second base layer are distorted and the height map corresponding to the terrain data is returned to obtain the corresponding landform mask.
[0080] In this embodiment, the second base layer can be a Gravel layer, representing the scree area at the lower part of the rock slope where the slope is slightly steep. Therefore, it is necessary to first select an appropriate slope range (i.e., the first slope, which is suitable for relatively steep slopes, preferably 10° to 50°), and use this first slope as the base data to perform gravity calculations and flow field calculations (for example, using Houdini's built-in node algorithm). Then, the obtained data is converted into geometric information (a geometric shape composed of dense points, where when the distance between two points is less than a preset distance, they are used to form the same geometric shape). Then, the area of each small region in the second base layer is determined according to the geometric information, and small regions with smaller areas are removed. Finally, distortion processing is performed to make the terrain effect more natural, and the processed data is converted back to the height map corresponding to the terrain data to obtain the terrain mask corresponding to the second base layer.
[0081] In one implementation, if the landform base layer is the third base layer, then according to the terrain data and a preset second slope, the flow field simulation calculation is performed on the third base layer to obtain the regional data corresponding to the third base layer; the regional data corresponding to the third base layer is remapped to a preset numerical range to obtain the landform mask corresponding to the third base layer.
[0082] In this embodiment, the third base layer can be the Debris layer, which represents the dry soil area of a small depression where rainwater collects at low altitudes. This landform is easily formed on gentle slopes. Therefore, an appropriate slope range (i.e., the second slope, preferably a gentle slope of 0° to 30°) can be selected first. Then, flow field simulation calculations are performed based on the gentle slope as the base data. The calculated data is then remapped to a preset numerical range (preferably between 0 and 1) to obtain the landform mask corresponding to the third base layer.
[0083] Preferably, after performing flow field simulation calculations on the basic data of the gentle slope, further screening can be carried out to find a gentler area (the slope range of the gentler area is preferably 0° to 15°), making it closer to the dry soil area of the third base layer. The data of this area is then remapped so that its value is between 0 and 1, resulting in a landform mask corresponding to the third base layer that better matches the environmental simulation.
[0084] In one implementation, if the geomorphic base layer is the fourth base layer, then based on the terrain data, the interval range corresponding to the fourth base layer is calculated according to a preset third slope and a preset height; the occlusion mask corresponding to the interval range is calculated, and the occlusion area in the fourth base layer is determined based on the occlusion mask; the geometric information corresponding to the occlusion area is calculated, and geometric areas smaller than a preset second area are removed from the fourth base layer based on the geometric information corresponding to the occlusion area; distortion calculation and fluid calculation are performed on the geometric areas in the fourth base layer, and the difference between the interval range and the calculated geometric area is processed, and the geomorphic mask corresponding to the fourth base layer is calculated based on the result of the difference processing.
[0085] In this embodiment, the fourth base layer can be the Slope layer, which represents the rocky slope area mainly distributed on the steep surface at high altitudes. Therefore, when the fourth base layer is obtained by decomposing and calculating from the scene to be rendered, it is necessary to determine the height range and slope range of the fourth base layer. Specifically, an appropriate height range can be selected and pre-set according to the art requirements, or determined according to the maximum and minimum heights of the scene to be rendered in proportion to the height. The slope range (i.e., the third slope, which is preferably a steep slope of 20° to 70°) is also set to filter out the approximate range of the fourth base layer.
[0086] Furthermore, since the data in this interval contains a large number of closed areas, the simulation effect of the rock slope in the fourth base layer is insufficient, so further optimization is needed. The optimization method can be as follows: filter out the closed areas, convert them into geometric shapes, remove data with areas smaller than a preset threshold, perform distortion and fluid calculations on the new data, and finally subtract the new data from the original approximate interval data to remove unreasonable areas and improve the simulation effect of the rock slope in the fourth base layer.
[0087] Specifically, after decomposing and calculating the scene to be rendered, the region of the fourth base layer is obtained. For unreasonable locations in the simulation of the rock slope, such as a small area in the fourth base layer with a relatively flat lower edge that does not match the irregular edge of the rock slope, and the area is relatively large (e.g., tens of meters wide in actual scale), a mask can be calculated for the region of the fourth base layer, and occlusion calculation can be performed to obtain a new occlusion mask that is slightly larger than the slope range. Then, the occlusion mask is transformed into a geometric shape, and small structures (areas with an area smaller than the preset value) are deleted. Next, the edges of the geometric region are distorted and fluid calculations are performed to make the simulation effect more natural. Then, the data corresponding to the region of the fourth base layer is subtracted from the geometric shape after distortion and simulation calculations to obtain a new region with a steeper slope, making the lower edge of the unreasonable small area more natural, and the overall region is reduced. Finally, the obtained region is remapped onto the height map to calculate the terrain mask corresponding to the fourth base layer.
[0088] If the geomorphic base layer also includes a fifth base layer, then the geomorphic mask corresponding to the third base layer is subjected to simulated erosion processing; the geomorphic mask after simulated erosion processing is remapped to obtain the geomorphic mask corresponding to the fifth base layer.
[0089] In this embodiment, the fifth base layer can be the erosion layer, which is the sedimentary soil area at the low-altitude slope and the junction of grassland and other landform base layers. It is the area formed by the erosion of the slope layer by wind and water. Therefore, the slope layer is used as the base layer for the calculation of the fifth base layer. During the calculation, the landform mask obtained from the slope layer is used as the original data for erosion simulation. The landform mask corresponding to the fifth base layer can be obtained by remapping the data after erosion simulation.
[0090] If the basic landform layer also includes a sixth basic layer, then the edge of the fifth basic layer is extended to obtain the landform mask corresponding to the sixth basic layer.
[0091] In this embodiment, the sixth base layer can be a Grass layer, representing the grassland area demarcated along the edge of other gently sloping areas. Here, it can represent the edge of other landform base layers. That is, after calculating other landform base layers, the closed interval of the edge is the sixth base layer (Grass layer). One method for calculating the edge of the sixth base layer is to expand the landform mask of other landform base layers and then subtract the original landform mask. For example, for the Gravel layer, the specific edge calculation method can be expressed as: Edge of the sixth base layer = Expand(Gravel) - (Gravel).
[0092] In this embodiment of the invention, by formulating the terrain distribution rules for each different terrain base layer, the same type of blocks are uniformly constructed to obtain the corresponding terrain base layer, thereby reducing the amount of resources required for terrain scene production.

[0097] In this embodiment of the invention, terrain data of the scene to be rendered is acquired; then, a terrain mask corresponding to the basic terrain layer in the scene to be rendered is constructed according to a preset terrain distribution rule, so that the terrain mask of each block in the scene to be rendered is uniformly constructed according to different types; finally, the corresponding terrain base layer can be mixed with materials according to the terrain mask to obtain the corresponding terrain scene. By using terrain distribution rules to replace block construction for terrain mask construction, the uniform construction of blocks of the same type in the game terrain scene is realized, thereby reducing the requirements for hardware performance and reducing the amount of resources required, thus improving the efficiency of game scene production, making large game terrain scenes suitable for mobile devices and easy to debug according to terrain distribution rules.
