The network 1004 serves as a medium for providing a communication link between the terminal apparatuses 1001, 1002, 1003 and the server 1005. The network 1004 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.

It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, the server 1005 may be a server cluster formed by a plurality of servers.

A user can interact with a server 1005 via a network 1004 using terminal apparatuses 1001, 1002, 1003 to receive or transmit messages or the like.

In the related art, a game scene may be created by software such as Unity. In making a game scene, it is often necessary to modify and adjust the topography in the game scene. In the development process, a plurality of terrain models are respectively manufactured. However, the terrain models manufactured separately cannot be combined into an integral terrain, the artistic effect needs to be manufactured again, the manufacturing cost is high, the efficiency is low, and the artistic quality is difficult to ensure.

In the terrain model merging method provided by the embodiment of the disclosure, a first gray level map of a basic terrain model can be obtained, a second gray level map of a merged terrain model is obtained, the first gray level map and the second gray level map are fused to obtain a fused gray level map, and the merged terrain model is subjected to terrain mapping to the basic terrain model based on the fused gray level map to obtain a target terrain model after the basic terrain model and the merged terrain model are merged.

Referring to fig. 2, a flowchart illustrating a terrain model merging method in the present exemplary embodiment may include the steps of:

step S210: acquiring a first gray level map of a basic terrain model, and acquiring a second gray level map of a combined terrain model;

step S220: fusing the first gray scale image and the second gray scale image to obtain a fused gray scale image;

step S230: and carrying out terrain mapping on the combined terrain model to the basic terrain model based on the fusion gray map to obtain a target terrain model after the basic terrain model and the combined terrain model are combined.

Next, steps S210 to S230 of the terrain model merging method in the present exemplary embodiment will be described in more detail with reference to fig. 2 and the embodiment.

Step S210, a first gray level map of a basic terrain model is obtained, and a second gray level map of a combined terrain model is obtained;

in one example embodiment of the present disclosure, a first gray scale map of a base terrain model may be acquired, and a second gray scale map of a merged terrain model may be acquired. Specifically, the basic terrain model and the merged terrain may be terrain elements in the game scene, where the basic terrain model may be an atmospheric terrain model and the merged terrain model may be a special terrain model, and in order to merge the merged terrain model onto the basic terrain model, a first gray map of the basic terrain model may be obtained, and a second gray map of the merged terrain model may be obtained. And based on the first gray level map of the basic terrain model, acquiring a second gray level map of the combined terrain model to combine the basic terrain model and the combined terrain model. The combined terrain model refers to a terrain model to be combined, namely, a basic terrain model and the combined terrain model are required to be combined.

In the solution of the present disclosure, the hierarchical relationship between the basic terrain model and the merged terrain model is not limited, and the basic terrain model and the merged terrain model are only used for distinguishing the two terrain models.

For example, the basic terrain model may be a hillside model, the merged terrain model may be a hillside model, and the two hillside models may be merged.

In one example embodiment of the present disclosure, the underlying terrain model and the merged terrain model may be generated by a variety of three-dimensional software. For example, the basic terrain model and the merged terrain may be generated by Blender (three-dimensional modeling software), maya (three-dimensional modeling software), 3ds Max (3D Studio Max), or the like.

The present disclosure is not limited to a specific manner of generating the basic terrain model and combining the terrains.

In one example embodiment of the present disclosure, a first gray scale map of a base terrain model may be acquired, and a second gray scale map of a merged terrain model may be acquired. Specifically, after the basic terrain model and the merged terrain model are created, and after rendering in the virtual game scene is completed, a first gray scale map of the basic terrain model and a second gray scale map of the merged terrain model may be derived. The first gray level map of the basic terrain model is used for indicating the height information of each position in the basic terrain model, the first gray level map of the basic terrain model can be used for indicating the height information, the terrain features, the gradient or the slope direction and the like of the basic terrain model, the second gray level map of the combined terrain model is used for indicating the height information of each position in the combined terrain model, and the second gray level map of the combined terrain model can be used for indicating the height information, the terrain features, the gradient or the slope direction and the like of the combined terrain model.

For example, in a gray scale map, the larger the gray scale of a point, the higher the height of the point; the smaller the gray level of a certain point, the higher and lower the height of that point.

For example, as shown in fig. 3a, a schematic diagram of a first gray scale map of the underlying terrain model; as shown in fig. 3b, a schematic diagram of a second gray scale map of the merged terrain model is shown. Wherein, the larger the gray level of a certain point is, the higher the height of the point is; the smaller the gray level of a certain point, the higher and lower the height of that point.

In one example embodiment of the present disclosure, the underlying terrain model is regular terrain, i.e., the length and width of the underlying terrain model is rectangular.

It should be noted that, the specific manner of acquiring the first gray scale map of the basic terrain model and acquiring the second gray scale map of the merged terrain model is not particularly limited in the present disclosure.

Step S220, fusing the first gray scale image and the second gray scale image to obtain a fused gray scale image;

in an example embodiment of the present disclosure, after the first gray scale map of the basic terrain model and the second gray scale map of the merged terrain model are obtained through the above steps, the first gray scale map and the second gray scale map may be fused to obtain a fused gray scale map. Specifically, when fusion is performed, a preset mode can be selected for fusion.

For example, the first gray scale map and the second gray scale map may be fused by superposition, averaging, multiplication, fusion, and the like, to obtain a fused gray scale map.

In an example embodiment of the present disclosure, when the first gray scale map and the second gray scale map are fused to obtain a fused gray scale map, a maximum value of gray scales at the same position in the first gray scale map and the second gray scale map may be taken, and the fused gray scale map may be determined based on the maximum value of gray scales at each position.

In an example embodiment of the present disclosure, when the first gray scale map and the second gray scale map are fused to obtain a fused gray scale map, a minimum value of gray scales at the same position in the first gray scale map and the second gray scale map may be taken, and the fused gray scale map may be determined based on the minimum value of gray scales at each position.

In an example embodiment of the present disclosure, when the first gray scale map and the second gray scale map are fused to obtain a fused gray scale map, a specific position may be selected in the first gray scale map or the second gray scale map for fusion.

For example, a part of gray scale map may be selected from the second gray scale map and fused with the first gray scale map to obtain a fused gray scale map.

In an example embodiment of the present disclosure, when the first gray scale map and the second gray scale map are fused to obtain a fused gray scale map, partial features of the first gray scale map and the second gray scale map may be obtained in the first gray scale map and the second gray scale map, respectively, and fused based on the partial features of the first gray scale map and the partial features of the second gray scale map.

For example, when the first gray scale image and the second gray scale image are fused, the details of the first gray scale image can be emphasized, and the whole shape or texture feature of the second gray scale image is added, so that a better artistic effect is achieved.

For example, as shown in fig. 4, after the first gray scale 401 of the basic terrain model and the second gray scale 402 of the merged terrain model are obtained through the above steps, the first gray scale 401 and the second gray scale 402 are fused to obtain a fused gray scale 403.

In an example embodiment of the present disclosure, a gray-scale preset maximum value may be set, and both the maximum value of gray scales in the first gray-scale map and the maximum value of gray scales in the second gray-scale map are smaller than the preset maximum value of gray scales.

Note that, the specific manner of fusing the first gray scale image and the second gray scale image to obtain the fused gray scale image is not particularly limited in the present disclosure.

And step S230, performing terrain mapping on the combined terrain model to the basic terrain model based on the fusion gray map to obtain a target terrain model after combining the basic terrain model and the combined terrain model.

In an example embodiment of the present disclosure, after the fused gray map is obtained through the above steps, the merged terrain model may be mapped to the base terrain model based on the fused gray map, to obtain a target terrain model after the base terrain model and the merged terrain model are merged. Specifically, the basic terrain model can be used as a frame or a foundation for terrain mapping, the basic terrain model can be used as a foundation layer of terrain mapping, information such as the height, the terrain features, the gradient or the slope direction of each position of the combined target terrain model is determined through fusion gray level diagrams, and the target terrain model is generated based on the information such as the height, the terrain features, the gradient or the slope direction of each position of the target terrain model.

For example, as shown in fig. 5a, a schematic diagram of a combined terrain model to a basic terrain model based on a fused gray scale map is shown, so as to obtain a target terrain model (side view) 503 after combining the basic terrain model (side view) 501 and the combined terrain model (side view) 502, wherein an arrow in the figure is a mapping direction of the terrain map, and a shadow part is the combined target terrain model (side view) 503; as shown in fig. 5b, another schematic diagram of performing terrain mapping on the merged terrain model to the basic terrain model based on the merged gray scale map to obtain a merged target terrain model (side view) 506 of the basic terrain model (side view) 504 and the merged terrain model (side view) 505, where an arrow in the figure is a mapping direction of the terrain mapping, and a shadow portion is the merged target terrain model (side view) 506.

In an example embodiment of the present disclosure, the region corresponding to the basic terrain model is larger than the region of the merged terrain model, and when the merged terrain model is mapped to the basic terrain model based on the merged gray map, there is a mapping region smaller than the region corresponding to the basic terrain model.

The specific manner of obtaining the target terrain model after combining the basic terrain model and the combined terrain model by performing terrain mapping on the combined terrain model to the basic terrain model based on the fusion gray map is not particularly limited.

In an example embodiment of the present disclosure, after the first gray scale map of the basic terrain model and the second gray scale map of the merged terrain model are obtained through the above steps, gray scales in the first gray scale map and/or the second gray scale map may be adjusted. Specifically, the adjustment of the gray scale in the first gray scale map and/or the second gray scale map refers to the adjustment of the height information of each position in the basic terrain model and/or the merged terrain model, that is, the adjustment of the gray scale at any position in the first gray scale map and/or the second gray scale map can be performed to control the height information of the final merged target terrain model, that is, the control of the height, the terrain feature, the gradient or the slope direction of the final merged target terrain model.

In an example embodiment of the present disclosure, a merge area that merges the merge terrain model into the base terrain model may be obtained, a third gray scale map is determined in the first gray scale map based on the merge area, and the third gray scale map is fused with the second gray scale map to obtain a fused gray scale map. Referring to fig. 6, determining a target terrain model based on the first terrain model and the second terrain model may include the following steps S610 to S630:

Step S610, acquiring a merging area for merging the merging terrain model into the basic terrain model;

in one example embodiment of the present disclosure, after the basic terrain model and the merged terrain model are obtained through the above steps, a merge area that merges the merged terrain model into the basic terrain model may be obtained. Specifically, the merging region in which the merged terrain model is merged into the base terrain model refers to a mapping region when the merged terrain model is mapped to the base terrain model based on the merged gray scale map, that is, a position where the base terrain model and the merged terrain model overlap when the base terrain model and the merged terrain model are merged.

Note that, the shape and position of the merging region are not particularly limited in the present disclosure.

Step S620, determining a third gray scale map in the first gray scale map based on the merge region; wherein the third gray scale map corresponds to the merging region;

in one example embodiment of the present disclosure, after determining the merge region, a third gray scale map may be determined in the first gray scale map based on the merge region. Wherein the third gray scale map corresponds to the merge region. Specifically, the third gray scale map is a gray scale map of a superposition portion of the first gray scale map and the second gray scale map in the first gray scale map, and the superposition portion corresponds to the merging region.

Step S630, fusing the third gray scale image and the second gray scale image to obtain a fused gray scale image.

In an example embodiment of the present disclosure, after the third gray scale map is obtained through the above steps, the third gray scale map and the second gray scale map may be fused to obtain a fused gray scale map. Specifically, the step of fusing the third gray scale image and the second gray scale image to obtain a fused gray scale image means that the gray scale image of the overlapping portion of the first gray scale image and the second gray scale image in the first gray scale image is fused with the second gray scale image, the size and the shape of the fused gray scale image obtained after the fusion are the same as those of the second gray scale image, and in the fused gray scale image, only the region corresponding to the third gray scale image is fused.

Specifically, when fusion is performed, a preset mode can be selected for fusion.

For example, the third gray scale map and the second gray scale map may be fused by superposition, averaging, multiplication, fusion, and the like to obtain a fused gray scale map.

In an example embodiment of the present disclosure, when the third gray scale map and the second gray scale map are fused to obtain a fused gray scale map, a maximum value of gray scales at the same position in the third gray scale map and the second gray scale map may be taken, and the fused gray scale map may be determined based on the maximum value of gray scales at each position.

In an example embodiment of the present disclosure, when the third gray scale map and the second gray scale map are fused to obtain a fused gray scale map, a minimum value of gray scales at the same position in the third gray scale map and the second gray scale map may be taken, and the fused gray scale map may be determined based on the minimum value of gray scales at each position.

In an example embodiment of the present disclosure, when the third gray scale map and the second gray scale map are fused to obtain a fused gray scale map, a specific position may be selected in the third gray scale map or the second gray scale map for fusion.

For example, a part of gray scale images may be selected from the second gray scale image and fused with the third gray scale image to obtain a fused gray scale image.

In an example embodiment of the present disclosure, when the third gray scale image and the second gray scale image are fused to obtain a fused gray scale image, partial features of the third gray scale image and the second gray scale image may be obtained in the third gray scale image and the second gray scale image, respectively, and fused based on the partial features of the third gray scale image and the partial features of the second gray scale image.

For example, when the third gray scale image and the second gray scale image are fused, the details of the third gray scale image can be emphasized, and the whole shape or texture feature of the second gray scale image is added, so that a better artistic effect is achieved.

Note that, the specific manner of fusing the third gray scale image and the second gray scale image to obtain the fused gray scale image is not particularly limited in the present disclosure.

Through steps S610 to S630, a merging area for merging the merged terrain model into the basic terrain model may be obtained, a third gray scale map is determined in the first gray scale map based on the merging area, and the third gray scale map and the second gray scale map are merged to obtain a merged gray scale map.

In an example embodiment of the present disclosure, a fourth gray scale map is determined in a first gray scale map according to a merging area, a merging terrain model is mapped to a base terrain model based on the merging gray scale map, a first terrain model obtained by merging the base terrain model and the merging terrain model at the merging area is obtained, a second terrain model at the base area is obtained according to the fourth gray scale map, and a target terrain model is determined based on the first terrain model and the second terrain model. Referring to fig. 7, determining a target terrain model based on the first terrain model and the second terrain model may include the following steps S710 to S730:

step S710, determining a fourth gray scale map in the first gray scale map according to the merging area;

in one example embodiment of the present disclosure, after the merging region is determined through the above-described steps, a fourth gray scale map may be determined in the first gray scale map according to the merging region. Wherein the fourth gray scale map corresponds to a base region outside the merge region. Specifically, in the first gray scale map, other areas except the merging area may be determined, and the gray scale map corresponding to the areas may be used as the fourth gray scale map.

Note that, the specific manner of determining the fourth gray scale map in the first gray scale map according to the merging area is not particularly limited in the present disclosure.

Step S720, performing terrain mapping on the combined terrain model to the basic terrain model based on the fusion gray map to obtain a first terrain model obtained by combining the basic terrain model and the combined terrain model at the combined area;

in an example embodiment of the present disclosure, after the fused gray map is obtained through the above steps, the merged terrain model may be mapped to the base terrain model based on the fused gray map, to obtain a first terrain model in which the base terrain model and the merged terrain model are merged at the merging area. Specifically, the basic terrain model at the merging area can be used as a frame or foundation for terrain mapping, the basic terrain model at the merging area can be used as a foundation layer of terrain mapping, the information such as the height, the terrain features, the gradient or the slope direction of each position of the merged first terrain model at the merging area is determined through the merging gray map, and the first terrain model is generated based on the information such as the height, the terrain features, the gradient or the slope direction of each position at the merging area.

Step S730, obtaining a second terrain model at the base area according to the fourth gray scale map, and determining a target terrain model based on the first terrain model and the second terrain model.

In one example embodiment of the present disclosure, after the fourth gray scale map is obtained through the above steps, the second terrain model at the base area may be obtained based on the fourth gray scale map. Specifically, the fourth gray scale map may be used to indicate information such as a height, a topography feature, a gradient, or a slope direction of the second terrain model at each position of the base area, and the second terrain model may be generated based on the information such as the height, the topography feature, the gradient, or the slope direction of the second terrain model at each position of the base area.

In one example embodiment of the present disclosure, the target terrain model may be determined based on the first terrain model and the second terrain model. Specifically, the first terrain model and the second terrain model may be combined to obtain the target terrain model.

Specifically, the basic terrain model corresponds to a plurality of terrain materials, the merging terrain model corresponds to a plurality of terrain materials, and the plurality of terrain materials corresponding to the basic terrain model and the plurality of terrain materials corresponding to the merging terrain model can be merged into a plurality of target terrain materials to be adopted by the target terrain model.

Wherein in the rendering of the terrain model, the terrain material may be used to describe the terrain surface appearance and texture. The terrain model may have a plurality of terrain materials, the material type of each terrain material being different, and the region of action of each terrain material may also be different.

Specifically, merging the plurality of terrain materials corresponding to the basic terrain model and the plurality of terrain materials corresponding to the merged terrain model into the plurality of target terrain materials to be adopted by the target terrain model may include directly merging the plurality of terrain materials corresponding to the basic terrain model and the plurality of terrain materials corresponding to the merged terrain model, or may include respectively performing operations such as merging, mixing, overlapping and the like on the plurality of terrain materials corresponding to the basic terrain model and the plurality of terrain materials corresponding to the merged terrain model so as to generate new terrain materials, wherein the new terrain materials are the target terrain materials.

In one example embodiment of the present disclosure, when the number of the plurality of target terrain textures is greater than a preset threshold, duplicate terrain textures are searched for in the plurality of target terrain textures, and duplicate terrain textures are deleted in the plurality of target terrain textures.

In an example embodiment of the present disclosure, after the target terrain texture is obtained through the above steps, the repeated terrain texture may be searched for among the plurality of target terrain textures when the number of the plurality of target terrain textures is greater than a preset threshold. Specifically, in the three-dimensional modeling software, aiming at the same model, at most, a preset number of materials can be provided, when the number of the plurality of target topographic materials is larger than a preset threshold value, the number of the materials representing the current target topographic materials is larger than the preset threshold value, at this time, repeated topographic materials can be searched in the target topographic materials, and the repeated topographic materials are deleted, so that only one identical target topographic material exists, the number of the target topographic materials is reduced, and the number of the plurality of target topographic materials is ensured to be smaller than or equal to the preset threshold value.

In an example embodiment of the present disclosure, in the three-dimensional modeling software, the target terrain texture corresponds to a terrain texture ID (identifier), and the repeated terrain texture ID may be deleted, so that the target terrain texture corresponding to the terrain texture ID is deleted.

Through the steps S910 to S920, when the number of the plurality of target topographic materials is greater than the preset threshold, the repeated topographic materials may be searched for in the plurality of target topographic materials, and the repeated topographic materials may be deleted from the plurality of target topographic materials.

In one example embodiment of the present disclosure, a coverage relationship between a plurality of target terrain materials is adjusted. Specifically, a coverage relationship exists among the plurality of target topographic materials, and the coverage relationship among the target topographic materials can be adjusted in response to a coverage relationship adjustment operation.

For example, the target terrain materials include terrain material 1, terrain material 2, terrain material 3, terrain material 4, and before being adjusted, the coverage relationship of the target terrain materials is: the topography material 2, topography material 3, topography material 1, topography material 4, after adjusting, this coverage relation of a plurality of target topography materials is: topography material 3, topography material 2, topography material 1, topography material 4.

In an example embodiment of the present disclosure, in the three-dimensional modeling software, the target terrain texture corresponds to the terrain texture ID, and the terrain texture ID may be adjusted, so as to adjust the coverage relationship between the target terrain textures corresponding to the plurality of terrain texture IDs.

The specific manner of adjusting the coverage relationship between the plurality of target topographic materials is not particularly limited in the present disclosure.

In one example embodiment of the present disclosure, a texture conflict is found among a plurality of target terrain textures, and the conflicting terrain textures are merged. Specifically, when combining a plurality of terrain materials corresponding to a basic terrain model and a plurality of terrain materials corresponding to a combined terrain model, a situation of material collision occurs, specifically, in three-dimensional modeling software, a target terrain material corresponds to a terrain material ID, in the plurality of target terrain materials after combination, if the same terrain material ID corresponds to the same terrain material, no material collision exists, if the same terrain material ID corresponds to different terrain materials, the different terrain materials can generate material collision, and at this time, the target terrain materials generating the material collision can be combined.

In an example embodiment of the present disclosure, as shown in fig. 10, after merging a plurality of terrain materials corresponding to a basic terrain model and a plurality of terrain materials corresponding to a merged terrain model to obtain a plurality of target terrain materials, the following processing may be performed on the plurality of target terrain materials, and may include the following steps S1001 to S1006:
