[0081] In this embodiment, the height of the black-and-white height map needs to be sampled, such as the height data of the Z-axis of the grid model, the height is mapped to the corresponding gray color, and finally a height map with different gray scales is generated, so that the terrain is regionally divided based on the height, which is beneficial to the subsequent processing of brightness, texture and / or color, chroma.

[0082] Further, in an embodiment of the application, the terrain generation method for visualizing network attack and defense situation provided in the application, the generation of the scene model according to the black-and-white height map comprises:

[0083] By adjusting the noise parameters and the erosion parameters corresponding to the black-and-white height map, a predetermined type of detail texture and / or gully is generated.

[0084] In this embodiment, by adjusting the noise parameters and the erosion parameters of the black-and-white height map, a predetermined type of detail texture and gully is generated, wherein the predetermined type refers to that different types of filling areas correspond to different textures, such as filling a certain snow texture in the mountain top area, and the like, wherein the noise parameters include the noise persistence CMp, the frequency multiplication CCpu and the noise point spacing CD, and the specific detail texture processing process is shown in the following embodiments and is not described in detail here.

[0087] According to different gray scales and / or detail textures, corresponding color filling is performed.

[0088] In this embodiment, according to different gray scales and / or detail textures, corresponding color filling is performed, for example, the area under the mountain foot can be filled with green plants, shrubs and other textures.

[0089] According to the battlefield terrain generation method for visualizing network attack and defense situation provided by the present application, different predetermined types of detail textures are filled with corresponding colors, so that the terrain map is more rich in performance and better in visual experience.

[0093] In this embodiment, the to-be-filled area of different textures is calculated according to the mountain height and surface slope, wherein each to-be-filled area can be a snow-capped mountain area, a middle steep cliff area or a mountain foot gentle slope area. According to the determined to-be-filled area, the corresponding filling texture and the corresponding color are determined, for example, the mountain foot gentle slope area needs to be filled with green trees, grassland and other textures, the snow-capped mountain area needs to be filled with snow texture, the cliff area needs to be filled with rock texture, and the flat area needs to be filled with grassland texture.

[0094] It should be noted that in this embodiment, the to-be-filled area is filled with a preset material and color in the application program unity through the RGBA color channel, and then a terrain map with detail texture is generated. Specifically, it can also be other application programs, which are not limited here.

[0095] According to the battlefield terrain generation method for visualizing network attack and defense situation provided by the present application, the to-be-filled area is filled with a preset material and color in the application program through the RGBA color channel, and a terrain map with detail texture is generated, so that the terrain map content is detailed, and the visual display effect of the terrain map is improved.

[0096] Further, in an embodiment of the present application, the method for generating a terrain for visualizing a cyber attack and defense situation according to the present application, the determination of each to-be-filled region according to different gray scales and / or detail textures comprises:

[0097] The black-and-white height map is divided according to the relationship between each height in the black-and-white height map and a preset height threshold, the relationship between a surface slope and a preset surface slope threshold, and / or different detail texture types, to determine each to-be-filled region.

[0098] In this embodiment, the black-and-white height map can be accurately divided by the preset height threshold and the slope threshold, to obtain corresponding mountain top to-be-filled regions, mountain foot to-be-filled regions, cliff to-be-filled regions, etc. Assuming that the preset height thresholds are 10 m, 20 m and 30 m respectively, and the corresponding slopes are 20%, 30% and 40% respectively, when the obtained height value is 5 m and the slope is 10%, the corresponding region is determined to be a mountain foot to-be-filled region, and the corresponding grassland texture is filled. It should be noted that the sizes of the preset height threshold and the preset slope threshold can be set according to actual needs of a user, and are not limited herein.

[0099] The method for generating a battlefield terrain for visualizing a cyber attack and defense situation according to the present application, by comparing the height value with the preset height threshold and the slope value with the preset slope threshold, determines the corresponding to-be-filled region, and directly fills the corresponding texture, thereby improving the efficiency of terrain map generation.

[0100] Further, in an embodiment of the present application, the method for generating a terrain for visualizing a cyber attack and defense situation according to the present application, the obtaining of a picture with a predetermined outer contour comprises:

[0101] The picture with the predetermined outer contour is obtained as a tiger shape.

[0105] The battlefield terrain generation method for visualizing network attack and defense situation provided by the present application sets the outer contour as a tiger shape or other predetermined shape, which is beneficial to overall design and individualized design of the entire terrain map.

[0106] Further, in an embodiment of the present application, the generation of the black-and-white height map is processed by using a parameterization tool, specifically, a black-and-white planar map with a predetermined outer contour is superimposed on a mountain map (noise map), then a wind erosion algorithm is added to offset the vertices of the surface slope of the mountain range and the concave-convex part of the mountain body to different degrees, and the height of the grid model Z-axis is sampled to map the height to the corresponding gray color, and finally a mountain black-and-white height map is generated.

[0107] It should be noted that the input of the above processing mode is a black-and-white boundary map with an outer contour and a mountain trend line data. If it is necessary to change the mountain shape, the output result can be changed by adjusting the black-and-white boundary map and adjusting the vertices on the line.

[0108] In the present embodiment, the corresponding detail texture is obtained by adjusting the noise parameters and the parameters of the wind erosion algorithm, such as simulating various mountains such as deserts and karst landforms. It should be noted that the filling area of different textures needs to be calculated according to the height and surface slope of the mountain body, such as the snow-covered mountain area at the top, the steep cliff area in the middle, and the gentle slope area at the foot, and different colors are assigned to different areas. Specifically, different color materials are filled in unity according to the RGBA color channel, such as filling snow texture in the mountain top area, filling rock texture in the cliff area, and filling grassland texture in the flat area. The related parameters of the wind erosion algorithm include rock hardness KHb, earthwork carrying degree KCu, weathering time KTi, height KH and slope KS. The related parameters of the noise algorithm include noise persistence CMp, frequency multiplication CCpu and noise point spacing CD.

The non-destructive modeling method adopted by the present application can generalize the terrain contour into various shapes by only providing a black-and-white boundary map with an outer contour, and can change the final model result by returning and modifying any input parameter at any time. This new parameterization process reduces the traditional terrain generation time from one week to two days, and can quickly iterate the appearance, thereby reducing the labor cost.
