Background

Currently, there is an increasing number of open world themed games, with a large amount of natural terrain contained in the scene area of such games.

Secondly, the reduction of the terrain slope can stretch the environmental map to a certain degree. However, excessive stacking of models increases performance consumption and grade reduction may increase limitations in visual performance.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

The embodiment of the application provides a method and a device for processing terrain data in a game. The following examples are individually set forth.

In a game having a large number of natural terrains, a user can move in various terrains in a game scene area and perform game operations such as fighting, construction, detection of mineral resources or planting. By natural topography is meant a simulation of real world topography, such as different terrains like mountains, plains, forests etc. When the terrain is in large fluctuation, the terrain displayed in the game interface can be stretched in different degrees, so that the visual effect rendered in the game is poor. For example, for cliffs, steep slopes, steep sills, etc., the visual effect of the decal after stretching is quite different from that of real natural terrain. In the technical scheme of the prior art, generally, in the case of stretching a relatively obvious map, models such as rocks and mountains are adopted to cover the stretched terrain map, or the slope of the terrain is reduced to solve the stretching influence. However, the use of the masking scheme significantly increases the performance consumption of the client when there is too many model stacks. Reducing the slope to alleviate the stretch of the artwork increases the limitations of the artistic expression.

In the method provided by the embodiment of the application, the problem of the chartlet stretching possibly occurring when the terrain gradient is large is solved by using the graphic material function, so that the visual effect of the terrain in the game is closer to reality.

For ease of understanding, a description of the system architecture of the method provided by the embodiments of the present application is given below in conjunction with fig. 1. In the system architecture example shown in fig. 1, the method comprises the following steps: a user terminal 101, a server terminal 102 and a development terminal 103. The user terminal 101 in this embodiment may be, but is not limited to, a portable terminal, a mobile phone, a PAD, a personal computer, or an electronic device with an image processing function, and is used for running a game program including natural terrain, and the visual appearance of the game program is closer to reality in the case where there is a large slope and/or undulation in the natural terrain. The user terminal 101 and the server terminal 102 are connected to each other through a communication network, which may include a mobile network, a gateway, and the internet, or may be composed of a local area network and the internet. For example: the user terminal 101 is connected to the server terminal 102 via a mobile network, a gateway, and the internet. The following steps are repeated: the user terminal 101 is connected to the server terminal 102 via a local area network and the internet. The user terminal 101 receives information input by the game user, loads and executes a game program, and the game program is communicated with the game program executed by the server terminal 102 through a communication protocol. The game program executed by the server 102 may provide, but is not limited to, the following functions: configuration, management, related data calculation or other processing such as storage, data interaction processing with other game users (if multiple game users or networked games for team or match-up), etc. The development end 103 generates design data such as scene maps, various templates, user interfaces, user interaction and the like in the game according to information such as virtual camera lens movement, role operation, game running logic and the like in a pre-designed game, and realizes association and running logic of various resources in the game. In the embodiment of the present application, the development end 103, in particular, generates the terrain data including one or more terrain objects in the game, and the terrain data is uploaded to the service end 102 along with the game generated by the development end 103 and is loaded to the user end 101 along with the game user loading the game, or is gradually loaded to the user end 101 along with the game user operating in the game, and is rendered as a scene map or terrain in the game at the user end 101.

A method for processing topographic data in a game according to a first embodiment of the present application will be described below with reference to fig. 2 to 6. The method for processing terrain data in the game shown in fig. 2 comprises the following steps: step S201 to step S204.

Step S101, determining a target object to be processed in the topographic data of the game.

In this embodiment, the game refers to a terrain-like game including terrain data simulating natural terrain, such as an open-world theme game. The terrain data comprises one or more terrain objects, and each terrain object in the game may be considered an object formed based on a terrain shape and a terrain surface type. The terrain modeling can be a polygon, and the terrain surface type can be a terrain map. The terrain surface type may be any of the following terrain materials from the image: mountainous regions, plains, forests, deserts, water areas, swamps or terrains made of personalized customized materials and the like. The terrain map is applied to the terrain modeling surface, so that the rendered terrain object can present a visual appearance similar to the terrain in the real world in a game interface of a user side, and particularly present a three-dimensional appearance. For example, appearing as three-dimensional mountains, deserts, etc. The terrain map may be a two-dimensional picture, and is particularly applied to a terrain modeling surface according to UV coordinates, so that the terrain object is rendered to appear as a three-dimensional appearance. The UV coordinate is a coordinate of the picture in the horizontal and vertical directions of the display, and the value of the UV coordinate is 0-1. For example, the U-th pixel in the horizontal direction represents the horizontal position of the pixel, and the V-th pixel in the vertical direction represents the vertical position of the pixel. Each point on the terrain map can be corresponding to the surface of the terrain modeling through the UV coordinates, the position of a gap between each point and each other is subjected to smooth interpolation processing, and if the gradient of the terrain modeling is large, the problem of map stretching, particularly texture stretching, is caused when the two-dimensional terrain map is projected on the polygonal terrain modeling surface.

This step is to determine a terrain object to be processed in the game due to the gradient of the terrain shape, the terrain object being the target object. In practice, it can be determined whether the object is a target object with a large gradient or a large undulation degree according to the angle between the vertex of the object currently picked up in the game and the horizontal plane of the terrain data or the preset mark of each object. Specifically, the determining a target object to be processed in the topographic data of the game includes: acquiring an object in topographic data of a game, and determining the object as a target object to be processed according to an angle between the object and a horizontal plane of the topographic data; or acquiring attribute configuration data of the object in the topographic data, and if the attribute configuration data comprises a preset stretching processing mark, determining that the object is a target object to be processed. Wherein, the stretching processing mark is a mark which is set for creating an object (especially a terrain object) and indicates that the object has larger gradient or larger fluctuation degree and needs processing.

Further, the determining the object as a target object to be processed according to an angle between the object and a horizontal plane of the terrain data includes: and if the angle between the surface line of the object and the horizontal plane is smaller than a first gradient threshold value, or the included angle between the normal direction corresponding to the surface of the object and the normal direction corresponding to the horizontal plane is larger than a second gradient threshold value, taking the object as the target object. For example, the angle between the surface line of the object and the horizontal plane is less than 120 degrees, or the angle between the normal corresponding to the surface of at least some slope of the object and the normal corresponding to the horizontal plane is greater than 70 degrees, which may be regarded as a slope or a heave.

In this embodiment, the topographic data refers to topographic data currently loaded into the memory. In fact, the topographic data can be dynamically loaded according to the position of the character in the game, or the topographic data of the whole game can be loaded at one time. The method also comprises the following steps: and according to the position movement of the virtual camera corresponding to the game relative to the terrain data, picking up an object of which the distance between the object and the virtual camera in the terrain data is smaller than a preset distance threshold value, and further judging whether the picked object is a target object needing stretching processing. The virtual camera in this embodiment refers to a game component that observes a game world in a different mode and/or a different viewpoint in a game, for example, a game scene observed from a viewpoint of a character in a game corresponding to a game user.

Step S102, obtaining a texture map and a normal map contained in the target object.

In this embodiment, data forming the topographic surface type of the target object, that is, a topographic map, is specifically obtained, and a texture map, that is, a normal map, in the topographic map is further extracted for processing in subsequent steps, so as to solve the problem of mapping texture stretching.

Step S103, outputting first tile mapping data corresponding to the texture map and second tile mapping data corresponding to the normal map according to each predetermined coordinate direction of the terrain data.

In this embodiment, the predetermined coordinate direction is a coordinate direction in a world position coordinate system in the game, such as XYZ three-dimensional coordinate direction. During implementation, the world space texture coordinates of the target object can be identified by using the graph material function, and the textures in different directions of XYZ are tiled and mapped, so that the problem of terrain mapping stretching is solved. Specifically, the world space texture coordinates of the texture map are identified through a graph material function corresponding to the texture map, and tiling mapping is performed in the three-dimensional position coordinate direction of the topographic data to obtain first tiling mapping data; and identifying world space texture coordinates of the normal map through a graph material function corresponding to the normal map, and performing tiling mapping in the three-dimensional position coordinate direction of the topographic data to obtain second tiling mapping data.

The image material function is a world consistent texture function (WorldAlignedTexture) including a plurality of nodes. Specifically, the input information of each node in the corresponding world-consistent texture function is acquired for the texture map and the normal map, and is input to the corresponding node for data processing. In practice, the method may specifically include: respectively converting the texture mapping and the normal mapping into a corresponding texture object and a normal texture object, and respectively inputting texture object nodes contained in the corresponding world consistent texture functions; respectively picking up respective absolute world coordinate values of the texture map and the normal map, and respectively inputting the respective absolute world coordinate values into absolute world coordinate nodes contained in world material functions corresponding to the texture map and the normal map; and acquiring texture repetition degree data of the texture map and the normal map, and respectively inputting texture size nodes contained in the world material function corresponding to the texture map and the normal map. So-called texture repetition degree data can be obtained from the feature data of the target object. For example, the absolute world coordinate values of the current object (i.e., the target object) are picked up by the WorldPosition node in the graph material function and directly inserted into an absolute world coordinate node (AbsoluteWorldPosition) to better match the texture of each predetermined coordinate direction, thereby solving the problem of map stretching. For example, the texture repetition degree data may be data for controlling a horizontal tiling amount and a vertical tiling amount of a point in a map, may be determined according to a specific game scene, and may also obtain an empirical value, for example, an effect that the data in a realistic scene makes a size of a target object presented in an interface close to an actual size.

In this embodiment, the visual effect of the seam portion in different projection directions can be buffered by obtaining the data of transition fusion between the mapping textures in different position coordinate directions. The method specifically comprises the following steps: and acquiring respective fusion transition parameter values of the texture map and the normal map, and respectively inputting projection transition contrast nodes contained in the world material functions corresponding to the texture map and the normal map.

In this embodiment, if the texture map is applied to the terrain modeling surface of the target object (i.e. the terrain object) in the form of a texture mask, the method further includes: and setting the Alpha channels of the texture mapping and the normal mapping to be in an opening state.

In this embodiment, the method further includes: and acquiring world space vertex normals of the target object, and respectively inputting world space normal nodes contained in world consistent texture functions corresponding to the texture maps and the normal maps, so as to determine the normal directions of upper directional axes of the texture maps and the normal maps. This may result in a higher degree of matching between the mapped textures for each predetermined coordinate direction.

In this embodiment, in order to reduce the effect of the terrain stretching degree and maintaining the terrain in a horizontal plane when the terrain map is applied to the terrain object, the method further includes: and according to the world texture coordinate data of the normal map, carrying out reverse operation on the upper direction of the normal map. For example, a map of the Z position coordinate direction of the normal map is multiplied by a negative number to change direction.

In practice, the input information for the image material function may be determined based on the visual effect. Taking a texture mapping of a target object as an example, specifically, determining texture repetition degree data corresponding to the texture mapping based on a visual effect to be used as input information of a texture size node corresponding to the texture mapping when a world consistent texture function corresponding to a texture thematic map is obtained; and/or determining a fusion transition parameter value corresponding to the texture map based on the visual effect, wherein the fusion transition parameter value is used as input information of a projection transition contrast node corresponding to the texture map, and the fusion transition parameter value is data representing transition fusion between mapping textures in different position coordinate directions. And carrying out similar or same treatment on the normal map of the target object and the texture map of the target object, thereby obtaining the visual effect of the close reality of the target object.

Referring to FIG. 3, an example of texture mapping based on a graphics texture function is shown, and the same or similar processing may be applied to normal mapping. The specific processing depends on the information of each input map. Different parameters need to be obtained for different effect maps. The figure shows four nodes of the WorldAlignedTexture function, which specifically includes: TextureObject 301, which needs to input a texture object, specifically, the input may be a texture object 301-1 converted by a texture map; texturesize 302, which inputs UV repetition 302-1, which may be a texture map; WorldPosition 303, whose input may be absolute world position 303-1, whose role is to pick up absolute world position coordinates of the current terrain; the input of the ProjectionTransitionContrast 304 can be a fusion transition value 304-1 between textures in different mapping directions when mapping according to a predetermined coordinate direction, because for mapping in the three-dimensional direction of a steep slope, the joint between the textures generated in different mapping directions can be relatively hard and needs to be buffered for transition; the output tiles the mapping data 305 in a predetermined coordinate direction, which may include a plurality of selectable output directions, such as XYZ three-dimensional mapping directions, XY horizontal plane mapping directions, Z vertical plane mapping directions of the world-position coordinate system of the game. Of course, if the texture map is needed as a mask for terrain modeling (i.e., modeling of the target object), the Alpha channel of the texture may also be opened, so that the map resource is a four-channel resource.

Referring to fig. 3A, fig. 3A shows a comparison of visual effects obtained by different input information of the image texture function, which includes: adjusted pre-visual effect 301a and adjusted post-visual effect 302 a; the texture repetition degree data corresponding to the adjusted visual effect 301a is 100, and the texture repetition degree data corresponding to the adjusted visual effect 302a is 200.

And step S104, obtaining a target object for displaying in a game interface of a user side according to the first tile mapping data and the second tile mapping data.

In the step, a target object displayed in a game interface of a user end is obtained, and specifically, a texture map and a normal map of the target object represented by UV coordinate data are respectively mapped and output from a three-dimensional direction of a world position coordinate system of a game, that is, from XYZ directions, so as to obtain basic color mapping data and normal map mapping data of the target object (that is, a terrain object), and the basic color mapping data and the normal map mapping data constitute the target object displayed in the game interface of the user end. The basic color mapping data is first tile mapping data, and the normal pattern mapping data is second tile mapping data. Of course, mapping output from the XY direction (i.e., the horizontal plane of the three-dimensional world position coordinate system of the game) or from only the Z direction (i.e., the vertical plane of the three-dimensional world position coordinate system of the game) may be selected.

The target object processed by the method provided by the embodiment can be rendered into a map or a terrain and landform in a game through the display unit of the user side according to the data corresponding to the target object, and the visual effect of the target object is closer to the visual appearance of a real terrain instead of stretching in a stripe shape.

Referring to fig. 4, a visual effect of a steep slope rendered by a user side after applying the method for processing terrain data in a game provided by the embodiment is shown. In the figure, the method comprises the following steps: the steep visual appearance 401 before processing and the steep visual appearance 402 after processing can be seen that the steep visual appearance 401 before processing has obvious texture stretch and is obviously different from the real terrain, and the steep visual appearance 402 after processing is obviously closer to the visual appearance of the real terrain.

Referring to fig. 4A, a visual effect of a 110-degree slope rendered by the user side after applying the processing method of the terrain data in the game provided by the embodiment is shown, where the 110-degree slope is an angle between a ground surface line of an object (i.e., the mountain) and a horizontal plane in the game, and is 110 degrees. In the figure, the method comprises the following steps: the pre-treatment 110 degree slope visual appearance 401a, and the post-treatment 110 degree slope visual appearance 402a, it can be seen that the post-treatment 110 degree slope visual appearance 402a has little texture stretch and a more natural visual appearance effect than the pre-treatment 110 degree slope visual appearance 401 a.

The method for processing the topographic data in the game provided by the embodiment of the application can be executed at a user side and also can be executed at a server side.

In the embodiment executed by the user terminal, the device implemented according to the processing method of the topographic data in the game can be stored in the user terminal 101.

The processor 101-3 loads the program and the function module in the memory 101-1, and executes various function applications and data processing corresponding to the processing device 101-2 of the topographic data in the game. The display unit 101-4 renders the visual appearance of the terrain data in the game to be shown as a map or a terrain feature in the game according to various functional applications and data processing corresponding to the processing device 101-2 of the terrain data in the game at the user terminal 101. The method is used for the user side; the method further comprises the following steps: rendering the target object in a game interface of the user terminal. Specifically, the map or the terrain and the landform in the game can be rendered through the display unit of the user side according to the data corresponding to the target object, and the visual effect of the map or the terrain and the landform is closer to the real terrain instead of stretching in a stripe shape.
