In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the disclosure.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
In the related art in the field, the scene area is mainly loaded in blocks. The block loading scene area is specifically a scene area which is obtained by dividing a map into a plurality of block areas according to different space areas in a game scene and only can be seen by a virtual camera in the game when the game is loaded. However, the technique of loading scene areas in blocks has the disadvantages that the whole game scene needs to be made in advance by art workers, and the modification process of the game scene is complex.
Based on the problems in the related art, in an embodiment of the present disclosure, a method for generating a scene map is provided, where the method for generating a scene map may be applied to generation of a game scene and generation of a realistic image. The embodiment of the present disclosure is explained by taking a game scene map as an example, fig. 1 shows a flow diagram of a method for generating a scene map, and as shown in fig. 1, the method for generating a scene map at least includes the following steps:
step S110: acquiring a map configuration table, wherein the map configuration table comprises a plurality of positions of a scene map and map content data corresponding to the positions;

step S140: and respectively loading the map content data corresponding to each map basic unit in the first spliced map into the corresponding map basic units so as to obtain a first target scene map for display.
According to the method for generating the scene map, on one hand, the target scene map can be generated according to the map configuration table and the map basic unit, the loading time of the target scene map is shortened, the memory occupied by the target scene map is reduced, and the system loss is saved; on the other hand, the target scene map can be rendered according to the map configuration table, so that the target scene map can be changed according to the change of the map content data in the map configuration table, the flexible modification of the target scene map can be realized, the workload of map makers is reduced, and the generation efficiency of the target scene map is improved; on the other hand, dynamic switching of the target scene map can be achieved according to the capturing range of the virtual camera.
The method for generating the scene map in the embodiment of the present disclosure may be executed in a terminal device or a server. The terminal device may be a local terminal device. When the data processing method is operated on the server, the data processing method can be a cloud game.
In an alternative embodiment, cloud gaming refers to a cloud computing-based gaming mode. In the running mode of the cloud game, the running main body of the game program and the game picture presenting main body are separated, the storage and the running of the generation method of the scene map are completed on the cloud game server, and the cloud game client is used for receiving and sending data and presenting the game picture, for example, the cloud game client can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; however, the terminal device performing the game data processing is a cloud game server in the cloud. When a game is played, a player operates the cloud game client to send an operation instruction to the cloud game server, the cloud game server runs the game according to the operation instruction, data such as game pictures and the like are encoded and compressed, the data are returned to the cloud game client through a network, and finally the data are decoded through the cloud game client and the game pictures are output.
In an alternative embodiment, the terminal device may be a local terminal device. The local terminal device stores a game program and is used for presenting a game screen. The local terminal device is used for interacting with the player through a graphical user interface, namely, a game program is downloaded and installed and operated through an electronic device conventionally. The manner in which the local terminal device provides the graphical user interface to the player may include a variety of ways, for example, it may be rendered for display on a display screen of the terminal or provided to the player through holographic projection. For example, the local terminal device may include a display screen for presenting a graphical user interface including a game screen and a processor for running the game, generating the graphical user interface, and controlling display of the graphical user interface on the display screen.
In order to make the technical solution of the present disclosure clearer, a method for generating a scene map in the present exemplary embodiment is described in detail below by taking a terminal device as a local terminal device as an example.
In step S110, a map configuration table is acquired, wherein the map configuration table includes a plurality of positions of a scene map and map content data corresponding to the positions.
In an exemplary embodiment of the present disclosure, the scene map is a game map included in a game scene in the game, in which all positions in the game are included, and each position corresponds to a set of map content data. The position in the scene map may be represented in a coordinate form or a reference number form, which is not specifically limited by the present disclosure. The corresponding map content data at each location represents the map state at that location.
In an exemplary embodiment of the present disclosure, the category of the map content data may include at least one of terrain height data, relief texture data, river area data, or building model data, which is not particularly limited by the present disclosure.
In an exemplary embodiment of the present disclosure, the map configuration table includes a plurality of positions in the scene map, and further includes map content data corresponding to the respective positions. That is, each position in the scene map can find the map content data corresponding to the position according to the position coordinates or the position label in the map configuration table.
For example, the map configuration table may be stored in a database in a table form, and all the positions in the scene map are stored in the map configuration table, and the positions may be arranged in an order in the scene map. The map configuration table further stores map content data corresponding to each location, and one location in the map configuration table may correspond to one kind of map content data or to a plurality of kinds of map content data, which is not particularly limited by the present disclosure.
In an exemplary embodiment of the present disclosure, the map configuration table may include two or more sub-map configuration tables, and the two or more sub-map configuration tables may respectively include a plurality of locations in the scene map and map content data of the target category corresponding to the respective locations. Wherein the map content data may include more than two kinds of map content data. The map content data of the target type corresponding to each position in the two or more sub-map arrangement tables may be set according to actual conditions, for example, the map content data may be set according to the importance of each type of data included in the map content data, and the map content data of the same importance level among the plurality of types of data may be stored in the same sub-map arrangement table. Of course, different sub-map configuration tables may be configured according to the size of the data volume of different types of data, which is not specifically limited by the present disclosure.
For example, the map configuration table includes four sub-map configuration tables, which respectively include a first sub-map configuration table, a second sub-map configuration table, a third sub-map configuration table, and a fourth sub-map configuration table. The first sub-map configuration table is used for configuring terrain height data, the second sub-map configuration table is used for configuring landform texture data, the third sub-map configuration table is used for configuring river region data, and the fourth sub-map configuration table is used for configuring building model data. Of course, the map configuration table may further include two or three sub-map configuration tables, and each sub-map configuration table may further include two, three or more types of map content data, which is not particularly limited in this disclosure.
In addition, the map configuration table may further include one or two sub-map configuration tables, and each sub-map configuration table may include one or more kinds of map content data. For example, the map configuration table includes a sub-map configuration table, and the sub-map configuration table includes terrain height data, relief texture data, river region data, or building model data. For another example, the map configuration table includes two sub-map configuration tables, which respectively include a first sub-map configuration table and a second sub-map configuration table. The first sub-map configuration table may include terrain height data and relief texture data, and the second sub-map configuration table may include river region data and building model data. Of course, the first map configuration table may also include only terrain height data or only landform texture data, and the second map configuration table may also include only river region data or building model data, which is not specifically limited by the present disclosure.
In step S120, two or more preset map base units are loaded according to a first scene area captured by the virtual camera in the scene map, and the two or more map base units are spliced in the first scene area to obtain a first spliced map.
In an exemplary embodiment of the present disclosure, in the game engine, the virtual camera is a special object, which can be placed at any corner in the game scene, and can also be used to acquire the desired game scene by changing the position, rotation angle, view, projection and other parameters of the virtual camera, and the game scene captured in the scene map according to the parameters of the virtual camera is adjusted to be the first scene area.
In an exemplary embodiment of the present disclosure, the preset map base unit includes a preset number of patch models, each patch model may be a blank plane, the map content data on each blank plane is 0, and the size of each blank plane may be set according to an actual situation, where the smaller the blank plane is, the higher the accuracy of the obtained target scene map is, and the more details are presented. The preset number can be set according to actual conditions, and the larger the preset number is, the higher the accuracy of the obtained target scene map is, and the more details are presented on the target scene map. The present disclosure is not particularly limited. For example, fig. 2 shows a schematic structural diagram of a preset map basic unit, and as shown in fig. 2, the preset map basic unit 200 is composed of 3 × 3 patch models 201.
In an exemplary embodiment of the present disclosure, loading more than two preset map base units 200 according to a first scene area captured by a virtual camera in a scene map specifically includes: determining the number of targets of the preset map basic unit 200 to be loaded according to the size of the first scene area captured by the virtual camera in the scene map and the size of the preset map basic unit 200, and loading the map basic units 200 of the number of targets.
For example, if the range size of the first scene area captured by the virtual camera is (50, 50) to (100 ), and the range size of each map basic unit 200 is (10, 10), the target number of the map basic units 200 to be loaded is 5 × 5 map basic units 200.
In an exemplary embodiment of the present disclosure, a preset number of map base units 200 are stored in the cache pool, and the preset number may be set according to actual situations. The preset number of the map base units 200 in the cache pool may be determined according to the size of the maximum scene area captured by the virtual camera, for example, the scene area captured by the virtual camera under a certain viewing angle is the largest, the maximum scene area captured by the virtual camera is obtained, and the preset number is determined according to the size of the maximum scene area and the size of the map base units 200. Of course, the preset number may also be determined according to the number of the maximum number of map basic units 200 that can be accommodated in the cache pool, for example, 50 × 50 map basic units 200 may be used, or 100 × 100 map basic units 200 may be used, which is not specifically limited in this disclosure.
For example, fig. 3 shows a schematic structural diagram of a first scene area captured by a virtual camera, as shown in fig. 3, a map base unit 200 is constructed according to a spatial coordinate system 302, and a patch of the map base unit 200 is parallel to an xoy plane, assuming that the virtual camera views a scene map at a certain angle, a plane in which the map base unit 200 is located intersects with a view cone 301 of the virtual camera to obtain a quadrilateral plane, four vertices of the quadrilateral plane are (lb, rb, rt, lt), and the quadrilateral plane is a range of the scene area that can be captured by the virtual camera, and according to a range size of the quadrilateral plane and a size of the map base unit 200, a preset number of map base units 200 required to cover the first scene area can be calculated, that is, the preset number of map base units 200 need to be loaded.
In the exemplary embodiment of the present disclosure, more than two preset map base units 200 are loaded, and specifically, more than two map base units 200 may be loaded from a cache pool.
In an exemplary embodiment of the present disclosure, stitching two or more map base units 200 in a first scene area to form a first stitched map specifically includes: starting from the position of the origin of the spatial coordinate system 302 corresponding to the first scene area, the map base units 200 of the loaded target number are sequentially spliced in the first scene area to obtain a first spliced map.
The space coordinate system 302 is established by taking a starting point of the whole scene map in the game as an origin, where the starting point of the scene map may be a point with the largest position coordinate in the scene map, or may be a point with the smallest position coordinate in the scene map, and the disclosure does not specifically limit this. Of course, the spatial coordinate system 302 may also be established by using the vertex of the first scene area as the origin, and the vertex of the first scene area may be a point with the smallest position coordinate in the first scene area, or may be a point with the largest position coordinate, which is not specifically limited by the present disclosure.
In addition, as shown in fig. 3, the spatial coordinate system 302 may be a three-dimensional cartesian coordinate system, a plane in which an x-axis and a y-axis of the spatial coordinate system 302 are located may be used to represent a plane size of the first scene area, and a z-axis of the spatial coordinate system 302 may be used to represent a terrain height of the first scene area.
Taking the point with the smallest position coordinate in the first scene area as the origin to establish the spatial coordinate system 302 as an example, starting from the origin of the spatial coordinate system 302, the map base unit 200 is gradually laid along the x-axis of the spatial coordinate system 302, and after the x-axis in the first scene area is fully laid, the map base unit 200 is further gradually laid along the y-axis of the spatial coordinate system 302 until the entire first scene area is fully laid by the map base unit 200. The map base unit 200 may also be laid in the first scene area in increments along the y-axis and then along the x-axis, which is not specifically limited by the present disclosure.
Of course, the plane of the y-axis and the z-axis of the spatial coordinate system 302 may be used to represent the plane size of the first scene area, and the x-axis of the spatial coordinate system 302 may be used to represent the terrain height of the first scene area. The present disclosure does not specifically limit this.
In an exemplary embodiment of the present disclosure, after two or more map base units 200 are spliced in a first scene area to obtain a first spliced map, the positions of the map base units 200 in the first spliced map in the scene map are obtained.
In step S130, map content data corresponding to each map basic unit 200 in the first merged map is acquired from the map configuration table according to the position of each map basic unit 200 in the first merged map in the scene map.
In an exemplary embodiment of the present disclosure, according to the position of each map basic unit 200 in the scene map, map content data corresponding to each map basic unit 200 is searched in the map configuration table according to the position of each map basic unit 200 in the scene map, that is, one or more of relief height data, topographic texture data, river region data, or building model data on each map basic unit 200 in the first merged map is obtained.
In step S140, the map content data corresponding to each map base unit 200 in the first merged map is loaded into the corresponding map base unit 200, respectively, so as to obtain a first target scene map for display.
In an exemplary embodiment of the present disclosure, each map base unit 200 is rendered according to the acquired map content data corresponding to each map base unit 200, and the rendered first mosaic map is displayed on the graphical user interface as the first target scene map.
In addition, since the first target scene map is formed by splicing a plurality of map base units 200, when the terrain height data on each map base unit 200 is inconsistent, a splicing crack may occur at the splicing edge of each map base unit 200. At this time, the crack at the spliced edge needs to be processed, for example, the terrain height data on the two map base units 200 with the edge crack may be obtained, the average height of the two terrain height data at the edge may be calculated, and the terrain height data of the two map base units 200 at the edge crack may be modified into the average height.
