For example, the local terminal device may include a display screen for presenting a graphical user interface including game visuals, and a processor for running the game, generating the graphical user interface, and controlling the 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 will be described in detail below by taking a terminal device as an example of a local terminal device.
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 respective positions.
In an exemplary embodiment of the present disclosure, the scene map is a game map included in a game scene in a game, in which all positions in the game are included, each position corresponding to a set of map content data. The locations in the scene map may be represented in coordinates or in labels, which are not particularly limited by the present disclosure. The map content data corresponding to each location represents a map state at that location.
In an exemplary embodiment of the present disclosure, the kind of the map content data may include at least one of relief height data, relief texture data, river region 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 each position. 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 index in the map configuration table.
For example, the map configuration table may be stored in a database in the form of a table in which all the positions in the scene map are stored, and the positions may be arranged in the order in the scene map. The map configuration table also stores map content data corresponding to each position, and one position in the map configuration table may correspond to one kind of map content data or may correspond to a plurality of kinds of map content data, which is not particularly limited in 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 include a plurality of positions in the scene map and map content data of a target category corresponding to each position, respectively. Wherein the map content data may include two or more kinds of map content data. The map content data of the target category corresponding to each position in the two or more sub map layout tables may be set according to the actual situation, for example, the map content data of the same importance level among the plurality of categories of data may be stored in the same sub map layout table according to the importance of each category of data included in the map content data. Of course, different sub map configuration tables may be configured according to the sizes of the data amounts of different kinds of data, which is not particularly limited in the present disclosure.
For example, the map configuration table includes four sub-map configuration tables, including 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 relief height data, the second sub-map configuration table is used for configuring relief 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, two or three sub-map configuration tables may be further included in the map configuration table, and two, three or more kinds of map content data may be further included in each sub-map configuration table, which is not particularly limited in the present 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 therein. For example, the map configuration table includes a sub-map configuration table including relief 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, including a first sub-map configuration table and a second sub-map configuration table. The first sub-map configuration table may include relief 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 include only the relief height data or only the relief texture data, and the second map configuration table may include only the river region data or the building model data, which is not particularly limited in the present disclosure.
In step S120, according to a first scene area captured by the virtual camera in the scene map, loading more than two preset map base units, and stitching the more than two map base units in the first scene area to obtain a first stitched map.
In the exemplary embodiment of the present disclosure, the virtual camera is a special object in the game engine, which can be placed at any corner in the game scene, or the game scene captured in the scene map according to the parameters of the adjustment virtual camera can be the first scene area by changing the position, rotation angle, jing Bie, projection, and other parameters of the virtual camera and acquiring the desired game scene.
In an exemplary embodiment of the present disclosure, the preset map base unit includes a preset number of patch models, where the patch models may be blank planes, map content data on the blank planes are all 0, and the size of the blank planes may be set according to actual situations, and the smaller the blank planes, the higher the accuracy of the obtained target scene map, 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 contrast is not particularly limited. For example, fig. 2 shows a schematic structure of a preset map base unit, and as shown in fig. 2, the preset map base 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 in a scene map by a virtual camera specifically includes: according to the size of the first scene area captured in the scene map by the virtual camera and the size of the preset map base unit 200, the target number of the preset map base unit 200 to be loaded is determined, and the map base unit 200 of the target number is loaded.
The target number of map base units 200 is loaded according to the size of the first scene area and the size of the map base units 200, 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 base unit 200 is (10, 10), the target number of map base units 200 to be loaded is 5*5 map base units 200.
In the exemplary embodiment of the present disclosure, a preset number of map base units 200, which may be set according to actual conditions, are stored in the cache pool. The preset number of map base units 200 in the buffer pool may be determined according to the size of the maximum scene area captured by the virtual camera, for example, the maximum scene area captured by the virtual camera under a certain viewing angle 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 base units 200 that can be accommodated in the cache pool, for example, 50×50 map base units 200 may be used, or 100×100 map base units 200 may be used, which is not limited in this disclosure.
For example, fig. 3 shows a schematic diagram of a first scene area captured by a virtual camera, as shown in fig. 3, the map base unit 200 is constructed according to a space coordinate system 302, and the patches of the map base unit 200 are parallel to the xoy plane, and assuming that the virtual camera looks at the scene map at a certain angle, a plane where the map base unit 200 is located and a view cone 301 of the virtual camera intersect to obtain a quadrilateral plane, four vertexes of the quadrilateral plane are (lb, rb, rt, lt), and the quadrilateral plane is a range of the scene area that the virtual camera can capture, and a preset number of map base units 200 required to fill the first scene area can be calculated according to the range size of the quadrilateral plane and the size of the map base unit 200, that is, the preset number of map base units 200 need to be loaded.
In an 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, the stitching of more than two 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 with the loaded target number are spliced in the first scene area in sequence to obtain a first spliced map.
The spatial coordinate system 302 is established according to the starting point of the entire scene map in the game as the origin, where the starting point of the scene map may be the point with the largest position coordinate in the scene map or the point with the smallest position coordinate in the scene map, which is not specifically limited in the present disclosure. Of course, the spatial coordinate system 302 may be established according to the vertex of the first scene area as the origin, and the vertex of the first scene area may be the point with the smallest position coordinate or the point with the largest position coordinate in the first scene area, which is not specifically limited in the present disclosure.
In addition, as shown in fig. 3, the spatial coordinate system 302 may be a three-dimensional cartesian coordinate system, and the planes of the x-axis and the y-axis of the spatial coordinate system 302 may be used to represent the plane size of the first scene area, and the z-axis of the spatial coordinate system 302 may be used to represent the topography of the first scene area.
Taking the point with the smallest position coordinate in the first scene area as the origin, the present disclosure takes the space coordinate system 302 as an example, starting from the origin of the space coordinate system 302, starting to progressively lay the map base unit 200 along the x-axis of the space coordinate system 302 until the x-axis in the first scene area is full, starting to progressively lay the map base unit 200 along the y-axis of the space coordinate system 302 until the entire first scene area is full by the map base unit 200. The map base unit 200 may also be incrementally deposited along the y-axis and then incrementally deposited along the x-axis within the first scene area, as this disclosure is not particularly limited.
Of course, the plane in which the y-axis and the z-axis of the spatial coordinate system 302 are located 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 topography of the first scene area. The present disclosure is not particularly limited thereto.
In an exemplary embodiment of the present disclosure, after the splicing of two or more map base units 200 in the first scene area to obtain the first spliced map, the position of each map base unit 200 in the first spliced map in the scene map is obtained.
In step S130, map content data corresponding to each map base unit 200 in the first stitched map is obtained from the map configuration table according to the position of each map base unit 200 in the first stitched map in the scene map.
In an exemplary embodiment of the present disclosure, map content data corresponding to each map base unit 200 is searched in a map configuration table according to the position of each map base unit 200 in a scene map, i.e., one or more of relief height data, relief texture data, river region data, or building model data on each map base unit 200 in a first spliced map is acquired.
In step S140, the map content data corresponding to each map base unit 200 in the first stitched map is loaded into the corresponding map base unit 200, respectively, 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 first stitched map after rendering is displayed on the graphical user interface as the first target scene map.
