The above map location is: the location of the map data to be loaded in the scene map. For example, the location of the game character on the game map.

In one embodiment of the present application, when obtaining the map position, the position selected by the user through an external input device such as a mouse or a touch screen can be obtained as the map position to be loaded with data, or the position input by the user through an external input device can be obtained Information, based on the above location information to determine the map location to be loaded with data, the above location information may be location coordinates, location identification, etc.

In one embodiment of the present application, in the case where the above-mentioned scene map is a game map, the position where the current game character is located can be obtained as the map position to be loaded with data.

S102. Determine a region to be loaded including a map location in the scene map.

Specifically, the above-mentioned map position may be used as a mark position, and an area within a preset range in the scene map may be determined as the area to be loaded.

For example, assuming that the above-mentioned map position is where the current game character is located, the mark position is the center position, and the preset range is: a circular range with a radius of 5 kilometers, then the above-mentioned area to be loaded can be: in the scene map, the current game character The location is the central location and the area within a radius of 5 kilometers.

S103. Obtain a target data block used to describe the area to be loaded from map data blocks of different resolution levels.

Wherein, the above-mentioned map data block may be used to describe the terrain information of the area in the scene map, such as the height, geology and other information of the area.

The resolution level of each map data block is used to reflect: the detail richness of the area described by the map data block. As the resolution level increases, the range of the area described by a map data block decreases and the detail richness increases The area described by a map data block at a resolution level includes: the area described by at least two map data blocks at a next resolution level.

The map data block with a higher resolution level, the smaller the range of the described area, and the higher the detail richness of the described area; the lower the resolution level of the map data block, the smaller the range of the described area The larger and the less detailed the area described.

In the case that the region described by the map data block has a higher level of detail, it can be understood that the resolution of the map data block is higher.

The lowest resolution level includes at least one map data block, and the area described by the map data block of each resolution level may include the area described by at least two map data blocks in a higher resolution level. Different map data blocks describe different areas.

The area described by a map data block of a resolution level includes: the area described by at least two map data blocks of the next resolution level; and the target data block is loaded. In this way, when the map data is loaded, the map data blocks used to describe the area to be loaded can be selected for loading, and there is no need to load map data blocks unrelated to the area to be loaded, thereby reducing the data volume of the loaded map data. It can be seen that, by applying the solutions provided by the above embodiments, the loading speed of map data can be improved.

Specifically, the terrain of the area to be loaded may be loaded, and then a configuration model consistent with the type information of the scene configuration may be obtained. Then, according to the above-mentioned distribution information, the obtained configuration model is loaded on the terrain, so that the loaded scene includes the above-mentioned scene configuration.

For example, it is assumed that the type information of the above-mentioned scene configuration indicates that the scene is configured as vegetation, and the distribution information indicates that the above-mentioned vegetation is distributed around the edge area of the scene. Then the terrain can be loaded according to the terrain information to obtain the vegetation model corresponding to the vegetation, and then the above vegetation model can be loaded in the edge area around the terrain, making the loaded scene more abundant.

In the above solution, on the one hand, the loaded data includes terrain data and data related to scene configuration, and the loaded data is richer, which can increase the richness of the scene obtained after loading. On the other hand, the map data block only contains the type information and distribution information of the scene configuration, and does not need to contain a specific scene configuration model, which can reduce the data volume of the map data block and improve the map data loading speed.
