Referring to fig. 1, a flowchart illustrating steps of a method for processing a virtual terrain according to an embodiment of the present invention is shown, where a graphical user interface is provided by a terminal device, where the graphical user interface includes a virtual terrain, and the method may specifically include the following steps:
the virtual terrain refers to a ground surface or a ground system generated in a data processing system, describes information such as river valleys and vegetation rocks, and can be made by various DCC software by a user, as shown in FIG. 2. The first virtual terrain includes a plurality of divided terrain areas, and each terrain area has the same size. The user can modify the virtual terrain in the game engine, and the terrain area changed by the modification in the virtual terrain is determined as the target area.
the virtual terrain can be reconstructed by baking, and the terrain area modified by the user is determined as the area to be baked.
And 103, baking the target area of the virtual terrain again according to the read changed terrain file of the virtual terrain to obtain the virtual terrain including the target area after baking again.
The virtual terrain has a corresponding terrain file, the terrain file contains terrain data of the virtual terrain, and the game engine can construct the corresponding virtual terrain according to the terrain data contained in the terrain file. The game engine can bake the target area in the virtual terrain again according to the read terrain file of the changed virtual terrain, and obtain the virtual terrain including the baked target area.
In the embodiment of the invention, when the virtual terrain is changed, the terrain area which is changed in the virtual terrain is determined as the target area, the virtual terrain comprises a plurality of terrain areas, the target area is determined to be an area to be baked again, and the target area of the virtual terrain is baked again according to the read terrain file of the changed virtual terrain to obtain the virtual terrain comprising the target area baked again. After the user changes the virtual terrain, the game engine can only read the changed part in the virtual terrain to generate the changed virtual terrain without completely replacing the whole virtual terrain, and the time consumed by the user for waiting for baking the terrain is greatly reduced.
Referring to fig. 3, a flowchart illustrating steps of another virtual terrain processing method provided in an embodiment of the present invention is shown, and a graphical user interface is provided by a terminal device, where the graphical user interface includes a virtual terrain, and the method specifically includes the following steps:
the user leads the terrain file of the virtual terrain into the game engine from the DCC software, backups the terrain file in the project file and simultaneously leads the file path of the terrain file into the game engine. When the user reads the terrain file again in the game engine, the read terrain file is compared with the terrain file stored in the project file.
the user may modify the terrain file in the game engine to change the virtual terrain. And when the game engine judges that the modified terrain file is different from the initial terrain file, determining that the virtual terrain is changed.
when the game engine judges that the imported terrain file is changed, namely the virtual terrain is changed, the changed area in the virtual terrain is determined as the target area, a plurality of terrain areas in the virtual terrain are obtained by geometric partitioning, after the virtual terrain is created by DCC software, the user can input the segmentation parameters, the terminal performs geometric partitioning on the virtual terrain according to the actual requirements according to the segmentation parameters, for example, 2 x 2, 4 x 4, etc., as shown in fig. 4 and 5, fig. 4 shows a virtual terrain divided by 2 x 2 in DCC software, 301 and 304 respectively represent different terrain areas after division, and fig. 5 shows the display effect of the divided virtual terrain after the divided virtual terrain is imported into the game engine, and the imported virtual terrain is also divided into 2 × 2 terrain areas 401 and 404 with equal size. The segmentation is carried out by equal ratio segmentation, so that the size of each cut terrain area is still 2 times, such as 1024 by 1024, and the requirements of the game engine on the terrain are met.
and determining the area which is confirmed as the target area in the virtual terrain as the area to be baked again.
in a preferred embodiment of the present invention, the topography file of the virtual topography includes topography files corresponding to respective topography areas of the virtual topography, and the target area of the virtual topography is baked again according to the read altered topography file of the virtual topography, further including the following sub-steps:
and according to the read terrain file corresponding to the target area after the change, baking the target area of the virtual terrain again.
And the game engine re-bakes the target area according to the read changed terrain file, so as to reconstruct the target area of the virtual terrain.
the height map is a rasterized image in which surface height data is stored for each pixel. By baking the region to be baked, a height map corresponding to the target region can be generated.
After the virtual terrain containing the redried target area is obtained, the virtual terrain containing the redried target area is displayed in a game engine.
In a preferred embodiment of the present invention, the step 207 further comprises the following sub-steps:
displaying the virtual terrain containing the target area after re-baking according to the height map.
The game engine displays the virtual terrain including the changed target area according to the height map of the target area.
In the embodiment of the invention, a terrain file of a virtual terrain is read from a preset path, the read terrain file is compared with an initial terrain file of the virtual terrain stored in a project file, if the read terrain file is different from the initial terrain file of the virtual terrain, the virtual terrain is determined to be changed, when the virtual terrain is changed, a terrain area changed in the virtual terrain is determined as a target area, the virtual terrain comprises a plurality of terrain areas, the target area is determined to be an area to be baked again, the target area of the virtual terrain is baked again according to the read terrain file of the virtual terrain after being changed, the virtual terrain comprising the target area after being baked again is obtained, a corresponding height map is generated according to the virtual terrain comprising the target area after being baked again, and the virtual terrain comprising the target area after being baked again is displayed, when the user modifies the virtual terrain, data corresponding to the virtual terrain does not need to be repeatedly imported and exported, the game engine only needs to read the part of the virtual terrain modified by the user, and the modified part of the virtual terrain can be automatically baked and displayed, so that the operation steps are simplified, and the time for the user to wait for baking is saved.
In order to enable a person skilled in the art to better understand the solution of the present invention, the present application is exemplified below by way of example, but it should be understood that the present application is not limited thereto.
After the user finishes making the virtual terrain, the user inputs the dividing parameters according to the requirement of the user, and divides the virtual terrain into 2 multiplied by 2 virtual terrains, namely 4 terrain areas are included.
And then the user leads the terrain file corresponding to the virtual terrain into the game engine, backups the terrain file in the project file and generates the virtual terrain in the game scene. Since the virtual terrain is divided into 4 terrain areas, the virtual terrain generated in the game engine is also composed of 4 terrain areas.
In order to improve the effect of the virtual terrain, the user modifies the virtual terrain, as shown in fig. 6, a shaded part 501 is a part needing to be modified, and the part is seen to be low in terrain and the user wants to pull up the terrain. While the modified effect is shown in fig. 7, the shaded portion 601 is the modified effect. Since there are not many portions to be modified, the modified terrain area occupies only one of the entire virtual terrain, as shown in fig. 8, 701 is the virtual terrain, and 702 is the modified portion.
After the modification is completed, the game engine compares the read terrain file, namely the modified terrain file, with the initial terrain file in the backup, determines a terrain area to which the modified part belongs according to the modified position, cures the terrain area, and keeps other terrain areas as they are.
After the baking is finished, a corresponding new height map is generated for the target area, and the game engine reads the new height map, so that the modified target area in the virtual terrain can be displayed, as shown in fig. 9, 801 is the target area displayed according to the new height map, and 802 is other terrain areas in the virtual terrain.
In the whole operation process, after the terrain is changed by a user, the game engine only reads a part of terrain areas where the virtual terrain is changed, the whole virtual terrain does not need to be replaced completely, and terrain data corresponding to the exported virtual terrain does not need to be imported again, so that the tedious operation is simplified, and the time spent by the user for waiting for the baking of the terrain is greatly reduced.
