Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only preferred embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A terrain generating method based on a UE engine comprises the following steps:

s1, generating a program terrain by using a Voxel technology, wherein the program terrain generates an infinite terrain in real time in a UE engine or a game mode independently generated by the UE engine; the Voxel technology is a Voxel-based algorithm, which includes automatic filling of voxels at the boundary or bottom, so that when the boundary is found, its boundary expands infinitely due to the automatic filling, thus forming an infinite terrain. Voxel is an abbreviation of Volume Pixel, which is a Voxel, for short Voxel. Voxel is a basic unit or minimum unit of image information defining a point in three-dimensional space.

S2, importing one or more pictures with any size from the outside, defining the first picture as the material of the terrain by default, and automatically defining other pictures as the pictures of the inkjet brush if other pictures exist. The externally imported pictures comprise picture imports stored in a hard disk of a user or picture imports searched from a network. In a preferred embodiment, referring to the lower right corner of fig. 1, each picture imported from the outside is displayed in real time in a texture map repository on the software control panel.

And each picture imported from the outside is automatically numbered according to the imported sequence, and a picture name with a corresponding sequence number is generated. Of course the sequence number may be modified.

And automatically forming an inkjet brush mapping by each picture imported from the outside, automatically unifying the specification and size of the picture, and automatically copying and storing the picture in a custom folder or storing the picture in a folder of a relative path of a game mode by default. Therefore, the collection and management of the pictures by the user are facilitated. And the used picture can not be lost by developing and generating the automatic copying function.

S3, developing and generating a game terrain editing interface, referring to the editing interface shown in FIG. 1, editing infinite terrain through the editing interface, wherein the editing interface comprises a brush type, an editing mode, a mixed layer, a material number, brush adaptation, brush depth, brush strength, brush radius and a brush mode, the editing mode comprises terrain carving, terrain leveling and terrain spraying, and any one or more than two editing modes can be selected to edit on infinite terrain;

the algorithm principle of carving the terrain is that an editing range is limited through a brush, the translation depth of the terrain is determined according to the strength of acting force applied by a mouse and the moving direction, and the original terrain sinks or rises. It is essentially a function of the topographic voxel ordering. The brush itself is a voxel brush generated by the program. Based on the similar principle, algorithms for leveling terrain and spraying terrain can be set, so that the algorithms can be used for editing in an editing interface.

For example, as a specific embodiment, an editing mode for carving a terrain is used, and then an infinite concave effect of the terrain can be operated by a mouse, and the bottom is continuously closed. The concave terrain can then generate interaction and collision effects with externally introduced physical and dynamic articles such as water fluid, cloth, ropes, flexible particles and the like. Referring to fig. 2, fig. 2 illustrates a concave terrain effect.

As another specific implementation, the editing mode of carving the terrain and the editing mode of spraying the terrain may be used successively, or the editing mode of carving the terrain and the editing mode of spraying the terrain may be used simultaneously. Figure 3 shows another dimpled topographical effect.

As a third embodiment, the terrace effect shown in fig. 4 can be created by using the editing mode for carving the terrain.

And S4, storing the edited terrain including scenes and/or the edited terrain or scene not including scenes in a certain folder or a folder of a relative path of the game mode, wherein the format is sav, vox or a self-defined suffix name. Namely, the method of the invention has two storage modes, one is the storage of a pure infinite terrain, and the other is the storage of a terrain including scenes, and the storage can be placed in two different files of the relative path of the game mode.

The embodiment can also comprise S5, in the game mode independently generated by the UE engine or the UE engine, the saved terrain is imported to continue editing. In this way, repeated editing and reuse of the wireless terrain can be achieved until satisfactory work is made.

The method is developed by the inventor, and the method comprises the step of developing a game terrain editing interface and the like, which are obtained after creative labor of the inventor.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
