Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used in the embodiments of the present application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
In most games, the terrain-playing important role, such as sandbox game, strategy game and numerous role-playing games, the map belonging to the game is elaborated, and then the game scene is arranged based on the map, with the addition of animals, plants, monsters, buildings and characters, so that the terrain-making tool can be an indispensable component of modern game engines.
Currently, the illusion Engine 4 (UE 4) is an excellent and popular 3D game Engine and development tool, which supports the development of 3D games from 2D mobile platform games to computers to game host platforms. The UE4 provides development tool downloading of Windows and Mac platforms, and the manufactured works can run on Windows, Mac, Linux, PS4, X-Box One, iOS, Android and even HTML5 and other platforms.
In the existing scene terrain manufacturing method, terrain construction is usually directly performed in the landscape by a brush tool in the UE4, or a height map is manufactured by third-party software and then led into the UE4, and a corresponding terrain is obtained through the landscape, and then a corresponding terrain is obtained through the height map by using a common static model through replacement.
However, the terrain model obtained by replacing the common static model is mainly processed by the shader on the vertex position of the model, and a real solid terrain model is not created, so that the physical attributes of the new model obtained by replacing, such as a collision physical form and the like, are still generated based on the original model, the original physical attributes are not really changed, and the correct physical collision physical form is difficult to generate. If the character still recognizes the collision form of the original model when walking on the replacement model, and vegetation is generated based on the collision form of the original model when vegetation is spread on the replacement model, there is a penetration phenomenon.
In order to solve the above technical problem, an embodiment of the present application provides a terrain construction method, in which a solid terrain model corresponding to a terrain to be constructed can be generated by reading grayscale bitmap information of a height map and according to vertex information determined by the grayscale bitmap information, and a correct physical collision shape matched with the solid terrain model can be created based on the generated solid terrain model. The following examples are given for the purpose of illustration.
Referring to fig. 1, fig. 1 is a schematic flow chart of a terrain building method provided in an embodiment of the present application. The terrain construction method comprises the following steps:
S101, obtaining a height map of a terrain to be constructed.
In a possible implementation manner, when the terrain is constructed, a height map of the terrain to be constructed is obtained, wherein the height map of the terrain to be constructed can be obtained through various map services, can be pre-drawn by using various graphic software, and can be manufactured by using noise textures.
The height map may be understood as a set of consecutive arrays, where the elements in the array correspond to vertices in the terrain mesh one-to-one, and each element specifies a height value of a vertex of the terrain mesh.
The height map is usually implemented by using a gray scale map, in which the greater the brightness, the higher the terrain height.
For better understanding of the embodiments of the present application, exemplary, refer to fig. 2, and fig. 2 is a height view provided in the embodiments of the present application.
In a game environment, terrains such as hills, valleys, flat lands, cliffs and the like in real life can be simulated by using the height map.
And S102, reading the gray bitmap information of the height map, and determining the vertex information of the terrain to be constructed according to the gray bitmap information.
In the embodiment of the application, after the height map of the terrain to be constructed is obtained, the gray bitmap information of the height map is read, and the vertex information of the terrain to be constructed is determined according to the read gray bitmap information.
In one possible embodiment, the user may first specify the methods and classes required to generate the terrain model in the UE4, such as the component "uprocedurearameshcomponent". In addition, the functions and related parameters required for generating the model are found in advance from the official document API of the UE 4. For example:
an index of the part that needs to be created or replaced; a vertex buffer for all vertex positions of the mesh portion; indicating which vertices make up the index buffer for each triangle, the length must be a multiple of 3; an optional array of normal vectors for each vertex, if provided, must be the same length as the Vertics array; an optional array of texture coordinates for each vertex, if provided, must be the same length as the Vertics array; the optional color array for each vertex, if provided, must be the same length as the Vertics array; an optional array of tangent vectors for each vertex, if provided, must be the same length as the Vertics array; indicating whether a collision should be created for this part.
For example, the UE4 may create an actor named heighLand. Adding a program modeling component 'proceduremoponent' in the newly-built actor. A variable inheriting the 'procedureponent' class is created in the header file, so that the related method and attribute of the 'procedureponent' component can be used.
And S103, generating a terrain model corresponding to the terrain to be constructed according to the vertex information.
In the embodiment of the application, after the vertex information of the terrain to be constructed is determined, model parameters required by the terrain model such as a terrain normal, a terrain tangent, UV coordinates and triangular surfaces are generated according to the vertex information of the terrain to be constructed, and then the terrain model corresponding to the terrain to be constructed can be generated according to the generated model parameters.
After a terrain model corresponding to the terrain to be constructed is generated, a physical collision body matched with the terrain model can be created based on the generated terrain model, and relevant physical calculation is carried out on the replaced terrain model.
For better understanding of the embodiments of the present application, exemplarily, refer to fig. 3 and 4, and fig. 3 is a schematic view of a terrain provided in the embodiments of the present application; fig. 4 is a schematic view of a terrain model provided in an embodiment of the present application.
According to the terrain construction method provided by the embodiment of the application, the gray level bitmap information of the height map is read, and the entity terrain model corresponding to the terrain to be constructed can be generated according to the vertex information determined by the gray level bitmap information, so that the correct physical collision body matched with the entity terrain model can be created based on the generated entity terrain model.
Based on the content described in the foregoing embodiments, in a possible implementation manner of the present application, after the model parameters of the terrain to be constructed are generated, a program modeling component "procedurepoponent" in the UE4 may be called, and then, based on the model parameters of the terrain to be constructed, a terrain model corresponding to the terrain to be constructed is generated.
In one possible embodiment of the present application, after generating the terrain model, the method further includes:
and setting the size of the generated grid, and adjusting the size proportion of the terrain model according to the model frame of the generated terrain model.
Specifically, the size of a model frame of the generated terrain model is read firstly, such as length, width, height and the like; and calculating a ratio of the size of the model frame to the pixel size in the grayscale bitmap information, and adjusting the size ratio of the terrain model according to the calculated ratio and a setworld scale3D function.
In another possible embodiment of the present application, after generating the terrain model, the method further includes:
and optimizing the terrain model by adopting a preset optimization mode.
The optimization mode comprises a FrontAndBack optimization mode and an AxesAlternately optimization mode, wherein the AxesAlternately optimization mode adopts two channels, and optimization is performed along a Y axis and then along an X axis; the frontbackup optimization approach uses a single channel, optimized along either the X-axis or the Y-axis, with the latter optimized along the X-axis if the former was optimized along the Y-axis.
In the plan view of a terrain, the vertical axis is the Z axis, the horizontal axis is the X axis, and the vertical axis is the Y axis.
In addition, in the embodiment of the present application, the sampling frequency may also be optimized at the same time, for example, the sampling frequency is reduced by 2 times or 4 times.
The terrain construction method provided by the embodiment of the application solves the technical problem that in the existing UE4, a terrain model generated by performing replacement operation in materials by using a height map is not a real entity model, so that the physical collision physical form is incorrect. By utilizing the terrain construction method provided by the embodiment of the application, the terrain manufacturing efficiency of terrain manufacturers taking the UE4 as a production tool can be greatly improved, and meanwhile, as the generated terrain model is a static model, richer terrain effects can be manufactured through instantiation, and the overall project performance is optimized.
