Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method and device for generating scene terrain, a storage medium, and an electronic device. Background Art

[0002] In related technologies, the production of large world maps is a key link in the production of scenes for open world games (including but not limited to first-person shooters, massively multiplayer online games, adventure exploration puzzle games and other 3D games). In recent years, the support of mobile device performance and the development of engine technology have spawned more and more open world projects.

[0003] In the related technology, the methods of making world maps include: 1. Using the map editing tools that come with the engine (such as Unity's Terrain and Unreal Engine's Landscape); 2. Using third-party software to develop terrain assets and then importing them into the game engine (such as making terrain in software such as Gaia and Houdini); 3. Using 3D software to produce basic models, splicing terrain undulations in the engine, and then baking them remotely. The corresponding defects mainly include: the map editing tools that come with the engine have low iteration efficiency, limited brush effects, and unnatural terrain undulations and erosion. The terrain effects produced by terrain assets developed by third-party software are better than those of engine tools, but artists are required to master multiple software, and the production process is repetitive and cumbersome, and the effects cannot be adjusted directly in the engine. The terrain splicing method used in the self-developed Hou Tu framework has improved on the first two items, but is limited by the types of basic models produced, and only supports upward superposition. There are no tools to lower the terrain downward, and the operation is cumbersome when making trenching terrain.

[0004] With respect to the above-mentioned problems existing in the related technologies, no effective solutions have been found so far. Summary of the invention

[0039] Optionally, the input-output device 108 further includes a human-computer interaction screen for obtaining human-computer interaction instructions through a human-computer interaction interface and for presenting images in a virtual scene;

[0040] In this embodiment, a method for generating a scene terrain is provided. Figure 2 FIG. 1 is a flow chart of a method for generating a scene terrain according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0041] Step S202, creating a first terrain model and a second terrain model on the plane geometric body;

[0042] Optionally, this embodiment can be applied to virtual scenes such as virtual game scenes, virtual teaching scenes, virtual demonstration scenes, etc., and the virtual scene includes multiple scene objects, such as terrain, buildings, etc. In this embodiment, the virtual scene is taken as an example of a virtual game scene.

[0043] Optionally, when the first terrain model and the second terrain model are created, they can be created using the same or different terrain models. The first terrain model is the terrain model to be dug down, and the second terrain model is the terrain model to be raised. What is generated is a model resource, and the resource type is mesh (grid).

[0044] Step S204: Dig down the first terrain model on the planar geometric body and raise the second terrain model to generate a terrain file for the scene terrain;

[0045] In this embodiment, for the raising, the terrain height is updated at the top of the second terrain model, and for the digging down, the terrain height is updated at the bottom of the first terrain model.

[0046] Step S206: Import the terrain file into the modeling engine, and bake the terrain detail parameters of the scene terrain locally in the modeling engine based on the terrain file to generate terrain layer data for the scene terrain.

[0047] In this embodiment, the detail parameters are the detail parameters configured or generated during the preprocessing of the scene terrain after digging down and raising, such as terrain distortion processing, surface erosion processing, and texture mapping processing.

[0048] Through the above steps, the first terrain model and the second terrain model are created on the planar geometric body; the first terrain model is dug down on the planar geometric body and the second terrain model is raised to generate a terrain file for the scene terrain; the terrain file is imported into the modeling engine, and the terrain detail parameters of the scene terrain are baked locally in the modeling engine based on the terrain file to generate terrain layer data for the scene terrain. By generating a terrain file for the scene terrain with the dug-down and raised terrain models and baking the terrain detail parameters in the terrain file, the flexible customization of the scene terrain in the engine is realized, the technical problem that the terrain cannot be flexibly adjusted in the engine in the related technology is solved, and the production efficiency of the scene terrain is improved.

[0049] In this embodiment, a preset map editing component (such as Unity) or a mountain scatter tool can be used to build a basic terrain model, and the first terrain model and the second terrain model are created on the planar geometric body.

[0050] In an implementation manner of this embodiment, creating the first terrain model and the second terrain model on the planar geometric body includes: building a basic model set on the planar geometric body; grouping the basic model set into the first terrain model and the second terrain model; storing the first terrain model in a first tool node, and storing the second terrain model in a second tool node, where the first tool node is used to export the terrain model to be dug down, and the second tool node is used to export the terrain model to be raised.

[0051] In this embodiment, referring to the preset design drawing of the target scene terrain, a basic model set is built using an engine modeling tool. After modeling, all the models are divided into two groups. One group is used to raise the terrain, and the other group is used to lower the terrain. The two groups of models are stored in two nodes of the tool control panel (such as the hierarchical management panel) for later use. In one example, the first terrain model and the second terrain model are identified using a specific color or style. For example, the red model represents the terrain to be dug down, and the green model represents the terrain to be raised. The models to raise the terrain are stored under the Add node (the first tool node) of the engine modeling tool, and the models to lower the terrain (red) are stored under the Sub node (the second tool node). It also supports raising and lowering the terrain within the engine, easily creating landforms such as valleys, deep pits, rivers, and lakes. Among them, in the layout tab: SizeX sets the terrain size. Drag and drop into the Add node in the Add panel and into the Sub node in the Sub panel. In this way, the basic model is imported into the tool. After the settings are completed, without clicking any button, a sub-node is automatically generated for the terrain under the tool node.

[0052] Figure 3 It is a schematic diagram of generating the scene terrain in an embodiment of the present invention. First, a basic model set is built and grouped on a planar geometric body, and then the first terrain model is dug down and the second terrain model is raised.

[0053] In another embodiment of this embodiment, creating the first terrain model and the second terrain model on the planar geometric body includes: responding to the dragging instruction of the curve tool, drawing a curve on the planar geometric body to generate a terrain trend line, where the terrain trend line is used to indicate the scattering range of the terrain model to be generated; obtaining the scattering parameters of the terrain trend line, where the scattering parameters include at least one of the following: the ramp curve graph of the scattering range, the number of models, and the model scaling parameter; generating the first terrain model and the second terrain model on the planar geometric body using the scattering parameters.

[0054] In this embodiment, a custom mountain scatter tool is used. First, the curve tool of the model engine is used to drag and extend curves on the terrain, and then the number, position, and size of the mountain peaks are adjusted by adjusting the parameters on the tool panel, simplifying the production process of the first terrain model and the second terrain model. The implementation process of this embodiment can be integrated into a procedural mountain tool. The input sources of this procedural mountain tool include: a configuration table of the path string of the mountain peak model in the engine for reading mountain peak resources; the curves dragged out in the engine for generating the mountain range; and the parameter settings (parameter panel diagram) exposed on the tool panel, including the ramp curve graph of the scatter range, the number of mountain bodies, the minimum scale, the maximum scale, the uniform scale, and other parameters. The output is the mountains arranged on the map. By using the curve tool of this embodiment, the positions and sizes of a preset number of mountain peaks can be directly adjusted through the curves to form a mountain range.

[0055] Figure 4 It is a schematic diagram of creating the first terrain model and the second terrain model through the curve tool in an embodiment of the present invention.

[0056] In this embodiment, the first terrain model is dug down and the second terrain model is raised on the plane geometric body to generate a terrain file of the scene terrain, including: determining the lowest surface value of the first terrain model and determining the highest surface value of the second terrain model; reading the first initial terrain voxel set of the first terrain model and reading the second initial terrain voxel set of the second terrain model; merging each terrain voxel in the first initial terrain voxel set based on the maximum value of the longitudinal coordinate according to the lowest surface value to obtain a first intermediate terrain voxel set, and merging each terrain voxel in the first intermediate terrain voxel set based on the minimum value of the longitudinal coordinate to obtain the terrain height value of the first terrain model; merging each terrain voxel in the second initial terrain voxel set based on the maximum value of the longitudinal coordinate according to the highest surface value to obtain a second intermediate terrain voxel set, and merging each terrain voxel in the second intermediate terrain voxel set based on the minimum value of the longitudinal coordinate to obtain the terrain height value of the second terrain model; generating the terrain file of the scene terrain based on the terrain height value of the first terrain model and the terrain height value of the second terrain model.

[0057] Mapping the model into the terrain file of the map editing component. Mapping means that the height of the terrain is calculated for each terrain voxel according to the highest surface of the corresponding "raised" geometric body and the lowest surface of the corresponding "dug-down" geometric body. The calculation process of raising and digging down in the digital asset production software is shown in the following figure. First, each voxel is merged based on the maximum value in the Y direction, and then each voxel is merged based on the minimum value in the Y direction to generate the terrain file of the scene terrain.

[0058] In an implementation manner of this embodiment, based on the terrain file, baking terrain detail parameters of the scene terrain locally in the modeling engine, and generating terrain layer data of the scene terrain includes:

[0059] S11, generating basic terrain data of the scene terrain locally in the modeling engine using the terrain file;

[0060] S12, performing terrain distortion on the basic terrain locally in the modeling engine to generate a first detailed terrain;

[0061] In an example, performing terrain distortion on the basic terrain locally in the modeling engine includes: performing a blur process on the basic terrain locally in the modeling engine to obtain a first intermediate model; dividing the first intermediate model into a first geometric body and a second geometric body; sequentially performing a distortion process and a noise process on the first geometric body, and performing a custom modification on the second geometric body.

[0062] This embodiment uses the baking interface of the scene production engine to access a custom tool, adding detailed deformation to the basic terrain generated by modeling; and performing erosion on the terrain with detailed deformation.

[0063] The terrain distortion component of this embodiment includes nodes such as blur, distort, noise, and object_merge nodes. During the detailed deformation process, through the superposition of nodes such as blur, distort, and noise, preliminary results of removing sharp corners, distorting edges, and natural undulations of the plane are obtained respectively. Among them, the role of the object_merge node is to access the model passed in when modifying the terrain for the second time. Since the distort and noise nodes have a relatively random effect and may cause destructive deformation to key positions, when the user needs to precisely control certain areas (the second geometric body), the geometric body placed in the map editing component can be accessed through object_merge to modify the terrain change degree at the access position, achieving the purpose of flexibly and precisely controlling the detailed deformation.

[0064] The above example regarding terrain distortion includes two aspects. The first is to solve the problem of too hard edges of the geometric body by combining blur and multiple distort and noise calculations. The second is to support precise secondary modification of the second geometric body for the distortion result through object_merge to meet the design requirements.

[0065] S12, performing surface erosion on the first detailed terrain locally in the modeling engine to generate a second detailed terrain;

[0066] In one example, performing surface erosion on the first detailed terrain locally in the modeling engine includes: determining a first geometric body and a second geometric body in the first detailed terrain, where the second geometric body corresponds to a terrain area with custom modifications; generating an erosion protection mask on the second geometric body; obtaining preset erosion parameters, and performing erosion processing on the surface layer of the first detailed terrain using the erosion parameters.

[0067] This example uses preset erosion rules to perform surface erosion. This embodiment generates a mask for the geometric body (the second geometric body) used for secondary modification, and also retains the areas that need to be precisely controlled to avoid damage caused by global erosion; the embodiment also pre-configures preset erosion parameters and exposes the key parameters to the scene production engine.

[0068] S13. Locally allocate texture maps for the second detailed terrain in the modeling engine to generate terrain layer data of the scene terrain.

[0069] In one example, locally allocating texture maps for the second detailed terrain in the modeling engine includes: locally responding to an operation instruction of a curve tool in the modeling engine, and enclosing a number of target areas in the second detailed terrain, where each target area corresponds to a landform range of a landform type; for each target area, searching for a texture map that matches the landform type of the target area; baking the texture map in the target area.

[0070] This example uses preset surface mapping rules to allocate texture maps for the surface and outputs terrain layer data in a specified format common to digital asset production software, such as data in the.terrainlayer format commonly used by map editing components. When allocating texture maps for the terrain, the curve tool in the production engine is used to enclose areas during area division, so that lines are used instead of hand-drawn brushes to precisely outline the landform range. When modifying, there is no need to smear too much, and only the control points of the curve need to be dragged to adjust the landform range. At the same time, this embodiment completes the conversion of model - terrain - erosion through local baking within the engine, solving the problem of not being able to intuitively see the adjusted effect within the engine.

[0071] Figure 5 It is a schematic diagram of the terrain detail processing of the scene terrain in the embodiment of the present invention. First, the basic terrain is distorted, then surface erosion is performed, and finally texture mapping is carried out to integrate the snowfield and lawn areas with the original landform.

[0072] The solution of this embodiment is different from other large world generation tools and processes. When applied to game projects, it can be perfectly compatible with the official data format of map editing tools, reducing the learning costs of artists and level designers and enabling the stable and smooth production of resources. This embodiment expansively supports the need for artists and level designers to precisely modify the terrain by editing models during actual application. Level designers can use the tools of this solution to modify the terrain until they are satisfied, avoiding overly strong terrain programmability and randomness and weak controllability of designers, which may prevent it from being implemented in the final project.

[0073] In the engine, PDG (Procedural Dependency Graph, literally translated as procedural dependency graph) is used to bake terrain details, adding basic details - adding erosion - adding texture maps. The parameters of the walking iteration are baked locally according to the general parameters preset in digital asset production software, and it supports exposing the parameters for adjustment in the engine. From building the basic model to baking the surface texture map, all can be directly adjusted within the engine to produce assets. It uses the built-in functions of digital asset production software and presets a set of parameters with relatively ideal default effects according to the level design requirements, and packages them into the tools of the map editing component.

[0074] The beneficial effects of the present invention are as follows: It solves the defects of the existing technical solutions and retains the advantages of the existing production solutions, being compatible with the official data format of map editing components. At the same time, it has the following technical effects: It solves the problem of being unable to flexibly adjust the terrain within the engine. It solves the problem of being unable to intuitively view the effects after adjustment within the engine. This solution performs local baking within the engine to complete the conversion of model - terrain - erosion. It solves the problem of being unable to programmatically control the distribution of mountain peaks. It further solves the problem of the distribution of the basic model. For example, when a user uses multiple modeled mountain peaks to create a mountain range, they need to adjust the position and size of each mountain peak in sequence. The procedural mountain range tool can directly adjust the positions and sizes of dozens of mountain peaks through curves to form a mountain range.

[0075] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by means of software plus a necessary general hardware platform. Of course, it can also be implemented by hardware, but in many cases, the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the existing technology, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disc) and includes several instructions for causing a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in various embodiments of the present invention.
