Description

Technical Field

[0001] The present application relates to the field of image processing technology, and in particular to a rendering method, device, electronic device and readable storage medium. Background Art

[0002] As open world games become more and more popular, the terrain in the scene is getting larger and larger, and the memory and rendering overhead are also significantly increased. Especially for mobile games, the terrain in the scene is very large. Among them, the terrain effect at a long perspective is not obvious, but it still takes up a lot of performance overhead.

[0003] In the existing technology, UE4 engine is usually used for rendering of large scenes. The foreground terrain is Landscape (a rendering method in UE4, and there is no unified name in the industry), and the distant terrain can be implemented using LOD (Level of Details, a rendering method in UE4). It can be simply understood as baking a small piece of terrain into a simple static mesh and storing it in the level.

[0004] However, there are still many shortcomings in using the UE4 engine. For example, the default LOD of the terrain in the UE4 engine is to divide the terrain into many models, and then splice multiple models together. This method cannot achieve topological continuity, and the seams between plots can be seen. For example, the UE4 engine is not suitable for larger scenes of 4K and above. In larger scenes of 4K and above, although the LOD reduces the number of model faces, the large increase in plots will lead to extremely frequent input / output (IO), which increases IO consumption and takes up a lot of performance overhead. Summary of the invention

[0005] In view of the above situation, the embodiments of the present application propose a rendering method, device, electronic device and readable storage medium to overcome or partially overcome the defects of the prior art.

[0009] Generate a simple level model according to the real terrain corresponding to the near-view terrain;

[0010] The level model is merged with the terrain prosthesis to achieve rendering of the scene to be rendered.

While ensuring the overall effect, this application greatly reduces the memory demand and the frequency of IO input / output (Input / Output), achieving a balance between effect and performance overhead; for players, based on the different performance of their mobile devices, while ensuring a relatively ideal effect, it reduces memory and performance overhead as much as possible, greatly improving the gaming experience.

[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0026] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0027] In the prior art, the UE4 engine is usually used to render the scenes in the game. Since the LOD of the UE4 engine divides the terrain into many plots, each plot generates a new static mesh according to the parameters of the LOD, and multiple models are spliced ​​into the distant terrain, the continuity of the topological structure cannot be achieved. Players can see the gaps between models, and the gaming experience is poor. In the open world, the terrain must reach 4K (resolution, which means that the pixel value per row in the horizontal direction reaches or approaches 4096, without considering the aspect ratio) or even larger, so there will be many plot levels. When the player moves at high speed, loading and unloading will be triggered frequently, which will cause a lot of IO consumption, greatly occupy the device performance, and even cause freezes.

[0028] The idea of ​​this application is that, in view of the above situation, this application introduces a terrain prosthesis strategy. First, according to the real terrain submitted by the artist, a terrain prosthesis with lower precision is generated to replace the distant terrain. Then it is merged with the near terrain using the terrain simplified model rendering technology, thereby realizing the rendering of the entire scene. In this way, the display effect of the distant terrain can be guaranteed, and the LOD of the distant plots does not need to be loaded, thereby achieving the purpose of significantly reducing IO, which is especially suitable for large scenes of 4K and above.

[0029] Figure 1A schematic diagram of a rendering method according to an embodiment of the present application is shown. Figure 1 It can be seen that the present application at least includes steps S110 to S140:

[0030] Step S110: receiving a terrain prosthesis generated according to a real terrain, and generating a material and a texture of the terrain prosthesis, wherein the terrain prosthesis is a static mesh.

[0031] The real terrain of a scene in the game is usually carved by art professionals. The real terrain is the real visual experience that game developers want to provide to gamers. However, in reality, due to the large size of the scene and the increasing resolution requirements, if the entire large scene is rendered using a relatively high-precision method, the amount of calculation will be very large, and the hardware performance requirements will be very high, which is a loss-making method.

[0032] In the prior art, in order to avoid the above situation, the UE4 engine is used to render the scenes in the game, and the terrain is divided into many plots. A new static mesh is generated for each plot according to the LOD parameters. Multiple models are spliced ​​into the distant terrain, and the continuity of the topological structure cannot be achieved. Players can see the gaps between models, and the gaming experience is poor. It is not suitable for large scenes with high resolution.

[0033] This application provides a rendering method that can solve the above problems well. First, a terrain prosthesis generated according to the real terrain is received. The terrain prosthesis is a static mesh. The static mesh is used as the model of the distant terrain prosthesis. The static mesh is the basic unit for creating the level world scene geometry in the Unreal Engine, and its form is usually a "static mesh actor". The use of static meshes can achieve a relatively ideal effect, which can not only ensure the ideal visual effect, but also save the performance overhead of hardware.

[0034] The terrain prosthesis is generated for the entire scene to be rendered, and the terrain prosthesis can be stored in the scene to be rendered all the time, thereby avoiding the current situation of frequently triggering loading and unloading of land levels in the prior art and significantly reducing the IO frequency.

[0035] In the terrain prosthesis, a simple shape can be used to represent an "object", such as a cone to represent a mountain. Of course, since the terrain prosthesis is a static mesh, the material and texture of the terrain prosthesis need to be generated during the rendering process. That is, the surface of the cone needs to be covered with grass, trees, mountains, rocks, etc., and the grass, trees, mountains, rocks, etc. can be expressed with materials and textures.

[0036] For the generation of materials and textures, reference may be made to any of the existing technologies, such as the method for generating materials and textures in the UE4 engine.

[0037] It should be noted that the terrain prosthesis is a whole static mesh generated for the entire scene, so it will not make players see the gaps between models as in the prior art using UE4's LOD.

[0038] Step S120: dividing the scene to be rendered into near-view terrain and far-view terrain according to the position information of the virtual character in the scene to be rendered.

[0039] The scene to be rendered is divided into near-view terrain and far-view terrain. For the segmentation process, the distance between the virtual character and the scene to be rendered should be taken into consideration. For example, a distance threshold can be preset based on the distance, and the terrain whose distance to the target virtual character is less than or equal to the distance threshold is defined as near-view terrain, and the terrain whose distance to the target virtual character is greater than the distance threshold is defined as far-view terrain. This segmentation method is only an exemplary description, and other segmentation methods can also be adopted, which can be determined according to the rendering effect to be achieved.

[0040] Step S130: Generate a simple level model according to the real terrain corresponding to the near-field terrain.

[0041] For the near-view terrain and the distant terrain, this application adopts two different processing methods. For the near-view terrain part, a method that can achieve higher precision and more ideal effect is required, which can be selected as needed. For example, the multi-level of detail (LOD) method in the prior art can be used. Since the precision requirement for the near-view terrain is relatively high, the LOD level can be set relatively high to meet the expected precision requirements. In LOD, in the near-view terrain, there are usually multiple models, and LOD usually renders each model separately. The use of the LOD method can obtain a more ideal rendering effect, but it consumes a lot of hardware performance.

[0042] To this end, a level model can be used to integrate multiple models into one model instead of the above method, such as using a layered level of detail (HLOD) method to first establish a model community and then generate a level model.

[0043] The process of establishing a model community determines how to group multiple models in the scene, the number of groups, whether to generate materials, etc. By fully considering the space, observation frequency, and the creator's self-defined strategy, the reasonable grouping of models is achieved, thus obtaining a cluster composed of models in different groups.

[0044] After obtaining a satisfactory model cluster, you can generate a level model. The level model generates a new mesh for the obtained model cluster. In this process, the materials will be combined and a new light map will be generated (if necessary). Although the level model uses a simple model to replace a bunch of models, the existence of the level model greatly reduces the complexity of the scene model, and can also reduce the Draw Call through certain settings. It is an effective means to balance the effect and consumption.

[0045] Step S140: Fusing the rendered near-view terrain with the terrain prosthesis to achieve rendering of the scene to be rendered.

[0046] Finally, the generated level model is combined with the terrain prosthesis to complete the rendering of the scene to be rendered.

[0047] This application does not limit the fusion method. For example, the corresponding position of the terrain prosthesis can be replaced with the generated level model in the same position, thereby completing the rendering work of the entire scene to be rendered.

[0048] Due to the existence of the terrain prosthesis, a high-precision rendering method was used for the near-field terrain at this time; while for the distant terrain, no processing was done, and the terrain prosthesis after generating materials and mapping was still retained, thus achieving the goal of both ensuring visual effects and reducing performance consumption.

[0049] Depend on Figure 1 It can be seen from the method shown that the present application divides the game scene into near-view terrain and far-view terrain according to the position of the target virtual character in the game scene, replaces the far-view terrain with a terrain prosthesis, and uses a terrain model based on the real terrain for the near-view terrain, thereby achieving the rendering of the entire game scene. While ensuring the overall effect, the present application greatly reduces the memory demand and IO frequency, achieving a balance between effect and performance overhead; for players, based on the different performance of players' mobile devices, while ensuring a relatively ideal effect, the memory and performance overhead are reduced as much as possible, greatly improving the gaming experience.

[0050] In some embodiments of the present application, receiving a terrain prosthesis generated based on real terrain includes: receiving the terrain prosthesis, wherein the terrain prosthesis is generated based on the real terrain based on Houdini software, and the height of each vertex of the terrain prosthesis is lower than the real terrain.

[0051] The terrain prosthesis can be understood as a large model prosthesis for the entire scene. The model prosthesis is a proxy mesh. The terrain prosthesis is usually generated by third-party software. The generation process of the terrain prosthesis can be generated by third-party software in the prior art. The idea is to simplify the real terrain. As mentioned above, a mountain is simplified into a cone, etc. The accuracy of the generated terrain prosthesis is lower than that of the real terrain, so as to reduce the amount of calculation. Since the distant terrain is far away, although the accuracy is reduced, its visual effect will not change significantly.

[0052] In some embodiments of the present application, the third-party software is Houdini (a three-dimensional computer graphics software, there is no unified Chinese name in the industry). Since Houdini is a product designed entirely based on the node model, Houdini has an interface for a third-party renderer, and can export scenes to other rendering engines for rendering. The reason why the present application recommends the use of Houdini software is that the programmatic node programming restrictions of Houdini software can be used to ensure that the height of each vertex of the terrain prosthesis is lower than the real terrain, so that "piercing the model" will not be caused, avoiding the bad gaming experience for game players due to piercing the model.

[0053] In some embodiments of the present application, the generation of materials and textures may refer to the following method: for materials, a first generation parameter of the material is received, and based on the first generation parameter, the material of the terrain prosthesis is generated, and the first generation parameter includes: material type, material color, material texture, etc.; for textures, a second generation parameter of the texture is received, and based on the second generation parameter, the texture of the terrain prosthesis is generated, and the second generation parameter includes: texture source, texture size, texture posture, etc.

[0054] For example, the generation of textures and materials can be based on the generation parameters of textures and materials, which can be set manually. For example, for the trunk of a tree model, when selecting the material, you can select the material raw material and the material texture. For example, if the material is originally wood and the material texture is pine, the model of the tree will show the appearance of a pine tree. Of course, for the mountains in the distance, there is no need to generate textures and materials for each tree. You only need to select the material of the mountain as a tree or a specific type of tree. If there are other objects on the mountain, such as a flying eagle, the eagle cannot be expressed by material. Here you can specify the texture source, texture size, texture posture and other parameters, and use the texture to display. It should be noted that there is a powerful database storage for textures and materials. When using them, you can directly call them by selection. If they are not in the database, you can also create them yourself and store them in the database for later use.

[0055] In other embodiments of the present application, for the generation of materials and textures, the following method can be referred to: receiving generation parameters of materials and textures, and generating material instances corresponding to the terrain prosthesis according to the generation parameters, and generating materials and textures of the terrain prosthesis according to the material instances.

[0056] Take materials as an example. When generating materials, hundreds of materials may be needed, which will affect the size of the package. In this regard, in some embodiments of the present application, materials may not be used directly, but material instances may be used. Material instances are instances of materials. Material instances inherit from materials and have the shader logic of materials, but only expose adjustable parameters (i.e., Params) and block the ability to edit shaders. The purpose is that when a certain model (or models) needs to modify parameters, it will not affect other models that use the material. And when the logic of the material is updated, all material instances will also be updated accordingly.

[0057] A material instance can integrate multiple materials together to form a material instance. In this application, since the terrain prosthesis is a permanent scene, the material instance can be a static material instance. By dragging the generated static material instance onto the terrain prosthesis, the generation of materials and textures can be achieved.

[0058] In some embodiments of the present application, in the above method, the merging of the level model with the terrain prosthesis includes: placing the terrain prosthesis at a corresponding position of the scene to be rendered; and in response to a scene loading instruction, executing the step of generating a level model based on the real terrain corresponding to the foreground terrain.

[0059] As for the terrain prosthesis, it can be understood as a permanent level of the scene. To keep it in the scene forever, you only need to place it at the corresponding position in the scene. It should be noted that this is the terrain prosthesis after the material and texture are generated.

[0060] When the game is running, when the virtual character in the game reaches a certain position, a scene loading instruction will be generated. At this time, the foreground terrain can be rendered in response to the scene loading instruction. Specifically, the step of generating a level model according to the real terrain corresponding to the foreground terrain is executed. It should be noted that the foreground terrain and the terrain prosthesis may have an overlapping part. For this part, the level model of the foreground terrain can be used to directly replace this part of the terrain prosthesis.

[0061] In some embodiments of the present application, the merging of the level model with the terrain prosthesis further includes: adjusting the highlight and roughness of the material and texture of the terrain prosthesis to make the terrain prosthesis close to the real terrain.

[0062] Since the foreground terrain is rendered based on the real terrain, the influence of light and shadow has been taken into account during the rendering. In the process of fusion with the terrain prosthesis, it is best to adjust the highlight position, roughness and other effects of the material and texture on the surface of the terrain prosthesis to pursue a rendering effect that is closer to the real terrain.

[0063] In some embodiments of the present application, in the above method, the highlight and roughness of the material and texture of the terrain prosthesis are adjusted, including: receiving effect parameters of the material and texture, and adjusting the display effect of the generated texture and material according to the effect parameters, wherein the effect parameters include highlight position and roughness.

[0064] Parameters such as light source position and roughness also have a great impact on the visual effects displayed by the model. After generating textures and materials, the display effects of the generated textures and materials can be adjusted according to the obtained effect parameters to improve the realism of the distant terrain prosthesis.

[0065] Taking the position of the light source as an example, the position of the sun at 8:00 am and 12:00 noon is different, and the shadows and grayscale formed are also different. Therefore, it is best to set these effect parameters and adjust the display effects of the textures and materials according to these effect parameters to achieve an effect that is very close to the real terrain.

[0066] These effect parameters can be set or adjusted manually. The staff can adjust these effect parameters according to the position of the light source in the foreground terrain and the roughness of the material, so that the display effect of the foreground terrain is more coordinated with the display effect of the distant terrain and more in line with the real terrain.

[0067] In some embodiments of the present application, the method further includes: integrating any of the above methods into an interface-callable script, so that the UE4 engine can call the script through the interface.

[0068] UE4 engine is the most common rendering engine at present. In this application, there are also many places where existing technologies are needed. For the convenience of use, the code that implements any method of this application can be synthesized into a script that can be called through an interface to facilitate the reference of the UE4 engine. That is, when rendering, the UE4 engine can still be used as a rendering engine, and by calling the script, the scene can be rendered using the method of this application.

[0069] Figure 2 A schematic diagram of a rendering method according to another embodiment of the present application is shown. Figure 2 It can be seen that this embodiment includes:

[0070] A terrain prosthesis generated by Houdini software according to the real terrain is received, and materials and textures of the terrain prosthesis are generated, wherein each vertex of the terrain prosthesis is lower than the real terrain.

[0071] A distance threshold is set to determine whether the distance between a model and the target virtual character is greater than the distance threshold. If so, the model is classified as distant terrain; if not, the model is classified as near terrain.

[0072] In response to the scene loading instruction, the terrain prosthesis is placed at the corresponding position of the scene to be rendered, and the existing method in UE4 is used to render the near-field terrain with high precision according to the corresponding real terrain to complete the rendering of the scene to be rendered.
