Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In the prior art, a UE4 engine is usually adopted to render a scene in a game, because the LOD of the UE4 engine divides a terrain into a plurality of plots, each plot generates a new static grid according to the parameters of the LOD, the plurality of models are spliced into a remote terrain, continuity of a topological structure cannot be achieved, a player can see gaps between the models, and the game experience is poor; in the open world, the terrain is required to reach 4K (the resolution ratio means that the pixel value of each row in the horizontal direction reaches or approaches 4096, and the picture-to-width ratio is not considered) or even larger, so that a plurality of plot gates exist, when a player moves at a high speed, loading and unloading are frequently triggered, large IO consumption is generated, the performance of equipment is greatly occupied, and even the situation of blocking is caused.
The utility model provides a design lies in, to above-mentioned circumstances, this application has introduced the tactics of topography false body, at first according to the true topography that fine arts submitted, generate a lower topography false body of precision for replace distant view topography, then fuse together its and the close-range topography that adopts the topography simplified die rendering technique, thereby realized the rendering of whole scene, can guarantee the display effect of distant topography like this, also can not need the LOD of loading distant place landmass, thereby reach and show the purpose that reduces IO, be particularly useful for 4K and above big scene.
Fig. 1 shows a schematic flowchart of a rendering method according to an embodiment of the present application, and as can be seen from fig. 1, the present application at least includes steps S110 to S140:
step S110: receiving a terrain prosthesis generated according to real terrain, and generating the material and the map of the terrain prosthesis, wherein the terrain prosthesis is a static grid.
The real terrain of a scene in a game, which is the real visual experience that game developers want to provide to game players, is typically carved by artistic personnel. However, in practice, because the scene is very large and the resolution requirement is higher and higher, if the whole large scene is rendered by a method with relatively high precision, the calculation amount is very large, the requirement on the hardware performance is very high, and the method is an irrevocable way.
In the prior art, in order to avoid the situation, a UE4 engine is used to render a scene in a game, a terrain is divided into a plurality of plots, each plot generates a new static grid according to the parameters of the LOD, a plurality of models are spliced into a remote terrain, continuity of a topological structure cannot be achieved, a player can see gaps between the models, and the game experience is poor; and are not suitable for large scenes with high resolution.
The rendering method can well solve the problems, firstly, a terrain prosthesis generated according to real terrain is received, the terrain prosthesis is a static grid, a static grid body is used as a model of a distant view terrain prosthesis, the static grid body is a basic unit used for creating a checkpoint world scene geometry body in an illusion engine, and the form of the static grid body is usually 'static grid body Actor'. The static grid body can achieve a relatively ideal effect, so that an ideal visual effect can be guaranteed, and the performance overhead of hardware can be saved.
The terrain prosthesis is generated aiming at the whole scene to be rendered, and the terrain prosthesis can be stored in the scene to be rendered all the time, so that the current situation that the block checkpoint is frequently triggered to be loaded and unloaded in the prior art is avoided, and the IO frequency is obviously reduced.
In a topographical prosthesis, a simple shape may be used to represent an "object", such as a hill, for example, as opposed to a vertebral body. Of course, because the terrain prosthesis is a static grid, in the process of rendering, the material and the map of the terrain prosthesis need to be generated, that is, the surface of the vertebral body needs to be covered with the vegetation mountain stones and other objects, and the vegetation mountain stones and other objects can be expressed by the material and the map.
For the generation of the texture and the map, any one of the prior arts may be referred to, such as the generation method of the texture and the map in the UE4 engine.
The terrain prosthesis is an integral static mesh body generated for the entire scene, and therefore, unlike the prior art, which uses the LOD of UE4, the player does not see the gap between the models.
Step S120: and according to the position information of the virtual character in the scene to be rendered, dividing the scene to be rendered into a near view terrain and a far view terrain.
The method includes dividing a scene to be rendered into a near view terrain and a far view terrain, considering a distance between a virtual character and the scene to be rendered, for example, a distance may be used as a basis, a distance threshold is preset, a terrain having a distance with a target virtual character less than or equal to the distance threshold is defined as the near view terrain, a terrain having a distance with the target virtual character greater than the distance threshold is defined as the far view terrain, and the dividing manner is only an exemplary description, and other dividing manners may be adopted, which may be determined according to a rendering effect to be achieved.
Step S130: and generating a checkpoint simplified model according to the real terrain corresponding to the close-range terrain.
For the short-range terrain and the long-range terrain, two different processing modes are adopted, for the short-range terrain part, a method with higher precision and more ideal effect can be required, and the method can be selected according to the requirement. Such as may be done using a prior art multiple level of detail (LOD) approach. Since the accuracy requirement for the close-range terrain is relatively high, the LOD level can be set relatively high to meet the expected accuracy requirement. In the LOD, in the near-field terrain, a plurality of models are usually included, and the LOD usually renders each model separately, and a relatively ideal rendering effect can be obtained by using the LOD method, but a large amount of hardware performance is consumed.
For this, the above-mentioned manner may be replaced by a manner of integrating a plurality of models into one simple model by using a checkpoint simple model, for example, by using a hierarchical level of detail (HLOD) method, a model community is first established, and then a checkpoint simple model is generated.
The process of establishing the model community determines how to group a plurality of models in a scene, the number of the groups, whether to generate materials and the like. The reasonable grouping of the models is realized by fully considering the space, the observation frequency, the self-positioning strategy of a maker and the like, so that a cluster consisting of different grouped intra-group models is obtained.
After a satisfactory model cluster is obtained, a checkpoint simplified model can be generated, namely, a new grid body is generated for the obtained model cluster, in the process, materials are combined, and a new illumination map is generated (if needed).
Step S140: and fusing the rendered close-range terrain with the terrain prosthesis to realize the rendering of the scene to be rendered.
And finally, fusing the generated checkpoint simple model with the terrain prosthesis to finish rendering the scene to be rendered.
The fusion mode is not limited in the application, and the generated checkpoint short-form co-location is adopted to replace the corresponding position of the terrain prosthesis, so that the rendering work of the whole scene to be rendered is completed.
Due to the existence of the terrain prosthesis, a high-precision rendering method is adopted for rendering the close-range terrain at this time; and for distant terrain, the terrain prosthesis with generated materials and pictures is still reserved without processing, so that the aims of ensuring the visual effect and reducing the consumption of performance are fulfilled.
As can be seen from the method shown in fig. 1, according to the position of the target virtual character in the game scene, the game scene is divided into the near-view terrain and the far-view terrain, the far-view terrain is replaced by the terrain prosthesis, and the near-view terrain is replaced by the terrain simplified model according to the real terrain, so that the rendering of the whole game scene is realized. On the premise of ensuring the overall effect, the memory demand and IO frequency are greatly reduced, and the balance between the effect and the performance overhead is achieved; for the player, aiming at different mobile device performances of the player, under the condition of ensuring a relatively ideal effect, the memory and performance overhead is reduced as much as possible, and the game experience is greatly improved.
In some embodiments of the application, the receiving a terrain prosthesis generated from real terrain comprises: receiving the terrain prosthesis, wherein the terrain prosthesis is generated according to real terrain based on Houdini software, and the height of each vertex of the terrain prosthesis is lower than the real terrain.
The terrain prosthesis can be understood as a large model prosthesis for the whole scene, the model prosthesis is a proxy grid, the terrain prosthesis is usually generated by third-party software, and for the generation process of the terrain prosthesis, the third-party software in the prior art can be used for generating the terrain prosthesis, and the idea is to simplify the real terrain, as mentioned above, a mountain is simplified into a vertebral body and the like. The accuracy of the generated terrain prosthesis is lower than that of the real terrain, so that the calculation amount can be reduced, and the visual effect of the terrain prosthesis cannot be obviously changed although the accuracy is reduced because the distance of the distant terrain is relatively far.
In some embodiments of the present application, the third-party software is Houdini (a three-dimensional computer graphics software, which has no unified chinese name in the industry for a moment), and since Houdini is a product designed based on a node mode, Houdini has an interface of a third-party renderer, and can export a scene to other rendering engines for rendering. The reason why the Houdini software is recommended to be used is that the height of each vertex of the terrain prosthesis is lower than that of the real terrain through the programming node programming limitation of the Houdini software, so that 'die-cutting' is avoided, and bad game experience brought to game players by die-cutting is avoided.
In some embodiments of the present application, for the generation of the material and the map, reference may be made to the following methods: for a material, receiving a first generation parameter of the material, and generating the material of the terrain prosthesis according to the first generation parameter, wherein the first generation parameter comprises: material type, material color, material texture, etc.; for a map, receiving a second generation parameter of the map, and generating the map of the terrain prosthesis according to the second generation parameter, wherein the second generation parameter comprises: source of the map, size of the map, pose of the map, etc.
For example, for the generation of the map and the material, the generation parameters of the map and the material may be generated, and the generation parameters may be set manually, for example, for the trunk portion of a tree model, when the material is selected, the material raw material and the material texture may be selected, and if the material is selected to be wood originally, and the material texture is pine texture, the tree model may show a pine appearance. Certainly, for a mountain in a long-distance view, generation of a map and a material of one tree is not needed, the material of the mountain is only selected to be the tree or a specific tree, if other objects exist on the mountain, if flying hawks exist, the hawks cannot adopt material representation, and parameters such as a map source, a map size, a map posture and the like can be designated and displayed by the map. It should be noted that, there is a very strong database storage for the map and the material, and when in use, the database can be directly called by selection, or if the database does not exist, the database can be built by itself and stored in the database to be called.
In other embodiments of the present application, for the generation of the texture and the map, reference may be made to the following methods: and receiving generation parameters of the material and the map, generating a material example corresponding to the terrain prosthesis according to the generation parameters, and generating the material and the map of the terrain prosthesis according to the material example.
Taking the material as an example, when generating the material, hundreds of materials may be needed, thereby affecting the size of the bag body, for this reason, in some embodiments of the present application, the material may not be directly used, but a material instance is adopted, which is an instance of the material, the material instance inherits the material, possesses shader logic of the material, but exposes adjustable parameters (i.e., Params) only, and shields the capability of editing the shader, so that when some model(s) need to modify the parameters, other models using the material may not be affected. And when the logic of the material is updated, all the material examples are updated accordingly.
The material example can be in the same place a plurality of materials integration, forms a material example, and in this application, because the topography prosthesis is the scene forever, so the material example can be static material example, drags the static material example that generates to the topography prosthesis on, can realize the generation of material and picture.
In some embodiments of the present application, in the above method, the fusing the checkpoint profile with the topographic prosthesis comprises: placing the terrain prosthesis at a corresponding position of the scene to be rendered; and responding to the scene loading instruction, executing the step of generating the checkpoint simplified model according to the real terrain corresponding to the close-range terrain.
For the terrain prosthesis, it can be understood as a permanent checkpoint of a scene, and in a permanent scene, it is only required to place the terrain prosthesis at a corresponding position in the scene, and it should be noted that the terrain prosthesis after generating a material and a map is used here.
When a game is operated, when a virtual character in the game reaches a certain position, a scene loading instruction is generated, a near-view terrain can be rendered in response to the scene loading instruction, specifically, a step of generating a checkpoint short mould according to a real terrain corresponding to the near-view terrain is executed, it needs to be noted that a part of the near-view terrain and a terrain prosthesis may overlap, and for the part, the checkpoint short mould of the near-view terrain is adopted to directly replace the terrain prosthesis.
In some embodiments of the present application, the fusing the checkpoint profile with the topographic prosthesis further comprises: and adjusting the material of the terrain prosthesis and the highlight and roughness of the map so as to enable the terrain prosthesis to be close to the real terrain.
Because the close-range terrain is rendered according to the real terrain, the influence of light and shadow is considered in the rendering, and in the fusion process with the terrain prosthesis, the effects of the material of the surface of the terrain prosthesis, the highlight position, the roughness and the like of the map are preferably adjusted to pursue the rendering effect which is closer to the real terrain.
In some embodiments of the present application, in the above method, the adjusting the highlight and the roughness of the material and the map of the terrain prosthesis comprises: receiving the effect parameters of the material and the map, and adjusting the display effect of the generated map and the material according to the effect parameters, wherein the effect parameters comprise highlight position and roughness.
The parameters such as the position of the light source, the roughness and the like also have great influence on the visual effect displayed by the model, and after the chartlet and the material are generated, the display effect of the generated chartlet and the material can be adjusted according to the obtained effect parameters so as to improve the reality degree of the distant-view terrain prosthesis.
Taking the light source position as an example, 8 am: 00, and 12 noon: 00, the position of the sun is different, and the formed shadow, gray scale and the like are also different, so that the effect parameters are preferably set, and the display effect of the chartlet and the material is adjusted according to the effect parameters so as to achieve the effect very close to the real terrain.
The effect parameters can be manually set or adjusted, and workers can adjust the effect parameters according to the light source position in the close-range terrain, the roughness of the material and the like, so that the display effect of the close-range terrain and the display effect of the far-range terrain are more coordinated and are also more connected with the real terrain.
In some embodiments of the present application, the method further comprises: any of the above methods are integrated into an interface-callable script so that the UE4 engine can call the script through the interface.
The UE4 engine is the most common rendering engine at present, and there are many places in the application that need to be assisted by the prior art, and for convenience of use, the code for implementing any method of the application can be combined into a script that can be called through an interface for the convenience of reference of the UE4 engine. Namely, during rendering, the UE4 engine can still be used as a rendering engine, and the method of the present application can be used to render a scene by calling a script.
