Detailed Description
In order to make the technical solutions of the present invention better understood, 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 a part of the embodiments of the present invention, 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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for rendering a virtual model, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system, such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
In addition, it should be noted that a terminal device (e.g., a mobile phone, a tablet, etc.) allowing a game may be an execution subject of the rendering method of the virtual model provided in the present embodiment.
Optionally, fig. 1 is a flowchart of a rendering method of a virtual model according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S102, at least one virtual model participating in mirror reflection and a plurality of maps corresponding to the virtual model are obtained.
In step S102, the virtual model is a model participating in mirror reflection in the game, such as a table, a chair on a smooth ground, a virtual character opposite to a mirror, trees and buildings beside a lake, and the like. In addition, each virtual model corresponds to multiple tiles, where each face of the virtual model corresponds to one tile, and typically, a virtual model has multiple faces.
In an alternative embodiment, the terminal device first determines a predetermined virtual object, such as a mirror, a smooth floor, a glass, a water surface, etc., that produces a mirror image effect from the game scene. Then, determining a virtual model which can be reflected by a preset virtual object in a game scene to obtain at least one virtual model participating in mirror reflection, and simultaneously, acquiring a plurality of maps corresponding to the virtual model by the terminal equipment.
It should be noted that, the scheme provided by this embodiment may obtain the virtual model and the multiple maps corresponding to the virtual model in the game scene during the game operation, and may also obtain the virtual model and the multiple maps corresponding to the virtual model in the process of creating the game in the early stage.
And step S104, carrying out surface to be rendered screening processing on at least one virtual model to obtain a target virtual model.
It should be noted that, during the process of rendering the virtual model, there may be surfaces that do not need to be rendered, for example, one surface of the virtual model a is attached to one surface of the virtual model B, and at this time, the surfaces attached to each other between the virtual models a and B do not need to be rendered.
In step S104, the to-be-rendered surface processing is performed on the virtual model, a surface that does not need to be rendered (for example, the above attaching surface) is removed from the plurality of surfaces of the virtual model, the to-be-rendered surface that needs to be rendered is selected, and only the to-be-rendered surface that needs to be rendered is rendered, thereby reducing rendering consumption.
And step S106, carrying out size optimization processing on the multiple maps to obtain the target map.
In step S106, the size optimization process may be performed on the plurality of maps, and the sizes of the plurality of maps may be reduced.
It should be noted that, the larger the size of the map is, the more system resources are consumed when rendering the virtual model, and under the condition that the display effect is not affected, the size of the map is appropriately reduced, so that the rendering consumption can be effectively reduced, and the rendering efficiency is improved.
And step S108, rendering the target virtual model in the reflective camera according to the target map.
In step S108, the reflection camera is a virtual camera automatically generated by the game program, and captures an inverted image of the virtual model based on the reflection plane opposite to the shooting direction of the game host camera, so as to achieve the effect of simulating mirror reflection. The reflection camera can change in real time along with the position change of the game main camera, and the game main camera is a main visual angle camera used for rendering all image information in a game scene during game running.
It should be noted that the terminal device may only enable the reflection camera to render the target virtual model, and the game host camera does not render the target virtual model any more, so that the rendering times of the target virtual model are reduced, and the rendering consumption is reduced. Moreover, the target virtual model rendered by the reflex camera is the virtual model with the reduced number of maps and the reduced size of the maps, so that compared with the existing method for directly rendering the virtual model, the method provided by the embodiment can effectively reduce rendering consumption.
Based on the solutions defined in steps S102 to S108, it can be known that, in the embodiment of the present invention, after at least one virtual model participating in mirror reflection and multiple maps corresponding to the virtual model are obtained by reducing the number of maps of the virtual model and reducing the size of the maps, a target virtual model is obtained by performing to-be-rendered surface screening processing on the at least one virtual model, then size optimization processing is performed on the multiple maps to obtain a target map, and finally, the target virtual model is rendered in the reflex camera according to the target map.
It is easy to note that, in the above process, by performing to-be-rendered surface screening processing on the virtual model, a target rendering surface to be rendered can be selected from a plurality of to-be-rendered surfaces of the virtual model, so that the number of surfaces rendered by the virtual model is reduced, and rendering consumption of specular reflection is reduced. In addition, in the application, size optimization processing is further performed on multiple maps of the virtual model, so that the size of the maps is reduced, and rendering consumption of specular reflection is further reduced.
Therefore, the scheme provided by the application achieves the aim of performing mirror reflection rendering on a plurality of virtual models, so that the technical effect of reducing rendering consumption in the mirror reflection rendering process is achieved, and the technical problem that rendering consumption is large in the mirror reflection rendering process in the prior art is solved.
In an optional embodiment, after obtaining at least one virtual model participating in mirror reflection and multiple maps corresponding to the virtual model, the terminal device performs to-be-rendered surface screening processing on the at least one virtual model to obtain a target virtual model. Specifically, the terminal device determines a model to be rendered, of which the model distance meets a preset condition, from at least one virtual model, then screens out a target rendering surface from the surfaces to be rendered of the model to be rendered according to a preset rule, and generates a target virtual model according to the target rendering surface. Wherein, the model distance is the distance between at least one virtual model and the game main camera.
Optionally, the terminal device obtains a distance (i.e., a model distance) between at least one virtual model participating in the mirror reflection and the game host camera, compares the model distances corresponding to each virtual model, and determines a preset number of virtual models closest to each other as the models to be rendered. Then, the terminal device screens out a target rendering surface from a plurality of to-be-rendered surfaces of the to-be-rendered model. The terminal equipment can screen the target rendering surface according to whether the sight direction and the illumination direction corresponding to the main game camera on the surface to be rendered of the virtual model are the same. For example, the terminal device obtains a sight vector corresponding to a sight direction corresponding to a game master camera on a surface to be rendered of the virtual model and an illumination vector corresponding to an illumination direction, and calculates a dot product result of the sight vector and the illumination vector, if the dot product result is greater than 0, the sight direction corresponding to a main camera on the surface to be rendered of the virtual model is represented to be the same as the illumination direction, and at the moment, the terminal device marks the surface to be rendered as a target rendering surface; if the dot product result is not greater than 0, it indicates that the sight line direction is not the same as the illumination direction, and at this time, the terminal device does not mark the to-be-rendered logo, that is, the to-be-rendered logo is not the target rendering face.
In an optional embodiment, after the target virtual model is obtained, the terminal device further performs size optimization on the multiple maps to obtain the target map. Specifically, the terminal device obtains the original sizes of the multiple maps, and adjusts the original sizes of the multiple maps to preset sizes to obtain the target map, wherein the preset sizes are smaller than the original sizes. For example, the terminal device adjusts a plurality of tiles having a pixel size of 1024 × 1024 to a tile having a pixel size of 320 × 320.
It should be noted that the preset size may be set by a game developer, or the size of the map may be adjusted according to a preset proportion, where the preset proportion may be determined according to image information of the map and/or actual requirements, for example, in actual applications, if the map needs to be displayed in high definition, a preset proportion with a smaller value may be set; for another example, the definition of the map is relatively high, but in practical application, a preset ratio with a relatively large value is set without displaying the map in a high definition.
In an optional embodiment, before performing size optimization processing on the multiple maps to obtain the target map, the terminal device may further remove preset attribute map channels corresponding to the multiple maps; and/or removing the preset material variants corresponding to the multiple maps.
It should be noted that, in the game, the terminal device may render the virtual model using the physical material of PBR (physical-Based Rendering), but the calculation is relatively complex, and the pixel precision of the used map is typically 128 pixels/meter. However, in most cases, the reflection image does not require too much fine detail, so in the present application, the purpose of reducing the rendering consumption of the target virtual model can be achieved by simplifying the complexity of the material. For example, removing the attribute mapping channel that expresses texture (i.e., pre-setting the attribute mapping channel), reducing texture variations, using the simplest color mapping, and reducing mapping accuracy, e.g., compressing mapping accuracy to 32 pixels/m or less.
The rendering consumption can be further reduced on the basis of the existing scheme by any one of the three modes.
In an optional embodiment, after the original sizes of the multiple maps are adjusted to the preset size, the terminal device further acquires the map information included in the multiple maps, and combines the multiple maps after the size adjustment based on the map information to obtain the target map.
It should be noted that a set of maps includes a basic color map, a metallization map, a roughness map, a normal map, and the like. These maps work together in the same material, affecting different attributes to achieve different material effects. Wherein, a set of maps comprises one or more maps, depending on the technology used.
Alternatively, a simple scenario is taken as an example for explanation, for example, in the game scenario shown in fig. 2, the big cube is composed of 8 independent small cubes, and each small cube has an independent material, where a dotted line portion in fig. 2 represents a mirror image of the big cube through a mirror surface, a value of Batches corresponding to fig. 2 is 24, a value of TRIS corresponding to 19.4k, and a value of SetPass calls corresponding to 24. After the specular reflection is turned off, for example, in the game scene with the specular reflection turned off shown in fig. 3, the number of faces to be rendered is reduced by 9600 faces, the value of Batches is 12, the value corresponding to TRIS is 9.8k, the value corresponding to SetPass calls is 12, and the values corresponding to Batches and SetPass calls are both reduced, where the reduced parts are the number of faces, the number of individuals, and the number of materials of eight small cubes.
Further, based on the scenes shown in fig. 2 and 3, the multiple maps corresponding to the minicubes in fig. 2 and 3 are merged. Alternatively, the three-dimensional production software such as MAX may be used to produce, and finally obtain a map with 12 triangular surfaces, for example, a map corresponding to a cube in a white frame in the schematic diagram of the production target model shown in fig. 4.
It should be noted that, in the baking software MAX, by re-expanding the target virtual model, information of multiple maps corresponding to the target virtual model is collected into one map, and the map is the target map corresponding to the target virtual model.
Through the process, the whole model with lower surface number can be obtained, and the maps of the target virtual model are combined into one set, so that a set of optimized low-model maps can be obtained.
In an alternative embodiment, the terminal device further obtains an original position of the at least one virtual model and sets the target virtual model at the original position before rendering the target virtual model in the reflex camera according to the target map.
Optionally, the optimized target map is imported into a game engine, and the target virtual model is placed at a position overlapping with the virtual model in the original scene. For example, in the interface of the rendering virtual model shown in fig. 5, the macrocube (i.e., the target virtual model) after the face to be rendered is subjected to the filtering process is placed at the position of the macrocube before the face to be rendered is subjected to the filtering process.
In an alternative embodiment, after obtaining the target map, the terminal device further sets the target virtual model in the reflective layer. For example, in fig. 5, the large cube (i.e., the target virtual model) after the surface to be rendered is filtered is individually layered and disposed in the Reflection layer (i.e., the Reflection layer).
Optionally, the terminal device sets a reflective layer in the reflective camera, renders the target virtual model according to the target map, removes the reflective layer from the game master camera, and renders at least one virtual model. For example, in the setting interface of the game master camera shown in fig. 6, the game master camera culling layer is set; in the setting interface of the reflective camera shown in fig. 7, the specular reflection script is set to render only the reflection layer.
In another alternative embodiment, the reflective layer is removed from the game master camera and at least one virtual model is rendered, i.e. the game master camera only renders the virtual model in the non-reflective layer.
In the above, the specular reflection script is a reflection script added to the plane in the game engine to realize a real-time specular reflection effect. The specular reflection script may set parameters such as the degree of blurring of the reflection, the hierarchical culling of the content of the reflection, etc. Rendering culling means that the game master camera culls the images acquired by the game master camera through a layer (e.g., a Reflection layer), and if the layer in which the virtual model is set to be culled by the camera, the camera does not render the virtual model any more.
It should be noted that, in the game engine, each virtual model may perform layer setting, where the type of the layer may be defined according to actual needs. Setting up different layers can realize performing different processing on virtual models in different layers when rendering the virtual models, for example, in this embodiment, the rendering rejection of the game master camera can be realized by setting up a reflective layer.
Furthermore, when the game is run, the virtual model is not rendered according to the merged mapping (namely the target mapping) in the game master camera, but the virtual model is rendered according to the mapping before merging, and the target virtual model is rendered only according to the merged mapping in the reflection camera, so that the consumption of the rendering model is reduced.
After the scheme provided by the application is adopted to render the large cube in fig. 2, the corresponding value of Batches is 17, the value corresponding to TRIS is 9.8k, and the value corresponding to SetPass caps is 17. Therefore, after the number of the maps of the virtual model is reduced and the size of the maps is reduced, the combined maps are used for rendering the target virtual model, rendering data are obviously improved after the combined maps participate in reflection, the consumption required by the operation of a game engine is eliminated, the rendering consumption of the virtual model is reduced to half of the original consumption, and the rendering effect is not obviously reduced.
According to the scheme, the reflection rendering consumption can be reduced on the premise that the reflection effect is not influenced, the high-quality effect can be achieved, and the game running performance can be improved. Moreover, the scheme provided by the method has strong flexibility, and in practical application, the complexity of the virtual model material, the mapping precision and the like can be further reduced according to the effect requirement, so that the purpose of effectively reducing the rendering consumption is achieved. In addition, the virtual model in the game scene can be partitioned, blocked, integrated and optimized according to the size of the game scene, so that the number of simultaneously rendered faces is further reduced. Finally, the scheme provided by the application can flexibly adopt different scheme combinations according to the data of the actual QA test.
