Background
With the continuous development of computer technology, 3D games have become the mainstream of the market, and people experience games and simultaneously put higher requirements on the visual effect of the games. In the related art, in order to improve the visual effect of each character in a game, in the rendering process, a light source is separately set for each character model in addition to a scene light source.
However, although the method can improve the display effect of each character model after rendering, because each character model corresponds to a single light, when different character models are closer, the lights between the character models can affect each other, and further the overall visual display effect is affected.

The online game is highly popular among users due to the fact that the online game has high reality of game scenes and good appreciation and operability. Research shows that in order to meet the requirement of a user on higher visual effect, in the rendering process, besides a scene light source, a light source is usually set for each character model. However, although the method can highlight the dynamic visual effect of the character in the scene, because each character model corresponds to a single light, when different character models are closer, the lights between the character models can affect each other, and further the overall visual display effect is affected. In addition, as the number of lights is increased, the calculation pressure of a rendering pipeline is increased in the rendering process, so that the performance overhead becomes 9633, and the fluency of the game is further influenced.
Based on the research, the present disclosure provides an illumination rendering method, which includes firstly obtaining model initial illumination data corresponding to a target object model, the model initial illumination data being generated by user pre-configuration; then obtaining current position information of the target object model in a target scene and current lens information of a virtual camera, and processing the initial illumination data of the model based on the current position information and the current lens information to obtain model target illumination data; then generating first illumination information corresponding to the target object model based on the model target illumination data and the model initial illumination data; and finally, second illumination information of a scene light source of the target scene is obtained, and illumination rendering is carried out on the target object model based on the first illumination information and the second illumination information.
In the embodiment of the disclosure, since the first illumination information corresponding to the target object model is generated by the model initial illumination data pre-configured by the user, an independent light source is not required to be set for the target object model, and an independent illumination effect on the target object model can be realized, so that different models cannot be influenced mutually when approaching, and thus the model rendering effect can be improved. In addition, because the initial illumination data of the models can be shared among the models, in the process of generating the first illumination information of the models, part of the data only needs to be calculated once, and then the calculation pressure of a rendering pipeline can be reduced, namely, the rendering effect can be improved while the fluency of a rendering picture is ensured.
To facilitate understanding of the present embodiment, a detailed description is first given of an execution subject of the illumination rendering method provided by the embodiment of the present disclosure. The execution subject of the illumination rendering method provided by the embodiment of the disclosure is an electronic device. The electronic device may be a terminal device or a server. The terminal device may be a mobile device, a user terminal, a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like. The server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud storage, big data, an artificial intelligence platform and the like. In other embodiments, the illumination rendering method may also be implemented by the processor calling computer readable instructions stored in the memory.
The following describes the illumination rendering method provided in the embodiment of the present application in detail with reference to the accompanying drawings. Referring to fig. 1, a flowchart of an illumination rendering method provided in the embodiment of the present disclosure is shown, where the illumination rendering method includes the following steps S101 to S104:
s101, obtaining model initial illumination data corresponding to a target object model, wherein the model initial illumination data is generated by user pre-configuration.
Illustratively, the target object may be a virtual object in a virtual scene, the virtual object refers to things in the virtual scene, and the virtual object includes, but is not limited to, at least one of a virtual character, an animal, a plant, furniture, or a building. In the embodiment of the disclosure, the target object is a dynamic object which can be controlled in a virtual scene.
The virtual scene is a digital scene drawn by a computer through a digital communication technology, and comprises a two-dimensional virtual scene and a three-dimensional virtual scene, and information such as various material forms and spatial relationships appearing in the world can be simulated in a real way by using a virtualization technology. The three-dimensional virtual scene can display the form of the object more beautifully and can display the virtual reality world more intuitively. For example, the object objects in the three-dimensional virtual scene may include at least one of a terrain, a house, a tree, a character, and the like.
For the virtual scene, the three-dimensional simulation environment can be displayed through a computer three-dimensional graphic, the three-dimensional simulation environment can be displayed on a screen, and all target objects in the virtual scene can be described through three-dimensional scene data. For example, three-dimensional scene data may be loaded into a three-dimensional scene to present a three-dimensional simulation environment. Wherein the three-dimensional scene data may include at least one of model data, texture data, lighting data, terrain data, raster volume data, and the like.
In the embodiment of the present disclosure, the virtual scene is a scene for a player to control a target object to complete game logic, and the virtual scene may be a simulated environment of a real world, or a semi-simulated semi-fictional virtual environment, or a purely fictional virtual environment. The virtual environment may be sky, land, ocean, etc., wherein the land includes environmental elements such as desert, city, etc.
In addition, in the embodiment of the present disclosure, the illumination data includes, in addition to the scene light source, model initial illumination data corresponding to each model, and the model initial illumination data is generated by user pre-configuration. For example, a user may configure corresponding model initial illumination data for each model in an Excel table, and when the user uses the model initial illumination data, the data may be imported into a corresponding item.
Optionally, the model initial lighting data includes initial lighting direction data, initial lighting position data, initial lighting color data, initial lighting intensity data, and the like.
It can be understood that before rendering the target object model, a scene file that needs to establish a three-dimensional model needs to be acquired, a virtual scene is established according to the scene file, and then the target object model is displayed and processed in the virtual scene.
It should be noted that, in the embodiment of the present invention, when performing three-dimensional model processing, a three-dimensional model design tool may be first used to establish a model, and then a three-dimensional model development tool is used to further process the model, so as to finally obtain a required three-dimensional model.
Further, after the three-dimensional model of the target object is built, the three-dimensional model can be exported for further model processing by a three-dimensional model development tool. The embodiment of the invention mainly describes a process of rendering a three-dimensional model in a game process after the three-dimensional model is established.
S102, obtaining current position information of the target object model in a target scene and current lens information of a virtual camera, and processing the model initial illumination data based on the current position information and the current lens information to obtain model target illumination data.
The target scene may be the virtual scene, and it can be understood that, because the target object is a dynamic control object in the virtual scene, the position of the target object in the virtual scene may change, and when the target object is at different positions, the illumination effect received in the virtual scene is different, that is, when the light source in the virtual scene changes, the ambient illumination effect in the virtual scene may also change accordingly. In addition, as the position of the virtual object changes, the visual presentation content presented by the screen also differs.
Therefore, in some embodiments, it is necessary to obtain current position information of the target object model in a target scene and current lens information of the virtual camera, and process the model initial illumination data based on the current position information and the current lens information to obtain model target illumination data, so that the target illumination data matches with a current state of the target object model.
For example, the initial illumination direction data and the initial illumination position data in the model initial illumination data may be processed based on the current position information and the current lens information to obtain model target illumination data relative to the model and the virtual camera.
In one possible implementation, referring to fig. 2, regarding step S102, when the model initial illumination data is processed based on the current position information and the current lens information to obtain model target illumination data, the following steps S1021 to S1023 may be included:
and S1021, processing the initial illumination direction data based on the current lens orientation information of the virtual camera to obtain target illumination direction data.
It can be understood that, since the initial lighting direction data is of the camera space, the initial lighting direction data needs to be processed to obtain the lighting direction data of the world space for the subsequent lighting rendering. In some embodiments, the initial lighting direction data may be expressed in a unit vector direction relative to the virtual camera, and thus, when the current lens orientation information of the virtual camera is acquired, the current direction information of the unit vector direction in the camera space may be determined; and then converting the current direction information of the unit vector direction in the camera space into a world space according to the world space transformation matrix of the virtual camera to obtain illumination direction data of the world space, and taking the illumination direction data of the world space as the target illumination direction data. Therefore, the determination efficiency of the target illumination direction data can be improved.
And S1022, determining target illumination position data according to the target illumination direction data, the current position information of the target object model and the initial illumination position data.
For example, the initial illumination position data is represented by a preset distance relative to the virtual camera, and therefore, after obtaining the target illumination direction data, the illumination position data of the world space may be obtained by offsetting the preset distance by using the current position information of the target object model as a starting point according to the direction indicated by the target illumination direction data, and the illumination position data of the world space is used as the target illumination position data. Therefore, the determination efficiency of the target illumination position data can be improved. In this embodiment, the initial illumination position data is one offset value of the world space.
And S1023, obtaining the model target illumination data based on the target illumination direction data and the target illumination position data.
It can be understood that after the illumination direction data of the world space and the illumination position data of the world space are obtained, the model target illumination data can be generated.
In the embodiment of the disclosure, the initial illumination direction data is processed through the current lens orientation information of the virtual camera, and the initial illumination position data is adjusted through the current position information of the target object model, so that the adjusted illumination direction is relative to the virtual camera and the adjusted illumination position is relative to the target object model, but not relative to the scene, and since the rendering shader of each model only receives the model initial illumination data and the model target illumination data corresponding to the model itself, the first illumination information corresponding to the model itself is generated, and no other model is involved, therefore, it can be ensured that the illumination among the models cannot affect each other when different models approach each other.
S103, generating first illumination information corresponding to the target object model based on the model target illumination data and the model initial illumination data.
It is to be understood that the model initial lighting data comprises initial lighting color data and initial lighting intensity data in addition to the initial lighting direction data and the initial lighting position data. The initial illumination direction data and the initial illumination position data are processed through the processes to obtain target illumination direction data and the target illumination position data. Therefore, the target illumination direction data, the target illumination position data, the initial illumination color data and the initial illumination intensity data are combined to obtain the simulated light source corresponding to the target object model. It should be noted that the simulated light source is only for the target object model, and does not affect other models.
However, since there is a distance between the illumination position of the simulated light source and the target object model, in order to improve the real effect of illumination, the initial illumination intensity needs to be processed according to the current position information of the target object model and the target illumination position data to obtain target illumination intensity data based on the surface of the target object model, and then the target illumination direction data, the target illumination position data, and the target illumination intensity data are combined to obtain first illumination information corresponding to the target object model.
In one possible implementation, the rendering shader may determine the linear decrement of the initial illumination intensity based on the target object model table (9633), the distance to the illumination location, and obtain the model table (9633), the received target light intensity. That is, the rendering shader may determine, according to the current position information of the target object model and the target illumination position data, a distance between the target object model and the illumination position indicated by the target illumination position data; then determining a linear attenuation amount of the initial illumination intensity based on a distance between the target object model and the illumination position; and processing the initial illumination intensity according to the linear attenuation amount to obtain the target illumination intensity.
S104, second illumination information of a scene light source of the target scene is obtained, and illumination rendering is carried out on the target object model based on the first illumination information and the second illumination information.
In computer graphics, rendering refers to a process of projecting each object model in a three-dimensional scene into a digital image in two dimensions according to set environment, material, illumination and rendering parameters. The illumination rendering refers to illumination calculation processing performed on the target object model in the rendering process, so that the pixel points on the surface of the target object model have an illumination effect.
A light source in a virtual scene is a series of illumination data that can truly simulate the illumination effect of a light source in reality. Similar to real-world light sources, when a colored light source in a virtual scene is projected onto the surface of a colored object, the final rendered color depends on the reflection and absorption of light. Unlike real-world light sources, light sources in a virtual scene may be virtual light source nodes without shapes or contours. The light source in reality refers to an object that can emit light by itself and is emitting light, such as the sun, an electric lamp, a burning substance, and the like.
In some possible embodiments, the target object model may be rendered simultaneously based on the first illumination information and the second illumination information, resulting in an illumination rendering result. In yet other possible embodiments, referring to fig. 3, when performing illumination rendering on the target object model based on the first illumination information and the second illumination information, the following steps S1041 to S1043 may be further included:
s1041, performing first illumination rendering on the target object model based on the first illumination information to obtain a first illumination rendering result.
And S1042, performing second illumination rendering on the target object model based on the second illumination information to obtain a second illumination rendering result.
And S1043, fusing the first illumination rendering result and the second illumination rendering result to obtain an illumination rendering result of the target object model.
In the embodiment of the disclosure, the target object models are respectively rendered through the first illumination information and the second illumination information, and the rendering results are fused, so that the independent rendering effect of the models in a scene can be realized, and the overall rendering effect of a plurality of models in the scene can be improved.
It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
Based on the same technical concept, an illumination rendering device corresponding to the illumination rendering method is further provided in the embodiment of the present disclosure, and as the principle of solving the problem of the device in the embodiment of the present disclosure is similar to that of the illumination rendering method in the embodiment of the present disclosure, the implementation of the device may refer to the implementation of the method, and repeated details are not repeated.
