The following explains terms referred to in the present application.
A camera viewport: each scene requires a viewpoint when rendered, and the user is just observing the scene from the viewpoint position. 3D graphics systems typically use a scene camera (camera) to define the relative position and orientation of the user and the scene, as do cameras in our real world, cameras in the 3D world also have properties similar to the size of the field of view. The size of the field of view determines the perspective (e.g., distant scenes appear smaller). The various attributes of the camera combine to convey the final 3D scene rendered image to a 2D viewport (viewport), which is determined by a browser window or other element. The plane corresponding to the camera viewport is the rendered 2D image we finally see on the screen.
At present, when a picture in a scene is rendered, ray tracing calculation is directly performed on all objects in a renderable area, so that a large amount of calculation is required, and hardware pressure and power consumption of electronic equipment are high. Particularly in a game scene, in the rendering mode, the temperature of the electronic equipment can also rise rapidly when the user plays the game, so that the user experience is poor.
In view of the foregoing problems, embodiments of the present application provide a rendering method and a related apparatus, and the following describes embodiments of the present application in detail with reference to the accompanying drawings.

Referring to fig. 2a, fig. 2a is a schematic flowchart illustrating a rendering method according to an embodiment of the present disclosure. As shown in the figure, the rendering method includes the following steps:
s201, determining a target light source, of a plurality of light sources of a scene picture of a scene to be rendered, of which the distance from a reference position is smaller than a preset distance.
The reference position is a position of a main camera view port which represents a scene camera in a scene picture of the scene to be rendered, the scene camera is a control of a plurality of camera view ports in an editing interface of the scene to be rendered, and the main camera view port is a camera view port which simulates a user to observe a main viewpoint of the scene picture in the plurality of camera view ports. The main camera view port is a window responsible for rendering information of a main scene picture in a screen, and can be simply understood as a camera for presenting a three-dimensional space object picture. There may be multiple cameras for the content to be rendered, i.e. viewable from multiple viewpoints, and thus different camera viewports may be switched to by different scene cameras. The main camera view port can be set and changed according to the requirements of a user, namely, the view angle of the user is changed under the same scene, and the main camera view port is changed accordingly. For example, as shown in fig. 2b, fig. 2b is a schematic architecture diagram provided in this embodiment of the present application, where a position of a camera in the diagram is a reference position in this scheme, that is, a position of a main camera viewport, and when a target light source is determined, a relative position between each light source and the main camera viewport can be determined according to coordinates of the main camera viewport and coordinates of all light sources in the scene, so as to determine a daylight source. The target light source may include only one or a plurality of target light sources. The target light source may also be the light source closest to the reference position, for example, 3 light sources in fig. 2b, and according to the calculation, one target light source closest to the reference position may be determined, and only one target light source may be determined at this time.
S202, determining the target object irradiated by the target light source.
The target object is an object that can be irradiated by the target light source, that is, calculation such as ray tracing and the like is subsequently performed on the object, after the target light source is determined, the target light source and scene information that can be irradiated by the target light source need to be transmitted to a corresponding calculation engine for calculation, so as to realize rendering of a scene, and the scene information includes the target object.
In one possible example, the determining the target object illuminated by the target light source comprises: determining the irradiation range of the target light source; and determining a target object from the scene picture according to the irradiation range.
The illumination range can be determined according to the current scene and the type of the target light source.
Therefore, the target object is determined according to the irradiation range of the target light source, the target object can be quickly searched, and the rendering efficiency is improved.
In one possible example, the determining the illumination range of the target light source includes: determining a light source type of the target light source; and determining an illumination range according to the type of the light source.
The light source type may refer to a type of light source emitting light, such as a point light source, a parallel light, a spotlight, and the like, and may also refer to a type of object emitting light, such as a flashlight, a light bar, and the like. And the irradiation range is located in a range that can be rendered by the main camera viewport, as shown in fig. 2b, a region enclosed by a solid line and a dashed line in fig. 2b is a renderable region corresponding to the main camera viewport, and an intersection of the irradiation range corresponding to a target light source and the renderable range is a final irradiation range of the target light source.
Therefore, in the example, the types of the light sources are distinguished to determine the illumination range, so that the object to be rendered can be determined more accurately, and the calculation amount and the power consumption of the equipment are reduced.
In one possible example, the determining the illumination range according to the light source type includes: determining a light source brightness of the target light source; determining environmental information where the target light source is located; and determining an illumination range according to the light source type, the light source brightness and the environment information.
The environment information is used for indicating the state of the environment where the target light source is located, and the environment information may be used for indicating weather conditions, the located scene, and the like. For example, the current weather of the scene to be rendered is rainy or foggy, or the scene where the target light source is located is underwater, and the like, different pieces of environmental information may have a certain influence on the range that the target light source can illuminate. Specifically, determining the irradiation range according to the light source type, the light source brightness and the environment information includes: determining a theoretical illumination range according to the light source type and the light source brightness; determining the environmental category and the influence degree of the scene where the target light source is located according to the environmental information; and adjusting the theoretical irradiation range according to the influence degree to obtain the irradiation range. The different environmental categories have different degrees of influence on the irradiation range, for example, the irradiation ranges on a heavy fog day and a sunny day, and of course, when determining the degrees of influence, the degrees of influence are also determined according to the levels of the environmental categories, that is, for example, on a heavy fog day, and the degrees of influence corresponding to the different concentrations of fog in the environment are also different.
Therefore, in the example, the information such as the environment information of the scene to be rendered and the brightness of the target light source is fully considered, so that the irradiation range of the target light source is determined, the object to be rendered can be more accurately determined, the calculation amount and the power consumption of the equipment are reduced, and the fineness of the rendered picture is improved.
In one possible example, the light source type is a point light source, and the determining the illumination range according to the light source type, the light source brightness and the environment information includes: determining an illuminable radius according to the light source brightness and the environment information; drawing a sphere according to the illuminable radius by taking the point light source as a center to obtain a sphere space; and determining the range contained in the sphere space as the irradiation range.
A point light source refers to a light source that emits light uniformly from one point to a surrounding space. Therefore, for a point light source, the sphere is drawn by taking the illuminable range as the radius and taking the point light source as the center. The object in the ball is the object that needs to be tracked. Therefore, the radius and the coordinates of the point light source can be obtained, and the distance between the object traversing the scene and the point light source is judged. Of course, the illumination range also needs to be within the renderable range.
Therefore, in the example, the irradiation range of the target light source is accurately determined according to the characteristics of the light source, so that the object to be rendered can be more accurately determined, and the calculation amount and the power consumption of the device are reduced.
In one possible example, the determining the target object from the scene picture according to the illumination range includes: determining all objects in the scene to be rendered, which are positioned in the illumination range, as candidate objects; determining object coordinates of each candidate object; determining light source coordinates of the target light source; determining whether a target candidate object is shielded by other candidate objects according to the object coordinates and the light source coordinates, wherein the other candidate objects are the candidate objects except the target candidate object in all the candidate objects, and the target candidate object is any one of the candidate objects; and determining that the candidate object which is not occluded in all the candidate objects is the target object.
Whether an object located in the irradiation range of the target light source is shielded by other objects can be determined according to the coordinates of each object, and if the object is shielded, the object is an object which does not need to be subjected to ray tracing calculation. It should be noted that the term "blocking" herein means that the object is completely blocked, i.e., the light of the target light source cannot be irradiated to the object.
Therefore, in the example, the shielded object is determined according to the coordinates of the object, ray tracing calculation is not performed on the shielded object, the calculation amount and power consumption of the equipment can be reduced, and the rendering effect can be ensured at the same time.
In one possible example, the determining whether the target candidate object is occluded by other candidate objects according to the object coordinates and the light source coordinates includes: obtaining a coordinate set corresponding to the target candidate object according to the object coordinates of the target candidate object and the light source coordinates, wherein the coordinate set comprises a plurality of surrounding coordinates, and the position indicated by each surrounding coordinate is located on the path from the light of the target light source to the target object; determining whether object coordinates of the other candidate objects exist in the set of coordinates; if yes, acquiring a first shape of the other candidate object and a second shape of the target candidate object; determining a degree of coincidence of the first shape and the second shape on the path; and determining whether the target candidate object is shielded by other candidate objects according to the contact ratio.
Wherein, the path of the light ray to the target object may be a path of the light ray of the target light source to a center point of the target object. The first shape and the second shape are used to characterize the appearance of each candidate object, such as the length, width, height, etc. of the candidate object. The degree of coincidence can be used to characterize whether the target object candidate is completely occluded, for example, if the degree of coincidence is 100%, then the target object candidate is not the target object. As shown in fig. 2c, fig. 2c is a schematic diagram of an object occlusion provided in the embodiment of the present application. The object a in the figure is a target candidate, the object B is another candidate, the dotted line in the figure is a light path of the light emitted by the target light source, and it should be noted that only a part of the light path is shown in the figure. It can be seen that the light rays corresponding to the dashed lines 1 and 2 are the light ray boundaries theoretically irradiated by the target light source to the object a, that is, all coordinates in the interval corresponding to the two dashed lines are the surrounding coordinates in the coordinate set, and it can be seen that the coordinates of the object B are in the interval. And because the shape of the object B completely blocks the object a on the path, that is, the object a and the object B completely coincide on the path, the target light source cannot irradiate the object a through the object B, and therefore the object a is not the target object.
In a specific implementation, if for a target candidate object, coordinates of a plurality of other candidate objects exist in a corresponding coordinate set, the coordinates can be determined according to a position of each other candidate object relative to the target candidate object and a degree of coincidence between each other candidate object and the target candidate object, for example, there is also an object C, where the object C and the object B both have a certain occlusion on the object a, but the degree of coincidence between the object C and the object B is not 100%, at this time, it is necessary to determine positions of the object B and the object C relative to the object a, and determine whether the object a is simultaneously occluded by the object B and the object C according to the relative position. For example, if object B blocks a part of object a and object C blocks another part, object a is not the target object even if the degree of coincidence is not 100%.
Therefore, in the example, the shielded object is determined, ray tracing calculation is not carried out on the shielded object, the calculation amount and the power consumption of the equipment can be reduced, and the rendering effect can be ensured at the same time.
S203, performing ray tracing calculation on the target object to obtain a ray tracing calculation result.
Where ray tracing is used to generate images by tracing the path of light in pixel units in the image plane and simulating the effect of it encountering a virtual object, soft shadows, depth of field, motion blur, caustic, ambient light occlusion and indirect illumination can be produced, which works by tracing the path from the imaginary eye to each pixel in the virtual screen and calculating the color of the object visible through it. The ray tracing calculation result includes shadow, reflection, refraction, and ambient light mask map texture data. When performing ray tracing calculation on the target object, light source coordinates, color, intensity, and radiation range information of the target light source, and coordinate vertex and material information of the target object may be obtained first to perform ray tracing calculation.
And S204, creating a target image of the scene to be rendered according to the ray tracing calculation result.
In one possible example, the creating a target image of the scene to be rendered according to the ray tracing calculation result includes: performing rasterization calculation on the scene to be rendered to obtain a rasterization calculation result; and creating a target image of the scene to be rendered according to the ray tracing calculation result and the rasterization calculation result.
After the ray tracing calculation result is obtained, data obtained corresponding to the result can be merged into the original rendering pipeline, so that a technology which is closest to real rendering in theory and a universal rendering scheme are obtained, and the image effects of soft shadows, off-screen reflection and ambient light shielding are mainly shown. The original rendering pipeline comprises the step of carrying out rasterization calculation on a scene picture in a scene to be rendered, namely combining a ray tracing calculation result with data such as shadow, reflection, ambient light shielding mapping and the like obtained by rasterization to obtain a final rendering result.
Therefore, in the example, the light tracking calculation and the grating word calculation are simultaneously carried out on the scene to be rendered, so that the rendering effect can be ensured, and the calculation pressure and the power consumption of equipment hardware cannot be increased.
It can be seen that, in the embodiment of the present application, a target light source whose distance from a reference position is smaller than a preset distance is first determined among a plurality of light sources of a scene picture of a scene to be rendered, where the reference position is a position of a main camera view port characterizing a scene camera in the scene picture of the scene to be rendered, the scene camera is a control of a plurality of camera view ports in an editing interface of the scene to be rendered, the main camera view port is a camera view port simulating a user to observe a main viewpoint of the scene picture in the plurality of camera view ports, then a target object illuminated by the target light source is determined, then ray tracing calculation is performed on the target object to obtain a ray tracing calculation result, and finally a target image of the scene to be rendered is created according to the ray tracing calculation result. Therefore, the scene information of the light source needing to be subjected to light tracking calculation can be selectively determined, so that the number of light rays needing to be calculated is reduced, the hardware pressure and the power consumption are reduced, a better rendering picture can be obtained, and the use experience of a user is improved.
