Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic view illustrating an interactive scene of a live broadcast system provided in the present application, which may be a live broadcast platform for live broadcast such as internet in some embodiments. The live broadcast system can comprise a server, a live broadcast initiating terminal and a live broadcast receiving terminal, wherein the server can be communicated with the live broadcast receiving terminal and the live broadcast initiating terminal respectively, and the server can provide live broadcast service for the live broadcast receiving terminal and the live broadcast initiating terminal. For example, the anchor may provide a live stream online in real time to the viewer through the live initiator and transmit the live stream to the server, and the live receiver may pull the live stream from the server for online viewing or playback.
In some implementations, the live receiver and the live initiator may be used interchangeably. For example, a anchor of a live originator may use the live originator to provide live video services to viewers, or as viewers to view live video provided by other anchors. For another example, a viewer at a live receiver may also use the live receiver to watch live video provided by a concerned anchor, or serve as the anchor to provide live video services to other viewers.
In some embodiments, the live receiver and the live initiator may include, but are not limited to, a mobile device, a tablet computer, a laptop computer, or any combination of two or more thereof. In some embodiments, the mobile device may include, but is not limited to, a wearable device, a smart mobile device, an augmented reality device, and the like, or any combination thereof. In some embodiments, the smart mobile device may include, but is not limited to, a smartphone, a Personal Digital Assistant (PDA), a gaming device, a navigation device, or a point of sale (POS) device, or the like, or any combination thereof.
In addition, in some possible embodiments, there may be zero, one, or more live receivers and live initiators, only one of which is shown in fig. 1, accessing the server. The live broadcast receiving end and the live broadcast initiating end can be provided with internet products for providing internet live broadcast services, for example, the internet products can be application programs APP, Web webpages, applets and the like used in a computer or a smart phone and related to the internet live broadcast services.
In some embodiments, the server may be a single physical server or a server group consisting of a plurality of physical servers for performing different data processing functions. The set of servers can be centralized or distributed (e.g., the servers can be a distributed system). In some possible embodiments, such as where the server employs a single physical server, the physical server may be assigned different logical server components based on different live service functions.
It will be appreciated that the live system shown in fig. 1 is only one possible example, and that in other possible embodiments of the present application, the live system may also include only some of the components shown in fig. 1 or may also include other components.
In a scene such as live network shown in fig. 1, some rendering objects such as bubbles and balloons may be rendered in a live image based on technologies such as AR (Augmented Reality) by using tools such as ARKit or arc, so as to increase live content in the live image and improve live effects.
The live broadcast image generally shows a scene picture in a 3D space, and as shown in fig. 2, taking a special effect of rendering bubbles in the live broadcast image as an example, the bubbles can be rendered in the live broadcast image in a form of rendering 2D patches, so that the data amount processed when the bubbles are rendered is reduced, and processing resources are saved.
However, in some possible scenarios, the viewing angle of the terminal device may change during the process of displaying the live broadcast image by the terminal device, for example, when the terminal device is a mobile phone operated by a user, the shooting viewing angle of the mobile phone may also change during the process of the user holding the mobile phone to move the shooting direction; however, in this process, the rendered 2D tile may not change with the change of the viewing angle of the terminal device, so that the rendered bubble may have some abnormal display contents such as a sharp edge in the live broadcast image, resulting in a poor rendering effect.
Therefore, based on some defects existing in the rendering scheme, a possible implementation manner provided by the present application is: the rendering orientation information of the object to be rendered is obtained based on the visual orientation information by obtaining the visual orientation information of the virtual vision, so that the object to be rendered is rendered according to the rendering orientation information; therefore, the object to be rendered is always displayed towards the visual point, abnormal display content cannot be generated in the rendered picture, and the rendering effect is improved.
Referring to fig. 3, fig. 3 shows a schematic block diagram of an electronic device 100 provided in the present application, and in some embodiments, the electronic device 100 may include a memory 101, a processor 102, and a communication interface 103, and the memory 101, the processor 102, and the communication interface 103 are electrically connected to each other directly or indirectly to implement data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.

It will be appreciated that the configuration shown in fig. 3 is merely illustrative and that electronic device 100 may include more or fewer components than shown in fig. 3 or have a different configuration than shown in fig. 3. The components shown in fig. 3 may be implemented in hardware, software, or a combination thereof.
The following schematically illustrates an object rendering method provided by the present application, with the electronic device 100 shown in fig. 3 as an exemplary execution subject.
It can be understood that, in some possible scenarios of the present application, the electronic device 100 may serve as a live broadcast initiating terminal in fig. 1, and a main broadcast at a live broadcast initiating terminal side interacts with the live broadcast initiating terminal, so that the live broadcast initiating terminal executes the object rendering method provided by the present application, and a live broadcast code stream obtained after rendering is sent to a server, so that a live broadcast receiving terminal can pull the live broadcast code stream from the server and play a rendered live broadcast image after decoding.
Or, in some other possible scenarios in the present application, the electronic device 100 may also be used as the server in fig. 1, where the server executes the object rendering method provided in the present application by receiving a rendering request sent by a live broadcast initiating terminal or a live broadcast receiving terminal, so as to obtain a rendered live broadcast image; and sending the rendered live broadcast image to at least one of the live broadcast receiving end and the live broadcast initiating end, so that the rendered live broadcast image can be displayed by at least one of the live broadcast receiving end and the live broadcast initiating end.
Still alternatively, in some other possible scenarios in the present application, the electronic device 100 may also be used as a live broadcast receiving end in fig. 1, where the live broadcast receiving end pulls a live broadcast code stream from a server and decodes the live broadcast code stream to obtain a live broadcast image, and in a process of displaying the live broadcast image on a display interface of the live broadcast receiving end, the object rendering method provided in the present application may be executed by receiving instruction information of a user, so as to render the live broadcast image, and the rendered live broadcast image is displayed on the display interface of the live broadcast receiving end.
Referring to fig. 4, fig. 4 shows an exemplary flowchart of an object rendering method provided in the present application, and as a possible implementation, the object rendering method may include the following steps:
And 203, obtaining rendering orientation information of the object to be rendered based on the visual orientation information.
And step 205, rendering the object to be rendered according to the rendering azimuth information.
In some embodiments, in the process of executing the object rendering method provided by the present application, the electronic device may utilize an kit or an arcre tool to create a virtual visual point in advance, for example, to virtually a 3D virtual camera in a 3D space, and use a position of the 3D virtual camera in the 3D space as the virtual visual point, where the virtual visual point may be used to simulate a viewing angle of a user; taking a mobile phone operated by a user as the above electronic device as an example, in some possible implementations, the position coordinates of the mobile phone in the 3D space may be used as the position coordinates of the virtual visual point in the 3D space.
In a scene, for example, in which the position coordinates of the mobile phone in the 3D space are used as the position coordinates of the virtual visual points, the electronic device may obtain visual orientation information of the virtual visual points based on the posture information of the mobile phone; for example, assume that the current posture information of the mobile phone in the display scene is: the included angle with the ground is 30 °, the visual orientation information of the virtual visual point may be: at an angle of 30 deg. to the ground in 3D space.
In addition, the electronic device may also virtualize a particle emitter in the 3D space, and the particle emitter may be used to virtualize an emission source of the object to be rendered; such as in a rendered bubble special effect scene such as that shown in fig. 1, the particle emitter may be used to generate a bubble effect, and the bubble may move along a preset trajectory after being generated from the particle emitter.
It will be appreciated that in a scene such as that described above, to reduce the amount of data processed in rendering the bubble effect, the above-described bubble effect may be rendered in the form of a 2D tile; accordingly, when the electronic device virtualizes the particle emitter, a 2D particle emitter can be virtualized, so that a bubble special effect in a 2D form is generated.
In some embodiments, after the electronic device generates a rendering object such as a bubble using, for example, the 2D example transmitter described above, based on the obtained visual orientation information, rendering orientation information of the rendering object may be obtained, and the rendering orientation information may be used to indicate orientation information of the rendering object when the rendering object is oriented to the virtual visual point.
Next, the electronic device may render the object to be rendered according to the rendering orientation information of the obtained object to be rendered; for example, in the live broadcast scene illustrated in fig. 1, the object to be rendered is rendered into the live broadcast image according to the rendering orientation information, so that when the rendered live broadcast image is displayed, the rendering object is always displayed toward the visual point, and abnormal display contents such as a sharp edge in fig. 2 are not displayed, thereby improving the rendering effect.
In some embodiments, for a virtual visual point created in advance by the electronic device, the electronic device may create a visual coordinate system based on the virtual visual point, an origin of the visual coordinate system may be a position coordinate of the virtual visual point in the 3D space, an X-axis of the visual coordinate system is forward, which may be a viewing angle direction of the virtual visual point, a Y-axis of the visual coordinate system may point to a direction perpendicular to the X-axis and parallel to a horizontal plane, and a Z-axis of the visual coordinate system may be perpendicular to a plane formed by the X-axis and the Y-axis. And, the electronic device may calculate a view matrix, which may be used for coordinate transformation of a visual coordinate system of the virtual visual point and a world coordinate system in the 3D space.
Based on this, in the process of executing step 203, since the view angle of the view matrix and the model matrix are in relative positions in the world coordinate system, the electronic device may calculate the visual model matrix corresponding to the visual orientation information in a manner of, for example, obtaining an inverse matrix based on the view matrix; the virtual visual point may be used to simulate a viewing angle of a user, and the parameter in the visual model matrix may be used to indicate visual orientation information of the virtual visual point, such as orientation information, position information, and the like of the virtual visual point in a 3D coordinate system.
Next, the electronic device may calculate rendering orientation information of the object to be rendered when the object is oriented to the virtual visual point according to the obtained visual model matrix.
It should be noted that, with reference to the example of fig. 5, in some possible scenarios, the rendering position information of the object to be rendered may have the same parameters as the visual position information of the virtual visual point, for example, when the object to be rendered is located on the X axis of the visual coordinate system in the 3D space, the included angle between the object to be rendered and the ground is equal to the included angle between the virtual visual point and the ground; of course, in some other scenes, when the object to be rendered is not located on the X axis of the visual coordinate system in the 3D space, the included angle between the object to be rendered and the ground is not equal to the included angle between the virtual visual point and the ground.
In addition, in a scene in which bubbles are taken as objects to be rendered, for example, the electronic device may render the bubble effect in the form of a 2D tile in order to reduce the amount of data processed in rendering. For the exemplary rendering object of the bubble, the display effect of the rendering object in the live image is a generally circular area; therefore, based on this characteristic, the electronic device can determine a rendering control point in the bubble and also control the display area of the bubble in the live image; for example, the electronic device may select a center point of the bubble as a rendering control point according to a configuration parameter obtained in advance; alternatively, the electronic device may select a screen vertex of the bubble in the live image as the rendering control point.
Based on this, in some embodiments, in the process of executing step 205, the electronic device may first calculate the control point coordinates of the object to be rendered according to the rendering orientation information, where the control point coordinates may be used to indicate the coordinates of the rendering control point of the object to be rendered, such as the coordinates of the center point of the bubble or the coordinates of the vertex of the bubble.
Next, the electronic device may render a rendering display patch of the object to be rendered at a rendering control point based on the rendering orientation information; for example, as shown in connection with fig. 6, the electronic device may render a 2D tile of the bubble at a rendering control point to exhibit a bubble effect in the live image.
In addition, in the live webcasting scene illustrated in fig. 1, for example, in order to enable the user to normally view the rendered bubbles without viewing the abnormal display content illustrated in fig. 2 in the process of viewing live webcasting through different viewing angles, the electronic device may further render the rendering display tile of the object to be rendered in at least one visual expansion direction corresponding to the virtual visual point based on the rendering control point in the process of executing the object rendering method provided by the present application.
That is to say, in some scenes, when the electronic device executes the object rendering method provided by the present application, not only a rendering display patch of the object to be rendered may be rendered in a direction in which a rendering control point faces a virtual visual point, but also the rendering display patch of the object to be rendered may be rendered in at least one visual expansion direction corresponding to the virtual visual point; for example, based on the constructed visual coordinate system, the electronic device may render one rendering display patch along the positive direction and the negative direction of the X axis and the positive direction and the negative direction of the Y axis of the visual coordinate system; as such, even if the user views the rendered object from a different perspective, abnormal display contents such as a sharp edge as exemplified in fig. 2 are not generated.
In addition, in some embodiments, in the process that the electronic device renders the rendering display patch of the object to be rendered in at least one visual expansion direction corresponding to the virtual visual point, the electronic device may also perform rendering according to a preset spatial distance parameter; for example, in combination with the live broadcast scene illustrated in fig. 1, the electronic device may scale the display interface parameter according to a preset ratio to form a spatial distance parameter based on the display interface parameter (for example, the width and the height of the display interface) of the terminal device, so that the electronic device may render the rendering display patch of the object to be rendered in at least one visual expansion direction corresponding to the virtual visual point according to the spatial distance parameter.
It can be understood that, in some embodiments, the preset spatial distance parameter may be calculated by obtaining a display interface parameter for the electronic device, or may be sent by the electronic device receiving another device, or received by a user; as long as the electronic device can obtain a spatial distance parameter before executing the object rendering method provided by the present application, so as to execute the step of rendering the rendering display patch of the object to be rendered in at least one vision expansion direction corresponding to the virtual vision point.
Accordingly, referring to fig. 7 based on the same inventive concept as the object rendering method provided in the present application, fig. 7 illustrates an exemplary structural block diagram of an object rendering apparatus 300 provided in the present application, where the object rendering apparatus 300 may include a processing module 301 and a rendering module 302.

the processing module 301 is further configured to obtain rendering orientation information of the object to be rendered based on the visual orientation information; the rendering orientation information is used for indicating the orientation information of the object to be rendered when the object to be rendered faces the virtual visual point;
and the rendering module 302 is configured to render the object to be rendered according to the rendering orientation information.
