Technical Field

The present application relates to the field of image rendering technologies, and in particular, to a rendering method and apparatus, a computer device, and a storage medium.

Background

Currently, it has become a trend to render an interface of an application running in a client by using cloud rendering resources. And the cloud rendering refers to rendering an interface of the application program, which is displayed by the terminal according to the operation requirement, by using the cloud rendering resources according to the operation of the terminal by the user when the application program is operated in the terminal.

In the related art, after receiving a rendering requirement sent by a client, a management node on the cloud may allocate, to the client, a rendering node that executes a rendering task of the client in rendering resources on the cloud according to the rendering requirement of the client, so that the rendering node renders an interface of an application program running in the client, and sends a rendering image to the client.

However, in the process of executing the rendering task by the rendering node, if the management node reallocates the rendering node to the client, the reallocated rendering node needs to execute the rendering operation again according to the rendering requirement of the client, which results in low rendering efficiency.

As can be seen from the above, in the rendering method, after receiving an instruction instructing execution of a rendering task generated by a client, a first rendering node obtains a state parameter generated when a second rendering node executes the rendering task, continues to execute the rendering task based on the state parameter, obtains a rendering image of the rendering task, and sends the rendering image to the client. In the rendering method, the state parameter is obtained by the second rendering node executing the rendering task in advance, so that on one hand, the first rendering node can directly execute the subsequent rendering operation according to the state parameter, and the first rendering node does not need to re-render according to the rendering instruction sent by the client to obtain the state parameter, the consumption of rendering resources of the first rendering node is reduced, the rendering efficiency is improved, on the other hand, the client does not need to send the rendering instruction to the first rendering node again, so that the client does not sense the scheduling of the rendering node for executing the rendering task of the client, and the user experience is ensured.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application provides a rendering method. In the rendering method, after receiving an instruction for instructing execution of a rendering task generated by a client, a first rendering node acquires a state parameter generated by a second rendering node for executing the rendering task, continues to execute the rendering task based on the state parameter, obtains a rendering image of the rendering task, and sends the rendering image to the client. In the rendering method, the state parameter is obtained by the second rendering node executing the rendering task in advance, so that on one hand, the first rendering node can directly execute the subsequent rendering operation according to the state parameter, and the first rendering node does not need to re-render according to the rendering instruction sent by the client to obtain the state parameter, the consumption of rendering resources of the first rendering node is reduced, the rendering efficiency is improved, on the other hand, the client does not need to send the rendering instruction to the first rendering node again, so that the client does not sense the scheduling of the rendering node for executing the rendering task of the client, and the user experience is ensured.

The rendering node is specifically a node used for rendering, and is generally provided with a Graphics Processing Unit (GPU), and the rendering node is configured to receive a rendering task sent by a client, process the rendering task according to the GPU, generate a rendering image, and send the rendering image to the client.

Fig. 1 is a schematic diagram of an implementation scenario related to a rendering method provided in an embodiment of the present application. As shown in fig. 1, the application scenario includes: a client 01 and at least two rendering nodes 02. A communication connection is established between the client 01 and each rendering node 02. The overall system in which the at least two rendering nodes 02 are located may be referred to as a rendering system.

The client 01 may be a mobile phone, a tablet computer, a personal computer, a virtual machine, a container, a laptop computer, a mobile phone, a multimedia player, an intelligent appliance, an artificial intelligence device, an intelligent wearable device, an electronic reader, an intelligent vehicle-mounted device, or an internet of things device. Rendering node 02 may be implemented by a physical device such as a physical server, a virtual machine or a virtual instance such as a container.

The user may use an application program on the client 01, and a display screen of the application program may be rendered by performing a rendering operation. When a user operates an application program, the client 01 may send a rendering instruction stream to the rendering node according to the operation, where the rendering instruction stream is used to instruct the client to display a picture according to the operation requirement of the user. The rendering node 02 may execute a corresponding rendering operation according to the rendering instruction stream, and provide a rendered screen obtained by rendering to the client, so that the client displays the rendered screen.

Moreover, the same rendering task of the client may be executed by different rendering nodes 02 in sequence, and after the rendering node 02 (e.g., the second rendering node) that executes the rendering task first, the state parameter obtained by executing the rendering task may be stored. After receiving the instruction indicating to execute the rendering task, the rendering node 02 (e.g., the first rendering node) that executes the rendering task later may obtain the state parameter, and continue to execute the rendering task according to the state parameter, so as to obtain a rendered image of the rendering task.

Alternatively, the implementation of storing the state parameters may be various. The following several realizations are exemplified below:

in a first implementation manner, different rendering nodes 02 that execute the same rendering task of the client in sequence may be deployed on the same host, and at this time, the state parameter may be stored in a storage medium of the host. The storage medium may be a hard disk or a memory.

In a second implementation manner, different rendering nodes 02 that execute the same rendering task of the client in sequence are deployed on different hosts, and at this time, the state parameter may be stored in a storage medium of the host where the rendering node 02 that executes the rendering task before is located, or the state parameter may also be stored in a storage medium of the host where the rendering node 02 that executes the rendering task after is located. The storage medium may be a hard disk or a memory.

In a third implementation manner, the state storage node for storing the state parameter may be deployed on a different host from the rendering node 02 that executes the rendering task first, and may be deployed on a different host from the rendering node 02 that executes the rendering task later. For example, the state storage node may be deployed on a host or cluster of hosts in the rendering system that do not have rendering node 02 deployed.

Corresponding to a third implementable manner of the state storage node, as shown in fig. 2, the rendering system further includes: state storage node 03. The state storage node 03 establishes a communication connection with each rendering node 02. The state storage node 03 may be implemented by a physical server.

Alternatively, the scheduling of rendering node 02 may be implemented by a management node. Accordingly, as shown in fig. 2, the rendering system further includes: and a management node 04. The management node 04 establishes a communication connection with each rendering node 02 and each client 01. The management node 04 may be implemented by a physical device such as a physical server, a virtual machine, a virtual instance such as a container, or the like.

The management node 04 may receive a rendering session request sent by the client 01, where the rendering session request is used to request the management node 04 to allocate, to the client 01, a rendering node 02 for executing a rendering task generated by the client 01. The management node 04 may indicate, to the client 01, a rendering node 02 for performing a rendering task of the client 01 according to the rendering session request. The client 01 may establish a network connection with the rendering node 02 indicated by the management node 04 according to the instruction of the management node 04, and send a rendering instruction stream to the rendering node 02 indicated by the management node 04 through the network connection, so that the rendering node 02 indicated by the management node 04 executes the rendering task of the client 01 according to the rendering instruction stream.

Further, as shown in fig. 2, the rendering system may further include: a gateway node 05, the gateway node 05 being connectable with the client 01, each rendering node 02 and the management node 04. The gateway node 05 may be implemented by an entity device such as a switch or a network address translation gateway, or a virtual instance such as a virtual machine or a container.

The network connection between rendering node 02 and client 01 may be implemented through the gateway node 05. At this time, after the management node 04 determines that the rendering node 02 for executing the rendering task of the client 01 is allocated to the client 01, the management node 04 needs to notify the gateway node of the allocated rendering node 02. Correspondingly, the indication sent by the management node 04 to the client 01 may indicate a gateway node to which the client 01 needs to connect, the client 01 may send a connection request to the indicated gateway node 05 according to the indication of the management node 04, and the gateway node 05 receives the connection request, and may connect the rendering node 02 allocated to the client by the management node 04 according to the notification of the management node 04, so as to implement network connection between the client 01 and the rendering node 02 allocated thereto.

Also, the gateway node 05 can provide a port mapping service. For example, the gateway node 05 may map a port of an Internet Protocol (IP) address of the gateway node 05 accessed by the external network to a port of an IP address of the subnet where the rendering node 02 is located, so as to improve the security of access.

Optionally, in the embodiment of the present application, the rendering system may have multiple deployment manners. For example, the rendering system may be deployed on a public network. Alternatively, the rendering system may be deployed in a cloud platform. Moreover, the cloud platform may be a cloud platform of a central cloud, a cloud platform of an edge cloud, or a cloud platform including a central cloud and an edge cloud, which is not specifically limited in the embodiments of the present application. And when the cloud platform is a cloud platform including a central cloud and an edge cloud, the rendering system may be partially deployed in the cloud platform of the edge cloud and partially deployed in the cloud platform of the central cloud.

When the rendering system is deployed in a cloud platform, the rendering node 02, the state storage node 03, the management node 04, and the gateway node 05 may be implemented by resources in the cloud platform, where the resources in the cloud platform include computing resources, storage resources, network resources, and the like. At this time, as shown in fig. 3, the rendering function provided by the rendering system to the client 01 can be abstracted into a rendering cloud service on the cloud platform by the cloud service provider and provided to the user. After a user purchases a rendering cloud service on the cloud platform, the cloud platform can execute a rendering task of a client used by the user by using resources in the cloud computing center.

The implementation procedure of the rendering method provided by the embodiment of the present application is described below with reference to an implementation scenario shown in fig. 2. For implementation processes of the rendering method in other implementation scenarios, please refer to the implementation process in the implementation scenario shown in fig. 2. Fig. 4 is a flowchart of a method of a rendering method provided in an embodiment of the present application, and as shown in fig. 4, an implementation process of the rendering method may include the following steps:

step 401, the client sends a first rendering session request to the management node.

The user can use an application program on the client, and a display screen of the application program can be rendered by executing a rendering operation. When a client uses a rendering system to render a display screen for the client, and a user generates an operation on an application program, the client may send a first rendering session request to a management node in the rendering system according to the operation, so as to request the management node to allocate, to the client, a rendering node for executing a rendering task generated by the client. Optionally, in order to facilitate the management node to allocate a more appropriate rendering node to the client, the first rendering session request may carry information about a screen that needs to be displayed by the application program. The operation of the user on the application program may trigger the first rendering session request through an Application Program Interface (API) or a User Interface (UI). The rendering task generated by the client refers to a rendering task generated by the client by running an application program or accessing a browser.

Step 402, the management node instructs the second rendering node to execute the client-generated rendering task based on the first rendering session request, and notifies the client of the execution of the client-generated rendering task by the second rendering node.

After receiving the first rendering session request sent by the client, the management node may obtain information such as load states of the multiple rendering nodes managed by the management node, and select a rendering node allocated to the client from the multiple rendering nodes according to the information such as the load states, for example, the rendering node allocated to the client by the management node is a second rendering node. And when the first rendering session request carries relevant information of a picture required to be displayed by the application program, the management node can also allocate a proper rendering node to the client according to the relevant information. After determining to allocate the second rendering node to the client, the management node notifies the second rendering node so that the second rendering node starts a related rendering program, and also notifies the client of the allocation result so that the client establishes network connection with the second rendering node. After receiving the first rendering session request sent by the client, the management node may authenticate the client according to the first rendering session request, and when the client passes the authentication, allocate a rendering node for the client.

Alternatively, the management node may allocate a rendering node for performing a rendering task generated by the client to the client according to a specified scheduling policy. For example, rendering nodes may be assigned to clients according to a load balancing policy and/or a similarity policy. For ease of understanding, the implementation process of assigning rendering nodes based on the similarity policy is described later.

And when the rendering node is implemented by a virtual instance such as a virtual machine or a container, if the management node determines that there is no virtual instance suitable for being allocated to the client in the existing virtual instance according to the first rendering session request, the management node may create the virtual instance and allocate the created virtual instance to the client.

After the management node notifies the client of the rendering task generated by the client executed by the second rendering node, the client may establish a connection request with the second rendering node to request to establish a network connection with the second rendering node. After the second rendering node establishes network connection with the client, a related rendering program of the second rendering node may be started. Or after the second rendering node receives the instruction of the management node to execute the rendering task generated by the client, the second rendering node starts a related rendering program of the second rendering node. The rendering program is generally applicable to a process executing a rendering operation, and the same process may use one Graphics Processing Unit (GPU) or multiple GPUs.

When the rendering system does not include a gateway node, the client may send a connection request to a second rendering node, which may establish a network connection with the client according to the connection request. When the rendering system comprises a gateway node, the client can send a connection request to the gateway node, after receiving the connection request, the gateway node can establish network connection with the client, determine the rendering node allocated to the client, and then establish network connection between the gateway node and the rendering node allocated to the client. The connection request may carry a connection identifier (e.g., a token), where the connection identifier is used to identify the identity of the client, and even the connection identifier is also used to identify a rendering session between the client and a rendering node to which the management node is assigned. After receiving the connection request, the gateway node verifies the client according to the connection identifier, and acquires the address of the rendering node allocated to the client, so as to establish network connection with the rendering node according to the address. Optionally, the gateway node may determine the address of the rendering node according to the information of the rendering node carried in the connection identifier. Alternatively, after determining to allocate a rendering node to a client, the management node may notify the gateway node of an address of the rendering node allocated to the client.

And step 403, the client sends a rendering instruction stream to the second rendering node.

If the client generates the rendering instruction stream according to the operation of the user, the client can send the rendering instruction stream to the second rendering node, so that the second rendering node executes corresponding rendering operation based on the rendering instruction stream. The rendering instruction stream carries relevant parameters for instructing to change the scene displayed in the client, for example, relevant parameters for instructing to change one or more of the following: modifying the spatial position and angle of the visual angle camera, setting the position of an object, loading a new object, adding a light source, changing the spatial position of the light source and the like.

And step 404, the second rendering node executes the rendering task generated by the client based on the rendering instruction stream, stores the state parameter of the rendering task obtained by executing the rendering task, and sends the rendering image obtained by rendering to the client.

And after receiving the rendering instruction stream sent by the client, the second rendering node can execute corresponding rendering operation according to the rendering instruction stream, wherein the rendering operation can generate state parameters of the rendering task and generate a rendering image of the rendering task according to the state parameters, and the second rendering node can send the rendering image to the client so that the client can display the rendering image. When the rendering system includes a gateway node, the rendering instruction stream sent by the client may be forwarded to the second rendering node via the gateway node, and the rendered image sent by the second rendering node may be sent to the client via the gateway node. The rendering target in the rendering task may be the whole scene that the client needs to display, or may be a single model in the scene, that is, the rendering of the second rendering node may be the whole scene, or may be a single model in the scene, which is not specifically limited in the embodiment of the present application.

The state parameter may be considered an intermediate product of the second rendering node from execution of the stream of rendering instructions to the time of the rendered image. In an implementation manner, the state parameter includes a rendering scene configuration parameter, where the rendering scene configuration parameter is used to indicate a configuration of a scene (such as a two-dimensional scene or a three-dimensional scene) that needs to be displayed by the client, and the rendering node can reconstruct the entire rendering scene according to the rendering scene configuration parameter. Optionally, the rendering scene configuration parameters include: and one or any combination of the position, the material information, the texture map information, the light source type, the light source position, the camera shooting position and angle and the data storage address of the rendering model in the rendering scene in the rendering task.

Further, the state parameters further include a rendering model parameter indicating a configuration of a rendering model from which the rendering node can reconstruct the entire rendering model. Optionally, the rendering model parameters include: one or any combination of the total number of vertices, the total number of triangle patches, and the colors of the rendering model in the rendering task.

Optionally, there are various implementation manners for storing the state parameters according to different implementation manners of the state storage node. For example, when the state storage node is deployed on a host on which the second rendering node resides, the second rendering node may store the state parameter in a storage medium of the host on which the second rendering node resides. For another example, when the state storage node is not deployed on the host on which the second rendering node is located, and when the state storage node is deployed on another host on which the rendering node is deployed, the second rendering node may send the state parameter to the other host, so as to store the state parameter in a storage medium of the other host. For another example, when the state storage node is deployed on a host or a host cluster in the rendering system where no rendering node is deployed, the second rendering node may send the state parameter to the host or the host cluster where no rendering node is deployed, and the state parameter is already stored in the storage medium on the host or the host cluster where no rendering node is deployed.

It should be noted that the rendering instruction stream received by the second rendering node may include a rendering instruction stream for rendering a plurality of images, and the second rendering node may store the state parameter immediately after obtaining the state parameter according to the rendering instruction stream for rendering any one of the images, or the second rendering node may store the obtained state parameter within a specified time according to the specified time, or the second rendering node may store all the state parameters obtained by executing the rendering task after completing the rendering task. For example, when a rendering task needs to be scheduled from the second rendering node to the first rendering node for execution, the second rendering node may store all state parameters obtained during the execution of the rendering task by the second rendering node after executing the rendering operation that needs to be executed according to the scheduling instruction.

In order to effectively continue to execute the rendering task according to the state parameters, the state parameters obtained by the second rendering node each time the rendering operation is executed need to be stored. In addition, in order to ensure the time sequence of the state parameters obtained according to the rendering instruction streams for rendering different images, the second rendering node may add tag information to the stored state parameters to identify the time sequence of the state parameters by using the tag information, so that the time sequences of the state parameters obtained according to the rendering instruction streams for rendering different images are not confused.

In addition, the second rendering node may encode the rendered image before sending the rendered image to the client, and send the encoded rendered image to the client. And, when the rendering image is an image frame in the video, the second rendering node also needs to encode one I frame. The encoding mode used by the second rendering node for encoding the rendered image may be determined according to an application requirement, and the embodiment of the present application does not specifically limit the encoding mode. In addition, the second rendering node needs to consider the frame rate of the client when encoding the rendered image and transmitting the encoded rendered image. For example, the second rendering node may encode the rendered image at a fixed frame rate (e.g., 30 frames per second) and send the encoded rendered image to the client, or the second rendering node may determine the frame rate to which encoding refers according to a change between every two adjacent rendered images.

The scenes of the rendering node executing the rendering task in the embodiment of the application comprise at least two scenes as follows:

in a first scenario, an application program runs in a client, the client needs to use rendering capability provided by a rendering node to provide images which need to be displayed in the running process of the application program for the client, and the client selects different images which need to be displayed according to different operations executed by the user at the client. For example, a certain game application is run in the client, and when a user performs different operations in the user interface of the game application, the images that the client needs to display are different. As shown in fig. 5, fig. 5 shows an image of a room just entered by a game character, where the image can be obtained by a user indicating the game character to enter the room in a user interface of a game application, a client sending a rendering instruction stream to a rendering node according to the indication of entering the room, and the rendering node executing a rendering operation according to the rendering instruction stream. As shown in fig. 6, fig. 6 shows an image in which a game character enters a room and moves forward in the room to a position near a couch, the image may be obtained by a user instructing the game character to move forward in the user interface shown in fig. 5, the client sends a rendering instruction stream to the rendering node according to the movement instruction, and the rendering node performs a rendering operation according to the rendering instruction stream.

Also, as shown in fig. 5 and 6, the state parameter may be a rendering scene configuration parameter for describing the game scene displayed in fig. 5 and 6, such as a rendering scene configuration parameter describing the following rendering scene: the tea table is placed against the wall, located in front of the visual angle, of the room, the tea table is placed right opposite to the sofa, a soldier squats in the center of the room, and the soldier holds the gun to make an aiming posture.

When the state parameters further include the rendering model parameters, as shown in fig. 5 and 6, the state parameters include the total number of vertices, the total number of triangle patches, and the color of each rendering model in the room, the door, the soldier, the gun, the sofa, the end table, and the floor of the room.

In a second scenario, an application program runs in a client, a user interface of the application program includes at least two parts, a first part of the at least two parts displays an initial image drawn by a user, the initial image is locally rendered by the client, so the definition is low, a second part of the at least two parts displays an image with higher definition, which is sent by a rendering node to the client according to the rendering of the initial image, wherein after the user performs a rendering operation in the first part, the client displays an image which is drawn by the rendering operation and is rendered locally but is less clear in the first part, generates a rendering instruction stream according to the drawing operation of the user, and then sends the rendering instruction stream to the rendering node, so that the rendering node performs the rendering operation according to the rendering instruction stream and feeds back the rendered image to the client.

Also, as shown in fig. 7, the state parameter may be a rendering scene configuration parameter for describing the wreath scene displayed in fig. 7, such as a rendering scene configuration parameter for describing the following rendering scenes: the multiple boughs are connected end to form a garland.

When the state parameters further include rendering model parameters, as shown in fig. 7, the state parameters include the number of flowering branches enclosing a rosette, the total number of vertices of each bouquet of flowering branches, the total number of triangular patches, and colors.

Step 405, the management node instructs to schedule the rendering task of the client from the second rendering node to the first rendering node for execution, and notifies the first rendering node and the second rendering node.

After the management node instructs the second rendering node to execute the rendering task generated by the client, the management node may continue to schedule the rendering node for executing the rendering task generated by the client to the client, for example, continue to determine the rendering node allocated to the client according to the specified scheduling policy of the management node, so as to optimize the resource utilization rate in the rendering system, or after the rendering task of the client is interrupted for some reason, the management node may reschedule the rendering task generated by the client, so as to continue to execute the rendering task. Also, the rendering node that the management node reschedules to the client may be the same or different than the rendering node that the management node previously scheduled to the client. For example, the rendering node that the management node reschedules to the client may be the first rendering node, at which point the management node may indicate to the first rendering node and the second rendering node that the rendering task for the client is scheduled from the second rendering node to the first rendering node.

The condition that the management node reschedules the rendering node executing the rendering task comprises the following steps: firstly, the running load of the second rendering node is too high, and the rendering task needs to be scheduled to other rendering nodes for execution so as to reduce the running load of the second rendering node and ensure the running performance of the second rendering node; secondly, the running load of the second rendering node is too low, all rendering tasks executed by the second rendering node can be scheduled to other rendering nodes for execution, and the second rendering node is closed, so that the resource utilization rate of the rendering system is improved; thirdly, the second rendering node fails to execute the rendering task continuously, and the rendering task needs to be dispatched to other rendering nodes for execution so as to ensure the normal execution of the rendering task; fourthly, the client does not send the rendering instruction stream to the second rendering node for a long time, so that the management node indicates that the rendering session between the second rendering node and the client is closed, even the management node allocates the second rendering node to other clients, and at this time, when the user reactivates the rendering session of the client, the rendering node needs to be scheduled for the client again.

When the rendering task of the client is scheduled from the second rendering node to the first rendering node for execution, the network connection between the client and the rendering node needs to be switched. When the rendering system includes a gateway node, the switching of the network connection between the client and the rendering node may be implemented by the gateway node, and the implementation manner includes: and maintaining network connection between the gateway node and the client, and switching the rendering node connected with the gateway node from the second rendering node to the first rendering node. In this way, the client does not perceive the switching of the network connection, and can realize the rescheduling of the rendering node under the condition that the client does not perceive. When the rendering system does not include a gateway node, the management node may notify the rendering node to which the client is assigned to become the first rendering node, so that the client switches its network connection with the rendering node to a network connection with the first rendering node.

And 406, the first rendering node acquires the state parameter of the rendering task.

After the first rendering node receives the instruction that the management node instructs to schedule the rendering task to the first rendering node for execution, the first rendering node may start a related rendering program and obtain a state parameter of the rendering task. Moreover, according to different implementation manners of the state storage node, there are also multiple implementation manners for the first rendering node to obtain the state parameter, and the following implementation manners are taken as examples to describe the following implementation manners:

in a first implementation manner, when a state storage node is deployed on a host or a host cluster in which no rendering node is deployed in a rendering system, a first rendering node acquires a state parameter from the state storage node, for example, from a storage medium of a host or a host cluster in which the state storage node is located.

In a second implementation manner, when the state parameter is stored on the host computer where the first rendering node is located, the first rendering node may obtain the state parameter from a storage medium of the host computer where the first rendering node is located. At this time, the second rendering node may be deployed on the same host as the first rendering node.

In a third implementation, when the state parameter is stored on another host that is not deployed with the first rendering node, the first rendering node may obtain the state parameter from a storage medium of the other host. For example, when the first rendering node and the second rendering node are deployed on different hosts and the second rendering node stores the state parameter on the host on which the second rendering node is located, the first rendering node may obtain the state parameter from a storage medium of the host on which the second rendering node is located. For another example, when the state parameter is stored on another host that does not deploy the first rendering node and the second rendering node, the first rendering node may acquire the state parameter from a storage medium of the other host.

It should be noted that, when the first rendering node and the second rendering node are deployed on the same host, the first rendering node may not obtain the state parameter stored by the second rendering node, and the first rendering node may restore the data on the host where the first rendering node is located to be available, and then continue to execute the rendering task according to the data restored to be available.

And 407, the first rendering node continues to execute the rendering task based on the state parameter to obtain a rendering image of the rendering task, and the rendering image is sent to the client.

After the first rendering node obtains the state parameter of the rendering task, model data can be loaded, model parameters and camera parameters can be set, and the like, based on the state parameter, so that the rendering task can be continuously executed. Since the amount of data involved in the process is large, and when the state parameters do not include the model configuration parameters, the first rendering node needs to obtain the model configuration parameters from other storage systems, for example, the model configuration parameters need to be obtained from a network file system of the object storage, and therefore the process may need to be completed by performing one or more processes. And the first rendering node and the second rendering node can simultaneously execute the rendering tasks, and send the rendering images to the client by using the second rendering node so as to ensure the quality of the rendering service provided for the client until the first rendering node can stably execute the rendering tasks, and then switch to the first rendering node to send the rendering images to the client.

In addition, in the process of executing the rendering task by the first rendering node, the client may also send a newly generated rendering instruction stream to the first rendering node, and after receiving the newly generated rendering instruction stream, the first rendering node may execute a rendering operation according to the newly generated rendering instruction stream, so as to obtain a rendering image that the client needs to display. Meanwhile, the first rendering node may also store the state parameters obtained in the process of performing the rendering operation for subsequent use.

In addition, the second rendering node may encode the rendered image before sending the rendered image to the client, and send the encoded rendered image to the client. And, when the rendering image is an image frame in the video, the second rendering node also needs to encode one I frame. The encoding mode used by the second rendering node to encode the rendered image may be determined according to application requirements, and is not specifically limited in the embodiment of the present application.

As can be seen from the above, in the rendering method provided in the embodiment of the present application, after receiving an instruction instructing execution of a rendering task generated by a client, a first rendering node obtains a state parameter generated when a second rendering node executes the rendering task, continues to execute the rendering task based on the state parameter, obtains a rendering image of the rendering task, and sends the rendering image to the client. In the rendering method, the state parameter is obtained by the second rendering node executing the rendering task in advance, so that on one hand, the first rendering node can directly execute the subsequent rendering operation according to the state parameter, and the first rendering node does not need to re-render according to the rendering instruction sent by the client to obtain the state parameter, the consumption of rendering resources of the first rendering node is reduced, the rendering efficiency is improved, on the other hand, the client does not need to send the rendering instruction to the first rendering node again, so that the client does not sense the scheduling of the rendering node for executing the rendering task of the client, and the user experience is ensured.

The following describes an implementation process of allocating rendering nodes by a management node based on a similarity policy. As shown in fig. 8, the implementation process includes the following steps:

step 801, the management node obtains description information of a rendering target in a rendering task of the client.

The description information of the rendering target is used for indicating the rendering target in the rendering task. In different implementation scenarios, the implementation manner of the description information is different. The following two implementation scenarios are taken as examples to illustrate the description information of the rendering target:

in a first implementation scenario, a client may instruct to access a browsing type file (also referred to as a read-only browsing type file), at this time, an image to be displayed in a display interface of the client is a page of the browsing type file, and a rendering task sheet renders a page targeted for the browsing line file. In the first scenario, the description information of the rendering target is information for describing the browsing type file. For example, when the rendering target is a browsing type file, the description information of the rendering target is the storage address of the browsing type file. The rendering session request sent by the client may carry description information of the browsing-type file, and the rendering session request is used to request the management node to allocate, to the client, a rendering node for executing a rendering task generated by the client.

In a second implementation scenario, a user operates the client to drive a scene to be displayed in the client to change, at this time, an image to be displayed on a display interface of the client is a picture of the changed scene, and the client sends a rendering instruction stream according to the user operation, so that the rendering node executes a rendering operation according to the rendering instruction stream to obtain the scene. In the second scene, the description information of the rendering target is information for describing the rendered scene. For example, when the rendering target is a game scene of a game application running in the client, the description information of the rendering target is information of the game scene obtained by the rendering node executing the rendering operation according to the rendering instruction stream.

Step 802, the management node obtains the similarity between the rendering target described by the description information and the rendering target of the rendering task executed by each rendering node managed by the management node.

Optionally, the acquiring, by the management node, a similarity between the rendering target described by the description information and a rendering target of a rendering task executed by each rendering node managed by the management node includes: the management node respectively obtains the total number of the same rendering model included in the rendering target of the rendering task executed by each rendering node managed by the management node and the rendering target described by the description information, and determines the similarity based on the total number. For convenience of description, the total number of the same rendering model included in the rendering target of the rendering task executed by any one rendering node and the rendering target described by the description information is referred to as the total number of the same rendering model corresponding to any one rendering node.

For example, for the rendering node a managed by the management node, the similarity between the rendering target described by the description information and the rendering target of the rendering task executed by the rendering node a may be determined according to the total number A1 of rendering models included in the rendering target of the rendering task executed by the rendering node a and the total number A2 of the same rendering models corresponding to the rendering node a.

As an implementation manner, the management node may obtain at least one parameter of the total number of vertices, the total number of triangular patches, and the size of the occupied storage space of each same rendering model included in the rendering target of the rendering task executed by the any rendering node and the rendering target described by the description information, and determine the similarity based on the at least one parameter and the total number of the same rendering models corresponding to the any rendering node. For example, when determining the similarity, the at least one parameter may be used to weight a total number of the same rendering models corresponding to the any rendering node, so as to obtain a more accurate similarity.

Optionally, determining whether the two models are the same rendering model may be implemented in a variety of ways. For example, two rendering models may be considered the same rendering model when they are from the same network storage location (e.g., the Uniform Resource Locators (URLs) of the two rendering models are the same). Alternatively, two rendering models may be considered to be the same rendering model when they have the same model identification (e.g., message digest algorithm 5, MD5) value).

And step 803, the management node indicates the rendering nodes with the similarity greater than the specified similarity threshold, and the rendering tasks of the client are executed.

When the similarity between the rendering target described by the description information and the rendering target of the rendering task executed by a certain rendering node is greater than an execution similarity threshold, the same data which needs to be rendered by the rendering target and the rendering target is more, the rendering node with the similarity greater than a specified similarity threshold is indicated to execute the rendering task of the client, so that at least two rendering tasks with the greater similarity can share rendering resources, at least part of rendering operations in different rendering tasks can be realized by using the same resource, repeated rendering operations are reduced, and the consumption of the rendering resources is reduced, for example, the consumption of video memory resources and computing resources for rendering is reduced, so that the limited rendering resources are utilized to provide services for more users, and the utilization rate of the rendering resources is improved.

The rendering nodes with the similarity greater than the specified similarity threshold may exist in multiple numbers, and at this time, one rendering node may be selected from the multiple rendering nodes according to a specified policy, and the selected rendering node is instructed to execute the rendering task of the client. The specified policy can be set according to application requirements. For example, the rendering node with the lowest load may be selected from the plurality of rendering nodes, which is not specifically limited in the embodiment of the present application. And, the specified similarity threshold can also be determined according to application requirements.

Moreover, when the rendering nodes are allocated, the load state of the rendering nodes also needs to be considered, for example, the management node indicates the rendering node with the similarity greater than a specified similarity threshold, and the rendering task of the client is executed, which may specifically include: the management node acquires the load state of the rendering node with the similarity larger than the specified similarity threshold, and when the load state of the rendering node with the similarity larger than the specified similarity threshold meets the specified load condition, the management node indicates the rendering node with the similarity larger than the specified similarity threshold to execute the rendering task of the client.

Therefore, the rendering node with the similarity greater than the specified similarity threshold is used for executing the rendering task of the client, at least part of rendering operations in different rendering tasks can be realized by using the same resource, repeated rendering operations are reduced, consumption of rendering resources is reduced, service is provided for more users by using the limited rendering resources, and the utilization rate of the rendering resources is improved.

Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is covered by the protection scope of the present application, and thus the detailed description thereof is omitted.
