Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] The rendering method of the cloud desktop provided in the embodiment of the present application can be applied in a server or in a terminal with strong computing power.

[0048] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0049] Figure 1 A flowchart of a cloud desktop rendering method provided in an embodiment of the present application is shown below. Figure 1 As shown, the method may include:

[0050] Step S110, receiving a rendering request sent by a target cloud desktop connected to the server when running a target 3D program; and using a rendering main process corresponding to the target cloud desktop as a target rendering main process.

[0051] In an embodiment of the present application, a server can be connected to multiple cloud desktops, and multiple physical graphics cards are arranged on the server; any cloud desktop can run at least one 3D program; the cloud desktop that is running the 3D program is taken as the target cloud desktop, and the 3D program running on the target cloud desktop is taken as the target 3D program; a rendering proxy component is pre-deployed on the target cloud desktop; specifically, the target cloud desktop and the target 3D program can be one or more; the target cloud desktop and the server transmit instructions and data through serial ports and shared memory.

[0052] In an embodiment of the present application, the server sets a rendering main process for the target cloud desktop; each rendering main process sets a rendering sub-process for the target 3D program; the server can simultaneously receive multiple rendering requests sent by multiple target cloud desktops, and can also simultaneously receive multiple rendering requests generated when different target 3D programs sent by a target cloud desktop are running simultaneously.

[0053] In an embodiment of the present application, when the cloud desktop runs a target 3D program, the target 3D program will generate an initial rendering request based on the rendering configuration file and the target resources required for rendering itself.

[0054] In the prior art, one cloud desktop corresponds to an actual physical graphics card. When a 3D program is running, a rendering request is generated based on the rendering configuration file and the required resources, and the device driver interface in the user mode driver (UMD) is called. At the same time, the physical graphics card of the terminal where the 3D program is located is used in conjunction with the kernel mode driver (KMD). At this time, even if the physical graphics card has idle graphics card resources, it can no longer be called by other cloud desktops of the terminal. When all the graphics card resources of the physical graphics card cannot meet the needs of the 3D program, a performance bottleneck will occur in the 3D program.

[0055] In an embodiment of the present application, in order to solve the above-mentioned problems existing in the prior art, a rendering proxy component is pre-deployed for each target cloud desktop; when the target cloud desktop runs the target 3D program, the rendering proxy component intercepts the initial rendering request that the target 3D program expects to send to the physical graphics card of the terminal where the 3D program is located; at the same time, the rendering proxy component generates a rendering request based on the identifier of the target 3D program, the rendering configuration file and the target resources, and sends the rendering request to the target cloud desktop; the target cloud desktop sends the received rendering request to the server connected to the target cloud desktop using the serial port and shared memory.

[0056] This application intercepts the initial rendering request sent by the target 3D program, thereby preventing the target 3D program from calling the physical graphics card of the terminal where it is located for rendering; then uses the rendering proxy component to package the target 3D program's identifier and the initial rendering request to generate a new rendering request, and uses the target cloud desktop to send it to the server, thereby using the server's graphics card to complete the rendering task of the target 3D program, and thus the rendering calculation of the target 3D program is executed on the server side.

[0057] In an embodiment of the present application, the rendering proxy component is implemented by customizing UMD and KMD through OpenGL and DirectX proxy technology; the rendering proxy component is used to completely take over the rendering work of the 3D program running on the cloud desktop through customized umd and kmd, and implement the underlying call of each rendering API; the present application uses the underlying device driver interface (DDI) of the OpenGL and DirectX rendering interface to not only ensure that the application running on the cloud desktop can seamlessly transfer the rendering task to the server for execution, but also ensure compatibility and performance.

[0058] In an embodiment of the present application, an initial rendering request includes a rendering configuration file and target resources required for rendering a target 3D program; the rendering request includes an identifier of a target 3D program, a rendering configuration file of the target 3D program, and target resources required for rendering the target 3D program; wherein the rendering configuration file is used to indicate a process for rendering the target 3D program; and the target resources include target sub-resources required for each process of rendering the target 3D program.

[0059] Step S120: Send the rendering request to the target rendering main process, and allocate graphics card resources with the same size as the target resources from the pre-built graphics card resource pool to the target rendering main process.

[0060] In an embodiment of the present application, since a target cloud desktop may run multiple target 3D programs at the same time, that is, there are multiple parallel target rendering sub-processes under the target rendering main process, the sum of the target resources required by all the target rendering sub-processes of the target cloud desktop is first determined, and the graphics card resources are divided; then the target rendering main process divides the overall graphics card resources to each target rendering sub-process according to the target resources required by each target 3D program.

[0061] In an embodiment of the present application, sending a rendering request to a target rendering main process includes: sending an identifier of a target 3D program and a rendering configuration file of the target 3D program to the target rendering main process.

[0062] In an embodiment of the present application, in order to more efficiently and reasonably manage all graphics card resources of the server, a graphics card resource pool is constructed based on the idle graphics card resources of each graphics card set on the server, which not only realizes the unified management of each graphics card of the server, but also can improve the utilization rate of the graphics card resources of each graphics card.

[0063] In an embodiment of the present application, the overall target resources required by each target cloud desktop are determined based on the target resources required by all target 3D programs running on the target cloud desktop; and based on the overall target resources, a corresponding number of graphics card resources are allocated from the graphics card resource pool to the rendering main process corresponding to the target cloud desktop, so that cloud desktops that require more computing power can obtain more resource support, while cloud desktops with less demand are allocated fewer resources; avoiding the situation where a single cloud desktop occupies the entire graphics card, not only realizes the dynamic allocation of graphics card resources according to the actual example requirements of each target cloud desktop, but also effectively avoids the waste of computing power, and can also cope with peak demand.

[0064] Step S130: Control the target rendering main process to generate rendering instructions based on the rendering configuration file, and control the target rendering main process to execute the rendering instructions based on the divided graphics card resources.

[0065] In an embodiment of the present application, after controlling the target rendering main process to generate rendering instructions based on the rendering configuration file, it is necessary to determine the rendering sub-process corresponding to the target 3D program as the target rendering sub-process according to the identifier of the target 3D program.

[0066] In an embodiment of the present application, controlling the target rendering main process to execute rendering instructions based on the divided graphics card resources includes: controlling the target rendering main process to send the generated rendering instructions and the divided graphics card resources to the target rendering sub-process; controlling the target rendering sub-process to execute rendering instructions based on the graphics card resources.

[0067] In the embodiment of the present application, each target 3D program corresponds to a rendering sub-process, thereby isolating the rendering tasks of different 3D programs and preventing the rendering anomaly of a single 3D program from affecting the normal execution of the rendering tasks of other 3D programs.

[0068] In an embodiment of the present application, the target rendering main process is used to generate corresponding rendering instructions based on the identifier of the target 3D program sent by the server and the rendering configuration file of the target 3D program, and send them to the target rendering sub-process corresponding to the target 3D program, and the target rendering sub-process completes the rendering task.

[0069] In an embodiment of the present application, if the rendering task of the target rendering sub-process becomes more complex, the target rendering sub-process generates a rendering resource request and sends it to the server using the target rendering main process; the server divides the corresponding graphics card resources from the graphics card resource pool according to the target resources required in the rendering resource request and forwards them to the target rendering sub-process that sends the rendering resource request through the corresponding target rendering main process, thereby avoiding performance bottlenecks.

[0070] Step S140, obtaining a rendering result obtained by executing a rendering instruction by a target rendering main process; and sending the rendering result to a target cloud desktop corresponding to the target rendering main process for display.

[0071] In an embodiment of the present application, after the target rendering sub-process executes the corresponding rendering instruction and obtains the rendering result, the identifier of the target 3D program in the rendering request corresponding to the rendering result and the rendering result will be sent to the server through the target rendering main process, and the server will then send it to the target cloud desktop corresponding to the target rendering main process through the serial port and shared memory.

[0072] In an embodiment of the present application, after the target cloud desktop receives the identifier of the target 3D program and the rendering result in the rendering request corresponding to the corresponding rendering result, the rendering proxy component sends the rendering result to the corresponding target 3D program according to the identifier of the target 3D program, so that the target 3D program displays the rendering result.

[0073] In the embodiment of the present application, the cloud desktop is equivalent to a virtual machine, which is equipped with a virtual graphics card (a graphics card device simulated by KMD). The virtual graphics card is used to receive instructions issued by the target 3D program and display the rendering results on a real device.

[0074] In an embodiment of the present application, whether it is a rendering request sent by the target cloud desktop to the server, or a rendering result and a corresponding 3D program identifier sent by the server to the target cloud desktop, they are transmitted simultaneously through the serial port and shared memory; specifically, the seial serial port socket is used as a signaling channel (which can transmit rendering requests, etc.), and the ivshmem shared memory is used as a transmission channel for big data (which can transmit rendering results or rendering configuration files), which are integrated into the communication method between the virtual machine and the Linux project, ensuring efficient communication.

[0075] Corresponding to the above method, the embodiment of the present application also provides a rendering device for a cloud desktop, such as Figure 2 As shown, the rendering device of the cloud desktop includes:

[0076] The receiving unit 210 is used to receive a rendering request sent by a target cloud desktop connected to the server when running a target 3D program; wherein the server sets a rendering main process for the target cloud desktop; the rendering request includes a rendering configuration file of the target 3D program and target resources required for rendering the target 3D program;
