In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
In the existing graphics display mode, aiming at directly allocating physical three-dimensional hardware to a virtual machine for use, a rendering mode through the virtual machine needs support of special hardware, and is not suitable for all three-dimensional graphics display scenes. Aiming at the mode of sending the graphic rendering instruction and the three-dimensional graphics to the client through the network for rendering, when the data volume of the graphic rendering instruction and the three-dimensional graphics is large, the transmission rate of the network is influenced, and the display efficiency of the graphics is influenced. Based on this, embodiments of the present application provide a method, an apparatus, a system, an electronic device, and a storage medium for displaying a graphic, which are described below by way of embodiments.
To facilitate understanding of the present embodiment, a detailed description will be given of a graphic display method disclosed in the embodiments of the present application. The first graphic display method shown in fig. 1 includes the following steps:
s101: receiving a graph viewing request sent by a client connected with a target virtual machine; the graph viewing request carries a target three-dimensional graph; the target virtual machine is used for determining a graph rendering instruction according to the graph viewing request;
s102: forwarding the graphic rendering instruction to a display card of the server by utilizing a redirection technology so that the display card renders the target three-dimensional graphic according to the graphic rendering instruction;
s103: and sending the target three-dimensional graph rendered by the display card to the client so that the client displays the target three-dimensional graph.
By the graphic display method, the graphic rendering instruction determined by the target virtual machine can be redirected to the display card of the server, so that the target three-dimensional graphic is directly rendered on the display card, a phenomenon of network delay caused by sending a large number of graphic rendering instructions and the target three-dimensional graphic to the client side is avoided to a certain extent, the rendering efficiency of the three-dimensional graphic is improved, and the display efficiency of the target three-dimensional graphic is further improved.
In step S101, the virtual machine refers to a virtual desktop operating system, and may specifically be a cloud desktop operating system. When the client is connected with the virtual machine, the virtual machine can provide a virtual operating environment for the client, and the system operated by the user can be a remote desktop operating system.
When a user opens a virtual machine login interface of a client, the login interface can display a virtual machine account list, and a plurality of virtual machines can be arranged under the virtual machine account list. The target virtual machine may refer to the virtual machine to which the user has selected to connect.
In the embodiment of the present application, the client may be connected to the target virtual machine using any feasible communication protocol, and the system running by the target virtual machine may be any feasible system (for example, Linux operating system, Windows7 operating system, Windows10 operating system, etc.). Here, the client may connect the target Virtual machine using a VNC (Virtual Network Computing) communication protocol, for example.
After a user performs a viewing operation for a target three-dimensional graph in an application program operated by a client, the client can send a graph viewing request carrying the target three-dimensional graph to a server, and a target virtual machine in the server can determine a graph rendering instruction corresponding to the target three-dimensional graph according to the graph viewing request.
Specifically, OpenGL (Open Graphics Library) may be run in the target virtual machine, and the user may perform a viewing operation on a target three-dimensional graph in OpenGL, where the graph rendering instruction is an OpenGL instruction.
In general, a virtual machine may have corresponding hardware, but the hardware of the virtual machine is general-purpose hardware which is virtually simulated, and only the most basic simulation is performed on a graphics card, that is, the hardware is simulated, rather than physical hardware. Therefore, under the virtual operating environment of the virtual machine, the rendering of the target three-dimensional graphics cannot be realized. In order to realize the rendering of the target three-dimensional graph, the virtual machine sends the graph rendering instruction and the corresponding target three-dimensional graph to the client according to the graph viewing request, so that the physical display card of the client renders the target three-dimensional graph, and when the data volume forwarded to the client is large, the network transmission efficiency may be influenced.
In the present application, in order to prevent the target virtual machine from sending the graphics rendering instruction to the client, step S101 is performed, and step S102 is performed.
In step S102, the system of the server is a Linux operating system, and the graphics card of the server is a physical graphics card, where the graphics rendering instruction may be redirected and forwarded to the graphics card of the server by using a redirection technology.
In one possible implementation, the 3D acceleration controller may be used to redirect the graphics rendering instructions to a graphics card of the server, so that the graphics card renders the target three-dimensional graphics according to the graphics rendering instructions.
For example, for a Linux hosting server, the 3D acceleration controller redirects graphics rendering instructions to the graphics card of the server using a redirection technique Linux OpenGL Hook.
In a possible implementation, when step S102 is executed, the following steps may be executed:
s1021: storing the target three-dimensional graph in a pixel buffer area established in advance;
s1022: and redirecting the graphic rendering instruction to a display card of the server by using the 3D control accelerator so that the display card renders the target three-dimensional graphics stored in the pixel buffer area according to the graphic rendering instruction.
In an implementation of S1021-S1022, the 3D control accelerator may pre-establish an invisible pixel buffer area when running the application program, and the target three-dimensional graphic is stored in the pre-established pixel buffer area.
After the 3D control accelerator redirects the graphic rendering instruction to the display card of the server, the pixel buffer area can quickly transmit the target three-dimensional graphic to the display card, so that the display card renders the target three-dimensional graphic stored in the pixel buffer area according to the graphic rendering instruction, and the rendering efficiency of the target three-dimensional graphic is improved.
In a possible implementation manner, before receiving a graphics viewing request carrying a target three-dimensional graphics sent by a client connected to a target virtual machine, the method further includes:
s201: receiving a virtual machine starting request sent by a client; the virtual machine starting request carries identity information of a target virtual machine;
s202: and starting the target virtual machine by using the 3D acceleration controller according to the identity information of the target virtual machine.
In step S201, here, the identity information of the target virtual machine may be account information. After the user selects the target virtual machine, the user can execute click operation on the target virtual machine, the client can send a virtual machine starting request to the remote desktop controller in the server, the remote desktop controller can start remote control, and the 3D acceleration controller is informed to enter a target virtual machine starting process.
In step S202, in the started VNC session (i.e., vnssesion 1), the 3D acceleration controller starts the target virtual machine using the component VirtualGL.
When step S103 is executed, the display card of the server renders all the target three-dimensional graphics, and then sends the rendered target three-dimensional graphics to the client.
Generally, the target three-dimensional graphics received by the client are all in mjpeg (motion Joint Photographic Experts group) format, and the target three-dimensional graphics can be directly displayed on the client after being decoded by software or hardware.
In one possible implementation, the VNC communication protocol may be utilized to send the target three-dimensional graphics rendered by the graphics card to the client.
In a possible implementation manner, the graphics card may forward the rendered target three-dimensional graphics to the 3D acceleration controller, and the 3D acceleration controller sends the target three-dimensional graphics to the client.
The following takes a server using a VNC communication protocol and a Linux system as an example, and specifically introduces a graph display method provided in the embodiment of the present application, such as a flowchart of a second graph display method shown in fig. 2.
Step 1: the client sends a request for starting a target virtual machine to a remote desktop controller in the server;
the virtual machine refers to a virtual desktop operating system running on a server, and specifically may be a cloud desktop operating system. When the client is connected with the virtual machine, the virtual machine running on the server can provide a virtual operating environment for the client, so that a user operates a remote desktop operating system.
When a user opens a virtual machine login interface of a client, the login interface can display a virtual machine account list, and a plurality of virtual machines can be arranged under the virtual machine account list. The target virtual machine may refer to the virtual machine to which the user has selected to connect.
After the user selects the target Virtual machine, the client sends a request for starting the target Virtual machine to a remote desktop controller in the server through a VNC (Virtual Network Computing) communication protocol.
Step 2: the remote desktop controller starts remote control on the server and informs a 3D acceleration controller in the server to start a target virtual machine;
here, the remote control is vnserver, the graphical interface server inside the server shows that the interface x server display defaults to D0 (environment with 3D graphics card drive), and the session of the VNC started here (vnsession 1) assumes that the x server display is D1. Here D0 and D1 are numbers of the graphical interface server presentation interface x server display. In different sessions, the Linux system has an independent x server, and the display code represents different x servers.
And step 3: starting a target virtual machine by the 3D acceleration controller;
in the session (vnsession 1), the 3D acceleration controller starts the virtual machine using the component VirtualGL.
And 4, step 4: a client sends a graph checking request carrying a target three-dimensional graph to a server;
the target virtual machine may run OpenGL (Open Graphics Library), and after a user performs a viewing operation for a target three-dimensional graph in the OpenGL, the client sends a graph viewing request carrying the target three-dimensional graph to the server.
And 5: a target virtual machine in the server determines a graphic rendering instruction corresponding to a target three-dimensional graphic according to the graphic viewing request;
the graphics rendering instruction is an OpenGL instruction.
And the target virtual machine sends the OpenGL instruction and the corresponding target three-dimensional graph to the client according to the graph viewing request so that the physical display card of the client renders the target three-dimensional graph. To prevent the target virtual machine from sending graphics rendering instructions to the client, step 6 is therefore performed.
Step 6: intercepting a graphics rendering instruction in a target virtual machine by a 3D acceleration controller;
and 7: the 3D acceleration controller forwards the intercepted graphics rendering instruction to a display card of the server;
the 3D acceleration controller may redirect the OpenGL instruction to the graphics card of the server using a redirection technology Linux OpenGL Hook, and forward the OpenGL instruction to the graphics card of the server.
And 8: the display card renders the target three-dimensional graph according to the graph rendering instruction;
when running an application, the 3D control accelerator may pre-establish an invisible pixel buffer where the target three-dimensional graphic is stored.
After the 3D control accelerator redirects the graphic rendering instruction to the display card of the server, the pixel buffer area can quickly transmit the target three-dimensional graphic to the display card, so that the display card renders the target three-dimensional graphic stored in the pixel buffer area according to the graphic rendering instruction, and the rendering efficiency of the target three-dimensional graphic is improved.
And step 9: the display card outputs the rendered target three-dimensional graph to a remote desktop controller;
step 10: the remote desktop controller sends the rendered target three-dimensional graph to the client;
step 11: and the client displays the target three-dimensional graph and continues to execute the step 4.
The target three-dimensional graphics received by the client are all in a MJPEG (motion Joint Photographic Experts group) format, and the target three-dimensional graphics can be directly displayed on the client after being decoded by software or hardware.
