[0068] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0069] The terms "first", "second", "third" and "fourth" (if any) in the description and claims of this disclosure and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0070] Figure 1 This is a process of an image rendering method provided by an embodiment of the present disclosure Figure 1 , this method is applied to the client. Figure 1 As shown, the image rendering method includes the following steps:

[0071] S101: Receive an image rendering instruction sent by a server, where the image rendering instruction includes identification information of an application corresponding to an image to be rendered and a first handle value of a first window.

[0072] A handle is a special type of smart pointer. A handle value is a unique integer value, a 4-byte (8-byte in 64-bit programs) value, used to identify different objects and instances of the same type in an application, such as a window, button, icon, scroll bar, output device, control, or file. For example, the application may be an online game or 3D video, but this embodiment does not impose any specific limitations.

[0073] In this step, the first handle value of the first window is generated by the server after receiving the rendering request sent by the client. After generating the first handle value, the server sends a create window instruction to the client, and the create window instruction includes the first handle value. The following describes how the server generates the first handle value:

[0074] The client sends a rendering request to the server, the rendering request including identification information of the application. After receiving the rendering request, the server responds to the rendering request and generates a first handle value and a first context value for the first window. After generating the first handle value and the first context value, the server sends a create window instruction to the client, the create window instruction including the first handle value and the identification information.

[0075] Exemplarily, the server can also send the first context value to the client. After the client receives the create window instruction and the first context value sent by the server, it executes the create window instruction, generates a second handle value and a second context value for the second window for rendering the image to be rendered, and then establishes a first correspondence between the first handle value and the second handle value and a second correspondence between the first context value and the second context value.

[0076] After the first corresponding relationship is established, the client can then determine the second handle value corresponding to the first handle value according to the first corresponding relationship.

[0077] After establishing the second corresponding relationship, the client can then determine the second context value corresponding to the first context value according to the first context value.

[0078] S102: Determine a second handle value corresponding to the first handle value according to the first corresponding relationship, where the second handle value is a handle value of the second window;

[0079] S103: Render the image to be rendered in the second window according to the second handle value.

[0080] The client receives an image rendering instruction sent by the server, including the identification information of the application and the first handle value. After receiving the image rendering instruction, the client determines the second handle value corresponding to the first handle value based on the first correspondence, and renders the image to be rendered in the second window based on the second handle value and the second correspondence.

[0081] In this embodiment, the image to be rendered can be rendered in the second window based on the second handle value and the second context value. If the image to be rendered fails to be rendered in the second window, the first context value corresponding to the second context value is determined based on the second correspondence. The first context value and the second context value are then compared to determine the cause of the image rendering failure, so that a rendering failure prompt message can be sent to the user. The context value is the environment in which the application runs, including the application's program state and variable status.

[0082] Exemplarily, before the client renders the image to be rendered in the second window according to the image rendering instruction, the client needs to generate the second window. How to generate the second window is described below.

[0083] The client receives a window drawing instruction sent by the server, where the window drawing instruction includes the identification information and the first context value; determines the first context value and the second context value corresponding to the first context value according to the second corresponding relationship; and executes the window drawing instruction in the second context value to generate the second window.

[0084] It should be noted that the window is a two-dimensional image, and the window drawing instruction is a two-dimensional image rendering instruction. By executing the window drawing instruction in the second context value to generate the second window, the rendering of the two-dimensional image window can be completed. Furthermore, after the second window is generated, the image to be rendered is rendered in the second window based on the second handle value and the second context value. When the image to be rendered is a three-dimensional image, the solution of the embodiment of the present disclosure can achieve the fusion of three-dimensional image rendering and two-dimensional image rendering.

[0085] The image rendering method provided by the embodiment of the present disclosure is capable of receiving an image rendering instruction sent by a server, the image rendering instruction including identification information of an application corresponding to an image to be rendered and a first handle value of a first window; determining a second handle value corresponding to the first handle value based on the first corresponding relationship, the second handle value being the handle value of a second window; rendering the image to be rendered in the second window based on the second handle value, and rendering the image to be rendered on the client, thereby avoiding the problems of network congestion and large server computing load caused by a very large amount of transmitted image data when transmitting 3D images using existing technologies, thereby improving image rendering efficiency and reducing the server computing load.

[0086] The following combination Figure 2 and Figure 3 , the image rendering method provided by the embodiment of the present disclosure is further described in detail. Figure 2 This is a process of an image rendering method provided by an embodiment of the present disclosure Figure 2 ,like Figure 2 As shown, the method includes the following steps:

[0087] S201: When a server receives a 3D rendering request from a client, the server obtains 3D rendering-related instructions from a Windows Display Driver Model (WDDM), locally executes a Create Window instruction in the 3D rendering-related instructions, and records a first handle value generated after executing the Create Window instruction.

[0088] S202: The server sends the obtained Create Window instruction and the first handle value to the client.

[0089] S203. After receiving the Create Window instruction sent by the server, the client executes the Create Window instruction and records the second handle value generated after executing the Create Window instruction.

[0090] S204: The client generates a mapping table between the second handle value and the first handle value;

[0091] S205. When the client receives the 3D rendering instruction, it searches for the corresponding second handle value according to the first handle value received at the same time.

[0092] S206: The client finds a corresponding window locally according to the second handle value, and performs 3D image rendering in the window.

[0093] The above scheme is described in detail below.

[0094] First, when a 3D application running on a server renders its image, it can be decomposed into two parts: one is the rendering of the window part (rendering of 2D images, including forms, menus, navigation bars, etc.), and the other is the rendering of 3D images.

[0095] Window rendering (including forms, menus, navigation bars, etc.) is implemented using Graphics Device Interface (GDI) functions in Windows, while 3D image rendering is handled by the graphics card via the D3D Runtime. Breaking down application image rendering into two types of rendering instructions.

[0096] Then, the 2D rendering instructions (i.e. Figure 1 Window drawing instructions in the embodiment) and 3D rendering instructions (ie Figure 1 The most important instruction here is CreateWindow, which will return the window handle that needs to be bound for the execution of future 3D instructions. This is the key to combining 2D windows and 3D image rendering operations.

[0097] Then, the server sends the 2D rendering instruction and the 3D rendering instruction (with the first handle value) to the client.

[0098] The first instruction received by the client is the Create Window instruction, which carries the first handle value and the first context value returned when executed on the server. The client also executes this instruction, generates the client window and the corresponding second handle value and obtains the second context value of the client device, and then maps the second handle value of the client window to the first handle value sent by the server (i.e. Figure 1 The first corresponding relationship is established in the embodiment), and the first context value of the server and the second context value of the client are mapped one to one (ie Figure 1 (Establishing the second corresponding relationship in the embodiment).

[0099] After the client receives a 2D rendering instruction, it searches for the corresponding second context value of the client through the first context value carried by the instruction, and then executes the 2D rendering instruction in this context to realize the drawing of the window. The context is a Windows data structure that contains the drawing properties of a device. The drawing call after the client receives the 2D rendering instruction needs to use the context value. The context value specifically encapsulates a calling interface API for Windows applications used to draw lines, shapes, text, etc. In simple terms, the context is equivalent to the canvas in the drawing process. The context determines the properties of the canvas and encapsulates the methods of drawing on the canvas, such as drawing lines, drawing points, etc. In order to draw, you need to find this canvas, and obtaining the device context value can find this canvas. Figure 3 This is a schematic diagram of an image rendering process provided by an embodiment of the present disclosure. Figure 3 In the lower left window, the 3D rendering instruction has not been executed yet, so the area in the window where 3D rendering should be performed is blank.

[0100] After receiving a 3D rendering command, the client first determines the window to which the command belongs. This is done by searching the previously saved window handle mapping table using the first handle value (server-side) carried in the command to find the second handle value of the corresponding client window. The 3D rendering command is then executed on the window corresponding to this second handle value. This allows rendering to be performed in that window, which becomes the 3D rendering area. This completes the redrawing and fusion of all 2D rendering commands and 3D rendering commands for the entire application.

[0101] This method can fully realize the remote rendering of applications running on the entire server desktop operating system.

[0102] Based on the above Figure 1 The image rendering method described in the corresponding embodiment is as follows: an embodiment of the device disclosed herein, which can be used to execute the embodiment of the method disclosed herein.
