When a user has a rendering requirement, the three-dimensional model used for scene rendering does not need to be downloaded, and only a starting instruction needs to be generated through a user terminal and is sent to a remote cloud server through a mobile network (such as a 5G network) or other high-speed network channels through a browser and the like of the user terminal, so that access to the remote cloud server is realized.
That is to say, when a user needs to render and display a target three-dimensional scene model, a start instruction may be generated and sent to the cloud server through a user terminal held by the user, where the start instruction is used to instruct the cloud server to start a three-dimensional model rendering process.

It can be understood that after the start instruction is sent to the remote cloud server, the cloud server may start the three-dimensional model rendering process according to the start instruction, that is, wake up the Unity3D program. And then, the cloud server starts and runs a clustered three-dimensional rendering program to start clustered rendering of the target three-dimensional scene model. In the rendering process, the cloud server starts recording of a three-dimensional program rendering process picture to form a first video stream, and each frame of the first video stream forms a first rendering picture. And finally, the cloud server transmits the first rendering picture to the user terminal through a mobile network or other high-speed network channels in a video streaming mode.
When the first video stream sent by the cloud server is received, the first video stream can be played frame by frame in real time, that is, the first rendering picture is displayed on a screen of the user terminal. Optionally, the user terminal may also call and play the first video stream at a required time, so as to realize reproduction of the first rendered screen.
According to the three-dimensional scene model rendering and displaying method, the rendering program of the three-dimensional scene model is migrated to the cloud server, the transmission of the three-dimensional scene model data and the rendering result is realized through a mobile network or other network channels, and the cloud rendering and the localized displaying of the three-dimensional scene model can be realized, so that the characteristics of cloud computing virtualization, high expandability and low cost can be effectively utilized, the applicability is effectively improved, and the cost is reduced.
On the basis of the three-dimensional scene model rendering and displaying method provided by the above embodiments, the method further includes: in the process of playing the first video stream, receiving a first operation of a user on the first rendering picture, and sending an adjusting instruction to the cloud server based on the first operation, wherein the adjusting instruction is used for instructing the cloud server to adjust the rendering of the target three-dimensional scene model according to the first operation instruction; and receiving and playing a second video stream in real time to display a second rendered picture, wherein the second video stream is obtained by the cloud server performing local adjustment and event response on the clustered rendering result based on the adjustment instruction and performing re-recording on the rendered picture.
It can be understood that, in the process of displaying the initially rendered first rendered picture, an adjustment operation of the displayed picture by the user may also be accepted, and the adjustment operation may be referred to as a first operation.
After the first operation of the user is read, an adjustment target of the user, including an adjustment position, an adjustment mode and the like, can be determined according to the first operation. And then searching a preset instruction table according to the first operation, acquiring an adjusting instruction corresponding to the first operation, and sending the adjusting instruction to the cloud server through the network, so that the cloud server can adjust the rendering of the target three-dimensional scene model according to the position, the mode and the like of the first operation instruction. The instruction list comprises the corresponding relation between the user operation type and the adjusting instruction.
And then, the cloud server executes corresponding tasks such as rendering modification and adjustment, event response and the like according to the adjustment instruction. In the process of adjusting the rendering, the cloud server records a three-dimensional program rendering process picture in the same way to form a second video stream, and each frame of the second video stream forms a second rendering picture. And finally, the cloud server transmits the second rendering picture to the user terminal through a mobile network or other high-speed network channels in a video streaming mode.
When the second video stream sent by the cloud server is received, the second video stream can be played frame by frame in real time, that is, the second rendering picture obtained after rendering adjustment is displayed on the screen of the user terminal. Optionally, the user terminal may also call and play the second video stream at a required time, so as to realize reproduction of the second rendered screen.
According to the invention, the user can flexibly adjust the rendering result according to the requirement by receiving the operation of the user and sending the adjusting instruction to the server according to the user operation, so that the personalized requirement of the user can be met.
Optionally, the method for rendering and displaying a three-dimensional scene model according to the foregoing embodiments, where sending an adjustment instruction to the cloud server based on the first operation includes: searching and acquiring the adjusting instruction in a preset instruction set based on the first operation, the action position of the first operation in the first rendering picture and the current state of the first rendering picture, and sending the adjusting instruction to the cloud server through a network.
It can be understood that the adjustment instruction corresponding to the operation of the user such as interactive click can be obtained from the user terminal calculating the interactive click position and the selected instruction set and sent to the remote server. For example, a user clicks a picture rendered on a screen (i.e., the user inputs a first operation), the local user terminal collects screen coordinates of the picture clicked by the user, searches a corresponding adjustment instruction in a set instruction set according to the coordinate position and the current program state, and sends the adjustment instruction to the remote server in a network manner.
