The invention belongs to the field of teaching application of information technology, and provides a 5G strong-interaction remote delivery teaching system based on a holographic terminal and a workingmethod thereof, the remote delivery teaching system comprises a data acquisition module, a data transmission module, a 5G cloud rendering module, a natural interaction module, a holographic display module and a teaching service module, the method comprises the following steps: acquiring diversified teaching behaviors and holographic images of a teacher in a lecture classroom in real time by virtue of recording and broadcasting acquisition equipment and a sensor, through a 5G network link, realizing data transmission between the classroom end and the cloud server as well as between the classroom end and the rendering cluster, and pushing the rendered holographic images to a holographic display terminal at a classroom end after cloud decoding, scene matching, GPU real-time rendering, cloudcoding and other links are carried out on data such as audio and video streams, holographic images and the like. According to the invention, requirements of remote special delivery teaching can be met, and a new holographic presentation mode and an interactive form are provided for a special delivery class.

The invention relates to an iFrame embedded Web3d (Web three-dimensional) system based on cloud rendering. The iFrame embedded Web3D system comprises a file transmission module, a server rendering module, a display module, an interactive module, a sharing module and a file managing module, wherein the server rendering module comprises a model state acquiring unit, an organizing and distributing unit, a calculating unit and a result output unit. According to the system, various large or extra-large three-dimensional models can be directly and smoothly browsed, operated and controlled on webpages through browsers without installing any plugin; hardly any requirement is made on a display terminal, and various mobile intelligent terminals can be supported to view the models smoothly; the generation of iFrame codes can be supported, and models are embedded into various different platforms or websites; multiuser concurrent access can be supported; and since clients only can acquire rendered pictures instead of model data, so that the data security of users is well guaranteed.

The invention discloses a cloud computing based real-time off-screen rendering method, apparatus and system. The method comprises: receiving a cloud rendering service request sent by a client; enabling a rendering resource and creating a direct connection link of the client and the rendering resource, so that the rendering resource can directly process the cloud rendering service request; performing real-time rendering by the rendering resource and directly sending a rendering result generated in real time to the client; and enabling the client to receive the rendering result in real time and display a picture according to the rendering result. Numerous client devices that are online at the same time can be supported, massive rendering service requests of the client devices can be born, and all online rendering tasks are independent mutually, so that the communication load of a cloud end is reduced and the time delay of a cloud rendering service is shortened.

The invention provides a cloud rendering method. The method comprises: constructing a virtual server cluster at the cloud; and deploying a visual application to the virtual server cluster, performingrendering at a cloud end by adopting a virtualization technology, meanwhile, controlling rendering of a visual application by realizing a corresponding control flow instruction at the cloud end, coding a rendered image by realizing a corresponding image coding technology at the cloud end, and performing corresponding decoding at a client end, so that the image is visually displayed in the client end. The invention further provides a cloud rendering system. The beneficial effects of the system and the method are that the client does not need to carry out other complex operation, and can operatethe heavy-weight visual application on the client just through the decoding of the client according to the corresponding image decoding technology, thereby reducing the application conditions, and facilitating the popularization of the heavy-weight visual application.

The embodiment of the invention discloses an image rendering method. Server and terminal, The method and the device are used for avoiding the situation that the terminal processing hardware cannot meet the requirement by combining a cloud rendering function, further enabling the cloud to achieve the required rendering effect without too many system resources in the rendering process by collectingthe watching information, reducing the pressure on the wireless communication process, and saving the wireless communication resources. The method provided by the embodiment of the invention comprisesthe steps that a server receives fixation information sent by a terminal; The server renders the first scene according to the gaze information to obtain a second scene; And the server sends the second scene to the terminal.

The invention relates to the technical field of three-dimensional display cloud rendering, and discloses a three-dimensional display cloud rendering method and system, and the method comprises the steps of a three-dimensional display terminal registering a play request to a cloud rendering server, so as to play three-dimensional contents; acquiring parameter data of the three-dimensional display terminal according to the playing request; wherein the three-dimensional display terminal parameter information comprises manufacturer and serial number information of the three-dimensional display terminal; verifying the parameter data of the three-dimensional display terminal through a cloud rendering server, enabling the three-dimensional display terminal to be in contact with the cloud rendering server, and requiring the three-dimensional display terminal to provide the parameter data of the three-dimensional display terminal; acquiring image information generated by rendering according tothe verified three-dimensional display terminal parameter data; and pushing the image information generated by rendering to a three-dimensional display terminal for playing through communication connection. Data exchange between the three-dimensional display terminal and the cloud rendering server is realized, so that the cloud rendering server performs cloud rendering on the three-dimensional content according to the preset parameters.
