System and method for delivering graphics over network

Abstract

The present invention discloses a method and a system for delivering graphics from a server to a client device over a network. An application running on the server generates a virtual 3D environment containing a plurality of 3D models. The server checks the status of each 3D models in a predetermined order, and then, only those 3D models which are not pre-stored in the client device will all be rendered and encoded by the server into a frame of 2D video stream. The server then sends to the client device the frame and meta data of the 3D models which are pre-stored in the client device via the network. The client device uses the frame as a background for rendering the 3D models which are pre-stored in the client device but not included within the frame, so as to generate a mixed frame for output.

Description

technical field [0001] The present invention relates to a system and method for transmitting media such as images and sounds through a network, and in particular to a method for rendering 3D objects and sounds on a user device. The method is completed by combining the results of the following two: (a) Rendering of 3D objects and 3D sound by itself, and (b) 2D video with stereo sound provided by the server. Background technique [0002] In the past few years, online games have become a global trend. With the development of cloud computing related systems and technologies, a technology that uses servers to stream game content and provide services has also come out. [0003] A traditional method of providing cloud game services uses a server to be responsible for almost all calculations, that is, when cloud game services are to be provided, the server needs to generate a virtual 3D environment including a plurality of 3D objects that can be moved or controlled by participants ...

Problems solved by technology

However, the aforementioned traditional technique of performing rendering calculations for many players on the same server will lead to an excessive load on the server performing 3D rendering calculations; in addition, because the images seen by players are all transmitted in the form of destructively compressed 2D video streams Therefore, the quality of video and sound is not as good as that of the original 3D objects displayed, and the large amount of network communication bandwidth between the server and player devices has also become a major problem.
