Cloud game picture rendering method and device

Abstract

The embodiment of the invention discloses a cloud game picture rendering method, which comprises the following steps: generating a corresponding game rendering instruction according to graphic API calling information sent by a game client; based on a preset hash function, obtaining a hash value of the game rendering instruction; determining whether the game rendering instruction is a high-frequency calling instruction or not according to the hash value; wherein the high-frequency calling instruction is a game rendering instruction of which the calling frequency reaches a first preset threshold value; and under the condition that the game rendering instruction is a high-frequency calling instruction, obtaining an index value of the game rendering instruction, and sending the index value to the game client, so that the game client searches and executes the game rendering instruction in a memory according to the index value, and renders the current frame of game picture. The method is used for solving the problems that the cloud game picture rendering calculation amount is large, the bandwidth requirement is high, and game delay is increased.

Description

Technical field [0001] The present application relates to the field of game screen processing technology, in particular to a cloud game screen rendering method and apparatus. Background [0002] Cloud games are cloud-based games, in the cloud game mode of operation, all games are running on the server side, and the rendered game screen is compressed and transmitted to the user through the network. On the client side, the user's gaming device does not require any high-end processor and graphics card, only basic video decompression capabilities. In a cloud game, when a user requests to run a game, the server starts the game instance, executes the game logic, responds to user input, renders the game screen at the same time, and finally compresses the rendered game screen and transmits it to the client as a video stream. [0003] However, this kind of cloud game built on video streaming has high latency and greater bandwidth requirements, which greatly affects the user experience. M...

AI Technical Summary

Problems solved by technology

[0003] However, this kind of cloud game based on video streaming has high latency and a large demand for bandwidth, which greatly affects user experience.

Moreover, cloud gaming is an application with heavy computing and rendering tasks, so it requires high logical computing and rendering capabilities of the cloud server CPU, resulting in high deployment costs of cloud servers and weak game concurrency

[0004] Through the edge computing technology, the logical calculation and rendering can be implemented in the client. The client and the server will perform an interactive cycle to render the game screen frame, but the correct execution of the graphics rendering command needs to contain the correct command parameters, Vertex and index data, texture data, etc. These data volumes are huge, and transferring these data will consume a lot of network bandwidth

And due to the scene similarity between adjacent frames of the game and the user sometimes being in an on-hook state, performing a complete rendering process for each frame of the game and achieving the same rendering effect will cause unnecessary calculations and data transmission The amount increases the delay of game screen rendering, causing bad game experience to users
