Abstract

The invention relates to the technical field of computers, and in particular to an animation data compressing and decompressing method and a device. Animation data is acquired by a server; and the animation data undergoes compressing processing as follows: implementing geometric transformation on skeleton transformation matrix data in skeleton animation data of each frame, so that the skeleton transformation matrix data is converted into corresponding vector components; transmitting the compressed animation data to a client side, correspondingly decompressing the compressed animation data by the client side and displaying animation, so that the skeleton animation data in each frame of the animation data undergoes special compressing processing; therefore, the quantity of the skeleton animation data can be effectively reduced, and subsequently, a compressing rate of the animation data can be improved and network transmission flow can be reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for compressing and decompressing animation data. Background technique [0002] Cloud gaming is a game method based on cloud computing. The game responds quickly and improves the user experience. However, when running a cloud game, a large amount of game animation data needs to be transmitted, the bandwidth requirement is higher, and the transmitted network traffic is relatively high. Therefore, the animation data needs to be compressed. [0003] In the prior art, the animation data compression method of cloud games is to use the difference between frames (Difference, Diff) compression algorithm, and use the data difference between frames of the animation data to perform inter-frame compression, and only save the data relative to the previous frame. The difference part of the frame, which compresses the raw data of the frames adjacent to the keyframe. [0...
