Abstract

The invention discloses a 3 dimensional bone animation compression method and apparatus. The method includes the following steps: determining whether the bone key frame data of all frames corresponding to each bone node all completely the same; if the bone key frame data are completely the same, saving the bone key frame data of a first frame of the current bone node in a first fixed-point number storage data file format which corresponds to a certain first compression type, and if the bone key frame data are not completely the same, saving the bone key frame data of the first frame and the bone key frame data of the other key frames that differ from the bone key frame data of the first frame, acquiring a required number of the compressed bone key frame data, generating compression files that conform with the required number, saving the bone key frame data of the key bones at varying time, based on certain requirements, and deleting or decreasing the bone key frame data. The method saves storage space and has more flexible compression methods.

Description

technical field [0001] The present disclosure relates to the technical field of three-dimensional skeleton animation data processing, in particular to a method and device for compressing three-dimensional skeleton animation. Background technique [0002] With the development of science and technology, the game function of the terminal is no longer limited to changing the static position of things or changing the attributes of things, but has strong dynamic entertainment, mainly for key frame animations with strong interaction in terms of time and action For games, in order to highlight a more three-dimensional animation effect, there is a form of 3D graphic animation. The key frames that make up the 3D graphic animation include displacement key frames, rotation key frames, and zoom key frames. The data representation of the displacement key frames is A 3-dimensional vector, in the uncompressed state, the storage format of the 3-dimensional vector is 3 FIX16 data storage form...
