Method for optimizing skeletal animation reusing and memory usage

Abstract

The invention relates to a skeletal animation reusing method, in particular to a method for optimizing the skeletal animation reusing and the memory usage, and belongs to the field of computer graphics. The mode of carrying out logic blocking on animation data is adopted to carry out recombination on motion data of different skeletons and novel skeletal animations which completely do not need to be fused and calculated are output; the newly formed animations occupy a small memory and most of the novel skeletal animations consist of the existing small logic animation units; meanwhile, the novel skeletal animations are beneficial to the reduction of the workload of a graphic designer; and a great amount of novel skeletal animations are the reused skeletal animations, so that the animation loading speed is provided.

Description

Technical field [0001] The invention relates to a method for skeletal animation reuse, in particular to a method for optimizing skeletal animation reuse and memory occupation, and belongs to the field of computer graphics. Background technique [0002] The current character animation is usually realized by means of key frame animation or skeletal animation. Key frame animation, by preparing a set of time-related values ​​for the attributes that require animation effects (these values ​​are extracted from the more critical frames in the animation sequence), and the values ​​in other time frames can use these key values, using linear The interpolation method is calculated to achieve a relatively smooth animation effect. In ordinary 3D character animation, key frame animation uses key frames to generate animation for the character's Mesh model. However, since the key frame animation must store the positions of all vertices for each key frame, a larger storage space is required. F...

AI Technical Summary

Problems solved by technology

[0004] Skeletal animation itself also has its shortcomings, which are mainly reflected in the low reusability of animation

The animation reuse rate is low because the exact same animation rarely exists

Although the problem can be solved through animation fusion, animation fusion needs to play multiple animations at the same time, which means that additional calculations are required, and the increase in frame rate is not used.
