Title:
ANIMATION BLEND SPACE PARTITIONING METHOD AND APPARATUS, AND DEVICE AND READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/258544
Kind Code:
A1
Abstract:
An animation blend space partitioning method and apparatus, and a device and a readable medium. The method comprises: obtaining an animation set, the animation set comprising multiple sample skeletal animations to be subjected to animation blending (101); performing motion analysis on a target object in each sample skeletal animation to obtain multiple types of motion parameters corresponding to the target object in each sample skeletal animation (102); constructing an animation blend space by using the multiple types of the motion parameters as dimensions (103); and determining first reference points corresponding to the motion parameters in the animation blend space, and partitioning the animation blend space on the basis of the first reference points (104). By means of the present method, motion analysis is performed on the target object in each sample skeletal animation; the motion parameters obtained by motion analysis are more accurate; and the animation quality of the skeletal animation obtained by animation blending processing on the basis of the motion parameters is high.
