Embodiment Construction

[0024] A method for implementing skeletal animation, comprising:

[0025] (a) Create a virtual bone node based on the LOD value of the current required animation, and each node is bound to the original bone of the bone animation;

[0026] (b) Under the coordinate system of the virtual skeleton, the keyframe data of the original skeleton is transformed into a coordinate system, that is, the original skeleton keyframe data is converted into the keyframe data of the virtual skeleton;

[0027] (c) By unifying the bone data of key frames, the reuse of bone animations of different bones is realized;

[0028] Between the step (a) and the step (b), it further includes: converting the association between the skeletal node data bound to the virtual node and its grid data into the association between the virtual node and the grid data.

[0029] Before described step (a), also include according to the conversion quality of current skeletal animation, namely LOD value, confirm the number ...

Abstract

The invention relates to the technical field of computer graphics, in particular to a skeletal animation implementation method. The skeletal animation implementation method is based on the secondary extraction of skeletal animation of virtual skeletons, is used for unifying the skeletal animation of different skeletons to realize the purpose of reuse, and reuses the skeletal animation to the most extent by partitioning virtual points according to kinematics logic. Most of the reuse adopts the storage mode of virtual skeletons; and by constructing a set of standard virtual skeletons, the skeletal animation data link and reuse of different skeletons are realized. The reuse ratio of skeletal animation is increased, and the memory space required by the skeletal animation is reduced.

Description

technical field [0001] The invention relates to the technical field of computer graphics, and more specifically, to a method for realizing skeletal animation. Background technique [0002] Character animation is an important part of computer animation technology, and has been playing an important role in computer-aided animation film production and various advertisement production. [0003] With the improvement of computer hardware capabilities and the improvement of rendering technology, the images drawn by computers are becoming more and more realistic. Not only has there been further development in traditional animation, but 3D animation movies have also become more and more popular with audiences. [0004] In skeletal animation, an animated character is represented by two parts: one part is a series of bones that form a hierarchy, that is, the skeleton (skeleton), each bone data contains its own animation data; the other part is the skeleton The skin (skin), that is, th...
