### 技术细节
|
||
Features:
|
||
- Import mo-cap animation in BVH format and provide a preview.
|
||
- Retarget mo-cap animation to skeletal mesh asset.
|
||
- Supports more precise restoration of the position of end joints using IK.
|
||
- Supports synchronizing animation to root and IK bones.
|
||
- Supports baking vertical or (and) horizontal root displacements into animations.
|
||
- Support for selectively preserving root rotation.
|
||
- Support for converting animations with root motion to in-place animations.

# 项目需求
|
||
1. 研究UE5的骨骼链&IK 动画重定向算法。
|
||
2. 研究Swift Motion Toolkit的动画重定向算法。
|
||
3. 比较两者算法优劣；并从Runtime的角度提出改进思路。
|
||
4. 搜索相关动画重定向论文，编写算法解析文档。
|
||
## 重定向过程简述（输入&输出）
|
||
1. 提供SourceSkeleton、TargetSkeleton2个骨骼FBX文件，以及若干SourceAnimation动画数据(基于SourceSkeleton)FBX文件。
|
||
2. 通过计算SourceSkeleton、TargetSkeleton差异，将SourceAnimation动画数据转换成TargetSkeleton版本的动画数据。
|
||
3. 输出成FBX文件。
