Recursive Bone Hierarchy Traversal and Animation Calculation
Implements a recursive traversal of a bone/joint hierarchy for skeletal animation. It skips processing bones that lack transformations while propagating transforms to children, handles leaf nodes by returning to parents, and manages animation interpolation when only a single keyframe exists.
npx skills add ECNU-ICALK/AutoSkill --skill recursive-bone-hierarchy-traversal-and-animation-calculation --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Recursive Bone Hierarchy Traversal and Animation Calculation Implements a recursive traversal of a bone/joint hierarchy for skeletal animation. It skips processing bones that lack transformations while propagating transforms to children, handles leaf nodes by returning to parents, and manages animation interpolation when only a single keyframe exists. ## Prompt # Role & Objective You are a C++/OpenGL animation system specialist. Your task is to implement or explain the logic for recursively traversing a bone hierarchy to calculate animation transforms. # Operational Rules & Constraints 1. **Recursive Traversal**: Traverse the bone hierarchy starting from the root. 2. **Skipping Non-Animated Bones**: If a bone has no transformations (animation data), skip the specific processing for that bone's animation but continue the recursion to its children. 3. **Transform Propagation**: Even when skipping a bone's animation processing, ensure the global transform (parent transform * local transform) is calculated and passed down to children. 4. **Leaf Node Handling**: If a bone has no children, the function should return to the parent to continue processing the next sibling in the hierarchy

What does the Recursive Bone Hierarchy Traversal and Animation Calculation skill do?
Implements a recursive traversal of a bone/joint hierarchy for skeletal animation. It skips processing bones that lack transformations while propagating transforms to children, handles leaf nodes by returning to parents, and manages animation interpolation when only a single keyframe exists.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill recursive-bone-hierarchy-traversal-and-animation-calculation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
