Struct Joint 

pub struct Joint {
    pub name: String,
    pub parent: Option<usize>,
    pub inverse_bind_matrix: Mat4,
    pub local_bind_transform: Transform,
}

One joint’s static rig data — everything that never changes once the skeleton is built, as opposed to Transform, which is per-pose (a new one every frame, from AnimationClip::sample).

Fields

name: String

For lookup via Skeleton::joint_index_by_name and diagnostics — has no effect on the math.

parent: Option<usize>

Index into the same Skeleton’s joint list. None for a root joint (no parent within this skeleton).

inverse_bind_matrix: Mat4

Transforms a vertex from mesh-bind space into this joint’s local space — the fixed per-joint matrix Skeleton::skinning_matrices multiplies each joint’s current world matrix by.

local_bind_transform: Transform

This joint’s own local transform in the bind pose — the fallback AnimationClip::sample uses for any joint (or T/R/S component) a clip doesn’t animate.
