Struct LocalAxis 

pub struct LocalAxis {
    pub x: Vec3A,
    pub z: Vec3A,
}

PMX bone local-axis descriptor (bone-local X/Z directions from the file).

The runtime builds a defensive right-handed orthonormal frame from these vectors for IK angle-limit evaluation only. Ordinary pose evaluation does not reorient bones by this frame.

Fields

x: Vec3A

z: Vec3A

Implementations

impl LocalAxis

pub fn new(x: Vec3A, z: Vec3A) -> Self

pub fn basis_quat(self) -> Option<Quat>

Build a right-handed orthonormal basis quaternion whose columns are (x, y, z) in bone-local space: y = normalize(z × x), z = x × y.

Returns None when inputs are non-finite or degenerate (near-zero / nearly parallel axes). Callers must treat None as “no local axis”.
