Struct LinearTransformMeasurements 

#[non_exhaustive]
pub struct LinearTransformMeasurements {
    pub classification: LinearTransformClassification,
    pub axis_lengths: Option<[f64; 3]>,
    pub determinant: Option<f64>,
    pub orientation: Option<LinearTransformOrientation>,
    pub rotation_xyzw: Option<[f32; 4]>,
    pub uniform_scale: Option<f64>,
}

Deterministic facts derived from the linear 3x3 part of an affine matrix.

Numeric fields are present for every finite observation and absent only for LinearTransformClassification::NonFinite. uniform_scale is present when the columns are mutually orthogonal and have one common length, including reflected uniform transforms. Derived numeric fields use f64 so determinant products remain representable across finite f32 matrices.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

classification: LinearTransformClassification

Stable transform class.

axis_lengths: Option<[f64; 3]>

Lengths of the X, Y, and Z matrix columns.

determinant: Option<f64>

Determinant of the linear 3x3 matrix.

orientation: Option<LinearTransformOrientation>

Determinant sign, using the same relative singularity tolerance as the classification.

rotation_xyzw: Option<[f32; 4]>

Canonical XYZW proper-orthogonal polar rotation of the linear part, present exactly for a right-handed unit-orthonormal transform.

uniform_scale: Option<f64>

Common orthogonal axis length when one is well-defined.
