Struct Transform 

pub struct Transform {
    pub from: Placement,
    pub to: Placement,
}

An item-defined transformation as two frames: the relative transform maps from (transform_item_1) to to (transform_item_2) — the faithful two-frame form; Transform::matrix composes them on demand.

Fields

from: Placement

to: Placement

Implementations

impl Transform

pub fn matrix(&self) -> Option<[[f64; 4]; 4]>

The relative placement composed into one homogeneous 4×4 matrix — an opt-in derived view of the two stored frames (M = F_to · F_from⁻¹: geometry defined in the from frame lands in the to frame).

Convention: m[row][col], points map as column vectors p' = M · p, and the last row is [0, 0, 0, 1] (STEP placements carry rotation and translation only). None if either placement is degenerate (a zero axis, or a reference direction parallel to the axis) — the matrix is not fabricated from bad frames.
