Line3

data class Line3(val direction: Vec3, val moment: Vec3, val precision: DoubleEquivalence = DEFAULT_DOUBLE_EQUIVALENCE) : Line<Vector3<*>> (source)

Represents a line in 3D space defined by a direction vector and a moment (point offset).

The line is stored in Plücker form using a unit direction vector and a moment vector computed as point × direction for any point on the line. The distance to the line is the magnitude of the perpendicular offset vector. Since a 3D line does not divide space into two half-spaces, offset and location use a deterministic auxiliary orientation to choose a sign; that sign is a classification convention, not a geometric side of the line.
