pub fn new(value: Vec3) -> Result<Dir3, InvalidDirectionError>

Create a direction from a finite, nonzero Vec3.

Returns Err(InvalidDirectionError) if the length of the given vector is zero (or very close to zero), infinite, or NaN.

pub fn new_unchecked(value: Vec3) -> Dir3

Warning

value must be normalized, i.e its length must be 1.0.

pub fn any_orthogonal_vector(&self) -> Vec3

Returns some vector that is orthogonal to the given one.

Returns any unit vector that is orthogonal to the given one.

Panics

Will panic if self is not normalized when glam_assert is enabled.

pub fn any_orthonormal_pair(&self) -> (Vec3, Vec3)

Given a unit vector return two other vectors that together form an orthonormal basis. That is, all three vectors are orthogonal to each other and are normalized.
