pub fn new(value: Vec4) -> Result<Dir4, InvalidDirectionError>

Create a Dir4 from a Vec4 that is already normalized.

Warning

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

pub fn new_and_length(value: Vec4) -> Result<(Dir4, f32), InvalidDirectionError>

Create a direction from a finite, nonzero Vec4, normalizing it and also returning its original length.

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

pub fn from_xyzw( x: f32, y: f32, z: f32, w: f32, ) -> Result<Dir4, InvalidDirectionError>

Create a direction from its x, y, z, and w components.

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

pub fn from_xyzw_unchecked(x: f32, y: f32, z: f32, w: f32) -> Dir4

Create a direction from its x, y, z, and w components, assuming the resulting vector is normalized.

pub const fn as_vec4(&self) -> Vec4

Returns the inner Vec4

pub fn fast_renormalize(self) -> Dir4

Returns self after an approximate normalization, assuming the value is already nearly normalized. Useful for preventing numerical error accumulation.
