Struct nalgebra::base::Unit

pub struct Unit<T> { /* private fields */ }

A wrapper that ensures the underlying algebraic entity has a unit norm.

It is likely that the only piece of documentation that you need in this page are:

• The construction with normalization
• Data extraction and construction without normalization
• Interpolation between two unit vectors

All the other impl blocks you will see in this page are about UnitComplex and UnitQuaternion; both built on top of Unit. If you are interested in their documentation, read their dedicated pages directly.

Implementations

impl<T, D, S> Unit<Vector<T, D, S>>

where T: Scalar, D: Dim, S: RawStorage<T, D, U1>,

pub fn cast<T2: Scalar>(self) -> Unit<OVector<T2, D>>

where T: Scalar, OVector<T2, D>: SupersetOf<Vector<T, D, S>>, DefaultAllocator: Allocator<T2, D, U1>,

Cast the components of self to another type.

Example

let v = Vector3::<f64>::y_axis();
let v2 = v.cast::<f32>();
assert_eq!(v2, Vector3::<f32>::y_axis());

impl<T: Normed> Unit<T>

Construction with normalization

pub fn new_normalize(value: T) -> Self

Normalize the given vector and return it wrapped on a Unit structure.

pub fn try_new(value: T, min_norm: T::Norm) -> Option<Self>

where T::Norm: RealField,

Attempts to normalize the given vector and return it wrapped on a Unit structure.

Returns None if the norm was smaller or equal to min_norm.

pub fn new_and_get(value: T) -> (Self, T::Norm)

Normalize the given vector and return it wrapped on a Unit structure and its norm.

pub fn try_new_and_get(value: T, min_norm: T::Norm) -> Option<(Self, T::Norm)>

where T::Norm: RealField,

Normalize the given vector and return it wrapped on a Unit structure and its norm.

Returns None if the norm was smaller or equal to min_norm.

pub fn renormalize(&mut self) -> T::Norm

Normalizes this vector again. This is useful when repeated computations might cause a drift in the norm because of float inaccuracies.

Returns the norm before re-normalization. See .renormalize_fast for a faster alternative that may be slightly less accurate if self drifted significantly from having a unit length.

pub fn renormalize_fast(&mut self)

Normalizes this vector again using a first-order Taylor approximation. This is useful when repeated computations might cause a drift in the norm because of float inaccuracies.

impl<T> Unit<T>

Data extraction and construction without normalization

pub const fn new_unchecked(value: T) -> Self

Wraps the given value, assuming it is already normalized.

pub fn from_ref_unchecked(value: &T) -> &Self

Wraps the given reference, assuming it is already normalized.

pub fn into_inner(self) -> T

Retrieves the underlying value.

pub fn unwrap(self) -> T

👎Deprecated: use .into_inner() instead

Retrieves the underlying value. Deprecated: use Unit::into_inner instead.

pub fn as_mut_unchecked(&mut self) -> &mut T

Returns a mutable reference to the underlying value. This is _unchecked because modifying the underlying value in such a way that it no longer has unit length may lead to unexpected results.

Builds a left-handed look-at view matrix without translation.

It maps the view direction dir to the positive z axis. This conforms to the common notion of left handed look-at matrix from the computer graphics community.

Arguments

• dir − The view direction. It does not need to be normalized.
• up - A vector approximately aligned with required the vertical axis. The only requirement of this parameter is to not be collinear to dir.

Example

let dir = Vector3::new(1.0, 2.0, 3.0);
let up = Vector3::y();

let q = UnitQuaternion::look_at_lh(&dir, &up);
assert_relative_eq!(q * dir.normalize(), Vector3::z());

pub fn from_basis_unchecked(basis: &[Vector2<T>; 2]) -> Self

Builds a rotation from a basis assumed to be orthonormal.

In order to get a valid unit-quaternion, the input must be an orthonormal basis, i.e., all vectors are normalized, and the are all orthogonal to each other. These invariants are not checked by this method.

pub fn from_matrix(m: &Matrix2<T>) -> Self

where T: RealField,

Builds an unit complex by extracting the rotation part of the given transformation m.

This is an iterative method. See .from_matrix_eps to provide mover convergence parameters and starting solution. This implements “A Robust Method to Extract the Rotational Part of Deformations” by Müller et al.

• max_iter: the maximum number of iterations. Loops indefinitely until convergence if set to 0.
• guess: an estimate of the solution. Convergence will be significantly faster if an initial solution close to the actual solution is provided. Can be set to UnitQuaternion::identity() if no other guesses come to mind.

pub fn rotation_to(&self, other: &Self) -> Self

The result is such that: self.rotation_to(other) * self == other.
