#[repr(C)]
pub struct Similarity<T, R, const D: usize> { pub isometry: Isometry<T, R, D>, // some fields omitted }
Expand description

A similarity, i.e., an uniform scaling, followed by a rotation, followed by a translation.

Fields

isometry: Isometry<T, R, D>

The part of this similarity that does not include the scaling factor.

Implementations

Creates a new similarity from its rotational and translational parts.

Creates a new similarity from its rotational and translational parts.

The scaling factor of this similarity transformation.

The scaling factor of this similarity transformation.

Creates a new similarity that applies only a scaling factor.

Inverts self.

Inverts self in-place.

The similarity transformation that applies a scaling factor scaling before self.

The similarity transformation that applies a scaling factor scaling after self.

Sets self to the similarity transformation that applies a scaling factor scaling before self.

Sets self to the similarity transformation that applies a scaling factor scaling after self.

Appends to self the given translation in-place.

Appends to self the given rotation in-place.

Appends in-place to self a rotation centered at the point p, i.e., the rotation that lets p invariant.

Appends in-place to self a rotation centered at the point with coordinates self.translation.

Transform the given point by this similarity.

This is the same as the multiplication self * pt.

Example
let axisangle = Vector3::y() * f32::consts::FRAC_PI_2;
let translation = Vector3::new(1.0, 2.0, 3.0);
let sim = Similarity3::new(translation, axisangle, 3.0);
let transformed_point = sim.transform_point(&Point3::new(4.0, 5.0, 6.0));
assert_relative_eq!(transformed_point, Point3::new(19.0, 17.0, -9.0), epsilon = 1.0e-5);

Transform the given vector by this similarity, ignoring the translational component.

This is the same as the multiplication self * t.

Example
let axisangle = Vector3::y() * f32::consts::FRAC_PI_2;
let translation = Vector3::new(1.0, 2.0, 3.0);
let sim = Similarity3::new(translation, axisangle, 3.0);
let transformed_vector = sim.transform_vector(&Vector3::new(4.0, 5.0, 6.0));
assert_relative_eq!(transformed_vector, Vector3::new(18.0, 15.0, -12.0), epsilon = 1.0e-5);

Transform the given point by the inverse of this similarity. This may be cheaper than inverting the similarity and then transforming the given point.

Example
let axisangle = Vector3::y() * f32::consts::FRAC_PI_2;
let translation = Vector3::new(1.0, 2.0, 3.0);
let sim = Similarity3::new(translation, axisangle, 2.0);
let transformed_point = sim.inverse_transform_point(&Point3::new(4.0, 5.0, 6.0));
assert_relative_eq!(transformed_point, Point3::new(-1.5, 1.5, 1.5), epsilon = 1.0e-5);

Transform the given vector by the inverse of this similarity, ignoring the translational component. This may be cheaper than inverting the similarity and then transforming the given vector.

Example
let axisangle = Vector3::y() * f32::consts::FRAC_PI_2;
let translation = Vector3::new(1.0, 2.0, 3.0);
let sim = Similarity3::new(translation, axisangle, 2.0);
let transformed_vector = sim.inverse_transform_vector(&Vector3::new(4.0, 5.0, 6.0));
assert_relative_eq!(transformed_vector, Vector3::new(-3.0, 2.5, 2.0), epsilon = 1.0e-5);

Example

let sim = Similarity2::identity();
let pt = Point2::new(1.0, 2.0);
assert_eq!(sim * pt, pt);

let sim = Similarity3::identity();
let pt = Point3::new(1.0, 2.0, 3.0);
assert_eq!(sim * pt, pt);

Example
let rot = UnitComplex::new(f32::consts::FRAC_PI_2);
let pt = Point2::new(3.0, 2.0);
let sim = Similarity2::rotation_wrt_point(rot, pt, 4.0);

assert_relative_eq!(sim * Point2::new(1.0, 2.0), Point2::new(-3.0, 3.0), epsilon = 1.0e-6);

Creates a new similarity from a translation, a rotation, and an uniform scaling factor.

Example
let sim = SimilarityMatrix2::new(Vector2::new(1.0, 2.0), f32::consts::FRAC_PI_2, 3.0);

assert_relative_eq!(sim * Point2::new(2.0, 4.0), Point2::new(-11.0, 8.0), epsilon = 1.0e-6);

Example
let sim = SimilarityMatrix2::<f64>::identity();
let sim2 = sim.cast::<f32>();
assert_eq!(sim2, SimilarityMatrix2::<f32>::identity());

Creates a new similarity from a translation and a rotation angle.

Example
let sim = Similarity2::new(Vector2::new(1.0, 2.0), f32::consts::FRAC_PI_2, 3.0);

assert_relative_eq!(sim * Point2::new(2.0, 4.0), Point2::new(-11.0, 8.0), epsilon = 1.0e-6);

assert_relative_eq!(sim * vec, Vector3::new(18.0, 15.0, -12.0), epsilon = 1.0e-5);

Example

let sim2 = sim.cast::<f32>();
assert_eq!(sim2, Similarity3::<f32>::identity());

Creates an similarity that corresponds to a scaling factor and a local frame of an observer standing at the point eye and looking toward target.

It maps the view direction target - eye to the positive z axis and the origin to the eye.

Arguments
  • eye - The observer position.
  • target - The target position.
  • up - Vertical direction. The only requirement of this parameter is to not be collinear to eye - at. Non-collinearity is not checked.
Example
let eye = Point3::new(1.0, 2.0, 3.0);
let target = Point3::new(2.0, 2.0, 3.0);
let up = Vector3::y();

// Similarity with its rotation part represented as a UnitQuaternion
let sim = Similarity3::face_towards(&eye, &target, &up, 3.0);
assert_eq!(sim * Point3::origin(), eye);
assert_relative_eq!(sim * Vector3::z(), Vector3::x() * 3.0, epsilon = 1.0e-6);

// Similarity with its rotation part represented as Rotation3 (a 3x3 rotation matrix).
let sim = SimilarityMatrix3::face_towards(&eye, &target, &up, 3.0);
assert_eq!(sim * Point3::origin(), eye);
assert_relative_eq!(sim * Vector3::z(), Vector3::x() * 3.0, epsilon = 1.0e-6);
