Struct Transform3 

pub struct Transform3<T: Float> {
    pub m: [[T; 3]; 3],
    pub t: Vec3<T>,
}

3×3 matrix + translation = affine transform in ℝ³.

Fields

m: [[T; 3]; 3]

3x3 matrix for the linear part of the transform

t: Vec3<T>

Translation vector

Implementations

impl<T: Float> Transform3<T>

pub fn identity() -> Self

Identity transform

pub fn new(m: [[T; 3]; 3], t: Vec3<T>) -> Self

Construct from 3×3 matrix and translation

pub fn transform_point(&self, p: Point3<T>) -> Point3<T>

Apply to a point: x ↦ M·x + t

pub fn transform_vec(&self, v: Vec3<T>) -> Vec3<T>

Apply to a vector (no translation)

pub fn inverse(&self) -> Option<Transform3<T>>

Invert (requires det(M) ≠ 0)

Trait Implementations

impl<T: Clone + Float> Clone for Transform3<T>

fn clone(&self) -> Transform3<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + Float> Debug for Transform3<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: PartialEq + Float> PartialEq for Transform3<T>

fn eq(&self, other: &Transform3<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
