Struct rustracer::transformation::Transformation

pub struct Transformation {
    m: Matrix,
    invm: Matrix,
}

3D Homogeneous Transformation struct.

This class encodes an affine transformation.
It has been designed with the aim of making the calculation of the inverse transformation particularly efficient.

Fields

m: Matrix

Transformation matrix.

invm: Matrix

Inverse transformation matrix.

Implementations

impl Transformation

fn is_consistent(self) -> bool

Check the internal consistency of the transformation.

This method is useful when writing tests.

pub fn inverse(self) -> Self

Return a Transformation object representing the inverse affine transformation.

This method is very cheap to call.

Trait Implementations

impl Clone for Transformation

fn clone(&self) -> Transformation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transformation

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

Formats the value using the given formatter.

impl Default for Transformation

fn default() -> Transformation

Returns the “default value” for a type.

impl IsClose for Transformation

fn is_close(&self, other: Transformation) -> bool

Return true if matrix and inverse matrix of two Transformation are close.

impl Mul<Normal> for Transformation

type Output = Normal

The resulting type after applying the * operator.

fn mul(self, normal: Normal) -> Self::Output

Performs the * operation.

impl Mul<Point> for Transformation

type Output = Point

The resulting type after applying the * operator.

fn mul(self, point: Point) -> Self::Output

Performs the * operation.

impl Mul<Ray> for Transformation

type Output = Ray

The resulting type after applying the * operator.

fn mul(self, ray: Ray) -> Self::Output

Performs the * operation.

impl Mul<Vector> for Transformation

type Output = Vector

The resulting type after applying the * operator.

fn mul(self, vector: Vector) -> Self::Output

Performs the * operation.

impl Mul for Transformation

type Output = Transformation

The resulting type after applying the * operator.

fn mul(self, rhs: Transformation) -> Self::Output

Performs the * operation.

impl PartialEq for Transformation

fn eq(&self, other: &Transformation) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Transformation

impl StructuralPartialEq for Transformation
