Trait Implementations

impl<S, R, E: BaseFloat> ApproxEq for Decomposed<S, R>where S: ApproxEq<Epsilon = E> + VectorSpace, S::Scalar: ApproxEq<Epsilon = E>, R: ApproxEq<Epsilon = E>,

type Epsilon = E

Used for specifying relative comparisons.

fn default_epsilon() -> E

The default tolerance to use when testing values that are close together.

fn default_max_relative() -> E

The default relative tolerance for testing values that are far-apart.

fn default_max_ulps() -> u32

The default ULPs to tolerate when testing values that are far-apart.

fn relative_eq(&self, other: &Self, epsilon: E, max_relative: E) -> bool

A test for equality that uses a relative comparison if the values are far apart.

fn ulps_eq(&self, other: &Self, epsilon: E, max_ulps: u32) -> bool

A test for equality that uses units in the last place (ULP) if the values are far apart.

fn relative_ne( &self, other: &Self, epsilon: Self::Epsilon, max_relative: Self::Epsilon ) -> bool

The inverse of ApproxEq::relative_eq.

fn ulps_ne(&self, other: &Self, epsilon: Self::Epsilon, max_ulps: u32) -> bool

The inverse of ApproxEq::ulps_eq.

impl<V: Clone + VectorSpace, R: Clone> Clone for Decomposed<V, R>where V::Scalar: Clone,

fn clone(&self) -> Decomposed<V, R>

impl<P: EuclideanSpace, R: Rotation<P>> Transform<P> for Decomposed<P::Diff, R>where P::Scalar: BaseFloat, P::Diff: VectorSpace,

fn one() -> Decomposed<P::Diff, R>

Create an identity transformation. That is, a transformation which does nothing.

fn look_at(eye: P, center: P, up: P::Diff) -> Decomposed<P::Diff, R>

Create a transformation that rotates a vector to look at center from eye, using up for orientation.
