Implementations

impl<T> CubicBezier<T>

where T: Affine<Diff: Linear<Scalar = f32>> + Clone,

pub fn eval(&self, t: f32) -> T

Evaluates the value of self at t.

For t < 0, returns the first control point. For t > 1, returns the last control point. Uses De Casteljau’s algorithm.

pub fn fast_eval(&self, t: f32) -> T

Evaluates the value of self at t.

For t < 0, returns the first control point. For t > 1, returns the last control point.

Directly evaluates the cubic. Faster but possibly less numerically stable than Self::eval.

pub fn tangent(&self, t: f32) -> T::Diff

Returns the tangent, or direction vector, of self at t.

Clamps t to the range [0, 1].

Trait Implementations

impl<T: Clone> Clone for CubicBezier<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for CubicBezier<T>

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

Formats the value using the given formatter.

impl<T> Parametric<T> for CubicBezier<T>

where T: Affine<Diff: Linear<Scalar = f32> + Clone> + Clone,

fn eval(&self, t: f32) -> T

Returns the value of self at t.

impl<T: PartialEq> PartialEq for CubicBezier<T>

fn eq(&self, other: &CubicBezier<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.
