Enum AnimationCurve 

pub enum AnimationCurve {
    Constant(f32),
    Keyframes(Vec<(f32, f32)>),
    MathDriven(MathFunction),
    BezierKeyframes(Vec<BezierKey>),
}

A single float channel over normalized time [0, 1].

Variants

Constant(f32)

Constant value.

Keyframes(Vec<(f32, f32)>)

Linear keyframes: list of (time, value) pairs sorted by time.

MathDriven(MathFunction)

Driven entirely by a MathFunction evaluated at time t.

BezierKeyframes(Vec<BezierKey>)

Cubic bezier keyframes: (time, value, in_tangent, out_tangent).

Implementations

impl AnimationCurve

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

Evaluate the curve at normalized time t in [0, 1].

pub fn constant(v: f32) -> Self

Build a constant curve.

pub fn linear(a: f32, b: f32) -> Self

Build a linear ramp from a at t=0 to b at t=1.

pub fn from_keys(keys: Vec<(f32, f32)>) -> Self

Build a curve from raw (time, value) pairs.
