[−][src]Function pareen::lerp
pub fn lerp<T, V, W, F, G, A, B>(a: A, b: B) -> Anim<impl Fun<T = T, V = V>> where
T: Copy + Mul<W, Output = W>,
V: Copy + Add<W, Output = V> + Sub<Output = W>,
F: Fun<T = T, V = V>,
G: Fun<T = T, V = V>,
A: Into<Anim<F>>,
B: Into<Anim<G>>,
Linearly interpolate between two animations, starting at time zero and finishing at time one.
This is a wrapper around Anim::lerp
for
convenience, allowing automatic conversion into Anim
for both a
and b
.
Example
Linearly interpolate between two constant values:
let anim = pareen::lerp(5.0f32, 10.0); assert_approx_eq!(anim.eval(0.0f32), 5.0); assert_approx_eq!(anim.eval(0.5), 7.5); assert_approx_eq!(anim.eval(1.0), 10.0); assert_approx_eq!(anim.eval(2.0), 15.0);
