Struct bevy_math::cubic_splines::Hermite
source · pub struct Hermite<P: Point> { /* private fields */ }
Expand description
A spline interpolated continuously between the nearest two control points, with the position and velocity of the curve specified at both control points. This curve passes through all control points, with the specified velocity which includes direction and parametric speed.
Useful for smooth interpolation when you know the position and velocity at two points in time, such as network prediction.
Interpolation
The curve passes through every control point.
Tangency
Explicitly defined at each control point.
Continuity
At minimum C0 continuous, up to C1.
Usage
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
let tangents = [
vec2(0.0, 1.0),
vec2(0.0, 1.0),
vec2(0.0, 1.0),
vec2(0.0, 1.0),
];
let hermite = Hermite::new(points, tangents).to_curve();
let positions: Vec<_> = hermite.iter_positions(100).collect();
