Struct bevy::math::cubic_splines::CubicHermite
pub struct CubicHermite<P>where
P: VectorSpace,{ /* 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
Tangents are explicitly defined at each control point.
§Continuity
The curve is at minimum C0 continuous, meaning it has no holes or jumps. It is also C1, meaning the tangent vector has no sudden jumps.
§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 = CubicHermite::new(points, tangents).to_curve();
let positions: Vec<_> = hermite.iter_positions(100).collect();
