Struct bevy_math::cubic_splines::CubicCardinalSpline
source · pub struct CubicCardinalSpline<P: VectorSpace> {
pub tension: f32,
pub control_points: Vec<P>,
}
Expand description
A spline interpolated continuously across the nearest four control points, with the position of
the curve specified at every control point and the tangents computed automatically. The associated CubicCurve
has one segment between each pair of adjacent control points.
Note the Catmull-Rom spline is a special case of Cardinal spline where the tension is 0.5.
§Interpolation
The curve passes through every control point.
§Tangency
Tangents are automatically computed based on the positions of control points.
§Continuity
The curve is at minimum C1, meaning that it is continuous (it has no holes or jumps), and its tangent vector is also well-defined everywhere, without 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 cardinal = CubicCardinalSpline::new(0.3, points).to_curve();
let positions: Vec<_> = cardinal.iter_positions(100).collect();
