Struct bevy_math::cubic_splines::Bezier
source · pub struct Bezier<P: Point> { /* private fields */ }
Expand description
A spline composed of a series of cubic Bezier curves.
Useful for user-drawn curves with local control, or animation easing. See
CubicSegment::new_bezier
for use in easing.
Interpolation
The curve only passes through the first and last control point in each set of four points.
Tangency
Manually defined by the two intermediate control points within each set of four points.
Continuity
At minimum C0 continuous, up to C2. Continuity greater than C0 can result in a loss of local control over the spline due to the curvature constraints.
Usage
let points = [[
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
]];
let bezier = Bezier::new(points).to_curve();
let positions: Vec<_> = bezier.iter_positions(100).collect();
