pub fn smooth(points: &[[f32; 2]], closed: bool, steps: usize) -> Vec<[f32; 2]>Expand description
A smooth curve through points, as straight pieces: steps of them
between two neighbouring points. It passes through every point (a
Catmull-Rom spline), so a path clicked corner by corner becomes the curve
a bent strip makes. A closed curve runs back round to the first point.
