Struct CornerRounding 

pub struct CornerRounding {
    pub radius: f64,
    pub smoothing: f64,
}

How much, and how smoothly, a single vertex is rounded.

A corner is one of three things:

1. unrounded — CornerRounding::UNROUNDED, the vertex itself;
2. circular — smoothing == 0: one arc between the two adjacent edges;
3. smoothed — smoothing > 0: an inner arc plus two symmetric flanking curves carrying the arc out to the edges. At smoothing == 1 there is no arc left at all — the flanking curves meet in the middle.

radius is an absolute length in the polygon’s own coordinate space, so a shape authored in the canonical (-1, -1)..(1, 1) box wants radii relative to that box, not to its eventual on-screen size. Transforming the polygon scales the rounding with it.

Fields

radius: f64

Radius of the circle defining the corner’s inner arc; 0 is a sharp corner.

smoothing: f64

How far the arc is extended toward the adjacent edges, in 0..=1.

Implementations

impl CornerRounding

pub const UNROUNDED: CornerRounding

A sharp corner: the vertex itself, no arc.

pub fn radius(radius: f64) -> CornerRounding

A corner rounded by a circular arc of radius, with no smoothing.

Panics

If radius is negative.

pub fn new(radius: f64, smoothing: f64) -> CornerRounding

A corner rounded by an arc of radius, smoothed by smoothing.

Panics

If radius is negative or smoothing is outside 0..=1.
