Struct CircularSegment 

pub struct CircularSegment {
    pub arc: Arc2d,
}

A primitive representing a circular segment: the area enclosed by the arc of a circle and its chord (the line between its endpoints).

The segment is drawn starting from Vec2::Y, extending equally on either side. To orient the segment differently, apply a rotation. The segment is drawn with the center of its circle at the origin Vec2::ZERO. When positioning a segment, the apothem function may be particularly useful.

Warning: Circular segments with negative angle or radius, or with angle greater than an entire circle, are not officially supported. We recommend normalizing circular segments to have an angle in [0, 2π].

Fields

arc: Arc2d

The arc defining the segment
