}

A piece of a region’s boundary in the plane’s 2D frame.

Variants

Segment(Point2, Point2)

A straight segment between two points.

Arc

The arc of the ellipse center + a cos t u + b sin t v for t from t0 to t1 (t0 < t1 <= t0 + 2 pi); a circle when a == b. u and v are orthonormal.

Fields

center: Point2

The ellipse’s center.

u: Vec2

The direction of the a axis.

v: Vec2

The direction of the b axis.

a: f64

The semi-axis along u.

b: f64

The semi-axis along v.

t0: f64

The arc’s first angle.

t1: f64

The arc’s last angle.
