Struct bevy_math::primitives::Arc2d
source · pub struct Arc2d {
pub radius: f32,
pub half_angle: f32,
}
Expand description
A primitive representing an arc between two points on a circle.
An arc has no area.
If you want to include the portion of a circle’s area swept out by the arc,
use the pie-shaped CircularSector
.
If you want to include only the space inside the convex hull of the arc,
use the bowl-shaped CircularSegment
.
The arc is drawn starting from Vec2::Y
, extending by half_angle
radians on
either side. The center of the circle is the origin Vec2::ZERO
. Note that this
means that the origin may not be within the Arc2d
’s convex hull.
Warning: Arcs with negative angle or radius, or with angle greater than an entire circle, are not officially supported. It is recommended to normalize arcs to have an angle in [0, 2π].
Fields§
§radius: f32
The radius of the circle
half_angle: f32
Half the angle defining the arc
