ArcSegment2

ArcSegment2 is a two-dimensional arc segment in Cartesian coordinates. It is a type of segment that represents a part of a circle segment.

Constructors

You can create an ArcSegment2 object using the new method, which takes three arguments: the support circle segment, the source_radian and the target_radian of the arc segment.

let arc_segment_2 = ArcSegment2::new(
    CircleSegment2::new(Point2::new(0.0, 0.0), 3.0),
    0.0,
    3.0 / 2.0 * std::f64::consts::PI,
);

Fields

ArcSegment2 has three fields: support, source_radian and target_radian, which represent the support circle segment, the source radian and the target radian of the arc segment, respectively.

// impl Segment2 trait
let source = arc_segment_2.source();
let source_radian = arc_segment_2.source_radian();
let target = arc_segment_2.target();
let target_radian = arc_segment_2.target_radian();
let center = arc_segment_2.center();
let radius = arc_segment_2.radius();

Methods

ArcSegment2 has the following methods:

• monotone: Returns a monotone representation of the arc segment.
• is_top: Returns true if the arc segment is on the top side of the circle segment.

let arc_segments = arc_segment_2.monotone();
let is_top = arc_segment_2.is_top();
