CircularSector

CircularSector

  • arc : bevy_math::primitives::dim2::Arc2d

Description

A primitive representing a circular sector: a pie slice of a circle.

The segment is positioned so that it always includes [Vec2::Y] and is vertically symmetrical. To orient the sector differently, apply a rotation. The sector is drawn with the center of its circle at the origin [Vec2::ZERO].

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

Functions

FunctionSummary
angle(_self) Get the angle of the sector
apothem(_self) Get the length of the apothem of this sector See [`Arc2d::apothem`]
arc_length(_self) Get the length of the arc defining the sector
chord_length(_self) Get the length of the chord defined by the sector See [`Arc2d::chord_length`]
chord_midpoint(_self) Get the midpoint of the chord defined by the sector See [`Arc2d::chord_midpoint`]
clone(_self)No Documentation 🚧
eq(_self, other)No Documentation 🚧
from_degrees(radius, angle) Create a new [`CircularSector`] from a `radius` and an `angle` in degrees.
from_radians(radius, angle) Create a new [`CircularSector`] from a `radius` and an `angle` in radians.
from_turns(radius, fraction) Create a new [`CircularSector`] from a `radius` and a number of `turns` of a circle. For instance, `0.5` turns is a semicircle.
half_angle(_self) Get half the angle of the sector
half_chord_length(_self) Get half the length of the chord defined by the sector See [`Arc2d::half_chord_length`]
new(radius, angle) Create a new [`CircularSector`] from a `radius` and an `angle`
radius(_self) Get the radius of the sector
sagitta(_self) Get the length of the sagitta of this sector See [`Arc2d::sagitta`]
