Struct bevy_math::primitives::Ellipse

pub struct Ellipse {
    pub half_size: Vec2,
}

An ellipse primitive

Fields

half_size: Vec2

Half of the width and height of the ellipse.

This corresponds to the two perpendicular radii defining the ellipse.

Implementations

impl Ellipse

pub const fn new(half_width: f32, half_height: f32) -> Self

Create a new Ellipse from half of its width and height.

This corresponds to the two perpendicular radii defining the ellipse.

pub fn from_size(size: Vec2) -> Self

Create a new Ellipse from a given full size.

size.x is the diameter along the X axis, and size.y is the diameter along the Y axis.

pub fn semi_major(self) -> f32

Returns the length of the semi-major axis. This corresponds to the longest radius of the ellipse.

pub fn semi_minor(self) -> f32

Returns the length of the semi-minor axis. This corresponds to the shortest radius of the ellipse.

pub fn area(&self) -> f32

Get the area of the ellipse

Trait Implementations

impl Bounded2d for Ellipse

fn aabb_2d(&self, translation: Vec2, rotation: f32) -> Aabb2d

Get an axis-aligned bounding box for the shape with the given translation and rotation. The rotation is in radians, counterclockwise, with 0 meaning no rotation.

fn bounding_circle(&self, translation: Vec2, _rotation: f32) -> BoundingCircle

Get a bounding circle for the shape The rotation is in radians, counterclockwise, with 0 meaning no rotation.

impl Clone for Ellipse

fn clone(&self) -> Ellipse

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Ellipse

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Ellipse

fn default() -> Self

Returns the default Ellipse with a half-width of 1.0 and a half-height of 0.5.

impl<'de> Deserialize<'de> for Ellipse

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Ellipse

fn eq(&self, other: &Ellipse) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Ellipse

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Ellipse

impl Primitive2d for Ellipse

impl StructuralPartialEq for Ellipse
