Expand description
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§
source§impl Ellipse
impl Ellipse
sourcepub const fn new(half_width: f32, half_height: f32) -> Self
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.
sourcepub fn from_size(size: Vec2) -> Self
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.
sourcepub fn eccentricity(&self) -> f32
pub fn eccentricity(&self) -> f32
Returns the eccentricity of the ellipse. It can be thought of as a measure of how “stretched” or elongated the ellipse is.
The value should be in the range [0, 1), where 0 represents a circle, and 1 represents a parabola.
sourcepub fn focal_length(&self) -> f32
pub fn focal_length(&self) -> f32
Get the focal length of the ellipse. This corresponds to the distance between one of the foci and the center of the ellipse.
The focal length of an ellipse is related to its eccentricity by eccentricity = focal_length / semi_major
sourcepub fn semi_major(&self) -> f32
pub fn semi_major(&self) -> f32
Returns the length of the semi-major axis. This corresponds to the longest radius of the ellipse.
sourcepub fn semi_minor(&self) -> f32
pub fn semi_minor(&self) -> f32
Returns the length of the semi-minor axis. This corresponds to the shortest radius of the ellipse.
