Implementations§

source§

impl BoundingCircle

source

pub fn new(center: Vec2, radius: f32) -> Self

Constructs a bounding circle from its center and radius.

source

pub fn from_point_cloud( translation: Vec2, rotation: f32, points: &[Vec2] ) -> BoundingCircle

Computes a BoundingCircle containing the given set of points, transformed by translation and rotation.

The bounding circle is not guaranteed to be the smallest possible.

source

pub fn radius(&self) -> f32

Get the radius of the bounding circle

source

pub fn aabb_2d(&self) -> Aabb2d

Computes the smallest Aabb2d containing this BoundingCircle.

source

pub fn closest_point(&self, point: Vec2) -> Vec2

Finds the point on the bounding circle that is closest to the given point.

If the point is outside the circle, the returned point will be on the perimeter of the circle. Otherwise, it will be inside the circle and returned as is.

Trait Implementations§

impl BoundingVolume for BoundingCircle

§

type Position = Vec2

The position type used for the volume. This should be Vec2 for 2D and Vec3 for 3D.
§

type HalfSize = f32

The type used for the size of the bounding volume. Usually a half size. For example an f32 radius for a circle, or a Vec3 with half sizes for x, y and z for a 3D axis-aligned bounding box
source§

fn center(&self) -> Self::Position

Returns the center of the bounding volume.
source§

fn half_size(&self) -> Self::HalfSize

Returns the half size of the bounding volume.
source§

fn visible_area(&self) -> f32

Computes the visible surface area of the bounding volume. This method can be useful to make decisions about merging bounding volumes, using a Surface Area Heuristic. Read more

source§

fn merge(&self, other: &Self) -> Self
