Struct Polygon2 

pub struct Polygon2 {
    pub vertices: VecDeque<Vec2>,
}

Fields

vertices: VecDeque<Vec2>

Implementations

impl Polygon2

pub fn terminal(&self, terminal: PolygonTerminal) -> Option<Vec2>

Returns the terminal vertex of the polygon, or None if the polygon is empty.

pub fn extend_by_line( &mut self, terminal: PolygonTerminal, other_line_end: Vec2, )

Extends the polygon by a line from the terminal vertex to other_line_end.

pub fn merge_polygon( &mut self, my_terminal: PolygonTerminal, other: Polygon2, other_terminal: PolygonTerminal, )

This assumes that the polygon to be merged doesn’t contain any vertices that are already part of this polygon.

pub fn is_closed(&self) -> bool

Returns true if the polygon is closed (the terminal vertex is the same as the first vertex).

pub fn close(&mut self)

Closes the polygon by adding the terminal vertex to the front if it is not already closed.

pub fn length(&self) -> f32

Returns the length (cumulative distance between vertices) of the polygon.

pub fn min_max(&self) -> (Vec2, Vec2)

Returns the minimum and maximum coordinates of the polygon.

The minimum is the smallest x and y values, and the maximum is the largest x and y values. The pair forms an AABB (axis-aligned bounding box) that encloses the polygon.

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

Wether a point is inside the polygon.

Assumes that the polygon is closed.
