impl Outline

Source

pub fn new(vertices: impl Iterator<Item = Vec2>) -> Self

Creates new outline.

§Arguments
  • vertices - iterator of vertices. They MUST follow in order, which guarantee:
  1. when follow from i to i+1 vertex, inner area of polygon MUST be at left side;
Source

pub fn prev_that_next(&self, i: isize) -> (Vec2, Vec2, Vec2)

Tuple of (i-1, i, i+1) vertices;

  • i - index of vertex. May be negative;
Source

pub fn to_neighbors(&self, i: isize) -> (Vec2, Vec2)

Tuple of vectors to previous and to next vertex for i-th vertex;

  • i - index of vertex. May be negative;
Source

pub fn convex(&self, i: isize) -> bool

Test if angle is convex;

  • i - index of vertex. May be negative;
Source

pub fn concave(&self, i: isize) -> bool

Test if angle is concave;

  • i - index of vertex. May be negative;
Source

pub fn inner_angle_cos_sin(&self, i: isize) -> (f32, f32)

sin() and cos() for counter-clockwise angle between vector to next vertex and vector to previous.

§Arguments
  • i - index of vertex. May be negative;
Source

pub fn inner_angle(&self, i: isize) -> f32

Inner angle for vertex i-th vertex

§Arguments
  • i - index of vertex. May be negative;
Source

pub fn outer_angle(&self, i: isize) -> f32

Outer angle for vertex i-th vertex

§Arguments
  • i - index of vertex. May be negative;
