Struct gemini_engine::elements::geometry::Polygon

pub struct Polygon {
    pub points: Vec<Vec2D>,
    pub fill_char: ColChar,
}

The Polygon takes a vec of Vec2Ds and returns a polygon with those vertices when blit to a [View]

Fields

points: Vec<Vec2D>

fill_char: ColChar

Implementations

impl Polygon

pub fn new(points: Vec<Vec2D>, fill_char: ColChar) -> Self

pub fn triangulate(vertices: &[Vec2D]) -> Vec<[Vec2D; 3]>

Split a polygon up into triangles. Returns a vec of coordinate sets for said triangles

pub fn draw(vertices: &[Vec2D]) -> Vec<Vec2D>

Draw a polygon from points. Only supports convex polygons as of now

Trait Implementations

impl ViewElement for Polygon

fn active_pixels(&self) -> Vec<Point>

Return a vector of every coordinate where a pixel should be placed and its respective ColChar. If your whole object is a solid colour, consider using utils::points_to_pixels() which will add the same ColChar to every point and can then be used as this function’s output
