Struct gemini_engine::elements::Triangle

pub struct Triangle {
    pub pos0: Vec2D,
    pub pos1: Vec2D,
    pub pos2: Vec2D,
    pub fill_char: ColChar,
    /* private fields */
}

The Triangle takes three Vec2Ds and returns a triangle with those vertices when blit to a View

Fields

pos0: Vec2D

pos1: Vec2D

pos2: Vec2D

fill_char: ColChar

Implementations

impl Triangle

pub const fn new( pos0: Vec2D, pos1: Vec2D, pos2: Vec2D, fill_char: ColChar ) -> Self

pub const fn with_array(points: &[Vec2D], fill_char: ColChar) -> Self

Takes the corners of the triangle as an array rather than as separate parameters

pub fn generate_cache(&mut self)

Generate a BlitCache if you intend for the triangle to not move across multiple frames. If you use this, you MUST call generate_cache if the triangle does move in the future. This function will not generate a new cache if the previously generated cache is still valid

pub fn corners(&self) -> [Vec2D; 3]

Return the triangle’s points as an array

pub fn draw(corners: [Vec2D; 3]) -> Vec<Vec2D>

Takes three corner Vec2Ds and returns the points you should plot to the screen to make a triangle

Trait Implementations

impl ViewElement for Triangle

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
