Struct LineArtLayer 

Source 
pub struct LineArtLayer {
    pub ground: [f64; 4],
    pub fills: Vec<([[f64; 2]; 3], bool)>,
    pub outlines: Vec<(Vec<[f64; 2]>, bool)>,
    pub arrows: Vec<([f64; 2], [f64; 2])>,
}
Expand description

What a Line art instructions picture draws beyond its lines (paper mm): a light grey ground under the picture, the parts’ visible faces as flat triangles painted back to front (white where an earlier step placed the part, blue where the step adds it), each part’s outline in its tier’s heavier ink, and the insertion arrows (a thin black line from where the part starts to its seat, a filled black head at the seat).

Fields§

§ground: [f64; 4]

[x0, y0, x1, y1].

§fills: Vec<([[f64; 2]; 3], bool)>

Back to front; true for a part the step adds.

§outlines: Vec<(Vec<[f64; 2]>, bool)>

Outline runs; true for a part the step adds.

§arrows: Vec<([f64; 2], [f64; 2])>

(tail, tip): the head’s point is at the tip.
