Struct ChartCrossing 

pub struct ChartCrossing {
    pub edges: [(usize, usize); 2],
    pub parameters: [f64; 2],
    pub apart: [i64; 2],
    pub at: Point,
}

A point where a face’s boundary crosses itself in its surface’s chart.

Fields

edges: [(usize, usize); 2]

The two edges crossing, each as (wire, edge): the index of the wire among the face’s wires as stored, and of the edge in that wire’s order. The first comes first in that order.

parameters: [f64; 2]

Where on each edge’s pcurve, in that pcurve’s own parameter.

apart: [i64; 2]

Whole periods of the chart the second edge’s pcurve is moved by, against the first’s, to meet it there, beyond those the walk carries it by across the seam. Zero on a surface that does not close.

at: Point

Where, on the surface, placed as the face is.
