Struct LoopCrossing 

pub struct LoopCrossing {
    pub face: u64,
    pub face_name: Option<String>,
    pub loop_id: u64,
    pub coedge_a: u64,
    pub coedge_b: u64,
    pub edge_a: u64,
    pub edge_b: u64,
    pub uv: [f64; 2],
    pub point: Vec3,
}

One place a face’s trim loop crosses ITSELF in the face’s parameter domain.

The two coedges are the loop’s own — a bowtie between two different trims, or one pcurve crossing itself, in which case they are the same coedge.

Fields

face: u64

face_name: Option<String>

loop_id: u64

coedge_a: u64

The two crossing coedges, in loop order.

coedge_b: u64

edge_a: u64

The edges those coedges use — what a caller NAMES the defect by, since an edge survives the surgery that renumbers coedges.

edge_b: u64

uv: [f64; 2]

Where they cross, in the face’s own domain (wrapped into it on a periodic direction, so it is a parameter the surface can be evaluated at rather than a covering-plane lift).

point: Vec3

The surface point there — the 3D place the face passes through itself.
