Struct TurningPoints 

pub struct TurningPoints {
    pub direction: Vector3,
    pub candidates: Vec<Candidate>,
    pub tangent: Vec<Candidate>,
}

What turning_points finds.

Fields

direction: Vector3

The direction the curves turn back along at the candidates: sharp, and a free choice (see [direction]).

candidates: Vec<Candidate>

One candidate per cluster of touching boxes left at the handoff, where the two surfaces’ normals are definitely not parallel: the sharp middle of one box of it, (u_a, v_a, u_b, v_b), a seed for Newton onto the curve, and the box of the whole cluster. Several turning points closer than the handoff come out as one candidate.

tangent: Vec<Candidate>

Clusters of the pairs of patches set aside because the normals could be parallel over them (see the module docs): where the surfaces may touch, along a curve, over an area or at isolated points, the nodes where branches cross (refine_node tells those apart).
