pub fn turning_points(
a: &NurbSurface3D,
b: &NurbSurface3D,
max_nodes: usize,
) -> GeopResult<TurningPoints>Expand description
Candidates for every point at which the curves a and b meet in turn
back along a direction chosen here — at least two on every closed loop
of them (see the module docs). Errors once max_nodes pairs of patches
have been searched with pairs left: a search that did not finish proves
nothing.
