pub fn classify_tangent_contact_at(
first: &NurbsSurface,
second: &NurbsSurface,
witness: Vec3,
tolerance: f64,
) -> Result<Option<TangentContact>, String>Expand description
Refine witness onto the tangential contact of the two carriers and
classify it. None when the witness is not near any contact (the
refinement leaves a residual above tolerance) or the carriers have no
curvature to classify by (two planes).
