pub fn intersect_analytic_pair(
first: &NurbsSurface,
second: &NurbsSurface,
tolerance: f64,
) -> Option<Vec<NurbsCurve>>Expand description
Exact intersection curves for recognized analytic pairs, or None when
the pair is not handled and the caller must fall back to SSI marching.
Some(vec![]) means “provably empty” and skips marching entirely.
