pub fn point_to_f64(p: &ImplicitPoint) -> Option<[f64; 3]>Expand description
Materialize an implicit point to f64 via the FIXED-width (I1024) homogeneous
lambda — the fast path for the BigRational rational::point_of. The lambda is
computed in the gi-scaled domain (coords × 2^16), so the real coordinate is
lambda[k] / (d · 2^16). Returns None on off-grid coords / overflow, where
the caller falls back to the exact BigRational materialization. Used for the
classifier centroids AND the output verts (the dominant per-op cost).
