Erratum: A Robust and Efficient Intersection Algorithm for NURBS Surfaces: Handling Small Loops and Tangent Intersections

A correction has been issued for a 2026 ACM Transactions on Graphics paper on NURBS surface intersection, specifically the version covering small loops and tangent intersections. For graphics teams working on CAD import, modeling, or robust geometry kernels, the update matters because these edge cases are exactly where intersection code tends to fail. The fix signals that the published method needed adjustment, not just a minor editorial pass.
