This object is a one-stroke dense knot domain extruded into a closed 3D tube mesh, using the PAPP-OSG route from constrained path to validated woven geometry. Generated, not hand-modeled: the Dara Knot begins as a gate-constrained one-stroke path on a 32-grid dense circular domain, then is materialized as a Catmull–Rom ribbon and a 10-sided tube with parallel-transport framing and z-lift weaving. Its signature is maximum crossing density packed into a single closed oak-root knot field. Dara Knot is the most compact and crossing-rich of the set: a filled circular Celtic field built to maximize interlace density, so the eye reads not a single emblem but a continuous root-like network. Inspired by the oak-root Dara tradition, it behaves like a woven infrastructure inside a disc boundary, with compressed over/under rhythm, layered continuity, and strong visual depth.
