This is a one-stroke cross-shaped knot domain transformed into a closed tubular mesh with woven crossings and verified topology. Generated, not hand-modeled: the Celtic Cross starts as a gate-constrained one-stroke path on a 30-grid cross domain, then becomes a Catmull–Rom ribbon and a 10-sided tube via parallel-transport framing and z-lift weaving. Its unique mechanism is a ring inscribed into four arms, with knotwork continuously filling both the circle and the axial cross The generator builds it as a circular ring inscribed in a four-arm cross, then fills both the ring and the arms with continuous knotwork so the form reads as one braided spatial system. In 3D, the Celtic Cross gains a strong ceremonial mass: the central ring stabilizes the object while the four arms extend as balanced directional axes, giving the piece the presence of a carved ritual sign translated into full volumetric topology.
