about

nx_meshgen.nx -- sovereign SURFACE NETS: turn ANY signed-distance FIELD into a watertight triangle MESH (generator-path R1, operator 2026-07-04: the ecosystem must EMIT geometry, not hand-craft). This is the BRIDGE: the pioneer SDF (sdf_body/sdf_head) -- or a t2mesh/i2mesh-generated field -- becomes real emitted verts+faces. Dual method (naive surface nets): (1) each grid CUBE straddling the 0-surface gets ONE vertex at the mean of its edge zero-crossings; (2) each grid EDGE that crosses the surface emits a QUAD (2 tris) linking the 4 cubes around it. Integer fx1024; deterministic. license_tier: ORIGINAL
