about

nx_garment_twin.nx -- THE GARMENT PREVIEW: a print placed on a lit, procedurally knitted cotton front (2026-08-24, /compare/phototwin PT5: gt_print_place). license_tier: ORIGINAL No hw writes (Rule 26). nx_garment_twin place <print.img> <out.png> [conf] -> the flat-front preview PNG + a stats line + verdict=PLACED EXIT: 0 PLACED | 2 usage | 3 UNOBSERVABLE (undecodable print, unreadable conf, unwritable output) WHAT IT IS, HONESTLY. A FLAT-FRONT preview: the print is multiplied onto the fabric albedo (ink is subtractive: it can only darken cotton, never brighten it) and the whole front is shaded by a procedural jersey-knit relief (wale and course pitch, relief depth, ambient floor -- all conf rows) under an upper-left light, so the print reads as ink on a knitted surface rather than a flat composite. It is NOT a mesh drape: a body-on-mesh render is the next rung (gt_drape_mesh), declared, not implied. Every number is in knowledge/garment_twin.conf, and the fabric albedo rows are DECLARED until the bench swatch (PT7) measures the real blank -- the conf says so.
