about

nx_gltf_load.nx -- ★sovereign glTF (.glb) LOADER: parse a binary glTF back into nx_trimesh buffers, so the Nishi stack (Nishi OS / Nishi browser) can NATIVELY VIEW a .glb -- and so we can render our own exports on our own renderer to prove the round-trip (the honest-scope gap: "eyeball the model sovereignly"). Inverse of nx_gltf_mesh: includes an integer IEEE-754 float32 DECODER. Loads POSITION + COLOR_0 + indices from our exporter's layout; recomputes normals. license_tier: ORIGINAL
