about

nx_gltf_mesh.nx -- ★F6 ASSET IO (graphics foundation ladder): export the current nx_trimesh mesh as a standard binary glTF (.glb) -- POSITION (float32) + NORMAL (float32 VEC3, UNIT) + COLOR_0 (normalized uint8 VEC4) + indices (uint32), one PBR material, doubleSided. This makes our sovereign geometry a REAL, universally-readable 3D asset (Blender, web viewers, engines). 100% integer: includes an integer IEEE-754 float32 encoder. license_tier: ORIGINAL
