nx_gltf_anim.nx

nx_gltf_anim.nx -- ★SKINNED + ANIMATED glTF export: the being as a rigged, WALKING .glb (plays in any glTF viewer). Reuses our FK rig: each mesh vertex is rigidly bound to its nearest part's deepest bone (joints supplied by the driver). 9 joints (root + L/R shoulder,elbow,hip,knee) in a 2-level hierarchy; inverse-bind = translate(-pivot); a walk-cycle animation = per-bone quaternion rotation keyframes about X (sagittal). Includes an integer float32 + fixed-point encoder. GENERALIZED 2026-08-10 (ws=dance-motion): the writer is now gltf_anim_export_qtrack (caller-supplied full-quaternion track, any key count, any animation name) and gltf_anim_export is the walk-table wrapper over it -- ONE writer, two callers, so real mocap (nx_dance_emit) and the synthetic walk share every byte of container logic. license_tier: ORIGINAL
