We introduce a training-free approach that accelerates 4D mesh generation while improving temporal correspondence quality. Our key observation is that temporal correspondences emerge inside a 4D backbone long before its generated meshes become visually accurate. We exploit this with a general framework we call Spatio-Temporal Attention Chain which propagates information across spa","authors_text":"Dvir Samuel, Gal Chechik, Yoni Kasten, Yuval Atzmon","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.CV","submitted_at":"2026-05-19T12:51:50Z","title":"Fast 4D Mesh Generation by Spatio-Temporal Attention Chains"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.19786","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:323b9904c618eabe656e50961007f7ff5117e08cb619c0a21a3d2e7ba4619a42","target":"record","created_at":"2026-05-20T01:06:13Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c17e689a6aae65cabc2ec9ae40f7d0cb6397186a9b6707bb28e3251fe8168f6a","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.CV","submitted_at":"2026-05-19T12:51:50Z","title_canon_sha256":"ad94deeeca151d9e0e8d0e054b505a2f106b64e1e1eec9e1821b21e9234b9514"},"schema_version":"1.0","source":{"id":"2605.19786","kind":"arxiv","version":1}},"canonical_sha256":"473f4f5bdaae9248ff05d1a7a9e530c3ac9dd652a264d5f453133a5626c05d5d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"473f4f5bdaae9248ff05d1a7a9e530c3ac9dd652a264d5f453133a5626c05d5d","first_computed_at":"2026-05-20T01:06:13.949268Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T01:06:13.949268Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"B807Itikf5zYkkBU89isDexnUofBZuRw8HNu7vrT9u7Fy1V54CgEHBTtPEu0AvsH26+GNNXaYQ+3lMBleXSrBg==","signature_status":"signed_v1","signed_at":"2026-05-20T01:06:13.950219Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.19786","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:323b9904c618eabe656e50961007f7ff5117e08cb619c0a21a3d2e7ba4619a42","sha256:f8bcf9cdf8134531e9365baf18621eb1def3471ff142ae9df37e73a7e9de3f87"],"state_sha256":"35419d49ca96efc4cb21b828fcf8a752c5ab7835fc53346af749114f0a25e9dd"}
