In this work, we study the light transport behavior within a sub-path that is comprised of a specular chain and two non-specular separators. We show that the specular manifolds formed by all the sub-paths could be exploited to provide coherence among sub-paths. By reconstructing continuous energy distributions from historical and coherent sub-paths, seed chains can be generat","authors_text":"Changqing Zou, Jie Guo, Ling-Qi Yan, Pengpei Hong, Yanwen Guo, Zhimin Fan","cross_cats":["cs.GR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2023-09-24T14:07:31Z","title":"Manifold Path Guiding for Importance Sampling Specular Chains"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2311.12818","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":"sha256:189f5008846e38b6cda9444916cf3ecec773a8ed4b1c5badeb6c70b0068df07d","target":"record","created_at":"2026-07-05T07:15:18Z","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":"f63b954c738f43309672dde401dff1287b56c4df36c5a0167e6befa184e5132d","cross_cats_sorted":["cs.GR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2023-09-24T14:07:31Z","title_canon_sha256":"455bce66f57cc00eba603ee965d984e3e1e043d39399c8874b3fd11f18afb819"},"schema_version":"1.0","source":{"id":"2311.12818","kind":"arxiv","version":1}},"canonical_sha256":"9963de5e9110390ada17b01605f55fe1172164eceefe2f0f6615854496ab6dec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9963de5e9110390ada17b01605f55fe1172164eceefe2f0f6615854496ab6dec","first_computed_at":"2026-07-05T07:15:18.910238Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:15:18.910238Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hBKyHRc9eeSDfZWQ5Jss2haanyVug08SbWfgQY1LMNmyfmVEdXlkMtIJSrDgV5g8dLSKjLrLKILFe8jO4ahwCA==","signature_status":"signed_v1","signed_at":"2026-07-05T07:15:18.910650Z","signed_message":"canonical_sha256_bytes"},"source_id":"2311.12818","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:189f5008846e38b6cda9444916cf3ecec773a8ed4b1c5badeb6c70b0068df07d","sha256:c35d9f721151607e9bb389f061d5e589bff01a4bf675cd2f456910e92a0d471a"],"state_sha256":"1e644d6756c7088ad9af306c277af42c52d3eaec7329cba69b9ccc62a9487869"}
