This paper presents the differential equation that governs the shape of the specular surfaces, and illustrates how solutions can be constructed for different kinds of motion, lighting, host surface geometries, and fabrication constraints, leading to some novel forms of holography.","authors_text":"Matthew Brand","cross_cats":["cs.CG","physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GR","submitted_at":"2010-12-31T21:23:11Z","title":"Specular holography"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.0301","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":"sha256:6db1c6529a98989cdedecc3110d40cfb573bb00d914ce9ecef9b356bd8d34860","target":"record","created_at":"2026-05-18T01:22:44Z","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":"47c47ccc4bc8ab7fb2bbd52a3f51454b64eb87a346068709cdda376981821137","cross_cats_sorted":["cs.CG","physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GR","submitted_at":"2010-12-31T21:23:11Z","title_canon_sha256":"e2cde9e2e183095dbb1584d61920d2595dc3924c21f2ca17ab3eb3c966340937"},"schema_version":"1.0","source":{"id":"1101.0301","kind":"arxiv","version":1}},"canonical_sha256":"ccd80163be55399ad0fc88b0df50bc765e2d942c104999de27977144b1866522","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ccd80163be55399ad0fc88b0df50bc765e2d942c104999de27977144b1866522","first_computed_at":"2026-05-18T01:22:44.242037Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:22:44.242037Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ahiJVpREfqfuC2vChZslC/oAJlEQX1KpgFD+fZ2NW73A1jZyYAXTdRnqEvP1VWiutgTznS1wCKiNxXm5MPwnCw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:22:44.242715Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.0301","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6db1c6529a98989cdedecc3110d40cfb573bb00d914ce9ecef9b356bd8d34860","sha256:a96305ddb100012335f86faa69012ff1f2c9b6962c9d3afe8c19ea9517b5188b"],"state_sha256":"585c6954a756874526ecf117f082cb8fc777323753b612543125e2660d6908a0"}
