In this paper, we present a manifold-based formulation of the glint normal distribution functions (NDF) that precisely captures the surface normal distributions over queried footprints. The manifold-based formulation transfers the integration for the glint NDF construction to a problem of mesh intersections. Compared to previous works that rely on complex numerical approximations, our integral solution is ex","authors_text":"Fujun Luan, Liwen Wu, Milo\\v{s} Ha\\v{s}an, Ravi Ramamoorthi","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.GR","submitted_at":"2025-05-13T21:53:58Z","title":"Position-Normal Manifold for Efficient Glint Rendering on High-Resolution Normal Maps"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.08985","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:fc2e48848bec2561dc964b4de78317fbee9e198d3b689b242b160bbe292b452e","target":"record","created_at":"2026-07-05T11:02:48Z","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":"89d37e2862bd8a6441c1d66829120ea143d9a847b8c7cf7469734f1f8a380fee","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.GR","submitted_at":"2025-05-13T21:53:58Z","title_canon_sha256":"57f68599d5f0285012fff8bcf1c124ae04313651ae2e8e708f89f7d6ec2eba95"},"schema_version":"1.0","source":{"id":"2505.08985","kind":"arxiv","version":1}},"canonical_sha256":"ddedf81fd3d42bf0e7fcbafc65c3ab647f9ca6ffa33d0932be612d3937c143a7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ddedf81fd3d42bf0e7fcbafc65c3ab647f9ca6ffa33d0932be612d3937c143a7","first_computed_at":"2026-07-05T11:02:48.307233Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:02:48.307233Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"O+YzOBP+/9qQfK0CqHo06dAMvT5E1nQ0+k8N68D2hGJ3W/2EsvOcamDzUfBg2VcQVkfDX6keGEzHJHvs23FtDw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:02:48.307777Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.08985","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fc2e48848bec2561dc964b4de78317fbee9e198d3b689b242b160bbe292b452e","sha256:c1d95617fbf29e2e47e52bd016a03f5d141117dd8452e33319360765426787e4"],"state_sha256":"206fa1868bcd65251bd5dac449fedc51876f18c0d71b0f7c1d5bb9fa9b705d50"}
