It reduces computational requirements by adapting the lattice on which the underlying differential equations are solved to most efficiently represent the solution. Particularly in astrophysics and cosmology such simulations now can capture spatial scales ten orders of magnitude apart and more. The irregular locations and extensions of the refined regions in the SAMR scheme and the fact that different resolution levels partially overlap, poses a challenge ","authors_text":"Ralf Kaehler, Tom Abel","cross_cats":["cs.GR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2012-12-13T21:00:02Z","title":"Single-Pass GPU-Raycasting for Structured Adaptive Mesh Refinement Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.3333","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":"sha256:71fddf19e259b820d79db3f58b27548e9d87cdcf33b02af3e2b43f9b7cd62ad5","target":"record","created_at":"2026-05-18T01:52:38Z","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":"0a7ca6ba5fb11234fcb838682ffebdbafa658c8666192d77c9418f05b98f4aca","cross_cats_sorted":["cs.GR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2012-12-13T21:00:02Z","title_canon_sha256":"a85951c17fa8f46f31109a8b22182ede518d521bfcdc1c8e401638f11b9c9142"},"schema_version":"1.0","source":{"id":"1212.3333","kind":"arxiv","version":1}},"canonical_sha256":"66a1df2642a6f79b776f7b1248c6d95e4d3f98a07d85abca3f6a503c559fd934","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"66a1df2642a6f79b776f7b1248c6d95e4d3f98a07d85abca3f6a503c559fd934","first_computed_at":"2026-05-18T01:52:38.505387Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:52:38.505387Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VNy514v8Ao5fMBbLgNHDaqJTL6sVP3Ht6saoERzH8Qr1hZ5lA/iwHukF3dW8qeF+1chMnbodLlM5O6PFfOflDg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:52:38.505998Z","signed_message":"canonical_sha256_bytes"},"source_id":"1212.3333","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:71fddf19e259b820d79db3f58b27548e9d87cdcf33b02af3e2b43f9b7cd62ad5","sha256:f30bb33acd71e07822d7eb09fc0d657bf6c4de12c776fdd26a8d3340a12605f8"],"state_sha256":"7585fc98ff4e588f9e32b921828255d3bfd61aee1d36901d6df1fbc62e58c9b9"}
