As of 2026-10-29, no independent citation, reproduction, or third-party evaluation of Hexels (arXiv:2610.37668) has been found, and the vault's single-source cap on it remains undischarged

A dedicated search for outside engagement with Hexels (Kaushik, Paul & Yuille, arXiv:2610.37668) — Semantic Scholar's citation API, general web search for citing papers or discussion, and the paper's own project page — located no independent citation, reproduction, or third-party evaluation. A direct Semantic Scholar Graph API query returned HTTP 429 (rate-limited) on two attempts, so no citation count could be read; general web search turned up no citing paper and no Hacker News, Reddit, or X/Twitter discussion. This is a search-negative, not a disconfirmation: the arXiv abstract page confirms the paper was "[Submitted on 27 Oct 2026]" with an "arXiv-issued DOI via DataCite (pending registration)" and no journal-ref — a two-day-old, unrefereed preprint, which is itself sufficient explanation for why no outside engagement has had time to appear.

The authors' own project page (honeycomb-surfels.github.io) does not change this: it repeats the paper's self-reported figures with no citation list and no independent evaluation of any kind. The one piece of released software it links, "Hexel Edge," is explicitly unrelated to checking the paper's benchmarks — a separate iPad/iPhone capture app marked "Under development" ("Hexel Edge Under development Capture. Train. Explore. On your iPad/iPhone. An open-source app for 3D reconstruction and novel-view synthesis with surface-aligned Hexels") — not a release of the core training/benchmark pipeline. No training code or benchmark harness for Hexels itself is linked from the page.

Per the vault's single-source concentration cap (sources.md), the cap on this preprint — already at three claim-notes (claim-hexels-replace-gaussian-kernel-with-hexagonal-support-and-linear-color-field-in-2dgs, claim-hexels-matched-memory-budget-psnr-gains-over-2dgs-and-triangle-splatting, claim-hexels-surface-reconstruction-chamfer-distance-and-f1-gains-over-2dgs) — remains undischarged; the matched-primitive-budget finding held back by the open question stays there. This search shares its shape with the vault's other recent young-preprint corroboration searches — claim-hu-2026-no-independent-corroboration-found-as-of-2026-10-24, claim-riker-2026-no-independent-source-same-author-admits-no-replication, and claim-no-independent-corroboration-pinheiro-ting-2026-babylonian-preprint-as-of-2026-10-28 — each a clean negative explained, at least in part, by the preprint's youth.
