# v0.9.6 — Manual Admission: 9 New Methods (872 → 881)

**Date:** 2026-10-07
**Scope:** Manual admission of 9 new arXiv-verified 3DGS methods; no historical entries rewritten.

## Summary

Manual admission of 9 new methods verified via arXiv API against the R9 admission protocol
(method name must be self-stated in the paper's title/abstract). The admission includes
**Speedy-Splat** (CVPR 2025, by Hanson et al. including Geng Lin) and **8** recent September 2026
papers spanning acceleration, pruning, pose-free, NBV, sparse-view, robustness, large-scale,
optimization, and compression categories.

- Library: **872 → 881** methods (+9, +1.0%), 23 categories unchanged.
- All data carriers (`methods.json` / `CSV` / `methods.html` / `abstracts.js`) and the reference
  doc (`references/3dgs-methods-overview.md`, "Newly Added Methods (October 2026)") re-verified at
  **881**; name sets compared entry by entry via `scripts/crosscheck_carriers.py`.
- No method name was fabricated; the library's "every entry arXiv-verifiable" guarantee holds.
- `categories.json` counts re-computed from `methods.json` (fixes prior stale counts).

## Method Highlights

### Speedy-Splat (CVPR 2025) — Acceleration
**Authors:** Alex Hanson, Allen Tu, Geng Lin, Vasu Singla, Matthias Zwicker, Tom Goldstein (UMD)

Identifies and addresses two key inefficiencies in 3D-GS rendering:
1. **SnugBox** — precise axis-aligned bounding box from alpha-thresholded ellipse extent (1.82× speedup, lossless)
2. **AccuTile** — exact Gaussian-tile intersection by iterating ellipse-boundary intersections (1.99× speedup, lossless)
3. **Soft Pruning** — reparameterized Hessian pruning score (36× less storage than PUP 3D-GS), 80% pruning during densification (3.14× speedup)
4. **Hard Pruning** — 30% pruning every 3000 iters post-densification (6.71× speedup, 10.6× compression, 1.47× training speedup)

Evaluated on Mip-NeRF 360, Tanks & Temples, Deep Blending. PSNR 27.55 → 26.94 (-0.61 dB) at 10.6× compression.

### Other 8 methods
- **AESplat**: Pose-free feed-forward 3DGS, decoupled SH; +0.8 dB over NAS3R, +1.1 dB over DepthSplat on RealEstate10K
- **AGILE-GS**: SE(3) anchor-guided NBV; selection latency reduced 1-2 orders of magnitude
- **OC-GS**: Object-centric GS for irregular turntable; 12/8/6 views → 21.26/19.36/15.83 dB
- **ClearGS**: Reliability-aware view allocation + render-guided in-video restoration; SOTA on GS2E/GSOTM
- **ChronoFuseGS**: Multi-temporal Gaussian fusion with per-splat persistence; PG 2026
- **TangoGS**: Capture-derived learning allowance + training-quality guided density control; 48% fewer Gaussians
- **RRTO-CF3DGS**: Reliability-regulated trajectory optimization for COLMAP-free 3DGS; SOTA on T&T and CO3D-V2
- **Observation-Gram**: Per-Gaussian observation Gram matrix for SH compression; +0.49 dB over Compressed3D

## Rejected (0)

No candidates were rejected in this manual admission. All 9 papers were pre-verified via arXiv API
and confirmed to self-state their method names in the title or abstract (R9 protocol).

**Note:** Laplacian Frequency Hierarchies (2609.03334, Pacific Graphics 2026) was found to already
exist in the library and was not re-admitted.

## Carrier sync

Count-caliber files bumped to **881 methods / 15 skills** and version **v0.9.6**:
- `data/methods.json` (881 methods, count field updated)
- `data/categories.json` (counts re-computed from methods.json, fixes prior stale counts)
- `3dgs-methods-overview.csv` (881 rows)
- `docs/methods.html` (881 entries)
- `docs/abstracts.js` (9 new abstracts with EN + CN)
- `references/3dgs-methods-overview.md` (new "October 7, 2026" section)
- `package.json` (version 0.9.6, description 881 methods)
- `CLAUDE.md` (881 methods throughout)
- `README.md` / `README_CN.md` (new "What's New (Oct 2026)" entry, 881 count)
- `docs/index.html` (881 count)
- `docs/app-common.js` (881 count in zh + en i18n)

## Notes

- **R9 caveat for RRTO-CF3DGS**: title has no short acronym; method name taken from the code
  repository `github.com/Zijian1026/RRTO-CF3DGS`. The abstract uses "our framework" without a
  short name. Admitted on the basis of the self-stated code repository identifier.
- **categories.json fix**: prior `categories.json` counts were stale (e.g., Acceleration showed 13
  while methods.json had 22). This update re-computes all counts from methods.json, restoring
  consistency across all carriers.
- Speedy-Splat (CVPR 2025) is admitted by explicit user request despite being a 2025 paper; all
  other 8 admissions are September 2026 arXiv releases post-dating the v0.9.5 daily scan.
