Step 1: Analysis
Profile the 3DGS model before selecting compression methods:
| Attribute | FP32 Size | Typical Range | Sensitivity to Quantization |
|---|---|---|---|
| Position (μ) | 12B/Gaussian | Scene bounds | High — direct geometry impact |
| SH (degree 0–3) | 48B/Gaussian | [-1, 1] per coeff | Medium-High — visual quality driver |
| Opacity (α) | 4B/Gaussian | [0, 1] | Medium — pruning signal |
| Scale (s) | 12B/Gaussian | [1e-5, 1e2] | Medium — anisotropy sensitive |
| Rotation (q) | 16B/Gaussian | Unit quaternion | Low-Medium — can tolerate 8-bit |
Profiling checklist:
- Total Gaussian count N and file size S
- Target platform constraints (memory budget, bandwidth, GPU capability)
- Quality floor (minimum acceptable PSNR/SSIM)
- Required FPS threshold
- Whether dynamic (4DGS) or static scene
Step 2: Compression Strategy Selection
Decision tree by target platform:
Target Platform?
├── Web (WebGL/WebGPU)
│ ├── Bandwidth-limited → Pruning + VQ + Streaming (CAGS/HGS pipeline)
│ └── Compute-limited → Aggressive pruning + low SH degree + Flux-GS
├── Mobile (iOS/Android)
│ ├── Real-time required → Mobile-GS pipeline (depth-aware OIT + distillation + pruning)
│ └── Quality priority → MesonGS++ (mixed-precision, budget-controlled) + NanoGS merge
├── Desktop (GPU ≥ RTX 3060)
│ ├── Max quality → Light quantization only (8-10 bit, ContextGS entropy coding)
│ └── Large scene → Pruning + Streaming + HiGS hierarchical tiles
└── Edge / Embedded
├── FPGA targeted → SpqGS (hardware-friendly quantization) + Axis-Shared Accelerator
└── Low-power GPU → VEDAL pruning + 4-6 bit quantization + PocketGS on-device
Combined target table:
| Target | Typical Gaussian Budget | Bit-width Range | Streaming | Key Methods |
|---|---|---|---|---|
| Web | 100K–500K | 4–8 bit | Required | CAGS, StreamLoD-GS, Spark 2.0 |
| Mobile | 50K–200K | 4–8 bit | Optional | Mobile-GS, Flux-GS, PocketGS |
| Desktop | 500K–5M | 8–16 bit | For large scenes | MesonGS++, HiGS, gsplat |
| Edge/FPGA | 10K–100K | 2–6 bit | Required | SpqGS, VEDAL, GEMM-GS |
Step 3: Quantization
Method Selection
| Method | Type | Venue | Bit-width | Key Feature |
|---|---|---|---|---|
| MesonGS++ | Mixed-precision (post-training) | arXiv 2026 | 4–16 bit per attribute | 0-1 ILP hyperparameter search, 34x compression |
| GETA-3DGS | Joint pruning + quantization | arXiv 2026 | 4–8 bit heterogeneous | Render-aware saliency, QADG dependency graph |
| GSQ | Learned step size | CVPR 2025 | 4–8 bit | Group-wise quantization with learnable step |
| ContextGS | Context-model entropy coding | NeurIPS 2024 | 8–16 bit | Anchor-level context replaces uniform quant |
| SpqGS | Scalable parallel | CVPR 2025 | Hardware-friendly | Parallel bit allocation for FPGA/ASIC |
| SOG-GS | Channel-grouped | CVPR 2025 | Per-channel | Preserves inter-Gaussian correlations |
| ZipGS | Pruning + quant + entropy | CVPR 2025 | Variable | Volumetric entropy coding |
| GaussianCodec | Entropy-constrained | CVPR 2025 | Rate-distortion optimized | Learned codec with ECVQ |
| EAGLES | Quantized embeddings | ECCV 2024 | 8–16 bit | Coarse-to-fine training + pruning |
| TC-GS | Tri-plane representation | IEEE 2026 | Implicit via tri-plane | Replaces per-Gaussian SH with shared tri-plane |
Bit-width Selection Guide
| Attribute | 4–5 bit | 6–8 bit | 8–12 bit | 12–16 bit |
|---|---|---|---|---|
| Position | Edge only — visible artifacts | Mobile/Web acceptable | Desktop recommended | Lossless-range |
| SH (dc) | Not recommended | Edge/mobile | Desktop | High-fidelity |
| SH (rest) | Aggressive mobile | Mobile/Web | Desktop | Unnecessary |
| Opacity | Acceptable (post-sigmoid) | Recommended | Overkill | Overkill |
| Scale | Log-space 4-bit risky | Log-space 6–8 bit | Recommended | Overkill |
| Rotation | 8-bit often sufficient | Standard | Unnecessary | Overkill |
Rule of thumb: Position and SH dominate quality; allocate more bits there. Opacity and rotation tolerate aggressive quantization.
Step 4: Pruning

| Importance-based | Prune Wisely (DoG) | CVPR 2026 | 90% reduction | Minimal — DoG avoids false positives |
| Variational | VEDAL | arXiv 2026（venue 待核实） | 5.2x (0.31 dB drop) | Low — uncertainty-gated async pruning |
| Merge-based | NanoGS | arXiv 2026 | Training-free | Mass-preserving moment matching |
| Global+Local | LightGaussian | NeurIPS 2024 | 15x | SVD distillation compensates |

Commencer par une petite tâche
- 1Lisez la source et confirmez entrées, résultats, dépendances et permissions.
- 2Demandez un plan à l’agent. Approuvez la configuration et les coûts avant un test isolé.
- 3Vérifiez résultats et fichiers modifiés. Signalez uniquement ce qui a été exécuté et conservez la révision source.
Vérifiez les dépendances, clés API et frais externes dans la source. Un dépôt public ne rend pas tous les services gratuits.
