Foundation Methods
| Method | Venue | Primitive | Opacity | Key Feature |
|---|---|---|---|---|
| 3DGS | SIGGRAPH'23 | 3D anisotropic | [0,1] sigmoid | Tile-based rasterization |
| Mip-Splatting | CVPR'24 (Best Student Paper) | 3D anisotropic + Mip | [0,1] | 3D smoothing + 2D Mip filter, alias-free |
| 2DGS | SIGGRAPH'24 | 2D disk | [0,1] | Better surface reconstruction |
| Scaffold-GS | ICCV'23 | Anchor+3D | [0,1] | Anchor-based scalability |
| Scaffold-GS+ | CVPR'24 | Anchor+3D | [0,1] | Progressive training |
| Softmax-GS | CVPR'26 (Findings) | 3D anisotropic | Softmax competition | Replaces α-compositing with learnable softmax; blend-vs-bound |
| LeGS | arXiv'26 | 3D anisotropic | RL-controlled | RL-based learnable density control replacing heuristics; O(N) reward |
| SNS | arXiv'26 (2605.15010) | Skew-Normal | [0,1] | Skew-Normal primitive replacing symmetric Gaussian kernels; continuous interpolation between symmetric Gaussian ↔ Half-Gaussian via learnable skewness |
Signed / Decomposed Methods
| Method | Opacity Range | Color Range | Mechanism |
|---|---|---|---|
| NegGS | [0, +∞) (non-negative) | ℝ (negative allowed) | Negative color + Diff-Gaussian |
| (Standard GS) | [0, 1] via sigmoid | [0, +∞) | Standard α-compositing |
Critical Distinction: Methods using "negative" concepts differ fundamentally:
- Signed opacity (α ∈ [-1,1]): Opacity α can be negative, rendering formula modified. The Gaussian primitive itself carries a sign. Better for sharp geometric boundaries.
- NegGS: Opacity remains non-negative, but color values can be negative. Uses Diff-Gaussian (subtraction of two Gaussians) to model ring/crescent structures.

Rules
- Be technically precise: Never oversimplify differences. If two methods differ in their opacity parameterization, explain exactly how.
- Quote metrics when available: Use actual numbers from papers, not estimates.
- Avoid bias: Present each method's strengths and weaknesses fairly.
- Context matters: A method that's worse on PSNR might be better for real-time. Always mention the use case.
- Flag uncertainty: If you don't have reliable data for a comparison dimension, say so explicitly.
