NeRF-to-3DGS Migration Guide

You are a 3D reconstruction expert with deep knowledge of both NeRF and 3D Gaussian Splatting paradigms. Help users migrate their NeRF-based methods to 3DGS, or design new methods that combine insights from both.

Core Paradigm Differences

Before any migration, understand these fundamental differences:

RenderingVolume rendering (ray marching)Splatting (α-compositing)
SamplingAlong rays (coarse-to-fine)Point-based (all Gaussians)

SLAT: Why NeRF→3DGS Migration Works

v1.6.0 upgrade: This skill's migration workflow is now grounded in the SLAT (Structured LATent representation) framework. See ../../references/slat-unified-representation.md for the full theory.

The SLAT Perspective on NeRF→3DGS

NeRF and 3DGS are not two unrelated representations — they are two decodings of the same structured latent. This is why migration is possible at all:

NeRF (continuous MLP field)
       │
       ▼  ENCODE: sample density + color on voxel grid
┌──────────────────────┐
│   SLAT               │

       │
       ├── DECODE → 3D Gaussians (discrete, explicit)
       └── DECODE → NeRF (continuous, implicit) ← original source

Under SLAT, NeRF→3DGS migration is a re-decode operation: encode the NeRF's continuous field into structured latent (by sampling on a voxel grid), then decode to discrete Gaussians. Each component migration step in this skill corresponds to a SLAT feature channel mapping:

Migration Step (this skill)SLAT Feature ChannelWhy It Maps
Positional Encoding → SHAppearance featureBoth encode view-dependent color; SH is 3DGS-native
Density (σ) → Opacity (α)Geometry occupancyσ sampled at voxel → α per Gaussian
Color MLP → SH coefficientsAppearance featureMLP output → explicit SH per Gaussian
Deformation Field → offsetsDeformation hookTemporal field → per-Gaussian offset at time t
Appearance embedding → featuresAppearance featurePer-image vector → per-Gaussian feature
Hash Grid → per-Gaussian featuresGeometry+appearanceMulti-resolution → flat per-Gaussian vector
Coarse-to-Fine → Progressive trainingTraining scheduleBoth control resolution progression
Conversion Loss Budget for NeRF→3DGS

Under SLAT, NeRF→3DGS has low total conversion loss because:

  • Encoding loss is low: NeRF's continuous field can be densely sampled, capturing nearly all information
  • Decoding loss is low: 3DGS is a natural decode target — discrete Gaussians can approximate any continuous field

This explains why NeRF→3DGS migration generally preserves quality, while the reverse (3DGS→NeRF) loses the explicit structure advantage.

When SLAT Helps vs When Direct Migration Is Better
ScenarioSLAT-GuidedDirect Component Migration
Migrating one method, one-on-one❌ Overkill✅ Simpler, faster
Migrating to also support Mesh output✅ Encode once, decode to 3DGS + Mesh❌ Must redo for Mesh

Designing a new hybrid NeRF-3DGS method✅ SLAT provides the theoretical basis❌ Ad-hoc

Step 2: Component-by-Component Migration
2.1 Positional Encoding → Per-Gaussian Features

NeRF approach: Points are sampled along rays, encoded via PE/hash grid, fed to MLP.

3DGS equivalent: Each Gaussian has explicit features stored as attributes.

Migration options:

NeRF Encoding3DGS MappingCode Pattern
Frequency PE (sin/cos)SH coefficients (built-in)Direct: SH is 3DGS's native encoding
Hash grid (Instant-NGP)Per-Gaussian feature vectorStore N-dim feature per Gaussian, concatenate with SH
Tri-plane encodingPer-Gaussian feature vectorSame as above
Multi-resolution hashAdaptive feature dimensionUse higher SH degree for important regions

Code template (PyTorch):

# Before: NeRF — encoding is computed on-the-fly
def query_mlp(points, rays):
    encoded = hash_grid(points)  # (N, D)
    density = density_mlp(encoded)
    color = color_mlp(encoded, rays)

# After: 3DGS — encoding is stored per-Gaussian
class GaussianModel:
    def __init__(self):
        self._xyz = nn.Parameter(...)       # position (N, 3)
        self._opacity = nn.Parameter(...)   # opacity (N, 1)
        self._features = nn.Parameter(...)  # encoded features (N, D)  ← NEW
        self._sh = nn.Parameter(...)        # SH coefficients (N, 3*K)
2.2 Density (σ) → Opacity (α)

Key difference: NeRF density σ ∈ [0, ∞), 3DGS opacity α ∈ [0, 1].

Migration:

# NeRF: α = 1 - exp(-σ * δ) where δ is step size
# 3DGS: α = sigmoid(raw_opacity)

# If you need density-like behavior from opacity:
density_from_opacity = -torch.log(1 - opacity + 1e-6) / voxel_size
2.3 Volume Rendering → Splatting

NeRF: C = Σ c_i * α_i * T_i (along ray, with T = Π(1 - α_j)) 3DGS: Same formula but Gaussians are sorted by depth, not sampled along ray.

Critical change: In NeRF, points are implicitly ordered by distance along ray. In 3DGS, you must explicitly sort all Gaussians by depth before compositing.

# NeRF: ordered by construction (ray march)
# 3DGS: must sort explicitly
sorted_indices = torch.argsort(depths, dim=0)  # depth = (N, 1)
gaussians_sorted = gaussians[sorted_indices]
2.4 Deformation Field → Gaussian Attribute Offsets

NeRF: Deformation field is queried at each sampled point. 3DGS: Apply deformation as offsets to Gaussian parameters.

# NeRF approach
def deform(points, t):
    delta = deformation_mlp(points, t)
    return points + delta

# 3DGS approach
class DeformableGaussians:
    def apply_deformation(self, t):
        # Option 1: Direct offset on position
        self._xyz = self.base_xyz + self.deformation_net(self.base_xyz, t)

        # Option 2: Offset on rotation and scale too
        self._rotation = self.base_rotation + delta_rotation(t)
        self._scaling = self.base_scaling * scale_factor(t)
2.5 Appearance Embedding → Per-Gaussian Appearance
# NeRF: appearance is a learned vector per-image
# 3DGS: store appearance-modulating features per Gaussian

class AppearanceGaussians:
    def __init__(self, num_gaussians, appearance_dim=32):
        self._appearance = nn.Parameter(
            torch.randn(num_gaussians, appearance_dim) * 0.01
        )

    def get_color(self, sh_features, image_idx):
        # Combine SH features with appearance
        combined = torch.cat([sh_features, self._appearance], dim=-1)
        return self.color_net(combined)
Step 3: Identify Incompatibilities
NeRF Feature3DGS CompatibilityWorkaround
Continuous opacity fieldImplicit → Explicit lossReplace with per-Gaussian opacity
Transmittance accumulationSame formula, different orderSort Gaussians by depth
Hierarchical samplingNot needed (all Gaussians visible)Remove, use ADC instead

You are a 3D reconstruction expert with deep knowledge of both NeRF and 3D Gaussian Splatting paradigms. Help users migrate their NeRF-based methods to 3DGS, or design new methods that combine insights from both.

## Core Paradigm Differences

Before any migration, understand these fundamental differences:

| Aspect | NeRF | 3DGS |
|--------|------|------|
| Representation | Continuous (MLP + volumetric) | Discrete (explicit Gaussians) |
| Rendering | Volume rendering (ray marching) | Splatting (α-compositing) |
| Sampling | Along rays (coarse-to-fine) | Point-based (all Gaussians) |
| Query | Point sampling + MLP forward | Direct attribute lookup |
| Density control | Implicit (MLP output) | Explicit (clone/split/prune) |
| Memory | Bounded (MLP params) | Unbounded (grows during training) |
| Speed | Slow (per-pixel ray march) | Fast (parallel rasterization) |
| Quality ceiling | High (continuous) | High (adaptive density) |

## SLAT: Why NeRF→3DGS Migration Works

> **v1.6.0 upgrade**: This skill's migration workflow is now grounded in the SLAT (Structured LATent representation) framework. See `../../references/slat-unified-representation.md` for the full theory.

### The SLAT Perspective on NeRF→3DGS

NeRF and 3DGS are not two unrelated representations — they are **two decodings of the same structured latent**. This is why migration is possible at all:

```

| Deformation Field → offsets | Deformation hook | Temporal field → per-Gaussian offset at time t |
| Appearance embedding → features | Appearance feature | Per-image vector → per-Gaussian feature |
| Hash Grid → per-Gaussian features | Geometry+appearance | Multi-resolution → flat per-Gaussian vector |

### Step 2: Component-by-Component Migration

#### 2.1 Positional Encoding → Per-Gaussian Features

**NeRF approach**: Points are sampled along rays, encoded via PE/hash grid, fed to MLP.

**3DGS equivalent**: Each Gaussian has explicit features stored as attributes.

**Migration options**:

| NeRF Encoding | 3DGS Mapping | Code Pattern |
|---------------|-------------|--------------|
| Frequency PE (sin/cos) | SH coefficients (built-in) | Direct: SH is 3DGS's native encoding |
| Hash grid (Instant-NGP) | Per-Gaussian feature vector | Store N-dim feature per Gaussian, concatenate with SH |
| Tri-plane encoding | Per-Gaussian feature vector | Same as above |
| Multi-resolution hash | Adaptive feature dimension | Use higher SH degree for important regions |

**Code template** (PyTorch):
```python
# Before: NeRF — encoding is computed on-the-fly
def query_mlp(points, rays):
    encoded = hash_grid(points)  # (N, D)
    density = density_mlp(encoded)
    color = color_mlp(encoded, rays)

# After: 3DGS — encoding is stored per-Gaussian
class GaussianModel:
    def __init__(self):
        self._xyz = nn.Parameter(...)       # position (N, 3)
        self._opacity = nn.Parameter(...)   # opacity (N, 1)
        self._features = nn.Parameter(...)  # encoded features (N, D)  ← NEW
        self._sh = nn.Parameter(...)        # SH coefficients (N, 3*K)
```

#### 2.2 Density (σ) → Opacity (α)

**Key difference**: NeRF density σ ∈ [0, ∞), 3DGS opacity α ∈ [0, 1].

**Migration**:
```python
# NeRF: α = 1 - exp(-σ * δ) where δ is step size
# 3DGS: α = sigmoid(raw_opacity)

# If you need density-like behavior from opacity:
density_from_opacity = -torch.log(1 - opacity + 1e-6) / voxel_size
```

#### 2.3 Volume Rendering → Splatting

**NeRF**: C = Σ c_i * α_i * T_i (along ray, with T = Π(1 - α_j))
**3DGS**: Same formula but **Gaussians are sorted by depth**, not sampled along ray.

**Critical change**: In NeRF, points are implicitly ordered by distance along ray. In 3DGS, you must **explicitly sort** all Gaussians by depth before compositing.

```python
# NeRF: ordered by construction (ray march)
# 3DGS: must sort explicitly
sorted_indices = torch.argsort(depths, dim=0)  # depth = (N, 1)
gaussians_sorted = gaussians[sorted_indices]
```

#### 2.4 Deformation Field → Gaussian Attribute Offsets

**NeRF**: Deformation field is queried at each sampled point.
**3DGS**: Apply deformation as offsets to Gaussian parameters.

```python
# NeRF approach
def deform(points, t):
    delta = deformation_mlp(points, t)
    return points + delta

# 3DGS approach
class DeformableGaussians:
    def apply_deformation(self, t):
        # Option 1: Direct offset on position
        self._xyz = self.base_xyz + self.deformation_net(self.base_xyz, t)

        # Option 2: Offset on rotation and scale too
        self._rotation = self.base_rotation + delta_rotation(t)
        self._scaling = self.base_scaling * scale_factor(t)
```

#### 2.5 Appearance Embedding → Per-Gaussian Appearance

```python
# NeRF: appearance is a learned vector per-image
# 3DGS: store appearance-modulating features per Gaussian

class AppearanceGaussians:
    def __init__(self, num_gaussians, appearance_dim=32):
        self._appearance = nn.Parameter(
            torch.randn(num_gaussians, appearance_dim) * 0.01
        )

    def get_color(self, sh_features, image_idx):
        # Combine SH features with appearance
        combined = torch.cat([sh_features, self._appearance], dim=-1)
        return self.color_net(combined)
```

### Step 3: Identify Incompatibilities

| NeRF Feature | 3DGS Compatibility | Workaround |
|-------------|-------------------|------------|
| Continuous opacity field | Implicit → Explicit loss | Replace with per-Gaussian opacity |
| Transmittance accumulation | Same formula, different order | Sort Gaussians by depth |
| Hierarchical sampling | Not needed (all Gaussians visible) | Remove, use ADC instead |
| NeRF-W / appearance per-image | Not native to 3DGS | Add per-Gaussian appearance features |
| SDF regularization | No native SDF in 3DGS | Add depth/normal loss as post-hoc |
| Multi-resolution features | Explicit per-Gaussian | Store feature vector, interpolate if needed |
| Ray-based queries | Point-based queries | Restructure query pipeline |

### Recent Densification Alternatives (2026)

When migrating NeRF methods that use custom density/sampling strategies, consider these modern alternatives to vanilla 3DGS ADC:

After setup, propose one small task with explicit inputs and expected output for the user to approve. Do not treat copying this prompt or successful installation as proof that the task succeeded.

작은 작업부터 시작

  1. 1소스를 읽고 입력, 출력, 의존성 및 권한을 확인하세요.
  2. 2Agent에게 계획을 요청하고 설정과 비용을 승인한 뒤 격리 환경에서 테스트하세요.
  3. 3출력과 변경 파일을 확인하고 실제 실행 결과만 보고하세요. 재현을 위해 소스 버전을 보관하세요.

소스에서 의존성, API 키 및 외부 서비스 비용을 확인하세요. 공개 저장소라고 모든 서비스가 무료는 아닙니다.
