# Extract Mesh from Splat

This node converts a 3D Gaussian splat into a colored mesh surface. It works by rasterizing the gaussians onto a density grid, extracting an iso-surface at a chosen density level, and then applying optional smoothing and cleanup to produce a clean, colored triangle mesh.

## Inputs

| Parameter       | Description                                                                                                                                                                                                                                 | Data Type | Required | Range                 |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | --------------------- |
| `splat`         | The input gaussian splat to convert to a mesh                                                                                                                                                                                               | SPLAT     | Yes      | -                     |
| `resolution`    | Density-grid resolution along the longest axis. Higher values produce finer surface detail but require more VRAM and processing time (grows with resolution^3). Default: 384                                                                | INT       | Yes      | 64 - 768 (step 16)    |
| `kernel`        | Maximum splat half-width in voxels. Each gaussian is rasterized over a window sized to its own 3-sigma, capped at this value. Small surfels stay cheap while large ones aren't truncated. Raise if sparse splats leave gaps. Default: 5     | INT       | Yes      | 1 - 8                 |
| `smooth`        | Taubin mesh-smoothing iterations. Smooths the surface without shrinking it (volume-preserving), unlike blurring the density. 0 means no smoothing. Default: 0                                                                               | INT       | Yes      | 0 - 60                |
| `level`         | Iso-surface level. Auto-picked by Otsu thresholding; this value biases the auto-pick (1.0 = auto, lower values produce fatter/more-connected surfaces, higher values produce thinner/tighter surfaces). Default: 0.4                        | FLOAT     | Yes      | 0.0 - 2.0 (step 0.01) |
| `min_component` | Drops connected components smaller than this many vertices. Removes detached floater blobs and the inner shell of double walls. 0 keeps all components. Default: 500                                                                        | INT       | Yes      | 0 - 100000 (step 50)  |
| `min_opacity`   | Ignores gaussians fainter than this value before meshing. Default: 0.02                                                                                                                                                                     | FLOAT     | Yes      | 0.0 - 1.0 (step 0.01) |
| `color_sharpen` | Crisps up the vertex texture. 1.0 gives physically-correct blend; higher values bias each voxel's color toward its dominant gaussian instead of averaging neighbors (de-smears the texture). Affects color only, not geometry. Default: 2.0 | FLOAT     | Yes      | 1.0 - 8.0 (step 0.5)  |

## Outputs

| Output Name | Description                                                                                   | Data Type |
| ----------- | --------------------------------------------------------------------------------------------- | --------- |
| `mesh`      | The extracted colored mesh with unlit rendering (emissive-like) to match the splat appearance | MESH      |
