# DA3GeometryToMesh - ComfyUI Built-in Node Documentation

> This node converts a DA3GEOMETRY packet into a 3D mesh by unprojecting the depth map and triangulating the resulting point cloud.

This node converts a DA3\_GEOMETRY packet into a 3D mesh by unprojecting the depth map and triangulating the resulting point cloud. It processes a single image from a batch and produces a textured or untextured mesh suitable for 3D rendering.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `da3_geometry` | The DA3\_GEOMETRY packet containing depth map, optional confidence map, optional sky map, and source image | DA3\_GEOMETRY | Yes | - |
| `batch_index` | Which image of a batch to convert. Per-image vertex counts differ so batches cannot be stacked (default: 0). Must be less than the batch size of the input geometry, otherwise an error is raised | INT | Yes | 0 to 4096 |
| `decimation` | Vertex stride. 1 = full resolution, 2 = half, etc. (default: 1) | INT | Yes | 1 to 8 |
| `discontinuity_threshold` | Drop triangles whose 3x3 depth span exceeds this fraction. 0 = off (default: 0.04) | FLOAT | Yes | 0.0 to 1.0 |
| `confidence_threshold` | Exclude pixels whose per-image normalised confidence is below this value. 0 = keep all, 1 = keep only the single most confident pixel. Used when the geometry has a confidence map (Small/Base models) (default: 0.1) | FLOAT | Yes | 0.0 to 1.0 |
| `use_sky_mask` | Exclude sky-probability pixels (sky >= 0.5) from the mesh. Used when the geometry has a sky map (Mono/Metric models) (default: True) | BOOLEAN | Yes | True or False |
| `texture` | Use the source image as a base color texture (default: True) | BOOLEAN | Yes | True or False |

Pixels with non-finite, zero, or negative depth values are always excluded from the mesh. An error is raised if the resulting mesh is empty; the error message suggests raising `discontinuity_threshold`, lowering `confidence_threshold`, or disabling `use_sky_mask`.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `MESH` | A triangulated 3D mesh with vertices, faces, UV coordinates, and optional texture | MESH |
