DA3GeometryToMesh - ComfyUI Built-in Node Documentation - ComfyUI

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
