PreviewPointCloud - ComfyUI Built-in Node Documentation

The Preview Point Cloud node lets you view a 3D point cloud file directly in the ComfyUI interface without saving it to the ComfyUI output directory.

The Preview Point Cloud node lets you view a 3D point cloud file directly in the ComfyUI interface without saving it to the ComfyUI output directory. It saves the point cloud to a temporary location and displays it in a 3D preview window, while also passing the model data, camera information, and viewport state through for further processing.

Inputs

Parameter	Description	Data Type	Required	Range
model_3d	Point cloud file (.ply)	FILE3D	Yes	-
model_3d_info	Information about the 3D model	LOAD3DMODELINFO	No	-
viewport_state	The current viewport state	LOAD3D	Yes	-
camera_info	Camera information for the 3D view	LOAD3DCAMERA	No	-
width	Width of the preview window (default: 1024)	INT	Yes	1 to 4096
height	Height of the preview window (default: 1024)	INT	Yes	1 to 4096

Note: When camera_info or model_3d_info are not connected, the node falls back to the corresponding values stored in viewport_state. The point cloud file is saved to ComfyUI’s temporary directory and is not written to the output directory. This is an output node, so it is primarily used to display the preview result in the interface.

Outputs

Output Name	Description	Data Type
model_3d	The point cloud model data	FILE3D
model_3d_info	Information about the 3D model	LOAD3DMODELINFO
camera_info	Camera information for the 3D view	LOAD3DCAMERA
width	Width of the preview window	INT
height	Height of the preview window	INT
