PreviewGaussianSplat - ComfyUI Built-in Node Documentation

The PreviewGaussianSplat node allows you to preview a 3D gaussian splat file within the ComfyUI interface. It accepts a 3D model file in various gaussian splat formats and renders it in a 3D preview window, passing through the model data for further processing.

Inputs

Parameter	Description	Data Type	Required	Range
`model_3d`	A gaussian splat 3D file.	FILE3D	Yes	Supported formats: splat, ply, spz, ksplat
`model_3d_info`	Optional metadata information about the 3D model.	LOAD3DMODELINFO	No	-
`viewport_state`	The current state of the 3D viewport, including camera and model information.	LOAD3D	Yes	-
`camera_info`	Optional camera information for the preview.	LOAD3DCAMERA	No	-
`width`	The width of the preview render in pixels (default: 1024).	INT	Yes	1 to 4096
`height`	The height of the preview render in pixels (default: 1024).	INT	Yes	1 to 4096
