PreviewPointCloud - ComfyUI Built-in Node Documentation

The Preview Point Cloud node allows you to view a 3D point cloud file within the ComfyUI interface. It saves the point cloud to a temporary file and displays it in a 3D preview window, passing through the model data and viewport settings for further processing.
