[!WARNING] Warning, uses experimental package comfy-env to attempt a one click isolated install. Will download and use pixi package manager.

ComfyUI-Sharp

Installation

Three options, in order of speed → reliability:

1. ComfyUI Manager (recommended) — search for Sharp in the Manager and click Install from the highest version displayed. If that doesn't work, try nightly.
2. Manager via Git URL — in ComfyUI Manager: "Install via Git URL" with https://github.com/PozzettiAndrea/ComfyUI-Sharp.git.
3. Manual (most reliable):

   cd ComfyUI/custom_nodes
   git clone https://github.com/PozzettiAndrea/ComfyUI-Sharp.git
   cd ComfyUI-Sharp
   pip install -r requirements.txt --upgrade
   python install.py
   

Please report any problems you hit during installation or use of my nodes — open a Discussion or Issue. Very grateful for your help! 🙏

ComfyUI wrapper for SHARP by Apple - monocular 3D Gaussian Splatting in under 1 second.

3 Example workflows.

Workflow 1: standard/user input focal length.

Workflow 2: focal length extraction from exif data.

Workflow 3: Panorama gaussians

Note: for PLY inference this model is good on its own, but for the Gaussian Viewer node, you're going to need to install this node as well! https://github.com/PozzettiAndrea/ComfyUI-GeometryPack

Model auto-downloads on first run. For offline use, place sharp_2572gikvuh.pt in ComfyUI/models/sharp/.

Nodes

• Load SHARP Model - (down)Load the SHARP model
• SHARP Predict - Generate 3D Gaussians from a single image
• Load Image with EXIF - Load image and auto-extract focal length from EXIF (35mm equivalent)

Images with EXIF data get focal length auto-calculated when using the Load Image with EXIF node.
