# 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)**:
   ```bash
   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](https://github.com/PozzettiAndrea/ComfyUI-Sharp/discussions) or [Issue](https://github.com/PozzettiAndrea/ComfyUI-Sharp/issues). Very grateful for your help! 🙏

ComfyUI wrapper for [SHARP](https://arxiv.org/abs/2512.10685) by [Apple](https://github.com/apple/ml-sharp) - 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.
