# SHARP — Single-Image 3D Gaussian View Synthesis

**Mirror of Apple's [SHARP](https://github.com/apple/ml-sharp) model weights**, converted to safetensors format for use with [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA).

## Model Description

SHARP predicts 3D Gaussian Splat (3DGS) parameters from a single photograph in under 1 second, then renders camera trajectory videos using [gsplat](https://github.com/nerfstudio-project/gsplat).

- **Input:** Single RGB image
- **Output:** 3D Gaussian splat representation → camera trajectory video or `.ply` export
- **Speed:** <1s prediction on GPU
- **Resolution:** 1536×1536 internal processing

## Usage in ComfyUI-FFMPEGA

1. Set `llm_model` to `none`
2. Set `no_llm_mode` to `sharp`
3. Connect an image to `image_a` or `image_path_a`
4. Run — the model will auto-download on first use

### Parameters

| Parameter | Default | Description |
|-----------|---------|-------------|
| `sharp_trajectory` | `rotate_forward` | Camera motion: rotate_forward, swipe, shake, rotate |
| `sharp_num_frames` | `60` | Number of video frames (10–300) |
| `sharp_max_disparity` | `0.08` | Lateral camera range |
| `sharp_max_zoom` | `0.15` | Zoom intensity |
| `sharp_save_ply` | `false` | Export .ply Gaussian splat file |
