# TripoSplat Sampling Preview

This node patches a TripoSplat model so that when used with the standard KSampler node, a live preview of the decoded gaussian splat is shown at each sampling step. It works by wrapping the sampler's callback to decode the model's output into a preview image after every step.

## Inputs

| Parameter | Description | Data Type | Required | Range |
|-----------|-------------|-----------|----------|-------|
| `model` | The TripoSplat model to patch for live preview | MODEL | Yes | |
| `vae` | TripoSplat VAE decoder | VAE | Yes | |
| `octree_level` | Octree depth for the preview decode (lower = cheaper/coarser). Default: 5 | INT | No | 2 to 8 |
| `num_gaussians` | Number of gaussians to produce for the preview (rounded to a multiple of 32). Default: 16384 | INT | No | 1024 to 262144 (step: 32) |
| `yaw` | Preview camera yaw in degrees. Default: 90.0 | FLOAT | No | -360.0 to 360.0 (step: 1.0) |
| `pitch` | Preview camera pitch in degrees. Default: 15.0 | FLOAT | No | -89.0 to 89.0 (step: 1.0) |
| `point_size` | Maximum splat radius in pixels. Each gaussian is sized from its scale and capped here; lower = finer/pointier, higher = chunkier. Default: 3 | INT | No | 1 to 16 |

## Outputs

| Output Name | Description | Data Type |
|-------------|-------------|-----------|
| `MODEL` | The patched TripoSplat model with live preview functionality added | MODEL |
