# 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

| ----------- | ------------------------------------------------------------------ | --------- |
| `MODEL`     | The patched TripoSplat model with live preview functionality added | MODEL     |
