# VAEDecodeTripoSplat

Decode a TripoSplat latent representation into a 3D gaussian splat. This node takes the sampled latent from a TripoSplat model and reconstructs it as a set of 3D gaussians, which can be adjusted in density by modifying the number of gaussians produced.

## Inputs

| Parameter       | Description                                                                                                                                                                                                                      | Data Type | Required | Range                     |
| --------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------- |
| `samples`       | The latent samples to decode                                                                                                                                                                                                     | LATENT    | Yes      | -                         |
| `vae`           | TripoSplat VAE decoder model                                                                                                                                                                                                     | VAE       | Yes      | -                         |
| `num_gaussians` | Number of gaussians to produce (rounded to a multiple of 32). 262144 matches the octree's point density; higher oversamples the same points (denser, but no new detail) and costs proportionally more VRAM/time. Default: 262144 | INT       | Yes      | 32 to 1048576 (step: 32)  |
| `seed`          | Seeds the octree point sampler (global RNG) for deterministic decodes. Default: 0                                                                                                                                                | INT       | Yes      | 0 to 18446744073709551615 |

**Note:** The `num_gaussians` value is automatically rounded to a multiple of the VAE decoder's gaussians-per-point setting. The actual number used may differ slightly from the input value.

## Outputs

| ----------- | ---------------------------------------------------------------------------------------------------------------------- | --------- |
| `splat`     | The decoded 3D gaussian splat containing positions, scales, rotations, opacities, and spherical harmonics coefficients | SPLAT     |
