Episode notes
Olli Prefers PostShot Locally
- Olli primarily uses PostShot for Gaussian splatting due to its local PC operation and flexibility.
- Other platforms like Luma AI have moved focus away from Gaussian splatting, limiting their current usefulness.
Optimize and Clean Gaussian Inputs
- Optimize your input images by removing blurry, shaky, or overly repetitive photos before training.
- Clean irrelevant background splats and floating artifacts after training to reduce file size.
Compress By Managing Harmonics
- Use software like SuperSplat to selectively remove spherical harmonics layers to reduce file sizes.
- Removing all spherical harmonics compresses files drastically but may flatten surface appearance.
