## Getting started
From the repository root, run `cd InfiniSplat_v2` for multi-view reconstruction or `cd InfiniSplat_v1` for single-image / LiDAR-guided reconstruction, then follow that version's installation guide. Install each version in its own Python environment; their dependencies and weights differ.

### Panorama to 3DGS (v2)
Reconstruct a 360° panorama with the included
`small_empty_house` example. Inspired by Enndee.
