InstantSplat

An unofficial implementation of InstantSplat, an sparse-view, SfM-free framework for large-scale scene reconstruction method using Gaussian Splatting. Uses Rerun to visualize, Gradio for an interactive UI, and Pixi for a easy installation

Install and Run

Make sure you have the Pixi package manager installed

git clone https://github.com/pablovela5620/InstantSplat.git
cd InstantSplat
pixi run app

All commands can be listed using pixi task list

Hosted Demo

Demos can be found on huggingface spaces, local version is recommended to avoid GPU timeouts!
