About

What is InstantSplat?

InstantSplat is an official implementation of a sparse-view framework for large-scale 3D scene reconstruction using Gaussian Splatting. Developed by NVlabs, this tool supports 3D-GS, 2D-GS, and Mip-Splatting, allowing users to quickly generate detailed 3D environments from limited input. It is designed to be SfM-free, meaning it does not require Structure-from-Motion for camera pose estimation, significantly speeding up the reconstruction process. The repository provides comprehensive instructions for installation, including conda environment setup and Docker image usage, making it accessible for developers and researchers. InstantSplat is ideal for applications requiring rapid 3D model generation and free-view rendering, leveraging advanced techniques for efficient processing.
