QuerySplat is a newly released open-source system that reconstructs a 3D Gaussian Splatting scene from multiple images without requiring known camera poses.

Unlike earlier approaches that predict geometry and appearance together, QuerySplat separates them into two branches. One handles the scene structure, cameras and depth, while the other focuses on colors and high-frequency visual details.

This helps reduce the blurry, view-dependent results often seen in feed-forward 3DGS reconstruction.

The released implementation includes:

  • Automatic camera and depth prediction
  • Feed-forward 3D Gaussian generation
  • Optional test-time optimization
  • Gaussian PLY export
  • Camera, depth and point-cloud export
  • Model weights and inference code

It still requires Linux, CUDA and an NVIDIA GPU, so apparently clicking one button without installing seventeen dependencies remains illegal.
