Key points

  • An adaptive token expansion, or ATE, module automatically finds regions with large rendering error and adds Gaussians there.
  • Compared with dense baselines, it reduces the number of Gaussians by more than 5.7x while still reaching state-of-the-art quality.
  • It reconstructs 12 images at 512×960 in under 1 second and renders at 1,136 FPS.
  • Its 3D anchor-offset design decouples Gaussian placement from the input pixel grid.
  • Uncertainty predictions align well with the actual rendering errors, as shown visually.
