Abstract

https://speedysplat.github.io 2.6M Gaussians 25.39 PSNR 184.87 FPS GT 3DGS Ours 0.26M Gaussians 25.34 PSNR 1148.77 FPS Figure 1. We reduce the number of Gaussians by over 90%, only marginally decrease PSNR, and accelerate rendering speed by 6.2× in the Tanks & Temples truck scene when compared to 3D Gaussian Splatting (3D-GS). Additionally, we speed up training time by 1.38×.
