SteadySplats: Resampling of Low-Variance Gaussians for High-Fidelity Stochastic Rendering

SteadySplats introduces a method to reduce high‑frequency noise in stochastic rendering of 3D Gaussian Splatting models. The approach combines a history‑based spatial resampling scheme for faster image convergence, temporal importance resampling for camera‑movement coherence, and a color regularizer during training to lower variance along view rays. The resulting Vulkan‑based renderer achieves a 13 dB PSNR improvement over prior stochastic methods at one sample per pixel and converges quickly to a low‑error sorted 3DGS representation.

ReSplat: Learning Recurrent Gaussian Splatting

ReSplat introduces a recurrent Gaussian splatting model that iteratively refines 3D Gaussians using the rendering error as a feedback signal, avoiding explicit gradient computation. The method starts from a compact reconstruction in a subsampled space, producing far fewer Gaussians than prior per‑pixel models, which reduces computational cost. Experiments on multiple datasets, view counts, and resolutions show state‑of‑the‑art performance with faster rendering speeds.
