The Takeaway
Existing Gaussian Splatting methods suffer from severe artifacts when rendering at resolutions different from their training data. This band-limiting approach allows for 3D representations that remain visually stable and accurate across a 4x scale range without retraining.
From the abstract
Feed-forward 3D Gaussian Splatting (FF-3DGS) emerges as a fast and robust solution for sparse-view 3D reconstruction and novel view synthesis (NVS). However, existing FF-3DGS methods are built on incorrect screen-space dilation filters, causing severe rendering artifacts when rendering at out-of-distribution sampling rates. We firstly propose an FF-3DGS model, called AA-Splat, to enable robust anti-aliased rendering at any resolution. AA-Splat utilizes an opacity-balanced band-limiting (OBBL) de
