Highlight
Introduces a fully 3D evaluation and filtering pipeline for Gaussian Splatting that eliminates aliasing, projection distortions, and popping artifacts through adaptive 3D smoothing, stable view-space bounding, and efficient 3D culling, enabling real-time artifact-free rendering even for out-of-distribution views.
