Researchers have introduced Grassmannian splatting, a novel method for rendering dynamic scenes. This technique utilizes rank-2 spacetime surfels, which are essentially 2D disks in spacetime that translate uniformly. Unlike previous methods that slice full-rank spacetime covariances, Grassmannian splatting conditions on time to produce rank-2 surfels, enabling a more efficient and closed-form motion model. The method demonstrated significantly faster training times on the MonoDyGauBench dataset, achieving speeds 4.9 to 5.6 times quicker than strong baselines while maintaining competitive visual quality.
