Making the Waterfall in a Captured Splat Scene Actually Flow, Without Simulating Anything
Gaussian splatting assumes a static scene, and high-frequency motion like flowing water is intractable from casual capture. Make It Flow animates water in an existing static 3DGS scene with no dynamic capture and no physics simulation: 2D optical flow lifted to a consistent 3D motion field, applied to the Gaussian primitives as a seamless loop.
