How 4D Gaussian Splatting Works: From Canonical Gaussians to Deformation Fields

The article explains how 4D Gaussian Splatting avoids memory explosion in dynamic scene rendering by keeping a single set of canonical Gaussians, using a factor‑decomposed deformation field built from six 2D HexPlane grids, and training with carefully staged loss functions and learning‑rate schedules.
