AHA! Animating Human Avatars in Diverse Scenes with Gaussian Splatting Contributions: • We introduce the 3D Gaussian Splatting representation to the classical computer graphics problem of animating humans in 3D environments. • We demonstrate that our framework can be used for geometry-consistent free viewpoint rendering of monocular videos edited with new animated humans. • We introduce a novel Gaussian-aligned motion module for motion synthesis in scenes represented as 3D Gaussians. • We introduce a human scene Gaussian refinement optimization for the correct placement of human Gaussians in scenes represented using 3DGS, leading to better contact and interactions.
