3D Avatar Creation
3D avatar is a technique, or art, that is crucial to many different fields, including film and gaming industry. However, creating a 3D avatar is not a trivial thing. To achieve fine details and photo-realistic appearance, it takes 3D artists 1 week to craft a 3D avatar with lengthy procedures.
In recent years, advancement of 3D reconstruction technology makes 3D avatar creation much easier. With reconstruction methods like Neural Radiance Field (NeRF) or 3D Gaussian Splatting (3DGS), a 3D avatar can be created within an hour with multi-view images or videos.
3D Gaussian Splatting (3DGS)
Among recent 3D reconstruction techniques, 3D Gaussian Splatting (3DGS) stands out with its great training efficiency and reconstruction quality. The central idea of 3DGS is to use numerous 3D gaussians a.k.a. colored ellipsoids in 3D space, to fit the geometry and appearance of any scene/object.
