GSDeformer: Direct, Real-time and Extensible Cage-based Deformation for 3D Gaussian Splatting

Understand

We present GSDeformer, a method that enables cage-based deformation on 3D Gaussian Splatting (3DGS).

• Our approach bridges cage-based deformation and 3DGS by using a proxy point-cloud representation.
• This point cloud is generated from 3D Gaussians, and deformations applied to the point cloud are translated into transformations on the 3D Gaussians.
• To handle potential bending caused by deformation, we incorporate a splitting process to approximate it.
