Deformation #50

Hi, how do controllable points guide 3D Gaussian deformation? Is there any constraint to achieve it? Thanks!

Hi, Thanks for discussing this. Briefly, the control points affect Gaussians using a learnable RBF determining the control weights. The method is a linear blending skinning (LBS) manner. Some constraints like ARAP regularization are used during training. For more details, please refer to our paper. : )
