non-rigid blending support

Creating a proxy function for non-rigid blending is not a difficult task. However, since there is no GUI support for this operation, one must pre-define a blending mapping, which can be quite complex.

In our case, we manually blend the original 3D model using Blender and compute the blending mapping from mesh. Nevertheless, this is just a temporary solution since most NeRF models do not have 3D ground truth. You can create one using marching-cube, but that goes against our idea of mesh-free.

Releasing this without nice GUI support is not ideal, which is why we have decided not to include it at the moment. However, there is no guarantee that we will/won't have GUI support in the future.
