PET-NeuS: Positional Encoding Tri-Planes for Neural Surfaces

1 code implementation CVPR 2023 Yiqun Wang, Ivan Skorokhodov, Peter Wonka

The first component is to borrow the tri-plane representation from EG3D and represent signed distance fields as a mixture of tri-planes and MLPs instead of representing it with MLPs only.
