TensoRF: Tensorial Radiance FieldsAbstract We present a novel approach to model and reconstruct radiance fields. Unlike NeRF that uses pure MLPs, we consider the full volume field as a 4D tensor and propose to factorize the tensor into multiple compact low-rank tensor components for efficient scene modeling. We model a scene (left) as a tensorial radiance field (right) using a set of vectors and matrices that describe scene appear
