Mip-NeRF 360 Ours GT w/o diffusionw/o background Ours GT PDF: Point Diffusion Implicit Function for Large-scale Scene Neural Representation

The BlendedMVS [7] dataset is a large-scale synthetic dataset for multi-view 6 stereo containing 113 scenes, which can be further divided into large-scale outdoor scenes part and 7 small-scale objects part according to the scene scale. Since current large-scene NeRF methods are 8 one model per scene, to save computational resources and time, we select the first five scenes of the 9 large-scale outdoor scenes part and compare with Mip-NeRF 360 [2], which is the optimal baseline 10 on the representative subset of OMMO dataset [3] as shown in our manuscript, see Tab. 4 and Figure 1 .
