llff_config set ndc=True, why llff type data type ndc=True, but other datatype set ndc=False

To warp the unbounded forward-facing frustum to bounded bbox. You can find NeRF's supplementary material Sec.C for the detail about the NDC.

@sunset1995 thanks, do you try directvoxgo on real scene(not llff, nsvf, and so on) I take photo on common object like book，shoes(80 images per scene, 360 degree)，for better result，I use segmentation first to remove bg like nsvf , but render result is still worse
