AS you said: in https://github.com/google/mipnerf/blob/84c969e0a623edd183b75693aed72a7e7c22902d/internal/datasets.py#L193
BUT you use directions (not-norm) rather than viewdirs （unit-norm）: https://github.com/google/mipnerf/blob/84c969e0a623edd183b75693aed72a7e7c22902d/internal/datasets.py#L187-L195 This is different,right? https://github.com/google/mipnerf/blob/84c969e0a623edd183b75693aed72a7e7c22902d/internal/datasets.py#L194-L200 If you use directions (not-norm) ,dx (or radii) will be the same for different pixel rays in the image . If you use viewdirs （unit-norm）, dx (or radii) will be smaller for pixel rays away from image center, and bigger for pixel rays around image center.
@jonbarron Help me please,thank you!
