# Cut the distance in half, and then round it out so that it's

radii=dx[..., None] *2/np.sqrt(12)
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.

Use normalized direction vector or not?

AS you said: in
mipnerf/internal/datasets.py
Line 193 in 84c969e
BUT you use directions (not-norm) rather than viewdirs (unit-norm):
mipnerf/internal/datasets.py
Lines 187 to 195 in 84c969e
This is different,right?
mipnerf/internal/datasets.py
Lines 194 to 200 in 84c969e
