for waves, that is done with a 'phase shift', add 2*pi/4 radians (for a 90 deg shift) to your sin curve, could also be done using cos instead of sin for an inherent 90 deg shift

This data is then mapped to the "glow" material that represents the celestial hemisphere...You can edit the climate based sky produced by Honeybee and enter your own values. The other option would be to just use gendaylit from DOS Prompt.…

(A -> AB, B -> BA) -> in result you get AB BA
n=3: ABBABAAB (A->AB;B->BA;B->BA;A->AB) result: AB BA BA AB
n=4: ABBABAABBAABABBA (etc. etc.)
