with angle 1 to 270 (the viewshed is written but incorrect).
Interestingly, it works with angle 0 to 270.
Your PR [https://github.com/OSGeo/grass/pull/180 #180] works for me. I
tested in the NC dataset with
{{{
g.region -p rast=elev_state_500m
r.viewshed in=elev_state_500m out=viewshed
coord=637942.9512846764,188095.68718268772 obs=100 direction_range=0,270
r.viewshed in=elev_state_500m out=viewshed
coord=637942.9512846764,188095.68718268772 obs=100 direction_range=1,270
r.viewshed in=elev_state_500m out=viewshed
coord=637942.9512846764,188095.68718268772 obs=100 direction_range=270,0
r.viewshed in=elev_state_500m out=viewshed
coord=637942.9512846764,188095.68718268772 obs=100 direction_range=270,1
}}}
and the results seem to be correct.
Can you provide an example where your PR does not work?
