5-phase method with sky vector

Hi all,

I am trying to the rendering part of the 5-phase method with sky vectors
instead of the sky matrices. I'd appreciate it if anyone could help me with
writing the gensky scripts.

Best,
Leyla

Hi Leyla,
You need to use the -5 option in gendaymtx, which isn't an option for
genskyvec at the moment. I'd suggest using a single-timestep sky matrix.

you could make a *.wea file like this:
place Oakland Metropolitan Arpt_USA
latitude 37.72
longitude 122.22
time_zone 120
site_elevation 2.0
weather_data_file_units 1
1 1 12.000 655 129

Than it's:
$ gendaymtx -of skies/OakLand.wea > matrices/OakLand.smx
$ gendaymtx -of -d skies/OakLand.wea > matrices/OakLand_direct.smx
$ gendaymtx -5 -d -m 6 -of skies/OakLand.wea >
matrices/OakLand_direct_m6.smx

And change -n 8760 to -n 1:
$ dctimestep -n 1 -if viewpics/back_%03d.hdr \ bsdf/fullwindow.xml
matrices/daylightmatrix.dmx matrices/OakLand.smx > hourlypics/back.hdr

I think that works...
