I am working through re-simulating existing radiance models that were created in another programme and wanted to check if I am using the right method.
The files that I have received are 1 radiance model, 2 material files, and a range of bsdf files. (There are no window glow files for creating a view matrix or sky.rad files). The model has two windows, one faces north and one south and having these two windows is tripping me up a bit.
So overall, I have to create one sky matrix, two view matrices and two daylight matrices? Is this correct?
To make the view matrix I am using the command:
rcontrib -f klems_int.cal -bn Nkbins -fo -o results\photocells_%s.vmx -b kbinS -m windowsouth -b kbinN -m windownorth -I+ -ab 12 -ad 5000 -lw 2e-5 model2windows.oct < points.pts
in which %s should generate two files, but when I run it only generates one. Because of this I ran the command twice – one for the north window and one for the south window.
To make the daylight matrix for each window I used two commands to make each matrix:
rfluxmtx north.rad sky.rad material_detailed.rad materialsAliasesDetailed.rad radmodel.rad > north_dmx.dmx
rfluxmtx south.rad sky.rad material_detailed.rad materialsAliasesDetailed.rad radmodel.rad > south_dmx.dmx
Then I combine the matrices for the north window together and then south window together and then add together?
I would also like to know whether the window glow that needs to be inwards facing to create a view matrix can be in the same plane as the windows in the radiance model or if I can have it a couple millimetres in front of the radiance model window. It will mean I have two material directly on each other.
Any clarifications/comments would be very much appreciated.
