Hi,
I am trying to use mkillum program, for window definition, from rad. If I understood well I should have 2 lines in .rif file: illum and mkillum.
-illum line
Should the file defined in this line contain both glazing material and surface definition or it can contain only one of them?
-mkillum line parameters:
-ab 2 - I suppose this is enough since the environment is clear (no obstructions)
-as and -ad can be the default for rtrace
-av - What exactly represents this -av value for mkillum? How could I compute it? Would the calculation be accurate if this is 0?
I am simulating simple room with a window on the South wall.
If I run compamb with rif file containing this mkillum, would it use the illum material data? I am asking this because in the book it said that rad would take care for all changes in illum files, but I am not sure if compamb would do that too.
I missed this e-mail, but I guess everyone else did, too....
The compamb script only computes the ambient value for rpict and rvu in rad, not mkillum. To get this, you are best off using the value given by gensky (assuming you're using gensky). For example, "gensky 8 10 15" spits out:
# gensky 8 10 15
# Local solar time: 14.77
# Solar altitude and azimuth: 47.3 70.4
# Ground ambient level: 18.1
(etc.)
For exterior calculations including mkillum, -av 18.1 18.1 18.1 would be appropriate.
As to the rest of the mkillum parameters, you have to think about how many bounces are important and set this yourself. Rad is not smart enough to figure it out (and neither am I unless I know your geometry).
