### Glare from a high-reflective tower facade

I would like to examine which parts of a high-reflective tower facade contribute to glare in rooms across the tower. Some patches of the facade reflect sunlight at different times of the day and cause glare in different rooms across the tower. Can I assign these patches (surfaces) a light source using the rcontrib or possibly using mkillumor what would be the best practice to do this?

Update based on Greg's answer below: Ok, first of all, I use Honeybee to export my Geometry and create rad files here is the list of the files I get out of Honeybee:

A sky file (climateBasedSky@_12_17@1500.sky). A geometry file (glaretest.rad). Material file material_glaretest.rad). Points (glaretest_0.pts)

I split my tower facade into two pieces (panels) so it's easier to test the workflow (later, I will need to split it into 180 panels)

I assigned each panel a mirror material with different names as follows:

void mirror small_patch
0
0
3 1 1 1

void mirror large_patch
0
0
3 1 1 1


The generated points were created co-planar with the window surface

I ran the following command:

oconv -r 2048 -f material_glaretest.rad climateBasedSky@_12_17@1500.sky glaretest.rad  > glaretest_IMG.oct


Then:

rpict -i -t 10 -vth -vp -17.000000000003862 10.000000000003865 1.2000000000762194  -vd 1.0 0.0 0.0  -vu 0.0 0.0 1.0  -vh 180.000 -vv 180.000 -vs 0.000 -vl 0.000 -x 64 -y 64  -af glaretest_IMG.amb  -ps 8 -pt 0.15 -pj 0.6 -dj 0 -ds 0.5 -dt 0.5 -dc 0.25 -dr 32 -dp 64 -st 0.2 -ab 7 -ad 512 -as 128 -ar 16 -aa 0.250 -lr 4 -lw 0.000 -av 0 0 0  glaretest_IMG.oct > glaretest_IMG.unf


Then this command to calculate the contribution of the large_patch and small_patch:

rcontrib < glaretest_0.pts -m small_patch -m large_patch -I+ -ab 12 -ad 50000 -lw 2e-5 glaretest_IMG.oct > test.vmx


I get a .vmx file with a 6 column matrix and "n" rows (n=the number of the test points). Is this workflow correct? if so how would I translate the numbers in the matrix, although I converted the numbers from ASCII format to numbers I didn't understand what these numbers meant, the numbers are integers between 5 to 101.

To create a pair of images should I use this command:

vwrays −ff −x 1024 −y 1024 −vf  glaretest_IMG.unf| rcontrib −ffc ‘vwrays −d −x 1024 −y 1024 −vf glaretest_IMG.unf‘ @render.opt −o c_%s.hdr −m small_patch −m large_patch glaretest_IMG.oct

Then this command to calculate the contribution of the large_patch and small_patch:

rcontrib < glaretest_0.pts -m small_patch -m large_patch -I+ -ab 12 -ad 50000 -lw 2e-5 glaretest_IMG.oct > test.vmx


I get a .vmx file with a 6 column matrix and "n" rows (n=the number of the test points). Is this workflow correct? if so how would I translate the numbers in the matrix, although I converted the numbers from ASCII format to numbers I didn't understand what these numbers meant, the numbers are integers between 5 to 101.

To create a pair of images should I use this command:command?

vwrays −ff −x 1024 −y 1024 −vf  glaretest_IMG.unf| rcontrib −ffc ‘vwrays −d −x 1024 −y 1024 −vf glaretest_IMG.unf‘ @render.opt −o c_%s.hdr −m small_patch −m large_patch glaretest_IMG.oct


If this is the righ comand, what would be the input in place of "@render.opt"?

When I spilt the facade into 180 panels, can I put their material names into a text file then refence the file when calling rcontrib?rcontrib? (I read somewhere that this is possible)

One last question, can I assign the facade panels their real material instead of mirror. Their material should be this:

void BRTDfunc  reflective_Glz
10  rR_bronze rG_bronze rB_bronze  0.21*tR_bronze   0.237*tG_bronze   0.209*tB_bronze   0 0 0   window.cal

### Glare from a high-reflective tower facade

I would like to examine which parts of a high-reflective tower facade contribute to glare in rooms across the tower. Some patches of the facade reflect sunlight at different times of the day and cause glare in different rooms across the tower. Can I assign these patches (surfaces) a light source using the rcontrib or possibly using mkillumor what would be the best practice to do this?

Update based on Greg's answer below: Ok, first of all, I use Honeybee to export my Geometry and create rad files, here is the list of the files I get out of Honeybee:

A sky file (climateBasedSky@_12_17@1500.sky). A geometry file (glaretest.rad). Material file (material_glaretest.rad). Points (glaretest_0.pts)

I split my tower facade into two pieces (panels) so it's easier to test the workflow (later, I will need to split it into 180 panels)

I assigned each panel a mirror material with different names as follows:

void mirror small_patch
0
0
3 1 1 1

void mirror large_patch
0
0
3 1 1 1


The generated points were created co-planar with the window surface surface, is this the right area to place my points for the rcontrib command (I'm more interested in visual comfort than in illuminance on a work plane)

I ran the following command:
