le, update some of the components definitions (see attched: ctrl+E 1, 2 and 3. Not sure how it can be done automatically ... or more efficiently) and it will run it for you.
Those are the good news. But unfortunately i have also bad news:
Even though the WindowMaterial:Blind:EquivalentLayer is defined well, EnergyPlus is not taking it into account. This is a bug in E+ i think. In the Construction object the name of the Blind is highlighted, like it is missing. When you see what you can peek from the list you don't see the Blind name.
Moreover, i see that there is also another Object (Construction:WindowEquivalentLayer) that is supposed to be the one that "can model various mix of glazing and shading layers combination". But still when you define an object under this type you don't get the EquivalentLayerBlind either.
I'll try to report this on the helpdesk of E+.
Chris or Mostapha, are you aware of this issue with E+?

Hope it helps a bit.

ts of spheres, that are behind the camera, appear. This normally happens with weird lens length settings. The camera needs a 45° viewing angle and therefore might fall into this category. Maybe there is a good solution to get rid of this issue?
Issue #2: I have no clue how to run the screenshot calculation at the end of the solution. Normally I wanted to color the spheres in the video with the "Custom Preview" component, but they would not show up in the saved picture, since custom preview was calculated later than the screenshot component "Cubemap"
Issue #3: The calculation of an equirectangular image takes quite a while. ~4 seconds. Thats still good compared to the 9 seconds i had in the beginning. Multithreading through parallelizing could improve it even more, but it wouldn't work for me.
Especially ISSUE #2 is annoying and does not allow me to create a nice video. I would be glad if someone could assist me in this.
I actually tried already ExpirePreview or Solution, but maybe I used it the wrong way...
Best,

element have no arch. At 45 (= 90dB), the element should be convex. There is only one noise (only one measuring point), which is all 13 seconds re-measured.…
not sure which is the correct term).
So far I have done it pretty well out of an excel file and Grasshopper. I get the number of the cell and the rgb colour and a text (in my case a pantone). From this set up I can seed in Grasshopper different solutions and then decide which poster I want and from that point manually arrange the images but I wonder if I could create with some programing something like 30 or 40 different posters.
My .gh file is a bit messy even if it is simple. It takes the data from an excel sheet (I attach it), but to simplify it I have internalized the data into the .gh file so hope you can understand what I am trying to do.
So the idea is to get different images such as the ones shown in "Capture.jpg", but with the help of some code instead of manually organizing them.
I am trying with python, but I am not that good yet.
Any idea how could I do this or where should I ask for help?
Thanks in advance.

bk. He seems to do a pretty good job of explaining it.
One thing that makes complex numbers useful is that they simplify rotations in the plane. If a complex number z = x +i*y, then it can also be expressed as r*exp(i*theta), where r = the modulus sqrt(x^2 + y^2) and theta is the argument or angle with the x axis = arctan(y/x). That is what the grasshopper components above do; they extract this information. If you square the number, then you get a new number (r^2)*exp(2*i*theta), so the angle has been doubled.
In my example, the top right corner of the square was at point r=sqrt(2) and angle 45 degrees= pi/4. Squaring it brings it to the point r = (sqrt(2))^2 = 2 and angle 90 degrees = pi/4 *2 = pi/2. This is equivalent to the point x=0, y= 2 as you can see. Any point in the square whose angle is greater than 45 degrees, once doubled will be rotated into the second quadrant. The entire square sat in the first quadrant going from theta = 0 to 90 degrees. Squaring it takes it from 0 to 180 degrees, covering the first and second quadrants.
One other interesting thing about these kind of maps, they are "conformal", meaning that angles are preserved, so all of the 'squares' in the mapped image still have corners that meet at 90 degrees even though the squares themselves are distorted. This can be very useful.
Hope I haven't confused you further...
