The values in bold are then evaluated using the equations in the file perezlum.cal inside the RAYPATH directory in Radiance..
{ All-weather Angular Sky Luminance Distribution . Additional arguments required for calculation of skybright: A1 - diffus normalization A2 - ground brightness A3,A4,A5,A6,A7 - coefficients for the Perez model A8,A9,A10 - sun direction}skybright = wmean((Dz+1.01)^10, intersky, (Dz+1.01)^-10, A2 );wmean(a, x, b, y) = (a*x+b*y)/(a+b);intersky = if( (Dz-0.01), A1 * (1 + A3*Exp(A4/Dz) ) * ( 1 + A5*Exp(A6*gamma) + A7*cos(gamma)*cos(gamma) ), A1 * (1 + A3*Exp(A4/0.01) ) * ( 1 + A5*Exp(A6*gamma) + A7*cos(gamma)*cos(gamma) ) );
This data is then mapped to the "glow" material that represents the celestial hemisphere...You can edit the climate based sky produced by Honeybee and enter your own values. The other option would be to just use gendaylit from DOS Prompt.…
ider and a list item component to select a particular brep A or B or C, without selecting a particular breq inside each of them?
It seems the merge function will merge all the breqs inside each of the breps into one flattened list ...…
. The rules to dispatch the lines are the next:
I start with a list that alternate true/false; like that: true, false, true, false.
If the angles between those lines are greater than 89° I want to inverse the next part of the list:
True, False, True, False, True, False,...
become
True, False, [>89°] False, True, False, True, [>89°] True, False,...
I managed to create a true false list, to check for the greater than 89° angle, to separate the lines relatively to the angles, but I don't know how to inverse part of the list at certain index.
(In the picture, I have written 90° but it should be 89°, I check for greater than 89° and not equal to 90° because in the real rhino model, the lines won't be exactly orthogonal)
If you have another idea to to reach the same result, it's also okay, I tried to find rules to solve the problems, but I may have overlooked other solutions !
And if there is some part of the patch that are correct but there is easier solution, I would love to learn as I am still new to grasshopper.
Thanks for taking the time to read. :)

B0 ----> B1
B1 ----> B2
B2 ----> B3
B3 ----> B4
