What I figured yesterday is that the increase in radiation because of the reflective facade for the 'worst' month is only about 2-3 kWh/m2 as your looking at a value of 80 without and 82-83 kWh/m2 with reflection.
So my assumption is that the glare factor will play a much bigger role instead of intensity of the sun, looking at comfortable levels. So I'm looking in this as well. It's very cool to play around with these plugins and see the outcome. I'll keep you guys posted.
@ Claudio, that was exactly my problem as well. I presented a direct sunlight hour analysis, to show the increase in direct sunlight hours because of the mirrored facade and at what times of the day the reflections occurred. But it is hard to asses if this is 'bad' or 'good'. The restaurant in question receives more or less 130 direct sunlight hours 'naturally' in the worst month and because of the reflection the result was 161 direct sunlight hours, but the client was like okay..... and is this a problem? So we decided to look at sun intensity but I didn't want to fall into the trap of in the end presenting kWh/m2 and having the same problem not knowing if this is 'comfortable' or 'annoying' etc. Good luck with your study, I'll post my findings
Thanks again guys…

I think i'm about 80% there. It may not be the most elegant procedure, but it appears to be working. I am having some slight problems.
1. I'm having trouble extracting the edge curve on one side of my mesh
a. I used a mesh plane intersection to trim my site mesh, and the resultant curve extends beyond the limit of my mesh
b. I identified the intersection point, but GH is not shattering on that intersection point. instead it happens at a point further down the polyline
2. I'm can't join my curves. If i bake them, they join into a closed curve.... GH join curves is not behaving. i've had some success joining two segments, but i can seem to get all 4 side wall curves to join.
if anybody could offer some advice, i'd be very appreciative. also, i'd like some recommendations for ways to streamline this definition. I'm sure that there are more creative ways to manage this data, and i'd love to about them. thanks - CSDG

use an attractor curve to adjust curves that are being lofted to create a "wavey" surface. I've attached a picture to show the end result. Right now i create all the curves and then loft them together to create a surface which could then have a rib definition applied to it, and it works, my problem is that this project is for a 80' section of wall with ribs that would be a few inches apart, so that is a ton of curves i have to change everytime i want to adjust the overall shape. So is it possible to have an attractor curve that instead of adjusting the spacing of shapes in plane with the curve, would create high points or low points perpendicular to the curve? Hopefully that makes some sense, i'm having trouble finding the words to explain it, the attached pictures should help.
Any advice on how to do this would be great. I hate being that guy but this project came up last minute and it seemed like something the Grasshopper help save a ton of time in as far as adjustments go.
Thanks,
Kyle

h kangaroo and have found one project that illustrates my idea exactly...
https://vimeo.com/88002087
So far my best attempt has been to use a gridded surface in which the lines of the grid are springs, with a rest length at 80% of their initial length. (call this grid A) This is to simulate as if the material has been stretched 120% of its resting dimensions.
I have been trying to anchor the springs to a secondary grid (Grid B, curves that will be deposited onto the material) at the points of intersection with grid A.
I am not sure if this is the best approach, maybe soapfilm would be better? although i require the boundary (grid B) to adapt also...
Any advice or attempts to explain how Taichi Kuma has done this in his video would be greatly appreciated.
Thanks…
A: Who created it? / Copyright?
B: Anyone have a larger resolution copy of this image (or a vector so I can do a large resize).
Long and short - I'm an artist and I'd like to make a quilt out of that image. I need a decent resolution copy of it so I can do a huge resize and get a 76" x 80" crop out of it. I've tried resizing it in Photoshop, but by the time it's large enough, the quality has dropped below what is usable for my needs.
Thanks in advance! I totally understand I'm relying on the kindness of strangers here. (Also if this is inappropriate to post - please delete. Thank you)

e analysis) into a grasshopper script that will effect the way objects are placed, or formed? I have been all over the internet trying to find answers and had little luck so I decided to think of an example and post it to the forum. I have looked into functions, path mappers, data trees and many other components.
Say my site had 2 buildings, one that was built in 1918 (B1) and one that was built in 1920 (B2). But B2 was demolished in 2009 and B1 still exists (2011). Can a simple script be created to model this? I have had a go but my most successful attemt still fails, I can get a true statement when the the number 1920 and above is reached but I cannot get it to also show a false reading for when the number 2009 is reached.
If someone could help me out on this and show (tell) me how this could be used as a variable to create design/the placement of objects, it would be MUCH appreciated.
Cheers

use for some typical reasons why solar access can be important:
Solar Access for Passive Solar Heating - The conditional statement should request sun vectors for any hours below the balance point of the building (the temperature at which the building starts requiring additional heating). For residences, this can be as high as 18C and for commercial/retail buildings with high internal heat gains, this can be as low as 10C. 16C is around what you might find for some residences with better insulation and is probably the reason why that is chosen in the file.
Solar Access for Outdoor Thermal Comfort - The conditional statement should request sun vectors for any hours below the lower limit of outdoor comfort (UTCI uses 9C for this lower limit).
Solar Access for Health of Plants/Trees in a Park/Garden - This is a bit of the opposite of the other metrics since you want hours of the warmer season. In this case, I usually use solar radiation as the annualHourlyData with the conditional statement and I request hours that are above a certain radiation level (where the plants are benefiting the most). I then use an analysisPeriod to get rid of any months of the year when the trees don't have leaves on them.
Hope this helps,

edefined), keeping it perpendicular to line 1. Now I get O2, the origin of line 2.
To get the direction of line 2, I cross-multiply the vector O1-A1 and the vector A1-O2, and then rotate the cross-product around the axis A1-O2, the rotation angle is ALPHA.
Then I evaluate A2, keeping O2-A2 = O1-A1. From A2 I draw A2-O3, the distance of which equals to A1-O2. To get the direction of A2-O3, I rotate the direction of A1-O2 around the axis O2-A2, the rotation angle is BETA.
Then repeat the process to get line 3 and line 4. From line 4 I can get the position of O5 (O5 is the point P in my previous post), and I want O5 to be the same as O1 (or as close as possible).
The two parameters are ALPHA and BETA. Quite a complex process, hope the explanation is clear enough. Basically I just want to calibrate ALPHA and BETA so that O5 can be close enough to O1.…
