h having a test point at its centroid with an irradiance reading.
So, shoudn't the total radiation energy for this surface be calculated as the sum of the radiation energy for patch A (3*2=6kwh) and that for patch B (5*1=5kwh) which is 11kwh?
The result for the current summation method used in Ladybug is (3+5)*(2*1)=24kWh.
As far as I understand, irradiance is an "intensity" variable, so, we need to multiply it by area to get the value of the absolute amount of radiation energy for a surface.
Please kindly comment.

Hello! In this tutorial, we are going over how to "twist" a 3 dimensional shape using Grasshopper. The precedent I used was the Cayan Tower in Dubai. Link to...
Hello,
I would like to know about how to orient an object to another one with 3 points in grasshopper as we normally do in rhino by simply picking 3 points.
Examples attached.
Thanks

she means to offset... we need to do a tower with 50 plane faces one above the other, but they need to be randomly moved in the xy plane in a range of 0 to 3 units...
ke very easy parts of Jewelry, like for sample:
1) Cutters
2) Prongs
3) Heads
Then, we have another that copies, scales and orients these parts to a Pave.
And the last part, is to make few definitions for making all kind of rings... But, using Generative Modeling. In other words, different than Matrix or RhinoGOLD, they do not have this.
Hope it helps some...
Today, I may make a video for the Cutters and Orient, Scale and Remap, see them on www.GJD3D.com and then, you will see the WHOLE idea...
Last, I want to teach this, and as a PLUS, give all 30 GH definitions to the students, that is like 900 US$ just for the definitions! :-)
Say hello to your friends in Aplicraf ok…
s: so if you have a gazillion of points you have a threshold of Math.Pow (gazillion, 4) loops > yikes ^ yikes.
BTW 2:
On the other hand ... clustering "structured" data (some call this as a "topological sort") is 10000 times faster than doing it in chaotic collections (like the random points on N BrepFaces etc).
Reason? Well ... a mesh (or brep) is a mini RDBMS (kinda) with regard "relations" (connectivity) between the 3 basic "classes of objects": vertices, edges and faces (or BrepFaces if we inquire a brep). This means that we can have 3*3 = 9 possible connectivity trees (see SandBox that makes some of them but it doesn't work on invalid [LOL] meshes).
So in this case of yours with that "drilled" mesh and approaching the problem the reverse engineering way ... the clustering "rule" is simple: if the normal angle of a given meshFace VS any other search meshFace normal is within some tolerance (say 1 to 5 degrees or some other domain) > consider the faces as coplanar > get the search meshFace index in a cluster (a branch in some Tree, that is), remove it from the search list and go find some other or initiate a new cluster. This means 2 nested search loops VS 4 (a colossal difference).
The good news are that when we search similar stuff we have connectivity info on hand (neighbor faces, that is) and this makes a colossal difference in the processing time required.
So if this first pass is finished we get points sampled into tree branches > meaning equivalent planes fitted to these > the rest are history (with a variety of ways). …
can you send me a screenshot of the extra flyout?
do you have two grasshopper folder or did you, as we recommend it ,just dragged the grasshopper.rhp into the rhino 5 canvas?
