The first sponsored challenge is to create a parametric version of Buckminster Fuller’s Dymaxion House.
It would be AWESOME to see it done in Grasshopper! And.. You can win a pretty sweep HP desktop plotter. The deadline is this Friday.
Hope to see you on the site and look for some new GH and RhinoScript videos coming soon.
Thanks,
Dave…

start (if there is a better one I would appreciate a hint), but I thought I populate a rectangle with points, interconnect the points to later let the borders of the rectangle attract each other.
I have 4 rectangles: A, B, C and D.
On each I have 20 points (A0-A19, B0-19, etc.)
Now I want to connect each point to all the points on the other rectangles, e.g. point A0 with all the (60) points on rectangle B, C, D.
I saw the discussions about the topic sorting lists (e.g. flipping), but I didn't see them fitting on this problem, or I don't know how to abstract them for me.
Also this is a problem I am having with another definition, so if someone could help me with that list stuff, I think I could use it furthermore.
But if there is a better solution to the rectangle organisation (tessellation), I am open for that.
regards,
Max

tting-edge results at the interface of geometry processing and architectural design. Scientific chairs of the conference are Lars Hesselgren, Shrikant Sharma, and Johannes Wallner. Keynote speakers are: Pierre Alliez, INRIA Sophia-Antipolis Philip Ball, Physicist and science writer Chuck Hoberman, Hoberman Associates Jan Knippers, Knippers Helbig Advanced Engineering
We are happy to announce that public lectures will be held by Toyo Ito and Mutsuro Sasaki. The organization is cordially inviting you to contribute a paper or a workshop, or simply to visit. More details concerning registration and submission can be found on the conference web page at http://aag12.architecturalgeometry.at/. The submission deadline has recently been extended.
This conference receives funding from the ECs Seventh Framework Programme under grant agreement number 230520. Thanks to this funding we are able to cover the registration fees and support the travel expenses of 20 young participants. Places will be distributed among those who submit a poster, paper or workshop proposal.…
per space. In the upper right corner you draw another dot, and you write "1, 1" next to it. You now have 2 points defined in paper space (uv space).
Ok, lay down the pencil and pick up the paper. You'll notice that the two points have just moved through world-space. They were very close to the desk, but now they are hovering above it. The coordinates you wrote down on the paper or the other hand are still valid.
No matter what you do to this piece of paper; crumple it, fold it, take it on a plane to South Africa, those two points remain fixed in paper space.
A surface is always a rectangle in Rhino. It may be deformed, it may have holes cut into it, but in the end it's always a rectangle, just like your piece of paper. UV coordinates are points that are defined in Surface UV space. They consist of only two numbers, because a surface has no thickness. At any point in time, you can translate these UV points into World XYZ points using what is called a surface evaluator. Where these XYZ points end up depends entirely on the *shape*, *size* and *location* of the surface.

Surface uv-space (and Curve t-space) are vital when dealing with nurbs geometry. If you do not understand the concept of parameter space, you will have a lot of problems because many components in Grasshopper use these coordinates.

raries folder, seems that you need plankton.gha.
Unlock, place in folder, restart rhino+gh...
That's all.
To use it... in a basic way:
Input 0. Plug geometry.
Input 1. Set target resolution, actually it refers to the mesh edge length.
Optional input 2 and 3. Sets anchors (as points or curves) for the remeshing not escape of these parts.
Input penultimate. Number of iterations. Here are two ways, the living form, you set a low value (as 5 or 10) of iterations and plug in a timer component (that allows you to see the remesh process); or just add the total number of iterations (I generally use 80, but its relative).
The last input, set false to turn it on, true to turn it off.
For advanced configuration, trial and error, or see the code on Pikers's github.…
ьютера за требуемое время не получен нужный отклик, или было разорвано уже установленное соединение из-за неверного отклика уже подключенного компьютера 178.63.48.217:80This component requires OSM data to be downloaded from openstreetmap.org. It has just failed to do that. Try the following two fixes: 1) Sometimes due to large number of requests, the component fails to download the OSM data even if openstreetmap.org website and their services are up and running.In this case, wait a couple of seconds and try rerunning the component. 2) Try lowering the "radius_" input.

- 100.
After that, I want to separate it into 5 different lists in spesific thickness.
in this case of 0-100 so it would be :
1. if the distance 0 - 20 then the thickness is 5
2. if the distance 21 - 40 then the thickness is 10
3. if the distance 41 - 60 then the thickness is 15
4. if the distance 61 - 80 then the thickness is 20
5. if the distance 81 - 100 then the thickness is 25
But, the problem is the list of distance isn't static between 0-100. It could be 5 - 250 / 3.5-175/etc.....
Could you help me how to make the expression?? Is this possible if I make one expression?
thank you.
Z.
nb: distance and thickness hasn't mathematical relation.…

a with high impact and far from easy to customize.
I'm trying to use and understand the Dragonfly_Boundary_Layer_Parameters block, whose parameter setting seems to have a huge impact on the UHI results. In particular the nightBndLayerHeight parameter. First of all, the default value in the doc (800m) does not correspond to the one in the code (80m). After having set it at 800m with a constant block, the RunUWG component doesn't run until the end, giving the following error message : "Error in ReferenceSite/VerticalDifussionModel (line 141) / Error in xml_new (line 394)". It seems that some combinaisons of nightBndLayerHeight / referenceHeight work (80 / 100 or 800 / 800) and others not (800 / 100).
Does that comes from the model preparation? Or the UWG algorithm itself?
I tried to find for some "tables" linking these weather layers to the different urban typologies... without success. Would have someone ref / paper recommandations?
Kind regards,
Rom

rep' to type 'System.Collections.Generic.IEnumerable`1[Rhino.Geometry.Brep]'. (line: 86)
This basically translates to: "I wanted a collection of Breps and you've given me a single brep". You'll need to put your cone and boundingbox into a collection. Easiest is to make an inline array:
Dim result As Brep() = Brep.CreateBooleanIntersection( _
New Brep() {cone}, _
New Brep() {boundingbox}, _
0.001)
I concur it should probably work on individual breps as well, I'll add those overloads to RhinoCommon.
-----------------------------
Dim volume As Double = rhino.geometry.VolumeMassProperties.Compute(result(0))
This is wrong. VolumeMassProperties.Compute() does not return a single number. It returns a new instance of the VolumeMassProperties class, which contains the volume, but also the error, the centroids, the moments of inertia and so on and so forth.
Dim vp As VolumeMassProperties = VolumeMassProperties.Compute(result(0))
A = vp.Volume
