e some questions.
I want to loop with a foreach loop trough a list of points do i have to make a list before or is it possible to use them coming in from a noed i set the access to list?
Also i dont understand why no plane is created. How do i need to feed the points in?
And why is c# expecting open parens in line 88 and 86?
Hope its not to much at once, probably i should try a few less steps to get the problems solved one by one, just hoped it would be easier and sometimes just a parentesis is missing or some format stuff, so maybe it is not so much i really cant say.
If anybody has the time and feels he wants to help it would be nice on the other hand i understand cause of the amount of chaotic questions.
Regards!…
" (idiomatic) and easy way of doing things.So here come some basic questions:
Is there a way to create custom components by grouping an existing sub-network together? I'm looking for a way to re-use parts of a program (something similar to subroutines), and to make the network look less cluttered. I found that it is possible to group components (ctrl-g), but this still displays them as separate blocks (too much clutter), and provides no way to re-use a sub-network in such a way that if it is modified in one place, all it's instances (all the places where it is re-used) also get modified.
Is there a component that does nothing, just passes a signal through? Suppose I need to connect block A to blocks B1, B2, B3 (all three get the same input). Then I change my mind, and I decide to connect block C to these three, not A. In this case it will be necessary to change three connections, not just one. I'm looking for an easy way to do this by a single rewiring, not three. (This came up in a practical situation).
Finally, a related question: is there a component that acts as a switch, so I can choose which signal it passes through out of a possible set of choices? For example, suppose that a set of objects can be coloured based on a number of different properties (size, positions, rotation, etc.) I'm looking for a way to switch between these very easily, without the need to do much rewiring.
Thank you in advance for any replies / useful comments, even general ones on how to easily structure a large Grasshopper program/network.…

here are my questions.
1. The difference in general attractor transition is that, i only want the points are moving toward x axis, so if i just have ONE curve to distinguish, which is'nt the problem to find points location are in the right of left side of curve, but if i have TWO or THREE curves need to be distinguished, that is totally confused to me!
2. The points near curve which moved too big, how can i make it more equal?
3. I hope all the points can stay in the square boundary.
If anyone can give me some hint, i would be very appreciate with that.
thanks a lot!!

bursts of calcium which interacts with a photoprotein to create flashes of light.
In the Pacific Canada Pavilion gallery at the Vancouver Aquarium, the public can excite origami jellies into creating beautiful patterns of colour and light using a touch screen controller.
When left alone, free from human intervention, the origami jellies instinctively react to each other. Random, generative displays of drifting coloured glow are triggered, not unlike jellies in their natural environment.
Jelly Swarm overhangs the gallery space. The soft, coloured light emitted by the jellies reflects on the aluminum surface. Viewed from below, the visual effect evokes looking up to the ocean's surface from undersea.
The installation features 94 origami jellies, folded in Tyvek. Each jelly contains its own RGB LED module. The 472ft² hanging surface was custom designed in 3D and fabricated from 6061T6 aluminum. Water jet cut and anodized on both sides, it comprises 154 generated triangles and 430 connector pieces.
Programed as self-contained objects capable of interacting with their closest neighbours, the Jelly LED modules are interrupted only by external intervention - the public engaging with the small display interface. Data is sent from an AIR app to each LED module via mbed wirelessly.

ake a modest notice about the two new Ladybug components, one of which creates a 3d terrain shading mask and another one which visualizes and exports horizon angles. A terrain shading mask is essentially a diagram which maps the silhouette of the surrounding terrain (hills, valleys, mountains, tree tops...) around the chosen location, and account for the shading losses from the terrain. It can be used as a context_ input in mountainous or higher latitude regions for any kind of sun related analysis: sunlight hours analysis, solar radiation analysis, view analysis, photovoltaics/solar water heating sunpath shading...
My home town is an example of the shading caused by the terrain. Here is how it looks from the tallest building in the town:
And the created terrain shading mask:
A mask for any land location up to 60 degrees North can be created:
There will also be a support for a few major cities above this limit.
Both Terrain shading mask and Horizon angles components can be downloaded from here. An example .gh file can be found in here.
Component will prompt the user to download and copy certain files in order to be able to run.
It was created with assistance from Dr. Bojan Savric. Support on various issues was further given by: Dr. Graham Dawson, Dr. Alec Bennett, Dr. Ulrich Deuschle, Andrew T. Young, LiMinlu, Jonathan de Ferranti, Michal Migurski, Christopher Crosby, Even Rouault, Tamas Szekeres, Izabela Spasic, Mostapha Sadeghipour Roudsari, Dragan Milenkovic, Chen Weiqing, Menno Deij-van Rijswijk and gis.stackexchange.com community.
I hope somebody might find the components useful.…
st between those two applications. But as soon as every frame is re-calculated I noticed that intersection function is very slow. It is actually so slow, that maximum number of polygons to play with is only 10 or less.
Could you help me to find a faster solution for my script?
calculation of intersection lines;
//////////////////////////////////////////////////////////////////////////////////////////
import ghpythonlib.components as ghcompimport rhinoscriptsyntax as rsdef ctr(crv): pts = ghcomp.Explode(crv)[1] pts = ghcomp.CullDuplicates(pts,0.001)[0] return ghcomp.Average(pts)pts = []lines = []ctr_c1 = ctr(C1)for crv in C2: if ctr(crv) != ctr_c1: int = ghcomp.CurveXCurve(C1, crv)[0] if int: [pts.append(x) for x in int] lines.append(rs.AddLine(int[0],int[1]))
/////////////////////////////////////////////////////////////////////////////////////////////
The overall description of the script:
a)Processing+ghowl is used for moving objects and physics
b)python script (slowest part) calculates intersection lines
c)intersected parts of polygons are rotated in 90 degrees.
I have attached grasshopper and processing files. (processing is not necessary to test the script)
Thank you in advance,
Pereas.
