a direct answer for you, in part because that statement suggests a complicated data tree indeed! And in part because I can't quite shake the question "Why?".
It's my nature to "think out of the box" and as you may have noticed, my answers in the other two threads related to this topic weren't quite what you asked for. The first question that comes to mind in this case is why look for the two closest trunks? Why not just the closest or why not "N" (all or all those within a given radius)?
The next question is why use a plane intersection at arbitrary height to get a point on each trunk for measuring distances between them?
So please bear with me as I explain how I've explored this problem so far, knowing I don't have an answer yet and, in fact, am not even sure that the question makes sense to me. ;)
First, I got tired of looking at these upside down "trees" so I flipped them right side up. I used 'Mirror' instead of 'Rotate' which might cause problems? But lets move on. I changed your preview colors so they wouldn't conflict with my 'Tree/List Viewer' defaults and to increase contrast a bit.
Then I skipped your methods for finding "Cluster 'B' and 'C'" and used 'Curve Proximity' between the trunks instead.
This is hard to convey with a static image but might make more sense interactively. There are two copies of 'Tree/List Viewer'; the second one ("slave" group) is driven by the set of sliders in the first one. As you move the 'path idx' slider, one of the trunks will be cyan in color, as set above. The others will be blue except for one that is yellow. As you move the 'list idx' slider, the yellow highlight will move among the blue trunks, showing the closest trunk at 'list idx' = 0 and the furthest at 'list idx' = 3 (five trunks total, one selected by 'path idx' and the other four by 'list idx'. The result is that for each trunk, we have all the other trunks sorted by distance.
That's all for now! There is a very simple way to connect the 'Twigs' instead of the 'Trunks' to 'Crv A' with interesting results, but it requires flattening the 'Twigs' so isn't as useful as we want.
The big question for me remains: what is the data/tree structure of the results you seek? From the statement I quoted above, it sounds like:
One branch per trunk.
For each trunk, one branch per twig? (or...?)
For each twig branch...? A list of distances to each of the other trunks? (or a list of the other trunks sorted by their distances from this twig?)
It sounds like a complicated mess, frankly. And again begs the question, why? What's the underlying goal beyond the objectives you have outlined so far?…

). It deals with the potential possibility to port GH into AEC fields (real-life AEC fields, nothing to do with academic thinking). The bad news are that the smart AEC sector is occupied solely by Bentley/GenComp – expect soon Revit/Dynamo as well (not to mention CATIA). The good news are that there’s millions of designers/engineers/industrial designers out there who could be interested for a 3rd alternative.
Intro: Well, in the old days (when men had mustache and muttonchops) AEC design performed in a nice top-to-bottom sequence (kinda like a vector) : the Big Man (aka The Brain) did some sketches (with crayons) and the rest (known as the “others”) struggled to make The Idea a reality. Today things are different, mind. Or they should be different. Or may be different. Or whatever. The big easy:For a zillion o reasons (AEC matures, PLM, cost, outsourcing, sustainable engineering…add several more) this vector like process of the past is like a Brown motion these days: Right down the moment that you (or your team) “sketch” The Big Idea … another team design simultaneously (i.e. in parallel) the components (parts) that compose the whole. This is the so called bottom-to-top design mentality. So the whole and the parts meet in some "middle point" instead the later being dictated by the former. In quite a few occasions parts dictate the whole (cost, cost and cost being the main reasons). The more a design is contemporary the more this bottom-to-top thing plays a critical role. Ignore it and have a very big time (sooner or later).The bad news:If you accept the above…well GH – at present phase - is not ready for contemporary AEC work. At.All.3 Main reasons for that:1.You can’t use parametric parts (i.e. nested blocks to speak Rhino language) into a given definition (in this case attached : truss nodes, connection flanges, mount plates, cable tensioners, planar glazing components, roof skin components…etc etc). This is obviously a Rhino domain.2.You can’t bake a given solution in such a way that the Rhino file is structured (i.e. assemblies of nested blocks). Or you can do it theoretically writing some VB/C code – but the core of the matter is that corresponding components are MIA. That means that you can’t export anything useful actually into established AEC oriented apps and/or established MCAD apps (for doing/calculating the parts for real-life production).3.The GH process can’t being interrupted. Imagine defining, say, a building “envelope” in GH and then …er…use Evolute tools in order to optimize things (say quad planarization and the likes). Then …continue in GH for more detailed work. Then design the parts as in 1 above. Then back to Evolute. Then back to GH.So…if anyone is interested I would be glad to start the mother of all debates and/or some kind of crusade (GH for President, that is).PS: This definition is a WIP thing – more refined stuff to follow (in particular a complex canopy tubes pre-stress system).
PS: Tree8 components are used sporadically.

al surface, but this is not happening with the edge mesh list!
In fact when I want to create mesh faces (the side mesh faces to close the boundaries surfaces) I can see (and I have tested/x2 checked within GH), that the corrispondent top edge and bottom edge of a determinated face are not coincident.
How can I assign a consistent index list to the top and bottom mesh edge list?
How the edge topology is assigned?
I post here the code, FYI, even I do not think that can help to find the problem.
And 2 screenshot to show you the problem.
double thickness = new double(); if (!DA.GetData(0, ref thickness)) return; Mesh baseMesh = new Mesh(); if (!DA.GetData(1, ref baseMesh)) return; List<Plane> localCSPlanes = new List<Plane>(); if (!DA.GetDataList<Plane> (2, localCSPlanes)) return; List<Mesh> solidMesh = new List<Mesh>(); List<Point3d> meshFaceCenterPlus = new List<Point3d>(); List<Point3d> meshFaceCenterMinus = new List<Point3d>(); List<Plane> localCSPlanesPlus = new List<Plane>(); List<Plane> localCSPlanesMinus = new List<Plane>(); List<Line> edgeMeshPlusLine = new List<Line>(); List<Line> edgeMeshMinusLine = new List<Line>(); Mesh offsetPlus = baseMesh.Offset(0.5*thickness, false); Mesh offsetMinus = baseMesh.Offset(-0.5 * thickness, false); Mesh recMesh = new Mesh(); solidMesh.Add(offsetPlus); solidMesh.Add(offsetMinus); //This for-cycle creates a index-consistent list of plus-offset mesh face center points and local coordinate system mesh planes. int nFcsPl = offsetPlus.Faces.Count; int nEdg = offsetPlus.TopologyEdges.Count; for (int i = 0; i <= nFcsPl - 1; i++) { meshFaceCenterPlus.Add(new Point3d(offsetPlus.Faces.GetFaceCenter(i))); localCSPlanesPlus.Add(new Plane(offsetPlus.Faces.GetFaceCenter(i), localCSPlanes[i].XAxis, localCSPlanes[i].YAxis)); } //This for-cycle creates a index-consistent list of minus-offset mesh face center points and local coordinate system mesh planes. int nFcsMn = offsetMinus.Faces.Count; int nEdgMn = offsetMinus.TopologyEdges.Count; for (int i = 0; i <= nFcsMn - 1; i++) { meshFaceCenterMinus.Add(new Point3d(offsetMinus.Faces.GetFaceCenter(i))); localCSPlanesMinus.Add(new Plane(offsetMinus.Faces.GetFaceCenter(i), localCSPlanes[i].XAxis, localCSPlanes[i].YAxis)); } for (int i = 0; i <= nEdg - 1; i++) { Line lineRecPlus = offsetPlus.TopologyEdges.EdgeLine(i); edgeMeshPlusLine.Add(lineRecPlus); Point3d recPointA = lineRecPlus.From; recMesh.Vertices.Add(recPointA); Point3d recPointB = lineRecPlus.To; recMesh.Vertices.Add(recPointB); Line lineRecMinus = offsetMinus.TopologyEdges.EdgeLine(i); edgeMeshMinusLine.Add(lineRecMinus); Point3d recPointC = lineRecMinus.To; recMesh.Vertices.Add(recPointC); Point3d recPointD = lineRecMinus.From; recMesh.Vertices.Add(recPointD); recMesh.Faces.AddFace(0 + 4 * i, 1 + 4 * i, 2 + 4 * i, 3 + 4 * i);
NOTE: I know how to create a solid from a single mesh surface, but this is not what I want now, because I have to sort (for further purpose) the solid mesh in top, bottom and side faces.
Thanks a lot for your help!

. From the Thermal Comfort Indices component, Comfort Index 11 (TCI-11):MRT = f(Ta, Tground, Rprim, e)
with:- Ta = DryBulbTemperature coming from ImportEPW component- Tground = f(Ta, N) where N comes from totalSkyCover input. Tground influences the long-wave radiation emitted by the ground in the MRT calculation.- Rprim defined as solar radiation absorbed by nude man = f(Kglob, hS1, ac)- ac is the clothingAlbedo in % (bodyCharacteristics input)- I can't find any definition in the code of Kglob and hS1. Could you tell me please what are those values referencered to? --> probably the globalHorizontalRadiation but how?- e = vapour pressure calculated from Ta and Relative Humidity input
Do you agree that in this case the MRT does not depend on these inputs: location, meanRadiantTemperature, dewPointTemperature and wind speed?It does not depend neither on the other bodyCharacteristics like bodyPosture, age, sex, met, activityDuration...?
MRT calculated by the TCI-11 method is the mean radiant temperature of a vector pointing vertically with a sky view factor of 100%?For ParisOrly epw,
2. From the SolarAdjustedTemperature component (that seems to be more used for the UTCI calculation examples on Hydra compared to TCI-11).
In contrast to the TCI-11, this component distinguishes diffuse and direct radiation and contextualizes the calculation thanks to _ContextShading input, right? It can also be applied to a mannequin thanks to the CumSkyMatrix and thus evaluate the dishomogeneity of radiation exposure.This component seems not to consider the influence of vapour pressure on the result --> is it then more precise to put the MRT output (from the TCI) as an input of meanRadTemperature for SolarAdjustedTemperature?The default groundReflectivity is set to 0.25 --> is GroundReflectivity taken into account in the Tground or MRT calculation in the TCI component? If yes, what is the hypothesised groundReflectivity?The default clothing albedo of 37% (TCI-11 bodyCharacteristics) corresponds to Clothing Absorptivity of 63%?
If the CumSkyMatrix input is not supplied, I get 9 results for the mannequin --> where are those points/results coming from?
If the CumSkyMatrix input is supplied,I suppose the calculation of the 482 results correspond to a calculation method similar to the radiation analysis component that is averaged over the analysis period. Right?But I don't understand why the mannequin is composed of 481 faces and meshFaceResult gives 482 results.
Finally, what is the link between the MESH results, the solarAdjustedMRT and the Effective Radiant field ? Is there a paper to have a detailed explanation of the method?
3. Here are some results for the ParisOrly energyplus weather data. You can find here attached the grasshopper definition.There is no shading in this simulation and the result coming from the ThermalComfort indices for MRT is very different compared to the solar adjusted MRT.Why such a big difference and which of the result should be plugged into the UTCI calculation component?

hope this number will grow in future. Currently available features are:
1) Creation of 2d or 3d context for any kind of building related analysis: automatically generate the 2d/3d surrounding buildings for the location where you would like to perform visibility, solar radiation, cfd or any other type of analysis. You need some other plugin for the last three, like Ladybug. It only creates the context=surroundings! The "automatic generation" process also includes creation of the local topography (terrain) along with buildings.
2) Identification of certain 2d or 3d elements in the created context. For example: selection of all hotels, parks, hospitals, restaurants, residential buildings etc.
3) Performing direct terrain analysis (hillshading, slope, ruggedness, roughness, water flow...)
4) Creation of terrain shading masks and horizon files for further solar and photovoltaics analysis.
Gismo will be very grateful if he could get any suggestions, improvements, bug reports and testing in the following period. In case you are willing to provide any of these, the requirements, installation steps and .gh example files can be found here, here and here.

ion of both Ladybug and Honeybee. Notable among the new components are 51 new Honeybee components for setting up and running energy simulations and 15 new Ladybug components for running detailed comfort analyses. We are also happy to announce the start of comprehensive tutorial series on how to use the components and the first one on getting started with Ladybug can be found here:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDXNep1O
A second one on how to use the new Ladybug comfort components can be found here:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sho45_D4BV1HKcIz7oVmZ8v
Here is a short list highlighting some of the capabilities of this current Honeybee release:
1) Run EnergyPlus and OpenStudio Simulations - A couple of components to export your HBZones into IDF or OSM files and run energy simulations right from the grasshopper window! Also included are several components for adjusting the parameters of the simulations and requesting a wide range of possible outputs.
2) Assign EnergyPlus Constructions - A set of components that allow you to assign constructions from the OpenStudio library to your Honeybee objects. This also includes components for searching through the OpenStudio construction/material library and components to create your own constructions and materials.
3) Assign EnergyPlus Schedules and Loads - A set of components for assigning schedules and Loads from the Openstudio library to your Honeybee zones. This includes the ability to auto-assign these based on your program or to tweak individual values. You can even create your own schedules from a stream of 8760 values with the new “Create CSV Schedule” component. Lastly, there is a component for converting any E+ schedule to 8760 values, which you can then visualize with the standard Ladybug components
4) Assign HVAC Systems - A set of components for assigning some basic ASHRAE HVAC systems that can be run with the Export to OpenStudio component. You can even adjust the parameters of these systems right in Grasshopper.
Note: The ASHRAE systems are only available for OpenStudio and can’t be used with Honeybee’s EnergyPlus component. Also, only ideal air, VAV and PTHP systems are currently available but more will be on their way soon!
5) Import And Visualize EnergyPlus Results - A set of components to import numerical EnergyPlus simulation results back into grasshopper such that they can be visualized with any of the standard Ladybug components (ie. the 3D chart or Psychrometric chart). Importers are made for zone-level results as well as surface results and surfaces results can be easily separated based on surface type. This also means that E+ results can be analyzed with the new Ladybug comfort calculator components and used in shade or natural ventilation studies. Lastly, there are a set of components for coloring zone/surface geometry with EnergyPlus results and for coloring the shades around zones with shade desirability.
6) Increased Radiance and Daysim Capabilities - Several updates have also been made to the existing Radiance and Daysim components including parallel Radiance Image-based analysis.
7) Visualize HBObject Attributes - A few components have been added to assist with setting up honeybee objects and ensuing the the correct properties have been assigned. These include components to separate surfaces based on boundary condition and components to label surfaces and zones with virtually any of their EnergyPlus or Radiance attributes.
8) WIP Grizzly Bear gbxml Exporter - Lastly, the release includes an WIP version of the Grizzly Bear gbXML exporter, which will continue to be developed over the next few months.
And here’s a list of the new Ladybug capabilities:
1) Comfort Models - Three comfort models that have been translated to python for your use in GH: PMV, Adaptive, and Outdoor (UTCI). Each of these models has a “Comfort Calculator” component for which you can input parameters like temperature and wind speed to get out comfort metrics. These can be used in conjunction with EPW data or EnergyPlus results to calculate comfort for every hour of the year.
2) Ladybug Psychrometric Chart - A new interactive psychrometric chart that was made possible thanks to the releasing of the Berkely Center for the Built Environment Comfort Tool Code (https://github.com/CenterForTheBuiltEnvironment/comfort-tool). The new psychrometric chart allows you to move the comfort polygon around based on PMV comfort metrics, plot EPW or EnergyPlus results on the psych chart, and see how many hours are made comfortable in each case. The component also allows you to plot polygons representing passive building strategies (like internal heat gain or evaporative cooling), which will adjust dynamically with the comfort polygon and are based on the strategies included in Climate Consultant.
3) Solar Adjusted MRT and Outdoor Shade Evaluator - A component has been added to allow you to account for shortwave solar radiation in comfort studies by adjusting Mean Radiant Temperature. This adjusted MRT can then be factored into outdoor comfort studies and used with an new Ladybug Comfort Shade Benefit Evaluator to design outdoor shades and awnings.
4) Wind Speed - Two new components for visualizing wind profile curves and calculating wind speed at particular heights. These allow users to translate EPW wind speed from the meteorological station to the terrain type and height above ground for their site. They will also help inform the CFD simulations that will be coming in later releases.
5) Sky Color Visualizer - A component has been added that allows you to visualize a clear sky for any hour of the year in order to get a sense of the sky qualities and understand light conditions in periods before or after sunset.
Ready to Start?
Here is what you will need to do:
Download Honeybee and Ladybug from the same link here. Make sure that you remove any old version of Ladybug and Honeybee if you have one, as mentioned on the Ladybug group page.
You will also need to install RADIANCE, DAYSIM and ENERGYPLUS on your system. We already sent a video about how to get RADIANCE and Daysim installed (link). You can download EnergyPlus 8.1 for Windows from the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/?utm_source=EnergyPlus&utm_medium=redirect&utm_campaign=EnergyPlus%2Bredirect%2B1).
“EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings.”
“OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.”
Make sure that you install ENERGYPLUS in a folder with no spaces in the file path (e.g. “C:\Program Files” has a space between “Program” and “Files”). A good option for each is C:\EnergyPlusV8-1-0, which is usually the default locations when you run the downloaded installer.
New Example Files!
We have put together a large number of new updated example files and you should use these to get yourself started. You can download them from the link on the group page.
New Developers:
Since the last release, we have had several new members join the Ladybug + Honeybee developer team:
Chien Si Harriman - Chien Si has contributed a large amount of code and new components in the OpenStudio workflow including components to add ASHRAE HVAC systems into your energy models and adjust their parameters. He is also the author of the Grizzly Bear gbxml exporter and will be continuing work on this in the following months.
Trygve Wastvedt - Trygve has contributed a core set of functions that were used to make the new Ladybug Colored Sky Visualizer and have also helped sync the Ladybug Sunpath to give sun positions for the current year of 2014
Abraham Yezioro - Abraham has contributed an awesome new bioclimatic chart for comfort analyses, which, despite its presence in the WIP tab, is nearly complete!
Djordje Spasic - Djordje has contributed a number of core functions that were used to make the new Ladybug Wind Speed Calculator and Wind Profile Visualizer components and will be assisting with workflows to process CFD results in the future. He also has some more outdoor comfort metrics in the works.
Andrew Heumann - Andrew contributed an endlessly useful list item selector, which can adjust based on the input list, and has multiple applications throughout Ladybug and Honeybee. One of the best is for selecting zone-level programs after selecting an overall building program.
Alex Jacobson - Alex also assisted with the coding of the wind speed components.
And, as always, a special thanks goes to all of our awesome users who tested the new components through their several iterations. Special thanks goes to Daniel, Michal, Francisco, and Agus for their continuous support. Thanks again for all the support, great suggestions and comments. We really cannot thank you enough.
Enjoy!,

curve or locus] of a segment AB, in English. The set of all the points from which a segment, AB, is seen under a fixed given angle.
When you construct l'arc capable —by using compass— you obviously need to find the centre of this arc. This can be easily done in GH in many ways by using some trigonometry (e.g. see previous —great— solutions). Whole circles instead of arcs provide supplementary isoptics —β-isoptic and (180º-β)-isoptic—. Coherent normals let you work in any plane.
Or you could just construct β-isoptics of AB by using tangent at A (or B). I mean [Arc SED] component.
If you want the true β-isoptic —the set of all the points— you should use {+β, -β} degrees (2 sides; 2 solutions; 2 arcs), but slider in [-180, +180] degrees provides full range of signed solutions. Orthoptic is provided by ±90º. Notice that ±180º isoptic is just AB segment itself, and 0º isoptic should be the segment outside AB —(-∞, A] U [B, +∞)—. [Radians] component is avoidable.
More compact versions can be achieved by using [F3] component. You can choose among different expressions the one you like the most as long as performs counter clockwise rotation of vector AB, by 180-β degrees, around A; or equivalent. [Panel] is totally avoidable.
Solutions in XY plane —projection; z = 0—, no matter A or B, are easy too. Just be sure about the curve you want to find the intersection with —Curve; your wall— being contained in XY plane.
A few self-explanatory examples showing features.
1 & 5 1st ver. (Supplementary isoptics) (ArcCapableTrigNormals_def_Bel.png)
2 & 6 2nd ver. (SED) (ArcCapableSED_def_Bel.png)
3 & 7 3rd ver. (SED + F3) (ArcCapableSEDF3_def_Bel.png)
4 & 8 4th ver. (SED + F3, Projection) (ArcCapableSEDProjInt_def_Bel.png)
If you want to be compact, 7 could be your best choice. If you prefer orientation robustness, 5. Etcetera.
I hope these versions will help you to compact/visualize; let me know any feedback.
Calculate where 2 points [A & B] meet at a specific angle is just find the geometrical locus called arco capaz in Spanish, arc capable in French (l'isoptique d'un segment de droite) or isoptic [curve or locus]
of a segment AB, in English. The set of all the points from which a segment,
AB, is seen under a fixed given angle.…
via MIDI controllers.
my idea is to link PureData to GH via UDP. why pure data? cause' i can relate data like GH to generate numeric relations (and link it to audio generation)
so far i got PD and Processing to talk, but i can't get to grasshopper.
i use this definitions to make pd and processing to talk http://ubaa.net/shared/processing/udp/ and this GHX to get the data to GH http://www.grasshopper3d.com/forum/attachment/download?id=2985220%3...
i got this data from this post but the GH definition doesn't work for me. i have tried LAN definitions and "the engine" as well but they both freeze, even if i send data thru processing or PD.
i have a lot of questions at this time
1.- why processing tells me that i am getting the data from diferent ports, while i'm using 6000?
2.- why in the UDP definition i get no data out, even if it should say something like "waiting fordata/port/etc.." that's defined in the C# capsule
3.- is there a direct way to get midi data (key and CC) to GH
i also tried to use firefly to get the data via COM port. i know you can do this trick in processing but i just don't know how.
well. if anyone could help me i would share the results here (since it's a magister, results shoud be very interesting)
UDP has allways been a unsolved issue on other posts. maybe we could work it out ;)
Thanks…
