(unispiring ... I admit)
On recent iOS the app doesn´t work any more, so I figured out, if I should think about making a "light" version of that plant growing thing, with a definition on GH,...
I try to imagine any kind of simple setup to start with,
since I am a middle / low skilled GH user celebrating allways the taste of succes ...running an ordinary GH definition.

onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

BIM is NOT a parametric process at least having in mind graphical editors the likes of GH (or stuff the likes of Generative Components): it's a holistic data management approach. Some concepts used in BIM apps (for instance in AECOSim etc) the likes of "walls"/"openings" etc are "parametric" in the sense that allow auto perforation of this with that. On the other hand AECOSim is feature driven (since Microstation works in that "mode" as well) ... a thing that complex things even more with regard what is actually "parametric" and what not.
BIM is as good as the meta data structure is (especially the spec related aspect - Goggle MasterFormat and the likes). BIM AEC apps are notoriously incapable to work (without a lot of lines of code) with proper RDBMS. On the other hand Bentley Systems ProjectWise ... well ... but that's another animal (by no means a topic for the inexperienced).
In descending order or importance a contemporary AEC practice should use:
1. A general information "controller" like ProjectWise (who said/did what/when/why).
2. A Specs (say CSI - not the TV soap opera) management app.
3. Several Meta data RDBMS.
4. A BIM suite of apps.
5. Optionally some parametric thingy.
PS: For AEC ... when inviting the parametric thingy to the party you have only 2 options:
ProjectWise + AECOSim + Generative Ciomponents (my choice).
?? + Revit + Dynamo.

ess more memory on 64 bits. So you can load larger files and generate more data.
Every time you store something in memory it has to be stored at a specific location. We call this location an address. The first thing you store can be stored at address 0*. If that thing requires a total of 18 bytes, then addresses 0 through 17 are used up. The next thing you store can then be stored at address 18. And so on and so forth. At some point you run out of addresses and when that happens there is no more room to store any new data and there is thus nothing more that your app can do and that's usually when Windows shoots the application in the head and buries the remains behind the chemical sheds.
The total number of unique addresses that can be represented by a 32-bit integer is 4,294,967,295 (4 GigaByte). However Windows only allows a 32-bit app to access 2GB, or potentially 3GB if a special switch is set. A 64-bit application is allowed to use 64-bit integers to identify memory addresses, which means the highest possible address is now 18,446,744,073,709,551,616 (or 18.45 ExaBytes). Basically, as long as you have RAM to back you up, a 64-bit application will not run out of memory. Of course it may still become prohibitively slow as a lot of data requires a lot of computation and 64-bitness does absolutely nothing to make things go faster.

ons of the frets requires the simplest bit of math. The (really) historical technique is called the rule of 18, and it involves successively dividing the scale length minus the offset to the previous fret by 18. [...] The invention of the pocket calculator made it possible to make use of a more accurate constant, and so these days we conventionally calculate fret positions for equal temperament by successively dividing the scale length minus the offset to the previous fret by 17.817.
And from here: http://www.stewmac.com/How-To/Online_Resources/Learn_About_Guitar_a...
The "factor" for fret spacing is 17.817154.
So using Anemone to loop, I got this:
I must admit that it doesn't look quite right, and I'm not sure why...?…
Or if this doesn't work the the lines who's end points Y value doesn't match
5) join all remaining curves. this gives you polylines for each row.
6) From these you can extract control points that will be on differrent branches
i would demonstrate this but i'm stuck watching the wedding at a friend's and until mcneel makes a rhinoid with gh app you'll have to wait 'til later…
omponents and Revit means Dynamo.
Both are masterminded by the very same fella (Robert Aish: an ex Bentley R&D head, then Autodesk paid more [life sucks]).
AECOSim eats Revit for breakfast but has a far steeper learning curve ... meaning that the masses would opt for Revit.…
sites the likes of Code Project etc etc) that may fit to your workflow/goals. Also the available literature/printed manuals/e-manuals/books etc etc.
3. Take into account the quality of the available editors (like VS etc etc). That said the "build-in" GH editor is a bit of a crap (but it's OK for smallish/not complex coding).
4. Most importantly: // computing is the holly grail these days (and it would become the standard in the years to come: either via trad CPU cores or via CUDA/Tesla type of stuff)... thus take into account ... well ... the obvious.
BTW: If 1 is true and there's some workflow around that involves many apps ... try to write code that is as "GH neutral" as possible.…

Bad news: real-life AEC trusses are far and away from lines.
Ugly news: Rhino is NOT an AEC app by any means nor it would ever be. For AEC app I mean the known 3 (Allplan, Revit and my favorite: AECOSim) and/or proper MCAD apps (like CATIA/NX). In plain English : without exporting (meaning (a) bake in nested blocks + (b) export via STEP) proper structured data (assembly/component) this WIP case is absolutely useless.
why may you ask.
well ... trusses are made with numerous shop drawings like this, that's why:
more soon.
best, Peter…
