ack to .ghx?
This is in relation to a discussion I've been having with David Rutten & Scott Davidson about GH consuming memory in a relatively large GH definition (~. I think what I've learned from this is that one should limit the size of the GH file, or put some incremental stops in the definition to limit the length of calculations that it runs at once. Is this a valid conclusion?
The GH file we're talking about is 7Mb & the Rhino file is about 120Mb, but when working w/ the GH def. I try to only keep about 2 curves turned on.
Here's a summary of the discussion:
Hi Mike,thanks for sending it over. I've been fiddling with the file for about 10 minutes and it climbed from 1.7 GB to 1.9GB, but then I've been switching previews on which means more meshes get calculated so you'd expect a higher memory consumption. It is possible we're leaking memory, but if you're working for hours on end, memory fragmentation might also explain part of the increase. Basically, memory gets fragmented just like disks get fragmented after prolonged use, difference is that memory cannot be defragmented unless you restart the application and allow it to start with a clean slate. I'll try and find any leaks we may have missed in the past.Goodwill,David

Thanks very much David for the quick response. I've attached the files zipped. I can't figure out what's doing it. After working in the file for awhile, the memory usage in the Windows Task Manager climbs . . . it's gotten to 1.57+Gb before I exited GH & Rhino5Wip & let it dissipate, then restart & work for awhile before it does it again. It probably takes like 4 or 5 hours before it gets that high. That's the highest it's gotten, & that only happened while I was working in a Rhino file that had all of the elements baked into it - turned off at least, but it still climbed to 1.57+Gb. It seems to climbs when you work in the file & move around in both the GH def. & the Rhino file. Like turn on a few of the Extr components at the right end of the "StandareRibExtuder" groups, you can watch the MemUsage go up, but when you turn them off, it does not go down. - goes up fast at this point. Maybe I need to figure out how to do the definition with fewer components, I'm sure that's part of it, but I must confess, I think I'm still early on in the learning curve.I really hope that this is not operator error on my part & I do apologize up front if it is. I have done a disk cleanup, I have tried excluding .3dm & .ghx files from my NOD32 antivirus, no change. I hope you can find something.Let me know if you have any trouble with the files.See if you find anything & please let me know . . . thanks!Cheers! --Mike CalvinoCalvino Architecture Studio, inc.www.calvinodesign.com

peuvent se diviser une surface avec ne importe quel motif imaginable. 3. Ici, je fournir un moyen de le faire via Lunchbox ... cela fonctionne mais il est fixe et donc nous avons besoin de jouer avec des arbres de données afin de créer le motif approprié par cas. 4. L'autre composante est un joint C # qui fait beaucoup de choses autres que de diviser ne importe quelle collection de points avec de nombreux modèles (voir le modèle ANDRE que je ai fait pour vous). 5. Vous devez décomposer une polysurface en morceaux afin de travailler sur les subdivisions. 6. Je donne une autre définition ainsi que pourrait agir comme un tutoriel sur la façon de traiter des ensembles de points via des composants de GH standards et des méthodes classiques.
Avertissez si tous ceux-ci apparaissent floue pour vous: Si oui, je pourrais écrire une définition utilisant des composants de GH classiques - mais vous perdrez les variations de motifs de division.

and export the geometry out to VVVV to render it LIVE! RawRRRR. In this case, a digital audio workstation Ableton Live, a leading industrial standard in contemporary music production.
the good news is that VVVV and ableton live lite is both free.
https://www.ableton.com/en/products/live-lite/
i am not trying to use ipad as a controller for grasshoppper. I wanted to work with a timeline (similar to MAYA or Ableton or any other DAW(digital audio workstation)) inside grasshopper in an intuitive way. Currently there is no way of SEQUENCING your definition the way you want to see that i know of.
no more combersome export import workflows... i dont need hyperrealistic renderings most of the time. so much time invested in googling the right way to import, export ... mesh settings...this workflow works for some, for some not ...that workflow works if ... and still you cannot render it live nor change sequence of instruction WHILE THE VIDEO is played. and I think no one wants to present rhinoceros viewport. BUT vvvv veiwport is different. it is used for VJing and many custom audio visual installation for events, done professionally. you can see an example of how sound and visuals come together from this post, using only VVVV and ableton. http://vvvv.org/documentation/meso-amstel-pulse
I propose a NEW method. make a definition, wire it to ableton, draw in some midi notes, and see it thru VVVV LIVE while you sequence the animation the WAY YOU WANT TO BE SEEN DURING YOUR PRESENTATION FROM THE BEGINNING, make a whole set of sequences in ableton, go back change some notes in ableton and the whole sequence will change RIGHT INFRONT of you. yes, you can just add some sound anywhere in the process. or take the sound waves (sqaure, saw, whateve) or take the audio and influence geometric parameters using custom patches via vvvv. I cannot even begin to tell you how sophisticated digital audio sound design technology got last ten year.. this is just one example which isn't even that advanced in todays standard in sound design ( and the famous producers would say its not about the tools at all.) http://www.youtube.com/watch?v=Iwz32bEgV8o
I just want to point out that grasshopper shares the same interface with VVVV (1998) and maxforlive, a plug in inside ableton. audio mulch is yet another one that shares this interface of plugging components to each other and allows users to create their own sound instruments. vvvv is built based on vb, i believe.
so current wish list is ...
1) grasshopper recieves a sequence of commands from ableton DONE
thanks to sebastian's OSCglue vvvv patch and this one http://vvvv.org/contribution/vvvv-and-grasshopper-demo-with-ghowl-udp
after this is done, its a matter of trimming and splitting the incoming string.
2) translate numeric oscillation from ableton to change GH values
video below shows what the controll interface of both values (numbers) and the midi notes look like.
https://vimeo.com/19743303
3) midi note in = toggle GH component (this one could be tricky)
for this... i am thinking it would be great if ...it is possible to make "midi learn" function in grasshopper where one can DROP IN A COMPONENT LIKE GALAPAGOS OR TIMER and assign the component to a signal in, in this case a midi note. there are total 128 midi notes (http://www.midimountain.com/midi/midi_note_numbers.html) and this is only for one channel. there are infinite channels in ableton. I usually use 16.
I have already figured out a way to send string into grasshopper from ableton live. but problem is, how for grasshopper to listen, not just take it in, and interpret midi and cc value changes ( usually runs from 0 to 128) and perform certain actions.
Basically what I am trying to achieve is this : some time passes then a parameter is set to change from value 0 to 50, for example. then some time passes again, then another parameter becomes "previewed", then baked. I have seen some examples of hoopsnake but I couldn't tell that you can really control the values in a clear x and y graph where x is time and y is the value. but this woud be considered a basic feature of modulation and automation in music production. NVM, its been DONE by Mr Heumann. https://vimeo.com/39730831
4) send points, lines, surfaces and meshes back out to VVVV
5) render it using VVVV and play with enormous collection of components in VVVV..its been around since 1998 for the sake of awesomeness.
this kind of a digital operation-hardware connection is usually whats done in digital music production solutions. I did look into midi controller - grasshopper work, and I know its been done, but that has obvious limitations of not being precise. and it only takes 0 o 128. I am thinking that midi can be useful for this because then I can program very precise and complex sequence with ease from music production software like ableton live.
This is an ongoing design research for a performative exhibition due in Bochum, Germany, this January. I will post definition if I get somewhere. A good place to start for me is the nesting sliders by Monique . http://www.grasshopper3d.com/forum/topics/nesting-sliders

ers can be applied from the right click Context Menu of either a component's input or output parameters. With the exception of <Principal> and <Degrees> they work exactly like their corresponding Grasshopper Component. When a I/O Modifier is applied to a parameter a visual Tag (icon) is displayed. If you hover over a Tag a tool tip will be displayed showing what it is and what it does.
The full list of these Tags:
1) Principal
An input with the Principal Icon is designated the principal input of a component for the purposes of path assignment.
For example:
2) Reverse
The Reverse I/O Modifier will reverse the order of a list (or lists in a multiple path structure)
3) Flatten
The Flatten I/O Modifier will reduce a multi-path tree down to a single list on the {0} path
4) Graft
The Graft I/O Modifier will create a new branch for each individual item in a list (or lists)
5) Simplify
The Simplify I/O Modifier will remove the overlap shared amongst all branches. [Note that a single branch does not share any overlap with anything else.]
6) Degrees
The Degrees Input Modifier indicates that the numbers received are actually measured in Degrees rather than Radians. Think of it more like a preference setting for each angle input on a Grasshopper Component that state you prefer to work in Degrees. There is no Output option as this is only available on Angle Inputs.
7) Expression
The Expression I/O Modifier allows you change the input value by evaluating an expression such as -x/2 which will have the input and make it negative. If you hover over the Tag a tool tip will be displayed with the expression. Since the release of GH version 0.9.0068 all I/O Expression Modifiers use "x" instead of the nickname of the parameter.
8) Reparameterize
The Reparameterize I/O Modifier will only work on lines, curves and surfaces forcing the domains of all geometry to the [0.0 to 1.0] range.
9) Invert
The Invert Input Modifier works in a similar way to a Not Gate in Boolean Logic negating the input. A good example of when to use this is on [Cull Pattern] where you wish to invert the logic to get the opposite results. There is no Output option as this is only available on Boolean Inputs.

ing the maps to the broader community.
At the moment, there are just a few known issues left that I have to fix for complex geometric cases but they should run smoothly for most energy models that you generate with Honeybee. Within the next month, I will be clearing up these last issues and, by the end of the month, there will be an updated youtube tutorial playlist on the comfort tools and how to use them.
In the meantime, there's an updated example file (http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Indoor_Microclimate_Map) and I wanted to get you all excited with some images and animations coming out of the design part of my thesis. I also wanted to post some documentation of all of the previous research that has made these climate maps possible and give out some much deserved thanks. To begin, this image gives you a sense of how the thermal maps are made by integrating several streams of data for EnergyPlus:
(https://drive.google.com/file/d/0Bz2PwDvkjovJaTMtWDRHMExvLUk/view?usp=sharing)
To get you excited, this youtube playlist has a whole bunch of time-lapse thermal animations that a lot of you should enjoy:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sj3ehUTSfKa1IHPSiuJU52A
To give a brief summary of what you are looking at in the playlist, there are two proposed designs for completely passive co-habitation spaces in New York and Los Angeles.
These diagrams explain the Los Angeles design:
(https://drive.google.com/file/d/0Bz2PwDvkjovJM0JkM0tLZ1kxUmc/view?usp=sharing)
And this video gives you and idea of how it thermally performs:
These diagrams explain the New York design:
(https://drive.google.com/file/d/0Bz2PwDvkjovJS1BZVVZiTWF4MXM/view?usp=sharing)
And this video shows you the thermal performance:
Now to credit all of the awesome people that have made the creation of these thermal maps possible:
1) As any HB user knows, the open source engines and libraries under the hood of HB are EnergyPlus and OpenStudio and the incredible thermal richness of these maps would not have been possible without these DoE teams creating such a robust modeler so a big credit is definitely due to them.
2) Many of the initial ideas for these thermal maps come from an MIT Masters thesis that was completed a few years ago by Amanda Webb called "cMap". Even though these cMaps were only taking into account surface temperature from E+, it was the viewing of her radiant temperature maps that initially touched-off the series of events that led to my thesis so a great credit is due to her. You can find her thesis here (http://dspace.mit.edu/handle/1721.1/72870).
3) Since the thesis of A. Webb, there were two key developments that made the high resolution of the current maps believable as a good approximation of the actual thermal environment of a building. The first is a PhD thesis by Alejandra Menchaca (also conducted here at MIT) that developed a computationally fast way of estimating sub-zone air temperature stratification. The method, which works simply by weighing the heat gain in a room against the incoming airflow was validated by many CFD simulations over the course of Alejandra's thesis. You can find here final thesis document here (http://dspace.mit.edu/handle/1721.1/74907).
4) The other main development since the A. Webb thesis that made the radiant map much more accurate is a fast means of estimating the radiant temperature increase felt by an occupant sitting in the sun. This method was developed by some awesome scientists at the UC Berkeley Center for the Built Environment (CBE) Including Tyler Hoyt, who has been particularly helpful to me by supporting the CBE's Github page. The original paper on this fast means of estimating the solar temperature delta can be found here (http://escholarship.org/uc/item/89m1h2dg) although they should have an official publication in a journal soon.
5) The ASHRAE comfort models under the hood of LB+HB all are derived from the javascript of the CBE comfort tool (http://smap.cbe.berkeley.edu/comforttool). A huge chunk of credit definitely goes to this group and I encourage any other researchers who are getting deep into comfort to check the code resources on their github page (https://github.com/CenterForTheBuiltEnvironment/comfort_tool).
6) And, last but not least, a huge share of credit is due to Mostapha and all members of the LB+HB community. It is because of resources and help that Mostapha initially gave me that I learned how to code in the first place and the knowledge of a community that would use the things that I developed was, by fa,r the biggest motivation throughout this thesis and all of my LB efforts.
Thank you all and stay awesome,

I live on my computer and I even sleep with it, so learning all this is probably within my reach but I'm a complete beginner as of now.
I'm downloading the 32 bit version of rhino 5 since the 64 bit doesn't seem to work with your downloads Jon.
I haven't grasped everything you have made yet Jon I can't even begin to understand what your IFC stuff is actually capable of, but just to be clear I'm not interested in solely being able to tell that something is colliding as there are already software that can do that beautifully. What I want to do is bypass that step altogether by never having collision-checking back and forth go on, even collisions which aren't physical collisions, but rather just violations by code. The simplest way to do this would be to simply make the geometry of the beams 2 feet wider than they are in real life, so that way you could put a light right next to the 'over-sized' beam and it would still be within the rules. But that would be extremely primitive and I'm sure there's a way to do it mathematically.
Just to clarify, I'm the fire sprinkler designer in the architectural circus. The sprinkler designer (me) doesn't really get the luxury of telling the other trades that they're colliding with my stuff and they should move. Rather, I get their drawings, find out I'm colliding with them, and move around them. So it would be of great use to me to have this be automatic - that is, to automatically space my sprinklers the neccesary distance away from all obstructions. There are different spacing rules for different obstructions - walls, beams, open web steel, unit heaters, hvac ducts depending on how wide the ducts are, lights, fans, high rack storage, basically anything that would obstruct the water spray from a sprinkler needs to be taken into account and spaced away from.
It's therefore a very attractive idea to be able to just draw a rectangle (representing the walls of a simple room) for instance, have the sprinklers automatically spaced as far apart as possible within the rectangle according to the rulebooks (to minimize the amount of sprinklers needed which minimizes the material cost of the job).
Then add obstructions inside the rectangle, such as a beam, and have the sprinklers relocate themselves or add new sprinklers to accommodate for the new obstruction.. Keep adding obstructions until you have the realistic 3d model of the room, with the sprinklers spaced accordingly, and you have an up-to-code sprinkler system.
There is one example where sprinklers actually need to be spaced really close to, rather than away from, an object.. and that is the ceiling (sprinklers must be within 12 in of ceiling typically).
If the HVAC guy decides to reroute his ducts right through my sprinklers, then I could draw 3D HVAC ducts (I usually get 2D drawings coming in) going right through the room and the sprinklers would relocate and auto-space away from the ducts, without actually having to tell the HVAC guy he is colliding with me because all that will do is require me to do a redesign anyway.
And presto, the HVAC guy loves me because I didn't complain to him at all and seemingly did all this work by moving around him when all I really did was use the computer to do it, the job gets done much faster and I don't have to worry that I'm going to lose my job in court because I made a silly human error when I was patching my system manually because some HVAC guy made me redesign 12 times in different places.
From what I have been reading from you guys, doing this is possible although (I realize) ambitious. The end result would be vastly increased productivity, less error making, cheaper design cost, etc. Using programs like Rhino, architects are getting more and more funny-shaped buildings and making it difficult for guys like me to make sprinkler systems within the rules, and I see it as an inevitability that computers will be making almost all of the typical design decisions in the future when it comes to life safety systems, I'm just trying to see if it's possible to start implementing this extra aid today.

But not just any gum tree. The angophora, no less:
Why? Because I like nature, that's why. Every time I see new designs –especially architectural designs– it worries me that the natural environment is being taken over. Not just that, but even the new materials used in all product designs has to come from nature as well [read: mines].
So. People are forgetting that we still need trees and I believe that if someone sees a beautiful [read: established] tree in their architectural plans, they are going to be much more likely to build around it and not cut it down. That alone would no doubt increase the value of the house.
My thinking is that current tree models suck. They look unnatural and I think I know why. They're not random or organic enough. They're not detailed enough. That's basically my 'rationale' for this project. Just look at how different all of these tree trunks are!
So I am not being paid for this project. It's a personal project of mine. I'm just worried about the trunk shape for now — I'll worry about all the leaves... when I get to that.
I am a grasshopper beginner. Please keep that in mind. I am also fairly hopeless at traditional programming, but I find the visual approach of grasshopper much easier to grasp. So unfortunately I have gotten stuck and need some help, even just a clue, as to how to proceed.
That said, here is my current progress:
About a year ago, I started modelling with straight trunks using pipe sections, to see if I could get a very basic "tree" shape. And to see if I could join the segments together. Yes it works but it looks hopeless as you can imagine. Then I stopped for a long while. Now I'm back at it, hoping to improve a lot more.
I have already made one basic vertical nurbs curve with tangents at either end as the main "trunk".
I tried creating two ellipses at each end of the main trunk/curve and lofting between them but it omitted the main curve/rail. So it ended up being an elliptical trunk with straight sides which of course still didn't look right.
Then I divided the first main curve up into a number of segments. I think that is a better approach.
I have taken the parameters of the curve at each segment (probably the tangent, but I am unsure what the exact parameter is) and used that to form a basic angled plane at each segment/division.
I have been able to draw ellipses at each segment and rotate them onto the plane.
I was going to loft it together later on. A Curved loft with elliptical cross-sections looks much better than straight a pipe does, but still looks too unnatural.
I quickly realised that tree trunks are not elliptical, but rather, shaped more like 'kidneys'.
The next step was to create >3 points on each of those planes (spaced fairly evenly around the ellipse so as not to create a really funky/unwanted shape).
Maybe it would be better to model with a triangle or other polygon instead of an ellipse. I haven't got that far yet... because here is where I am getting stuck.
I managed to find a way of getting three roughly 'triangular' points along each that ellipse.
I also managed to create three nurbs cuves in the Z direction which intersected those three points, a bit like three seams down the side of the tree trunk, but couldn't figure out how to loft it all together.
I think it was the wrong approach anyway... I'd rather try to create a bunch of nurbs curves at each of the XY planes so as to get more control of the shape.
What I am trying to do now is create three roughly triangular-spaced points on a basic ellipse through which I can then draw a simple nurbs curve (think like a cross section of the trunk).
I would then like to add some XY-only randomness to the positions of those points. Not Z randomness, otherwise the trunk is going to get messed/kinked up. That's probably very important.
Then I would like to loft those nurbs curvs at each XY plane together forming the basic tree trunk, which also tapers based on some other variable (a non-linear factor, not simply distance from ground plane, perhaps something else?).
I have attached the GH file.
I am also open to suggestions if you have a better way of solving a problem. I would like to retain control over a lot of factor such as number of branches, spacing, average branch length, etc. My main contrsaints are that the entire thing has to be somewhat random and non-linear.
