been covered since 0051 (correct me if I'm wrong):
1) Shoot for the moon first -- "Control Panel Mode" which allows for advanced interface design. See Max/MSP for example of modal function. I spent a lot of time laying out control panels so they are nice for clients and team members to look at. I spend a lot of time disabling wire display and dragging sliders and panels and graphs around into nice little clusters. Could be something as simple as a mode that disables the view of all component handles, cleans up graph objects, sliders, etc. I know the Remote Control Panel has been requested over and over again since it disappeared, but honestly it wouldn't be much use to me unless it was a full blown customizable interface. In the meantime I'll stick to my own "Canvas Control Panel" methods. (See below...)
2) More control over graph objects. Right now the bar graph for instance automatically sets the lowest and highest value displayed. Would be nice to be able to set extents manually so that you can compare apples to apples on two different lists that have different extents. Also would love to force the bar graph to show all values along x axis, not just first and last. Same goes for showing the numbers of instances for each value. Now it only shows instance numbers in oddball cases. Would like to force them to show for statistical purposes. Love percentages, but usually I also want accurate tallies. I tend to use a member index sets to generate my own lists.
3) Color input for Vectors -- there are fakey fake workarounds but none that are as versatile as simply having a color input.
4) COLOR INPUT FOR TEXT TAGS -- sorry to yell... this one really frustrates me. I often build interactive feedback systems that involve a lot of different types of data, and it is difficult to convey that input when all text is red (or green when selected).
5) Ability to justify text tags using paragraph controls -- currently default is left-justified. Would like to be able to center text horizontally and vertically, among other things.
6) Ability for text tags to handle multi-line text. Not sure the best way to implement this, but often I find myself wanting to attach 3 items of information to a particular object, and I have to string it all together in one line. Would be great if I could insert a "^M" character that stands for carriage return and have that display as multiline text (used in conjunction with above justification controls).
7) More control over Text panels. Thank you for including justification options... but sadly now it begs the question for margin and header control. Text slammed up against the left edge is pretty unsightly. Moreover, if you have labeled a text box, the drop shadow from the title bar tends to overshadow the first line of text if you have Path display turned off. Would like to add some header space to fix the problem and create a cleaner look.
8) Easier access to text font size. Buried in a Special Font... menu. I want to be able to up up down down (left right left right select start) if you know what I mean.
I guess that's it for now... just the things on the top of my head in this category. Looking forward to installing the new release, have to wait until this major project is over though.
Cheers,
Marc

o an index, but then you'd end up with consecutive value ranges for the slider that all map to the same index, which I think is actually worse than your current setup. One major benefit of integer sliders is that the number of unique values you can get is usually far less than with floating point sliders.
There is an alternative way to set this up, but I don't know if it's better or worse or indifferent. Instead of definitely using the a and b values, and min/maxing the c and d values to be within some valid domain, you could pit a and c against each other, using those two integers to come up with a' and c'. So for example if {m=10, a=6, c=4}, you'd modify c to be 6+1. Any value of c between 0 and 7 thus yields the same outcome. Instead, you could define a' and c' to be something like a' = Min(a, 0.5*(a+c)), and c' = Max(c, 0.5*(a+c)). This way c will still have a different effect if it's lower than a, by depressing both the a' and c' values. It does sound quite complicated to get right though, I'm not sure I'd bother.
Galapagos doesn't deal with dynamic sliders. It creates genome constraints from the slider properties at the start of the process, and it remembers exactly how many different unique states each slider can be in. Genes then get assigned integers that index each of these unique states.…

[.] Descrizione:
Modulo 1 Il workshop è finalizzato a fornire ai partecipanti i fondamenti della modellazione parametrica e generativa attraverso Grasshopper, plug-in di programmazione visuale per Rhinoceros 3D (uno dei più diffusi modellatori NURBS per l‘architettura e il design). Il workshop mira a gestire e sviluppare il rapporto tra informazione e geometria lavorando sui sistemi di involucro in condizioni specifiche. La discretizzazione di superfici (pannellizazione sia Nurbs che Mesh), la modellazione delle geometrie attraverso informazioni (siano esse provenienti da dati di analisi ambientali, da mappe di colore o da database), l’estrazione e la gestione di informazioni richiedono la comprensione delle strutture dei dati al fine di definire un processo che va dalla progettazione alla costruzione. I partecipanti impareranno come costruire e sviluppare strutture di dati parametrici per informare geometrie ‘data-driven’ e come estrarre le informazioni rilevanti da tali modelli per il processo di costruzione.
Modulo 2 Il workshop, volto a promuovere le nuove tecnologie digitali di supporto alla progettazione e alla fabbricazione, fornirà ai partecipanti, utilizzando Grasshopper, gli strumenti per la preparazione dei modelli 3D di elementi modulari decorativi "bricks & tiles" in argilla la cui successiva prototipazione avverrà tramite fresatura dello stampo con pantografo CNC a 3 assi. Il workshop darà quindi ai partecipanti i fondamenti per l’utilizzo di tale strumento di fabbricazione digitale e si concluderà con la fabbricazione di un proprio modello realizzato durante il corso.

o it would cause troubles with unfolding and fabricating... that's why I used Extrude point component- it will give you similar result, but all surfaces are planar.. you can control extrusion direction with a tip point in rhino...
2)I changed tagging so every tube has 8 points form list A and 8 points from list B... first number of tag is a number of point within one tube... last number of the tag is order of tubes (I draw a little picture in GH, hope you'll understand)...I think original way of tagging wasn't really usefull.. but you can change tagging by yourself...
3) the definition is really messy, sorry about that, but it's just quite complicated task...
4)if you find some incorrect order of tagging, use the slider that controls Shift List component ... it will shift tagging..
5) if you won't be using this definition or find some better way, pleeeease don't tell me - I'll jump out the window :D ... it took me whole day to make it work :D
6)I can't guarantee you anything- I hope it works, but if not - at least I tried... so check everything (especially order of tags and points) twice before you fabricate it.. or print few tubes and make them paper first..
7)there is a part of original definition, that is not useful anymore.. I left it there, but you can delete it (I called it "UNUSED PARTS OF ORIGINAL FILE")
..good luck

hopper and the GH file.
2. There is a drop down menu at the top of Pure Data that reads "Media". Click on "Midi". If your device connection is working, you should see it show up as an option. Set the device to MIDI in. You don't really need to set a MIDI out unless you are planning to send messages back to the device (not sure why you would want to).
3. The boxes labeled "ctlin" with a number are the Control Change in's. In Pure Data go to the "Edit" menu and click on "Edit Mode". Click on one of the "ctlin #" boxes and change the number to match the Control Change number of your physical controller. Mine starts with 5 in the upper right and goes to 65. Each control change number shows up on the display window of my device when I use it which made it easy.
4. Continue this process for all your controls. Delete the unneccesary "ctlin #" boxes by selecting them with a fence and clicking "delete". When you hover over one of the wires you should see and "x". Press the "backspace" key to delete it.
5. Now go down to the "pack f f f ..." box. There should be as many "f" or "floats" in that box as there are you number of controllers. Delete the remaining "f".
6. Next look at the box below that reads "send /0...". Make sure to keep the "/0". If you delete the "/" it will crash Grasshopper. Change the number "5" to match your first control change number. Leave the $numbers alone. You'll want to keep them sequential. Continue change the control change numbers to match all of yours. The $numbers should match the order in which you wired each controller to the "pack f f f..." box.
7. For testing purposes hover over the input on the upper let of the "print" box and connect it to the out of the "send" box. If everything is mapped correctly, working properly, and you go back to the "main" PD window you should see a list of all controllers will a value (0 to 127) next to it. As you turn a knob, the value next to the control change number will increase from 0 to 127. This will give you a good indication of whether or not everything is working and if you mapped it correctly.
8. Click on the "connect OSC" box. You might need to exit out of "edit mode" and back to "performance" mode in the PD canvas.
9. Go To Grasshopper. If everything is working you should see the Panel read "new message" when you turn a knob. At this point it should be pretty obvious how to modify the Grasshopper components. I've tried to keep everything as consistent as possible. Since I filtered out the "/0", the "explode data treat" component starts at 0, the numbers are shifted down by 1.
I just left the IP address, etc. alone on the gHowl UDP component. Just make sure the "port number" matches the OSC port number on the send in Pure Data. If you crash, you may need to choose a new number.
Hope that helps. Let me know if you have any questions. If your computer is not recognizing your midi controller, you may need to install "Midiyoke". I did at first, but it turns out I didn't need it after all.
Best of luck.

of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

1. Select a building to mount a photovoltaic generator on (seen in Rhino in green).
2. Select a surface within that building to mount a photovoltaic generator on (seen in Rhino in green).
3. Create a Honeybee context surface from that surface.
4. Place a photovoltaic generator on that Honeybee context surface by using the Honeybee generation component. Honeybee_Generator_PV and connecting the context surface to it's input _HBSurfaces. Then you can specify both the performance and the financial data of the photovoltaic generator.
5. Create a Honeybee generation system which consists of the photovoltaic generator in 4. By using the component Honeybee_generationsystem and connecting 4 to its input PVHBSurfaces_. Then you can specify the annual maintenance cost of this system.
6. Run the simulation in Energy Plus by connecting 5. to the input HBGenerators_.
7. Read the results of the simulation:
- The electricity produced by the Honeybee generation system in 5.
- The net purchased electricity of the facility (the Honeybee zone) to which the Honeybee generation system is attached to. This is the electricity consumed by the facility less the electricity generated by the Honeybee generation system.
- The financial costs of the Honeybee generation system; capital, maintenance and replacement costs.
8. Calculate the net present cost of the Honeybee generation system in 5 assuming a 25 year lifetime.
9. Visualise the net present cost.

The PC actually stops working because after a few seconds the simulation starts the fan inside the PC all of a sudden stops and for the next 5-10 mins I cannot do anything, even alt+ctrl+canc. After I wait for that time i get the followig error:

The thing is that if I raise the -aa parameter from 0.05 to 0.1 all works fine..
Is this only related to my PC then?? What should I do to solve this issue?
Thanks again for your help
Luigi…
is set up to manipulate strings into an STL file that is quite different from how Grasshopper defines meshes, in that an STL seems to define each face by XYZ points, Grasshopper wants a single list of all vertex points and then has an allied lists of topological connectivity according to vertex number, so for now I just hacked it to spit out points minus so many duplicates it generates for STL:
Right now it has an internal 3D trigonometric function I added input sliders to control, that creates surfaces that look a lot like molecular orbitals.
So how do I make a mesh? I failed to make a single mesh face from each STL face since AddMesh seems to want a list, so I tried making a single list and matching it with a simple ((1,2,3),(4,5,6),(7,8,9)...) array of connectivity but it hasn't worked yet since the STL list of vertices has duplicates that won't work for Grasshopper and removing the duplicates scrambles the connectivity relation.
After some work on this and seeing the output, I figure I could just randomly populate the mathematical function with points instead, unless it really gives a better mesh result than other routines. I'm not sure what to do with it yet, even if I get the mesh figured out.

a given with the third set of information (at the 6th minute). From that, it will then match - for the same exact boats - the speed data given at the 4th minute. Finally it will do a matched subtraction of V(4th) from V(6th) for each boat. Those numbers - whether then scaled up / down or somehow manipulated - will act as the Z dimension which will create the topology. Since V2 - V1 can have a minus value, the overall topology will be a mix of mountains and icebergs this time.
Perhaps to be more accurate, we could divide V2-V1 by 120 and let the topology show the change in speed in a second within that two minutes; the XY coordinates belonging to the latter position of the ships, not the first.
Your definition as you say helps for the linear drawing as it continues from it's stopped. I used that in the current sketch as well for again doing the same thing.However when, I tried to use it for what I am trying to do with the acceleration thing, the result was different. I will try to explain this again;
Let's say that until this point 6 sets of data has arrived - so 12 minutes has passed -. Within that 6 sets, the number of of boats for each one differ as not all of them are able to send data every time. Let's assume in total there are 25 boats and 18 of them have always managed to send data in those 12 minutes. So 18 from the beginning until the end, and finally let's say the remaining 7 of them only could manage to come into the picture at the 4th set of data (so 4,5 and 6).
Now, if I were to build a topology of acceleration for the 6th minute which would mean that I would have to subtract V(4th minute) from V(6th minute) of all 18 vessels, I would need index 2 and 1 from all the branches. If I do this only after 6 minutes has passed from the beginning it would probably work, however if I do it later like at the 12th minute, it does not.
And the very reason for that is when the remaining 7 join the crowd at the 8th minute they obtain an index number of 0, and then 1, and then 2 - at the 12th minute. Because of that when I try to match the V2-V1s with Coordinates on the Unary Force component, while there are 18 sets of coordinates, there are 25 different speed values.
Of course this is quite a simplified scenario and perhaps your vessel matching could solve this specific one but there are cases where its more complicated and random.
I do still want to show vessels' position in a specific time with such pipes you have suggested, but I am trying to construct a collective model, in its simplest form being equal to pipes + topology
For the time thing, what I meant was in this version when you click play the mountains just keep on rising and the topology is constantly deformed. I was wondering if we can set up a timer so that it runs the physics engine for couple of seconds and then freezes the topology as it is. Otherwise I would have to press pause manually everytime, which is not that big of a deal tbh, just for the accuracy sake it would be good to run the engine for the same interval for each model.
All the best,
Levent…
