giornata inaugurale sarà dedicata alla free-lecture introduttiva finalizzata alla realizzazione di un modello d'architettura complesso attraverso l'utilizzo di comandi e tecniche avanzate di rappresentazione con Grasshopper (plug-in parametrica di Rhinoceros) e 3dsMax. Sarà illustrato inoltre il potenziale di V-ray per 3dsMax realizzando un rendering concettuale. Durante il mini-corso dell' openDAY verranno mostrate le caratteristiche e le potenzialità degli strumenti per far luce sui nuovi valori assunti dalla modellazione 3D. La modellazione 3D sta interessando un pubblico sempre più vasto inserendosi in una nuova fase di ampia disponibilità per conoscenze, software, hardware di prototipazione e modelli. Pur mantenendo tutti i suoi valori già noti la questione si è talmente ampliata fino ad interessare norme giuridiche (diritti sui modelli ,concorrenza con offerte di servizi apparentemente simili, informazioni deformate e onfusione nei media) Makers University[http://www.makersuniversity.com], in collaborazione con parametricart, vi propone un punto di vista ampio e sintetico su queste tematiche.
Al termine della free-lecture, sarà illustrata l'offerta formativa [CLICCA QUI] di parametricart riferita ai corsi che si terranno nei mesi di Gennaio e Febbraio 2013 inseriti all'interno della più ampia programmazione della Makers University. SONO PREVISTE TARIFFE PROMOZIONALI PER COLORO CHE SI ISCRIVERANNO AI CORSI durante l'OpenDAY.
La lezione e la presentazione si terranno nel nuovo spazio co-working il PEDONE.

mers considering extreme sports reject mainstream retailers and like to check out small stores rather of at chains plus malls. Several smaller retailers discuss trends in sports shoe sales. http://skateszone.com/
Though athletic shoes and sports stores and from doorways retailers have reported somewhat uptick in footwear sales due to the increase in extreme sports, the particular beneficiaries inside the trend are independent surf and skate niche stores.
Some West Coast surf and skate shops stated teenagers and even more youthful Generation Xers are not only rejecting traditional sports, but they're also shunning mainstream retailers and malls meant for smaller niche shops transporting hard-to-come-by brands.
Eddie Miyoshi, district manager at Atomic Garage, a 3-store chain situated in Gardena, Calif., stated the soaring recognition of skateboard footwear has boosted the retailer's total footwear business 20-thirty percent this year, rather of '95.
Skate footwear presently represent 80-90 % of Atomic Garage's shoe sales, while couple of years back, Dr. Martens and Timberland drove the retailer's footwear business.
Like many retailers, Miyoshi pointed to Airwalk since the trend's catalyst.
However, if Airwalk broadened its distribution to larger chains, which are frequently located in malls, only a few skate shoe customers adopted. Rather, many youthful males have switched for your skate shops for additional elusive brands like Etnies, Duffs, and Electricity Footwear by Circus. By refusing to market bigger retailers or sports stores, these brands are increasing their cachet among youthful consumers.
"Kids don't want stuff which have been within the shops,In . Miyoshi added.
Searching ahead, Miyoshi forecasted skate shoe sales will remain strong through spring '97 provided "the [hot] vendors don't auction other [non-particularly shop] retailers."
"Skaters and non-skaters are rebelling against mainstream retailers so on to surf and skate shops for many looks," echoed Mark Richards, co-online sources Val Surf, a 3-store chain situated in North Hollywood, Calif. Soaring sales of skate footwear have driven total footwear receipts up 25 percent this year rather of '95.
"The quantity of that increase might be connected while using exposure of maximum games? I am unsure. [Skate footwear] may also be actually the think about the moment,In . Richards acknowledged. And in relation to getting this right look, youthful customers can be very picky.
"Skateboard footwear is a huge category for people, but we're not able to own the brands, Etnies, Duffs, Electricity and Nice, simply because they won't sell us," stated Mark Anderson, buyer at Chick's Sports, a six-store chain in Covina, Calif. "We have people coming every single day requesting them." Consequently, skate footwear have consistently ongoing to obtain about 5 % of Chick's overall footwear business. http://skateszone.com/the-top-8-best-skateboards-for-beginners-reviews-2017/
Nonetheless, some outdoors, niche sports and sports retailers are noting the growing recognition and coverage of maximum sports will receive a modest impact on footwear sales. Trailrunning footwear and approach/outdoors crosstrainers will be the two groups benefiting the very best inside the recognition. Like the skate shoe business, some retailers realize that styling instead of function frequently drives sales of individuals footwear.
"At this time the merchandise is a lot more visual than function," stated Chet James, gm of Super Jock 'N Jill, Dallas, speaking about trailrunning footwear. Still, James noted the current hype over adventure sports helps draw more customer traffic. "The marketing campaigns and media help bring growing figures of people in, nonetheless they frequently occasions day an issue that increases results on their own account,Inch he conceded.
John Wilkinson, executive vp inside the 85-store chain Track 'N Trail, Eldorado Hillsides, Calif., stated the shop has "seen some activity in approach footwear," but he requested the amount of consumers depend in it commercially sport. And, instead of accelerating total footwear business, Wilkinson speculated elevated sales of approach footwear and trailrunners are gnawing away at traditional hiking shoe and boot volume.
But Dan Bazinet, president of Overland Exchanging, a 34-store chain situated in Westford, Mass., believes the company-new looks have breathed existence for the wilting hiking boot category. "[Approach-type footwear] don't represent the lion's participate the hiking market, nonetheless they have elevated the hiking business and provided us extra sales," Bazinet stated.
He designated Timberland's Treeline Series and Rockport's Leadville line as strong performers. Unsurprisingly, he noted the company-new looks are attractive to youthful consumer base than traditional hikers.
For that month of June, sales of men's hikers were up 49 percent at Overland, rather of June '95, while sales of women's hikers were up 17 % for that month. Bazinet also attributed elevated sales that shops walked inside the hiking business, departing that business for that specialists.
Some retailers draw a good example concerning the hiking boom of two yrs ago combined with the current extreme sport phenomenon. "Plenty of bigger chains will get a specific percent in the industry while [extreme] sports remain a fad because they are selling cost-point type gear," described Steven Carre, assistant hard goods buyer at Adventure 16, a six-store chain situated in Hillcrest.
"However individuals [true enthusiasts] will say `we need real gear' and may shown up at us. That will help us after a while. What Size Skateboard good for an 3 4 5 6 7 8 9 10 11 12 13 14 year old

now.
This V4 can sense if you feed it with your points and uses these instead of the p1,p2,p3 (it's a prelude for V5 that uses DataTrees of points making any surface subdivision a reality). Do the following: sample a triad of your points (NOT internalized) and feed the C# . Then ... start dragging these Rhino points around (the C# responds accordingly). See any difference?
The topology:
Well, the whole fractal logic (in this case) is to have 3 pts on hand (call them p1,p2,p3 : red, green, blue) and then project the "right" one, say, p3 to the Line (p1,p2) > do this > do that ... blah blah.
But ... what p3? that's the 1M question: Here for instance the right p3 (blue) is (by accident) the 3rd point entered (it's obvious the "projection" recursive logic):
but if you drag around a bit the points : p3 is now different (C# does this by sorting synchronously the triangle angles per point VS points) Numbers are used to indicate that "swift" : (0 for the new p1, 1 for the new p2, 2 for the new p3... etc). Compare with the initial points (red = ex p1, green = ex p2 , blue = ex p3).
and again different:
The 1M question:
In fractal thinking the big thing is when to stop: I could obviously control that by a counter ... but here the requirement is the tile min size (within unpredictable amount of recursions) : this is what the stop logic used does.
The 1B question:
So ... implementing fractal logic (against DataTrees of points) to a parametric environment ... requires a lot of questions: because each time the size of the start triad varies ... whilst the stop condition is constant: meaning that with a little bit of "good" luck you can reach incredible high amount of tiles (computer out of memory > Adios Amigos).
Obviously I'm taking having all possibilities in mind and especially big projects > big facades > millions (or zillions) of tiles > Armageddon > ....

ng in Grasshopper?
As a general recommendation for developers in Grasshopper who are writing a part of their library which is performance-sensitive (please note: often the performance sensitive part is very limited) is to write it in C#, or maybe even C, or maybe even assembly :). Of course, the closer to the machine you will be, the easier it will be to harness all minimal optimizations. However, there is always a compromise between "getting things done" and "making them best" and this boundary is not very easy to catch, right?
If you want to have significant speed improvements for numerical calculations, I would at least recommend developing with C# in a compiled component using Visual Studio or SharpDevelop. The reason is: in order to provide the line number of possible errors, Grasshopper compiles C# scripts in debug mode! They will be much less optimized than what is possible even with today's technology. This does not preclude keeping the project open-source, if that is one of your goals.
Regarding the actual list:
1) Yes, the implied loop will probably be slower than just a simple for loop. This is because Grasshopper code has to keep track of more things than the ones you could be considering with your knowledge of of your very-special case. However, a factor of 10 is simply not acceptable and is likely a symptom of something else. In fact, I think I remember fixing a bug around that in Rhino WIP. However, it appears to be still slower also there. I've added a bugtracking item here.
2) If you are able to do all casts that are involved, and do them as Grasshopper does, please write that code that way. For example, if you supply a curve to an input with number hint, Grasshopper computes the length of the curve. There will have to be an "if" that checks if the input is a curve somewhere (or some similar construct). This aid for designers is what slows down the hint input.
3) Grasshopper has to keep side effects at bay. For example, components B and C are both connected to outputs of A. If you edit data in component B, and that data came from A you of course expect that data to be unchanged in C. This means that, for even lists of numbers, Grasshopper has to perform a deep copy of the output for each input. Otherwise, what happens if B sorts the list and C finds the index of the smallest number? This could be improved if GH components had some way of flagging themselves as non-data-mutating (constant). The fact that, by supplying special types, Grasshopper has no way of performing copies will likely speed things up. But be aware of possibly very annoying side effects creeping in if data is not immutable. Another option is performing the copy "optimally", just where you need it, because you know where your data is used. This is not information that is available to GH at present.
Does this help?

our students could taste first hand the Apocalypse (and/or the brave new world and/or the animal farm - depending on your point of view, he he).
2. First ... make a break and spend some time to play with the def attached. Of course comes straight from the Dark Side (no components of any kind). But you know what? ... sooner or later your students they must obey to the Dark Side ... or they'll extinct (future galloping you know ... I mean in a few years from now anyone not speaking some programming language > Homo heidelbergensis ).
3. This thingy attached works in 2 modes: (a) design a(ny) pattern (in a "flat" Plane.WorldXY) or (b) apply a(ny) pattern (in any given surface List).
Start from here (diamond pattern, like the one used by you):
Apply random Z noise (other pattern used):
Or use surfaces (to make frames or their content among other things):
Note: Although this def attached MAY appear off-topic ... there's a reason (other than using any pattern you like) that I provide this to you : because that way we can totally control nodes, edges and "facets" and therefor extract any plane imaginable and therefor place/manage any imaginable profile.
Note: Of course using the make frames capability (and extruding these BrepFaces AT ONCE both sides) we could obtain "autonomous" [monocoque, so to speak] modular load bearing "panels" ready for assembly (instead of beams + nodes + plates + cats + dogs + why??) ... but this is not exactly what you've asked ... he he.

ints. Anyway this is made for AEC purposes (wavy roofs/envelopes and the likes) and is classified as internal (but I could provide a "light" version).
To give you a very rough idea: C# rebuilds first any input list of nurbs > then samples the control points in a tree > then excludes (or not) the "peripheral" points (case: closed in U/V surfaces) > then "picks" some of them according a rather vast variety of options (~30) > then modifies these either individually (that's only possible with code and it's a bit tricky) or via any collection of push/pull attractors or randomly or ... > then "joins" the 2 sets together (modified + unmodified) > and finally does the new nurbs. Only 456 lines of code that one.
With regard the Dark Side: C# would be my recommendation (P is ala mode, mind) for a vast variety of reasons (less than 10% of them are GH related).
If you decide to cross the Rubicon:
How to go to hell (and stay there) in just 123 easy steps:

The candidates:
C# Fundamentals (Nakov/Kolev & Co)
C# Head First (Stellman/Greene)
C# Language (Jones)

Step 121: open computer
Step 122: get the 30 steps to heaven (i.e. hell)

onents to the latest version and, as you can see, everything works fine:
Over the next week, I am going to be adding in several new capabilities to the Adaptive model in LB+HB that are not an official part of ASHRAE or ISO standards but they are endorsed by the experts and researchers who have helped build the standards. Mostapha, I will be sure to have the component give a comment any time that these un-standardized methods are used and I will be clear that I have made them a part of LB because I have found these insights from new research to be particularly helpful to design processes for passive architecture. Also, I think many of us recognize that both ASHRAE and ISO were initially founded to produce standards for conditioned or refrigerated spaces and that, understandably, they . Among the features that I will be adding in:
1) You will have the option of using either the American ASHRAE adaptive model or the ISO EN-15251 model (see the CBE's comfort tool for a visual of the differences - http://comfort.cbe.berkeley.edu/).
2) In addition to a different comfort polygon, the European standard also uses a "running mean" outdoor temperature instead of the average monthly outdoor temperature. This "running mean" is computed by looking at the average temperatures over the last week and weights each of the daily average temperatures by how recent it is. This makes more sense to me than the ASHRAE method and addresses the issue that you bring up, Alejandro. Needless to say, the updated adaptive model will allow you to use either a running mean or average monthly temperature with either the American or European polygon.
3) The WIP adaptive chart currently has an option for a "levelOfConditioning". This input allows you to make use of research the was conducted along-side the initial development of the adaptive model, which showed that the findings did not contradict the PMV model when people were surveyed in fully conditioned buildings. This parallel research ended up producing a different correlation between the outdoor and desired indoor temperatures and this correlation had a much shallower slope than the official adaptive model for fully naturally-ventilated buildings. The levelOfConditioning allows you to make a custom correlation for full natural ventilation, full conditioning or (presumably) somewhere in between for a mixed-mode building. This levelOfConditioning will become an official input for all LB components using the adaptive model (not just the chart at the moment).
At the end of all of this, I will put together a new video series on Adaptive comfort so that we are all on the same page about how to use the model.

serveral questions:the first thing is in c++ i have to implement more methods than in my c# test project.
they are:
int MyGhComponent::MasterParameterIndex::get(){ return 0;}void MyGhComponent::MasterParameterIndex::set(int index){ }bool MyGhComponent::IsValidMasterParameterIndex::get(){ return 1;}
i found no hint for the implementation of that interfaces. could someone tell me that is correct ?OK, it works, but is it well writen ? What is the MasterParameterIndex?
the second "bigger" problem is, i want to have an output of an pointlist.X y Z 1.2 1.3 1.12.1 5.2 9.2...
my first approch was to use a
void MyGhComponent::RegisterOutputParams(GH_Component::GH_OutputParamManager^ pManager){pManager->Register_PointParam("Coordinate", "XYZ", "Node-Coordinate");}
and
void MyGhComponent::SolveInstance(IGH_DataAccess^ DA){Collections::Generic::List<GH_IO::Types::GH_Point3D>^ pnt = gcnew Collections::Generic::List<GH_IO::Types::GH_Point3D>(); for (int i = 0; i < 10; i++) { GH_IO::Types::GH_Point3D^ point = gcnew GH_IO::Types::GH_Point3D(i, i, i); pnt->Add(i); } DA->SetDataList(3, pnt);}
but this exampel doesn't work...i wirte a small workaround and use the following
pManager->Register_DoubleParam("X-Koordinate", "X", "X"); pManager->Register_DoubleParam("Y-Koordinate", "Y", "Y"); pManager->Register_DoubleParam("Z-Koordinate", "Z", "Z"); Collections::Generic::List<double>^ pntx= gcnew Collections::Generic::List<double>(); Collections::Generic::List<double>^ pnty= gcnew Collections::Generic::List<double>(); Collections::Generic::List<double>^ pntz= gcnew Collections::Generic::List<double>(); ... add .. ect.
this workaround do the job, but i want a better soulution. and i know somewhere out there sould be a better solution. i want to use 3D Points directly in GH without list conversation.
so somebody a familiar with c++ / cli ? and could give me some tipps or a soulution ?
the first thing is: what is the right RegisterOutputParams ?
and witch data type is the right ? Point3d doesn't work. so i try GH_IO::Types::GH_Point3D and Rhino::Geometry::Point3d ...
