Comment on: Topic 'Réseau sur surface': 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. mieux, Peter …; Added by peter fotiadis at 10:15am on March 19, 2015

Topic: What are the icons on a component's input/output parameter?: 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. …; Added by Danny Boyes at 11:41am on March 10, 2014

Topic: Initial Documentation of Thermal Maps: 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.

Topic: Radiation analysis problem "Ladybug": 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.

Comment on: Topic 'VB.net: method for trim and detect the intersection': you will need to deal with all of the curves that intersect the boundry curve, but you will also need to sort through all of the circles inside because the planar surface algorithm won't sort those out for you. The good news is that because you are using circles and linear segments, you can use "pure" geometry equations for some of these intersections instead of relying on NURBS curve "physical" intersections. In the end this means faster and also "more" reliable intersections (especially with the circles). Method 1: Dealing with everything as a phyisical curve... First things first, i guess the "easiest" way to do this would be to translate everything into an OnCurve derived class, and then use the IntersectCurve method to find the intersections. You will need to sort through the resulting ArrayON_XEVENT to find the parameter of each intersection. There should always be 2 intersections, and you're always going to be interested in the intersections of the circle not the boundry curve. To trim the curves, you'll want to use the Split method along with one of the parameters on the curve that you retrieved from the intersection. The only issue is that the split method gets a bit complicated when using it on closed curves. You could either split at both parameters that you retrieved from the intersection results, then sort through the 3 resulting curves to join the two that you need. Or move the start point of the circle to where one of the intersection points happened, translate the other intersection point to the new curve parameter (ie the parameter will be a different number, but it will be physically in the same place), then split with that new curve parameter. Method 2: Try and work with the circles as circles Because you can tell if a circle intersects something by seing if the distance to its center point is less than the radius of the circle, this might be a quicker way to go. If you have the boundry curve as an OnCurve derived class, then you can use the GetClosestPoint method and use all of the center points for each of the circles. The nice thing is that after the 3Dpoint in, and the parameter on the curve that you'll get out, you have the option of supplying a maximum distance. If you do supply that value (use the radius of the circles), then you'll only get a result when the distance is less than or equal to that value. In which case there will be an intersection. To go even further, you can treat the segments of the boundry curve each as a line, and find the closest point/distance to that. That's maybe more complex than your looking to go, but speed wise, it might just be worth it. Take a look at the following link for more code/discussion on the subject. http://www.codeguru.com/forum/showthread.php?t=194400 Part 2: Circle-Circle intersections If you're going to want to make a planar surface out of those circes and the boundry curve, then you'll need to resolve all of the intersections that you have there. Again this is probably something that would be best taken care of by doing some distance tests between the center points of all the circles and seeing if that distance is less than the radius your using. After you've found circles that intersect, you can be try intersecting the curves using the same method mentioned above, or even manually generating the intersection with some trig, but ultimately creating a final result might take a bit of work, especially where you have more than two circles intersecting. The "lazy" way out of this is what's used by the curve boolean command, which is to take each individual curve, make a planar surface from that individual curve, and use standard Rhino booleans to get the result. Luckily you're looking for the union of all those areas, which will be the easiest to create and deal with. After you create the planar surface of each one (RhUtil.RhinoMakePlanarBreps), you can use either RhUtil.RhinoBooleanUnion or the more specialized version, RhUtil.RhPlanarRegionUnion. Note that RhPlanarRegionUnion only takes 2 breps at a time and needs the plane of the intersection.…; Added by Damien Alomar at 11:46am on June 6, 2010

Comment on: Topic 'Refactoring Parametricism': as the design table? I think this could be 'drawn' and constrained in Inventor in a lot less time. I know the GH model would have a lot of flexibility, but in this case, what can you do with it that wasn't provided by an Inventor model? Only the 27 lines mentioned were modeled in Rhino, the rest is modeled with GH. The 5 hrs involved thinking about the approach, defining vertical lines, tilts, elevations, pitch of the roof, intersections. Once I had decided what my approach would be, and tested the logic with those first lines, points and data path arrangements, it only took one more hour to get to this: Which is actually quite fast, compared to MCAD workflows. If you already have components (columns, beams, etc.) modeled and ready to drop into a project, of course it is lightning fast to model simple projects like this example. I am not as much interested in those situations, because improving efficiency is straightforward and obvious. I'm more interested in situations where there are no pre-defined families of objects, in which case you need to start from scratch. The GH model I'm showing is modeled from scratch, except for the 27 lines in Rhino. Here's one obvious advantage to modeling with GH, once the definition is set-up, it's virtually effortless to change inputs and alter the overall design. Here's an example, lets say we wanted to extend the roof 3 more units, curling away from the original direction. Plan view before: And after: An MCAD app will also allow you to do this, as long as the location of additional elements follows the existing geometric method of definition. What happens if you want completely change the way you locate columns, roof slope, intersection points? In MCAD, you'll need to re-model the underlying geometry, which will take the same effort as the first round. In GH, this process is not only much faster, it's open to algorithmic approaches, galapagos, etc. and it just takes some simple re-wiring to have all down-stream elements associate themselves to this new geoemtric definition. For instance, here's the same definition applied to two curves, which are divided in GH, the resulting points are used as a starting point for lines directed at normal from curves. This is not so easy to do in MCAD.…; Added by Santiago Diaz at 7:55pm on February 24, 2011
