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 ...

plug-ins can be found at this website:
http://www.food4rhino.com/?ufh
Th plug-in we were going to focus on yesterday was Kangaroo - a form finding mesh editing software. The instructions for downloading it can be found here, although all computers in the lab should already have it loaded.
http://www.food4rhino.com/project/kangaroo?ufh
Your assignment for next week is found below.
Assignment #6
1. You are to model a membrane shading structure for the WAAC outdoor courtyard adjacent to 1001 Prince Street (seen below).
This is an abstract model - no measurements are required. A basic model would be the walls of the the various building and the ground. Spend a few minutes in the space and get a feeling for what a shading membrane would look like in the space.
2. Use the Kangaroo plug-in to make the mesh. I would look at the tutorials below (do part 2 of the design Analyze as a minimum).
http://www.designalyze.com/tutorial/columbia-meshing-spring-2013-class-04
https://www.youtube.com/watch?v=9i8dGtcQxMk
https://www.youtube.com/watch?v=yY5WU_8L4S8
There is also a manual that comes with the download. It should be on the share file at the WAAC; if not just download it for free at the Food 4Rhino website.
3. It does not matter what your membrane structure looks like, but try to use your eye as a designer. Think about things such as sun angle, experience from both in the courtyard and also from the windows above, support location in the wall etc...
Take a screenshot of the completed image. Do not save to dropbox, but bring to class next week - March 23rd.
Post here if you have any questions. See you all next week!

20%3ATopic%3A1241658&page=2#comments), I have some questions regarding the work mechanism of the lighting control in HB/Daysim.
1) Which specific sensor point (out of many) in the "lightingControlGroup" should fulfill the requirement of "lightingSetpoint" (300lux)?
in other words:
Does it mean that the average illuminance calculated from all the "sensorPoints" in the "lightingControlGroup" (insteady of any single sensorPoint) should fulfill the "lightingSetpoint" requirement?
if this is the case:
Why the lighting schedule obtained from DSElectricalLightingUse is different from the lighting schedule obtained by post-processing/checking all the hourly illuminance results at all the sensorPoints? (please see the attach gh file edited from Mostapha's version)
2) What's the difference, if I hook up "lightingControlGroups_" or not, as shown in the RED arrowhead in the attached file? (Because the results are different as well)
3) If I have a large space (like a 40m*70m sports hall) and want to know its annual lightingControlProfiles, do I need a "lightingControl" component to be hooked on to the "readAnnualResultsI" (in order to calculate its annual lightingControlProfiles)?
If needed, how many "testPoints" I should choose to be used as "sensorPoints_" in the "lightingControl" component?
Thank you in advance for your kind help!
Best,

uld help me to optimize the script, so it works reliable.
At the end the script should work only by the input of the following informations:
- Top-Curve
- Bottom-Curve
- accuracy ( like poly-count)
- is the bowl an open or closed structure?
This is an example of a good result:
From here its probably the best if you open both attached files, so you understand the problems.
1. Bug:
Offset direction of the bottomcurve needs to be set up by hand sometimes.
The script uses "loft" on a bunch of 3pt Arcs to create transitions. Arc 3pts" needs a "Point B" on the offset of the bottom line. Sometimes the offset is inverted, so i need to change it by hand.
The rule to make it work correct is: "The offset of the bottom line goes into the same direction as the top line, but on the same hight as the bottom line."
How can i implement this in GH?
2. Bug:
The floor generation needs a lot of guessing the right index numbers of lists.
The script uses 2x "Deconstruct Brep" to find the actual bottom curve of the created transition Brep. "Patch" is used to create a floor from this curve.
If the bowl is an open structure, the script creates a line between the endpoints of the bottom curve to close it, in order to create a trimmed "Patch". But again, you have to set up the right Index Numbers by hand...
3. Bug:
If the bowl is an open structure and the endpoints of the top-line and the bottom-line are the same the lofting is not working. At the moment I use a script that finds double points in the list and deletes it.
But the the result is, that the loft is not starting at the beginning or the end. Here is an Image.
I have only a little experience in gh, but i really want to learn more.
Thank you all for your help!…
g by a given diameter and some shapes.
What I've done: 1. diameter definition: to find the final object diameter
2. rails definitions: from a initial rails and diameter definition I've find a scaling factor in order to create the final rails with the same form of initial rails but with the wanted distance from the center.
I find the scaling factor using the ray and the distance of a projected point of initial rail to the plane XZ
3. shapes definitions: like the rails definition. I used more than one shape because sometimes I need particular forms along the path.
The sweep 2 rail component gives me a no good result
I tried the options inside the components in order to manipolate the data, but I don't found the solution.
If I bake the final rails and shapes, the sweep 2 rail in RH (selected object) works well, but in GH no (red object).
I attach the RH and GH files for all who can help me Thanks

’s mid-point and whose direction is perpendicular to that edge. The following images are a summary of how I’m currently doing this. Keep in mind that the shared edge is not always parallel with the x, y or z axis… in fact it usually isn’t.
This is the vector I'm trying to get...
This is my workflow:
1- Find centroids of surfaces...
2- Find mid point of the edge. The for each surface, create vector from mid point to centroid and also reverse the direction. Place a point at the end of each vector...
3-Test to see which of the two points for each surface is contained within each surface's boundary and select that point (this parsing is necessary in some cases depending on the shape of the surfaces)...
4-Here is the kicker. In cases where one or both surfaces are skewed, the centroid of that surface is not necessarily "perpendicular" to the mid point of the edges as evident here with surface B. So I create a plane (technically its a "frame") that is perpendicular to the edge...
5-I then pull both points to that plane...
6-From there its pretty straight forward as far as getting the required vector...
So is this the best way to do this. In particular I'm curious if there is an alternative to step 4, but really any comments are welcome.
Thanks,
cbass…
