curves A and B.
For each point pA on curve A,
you need the corresponding tangent vector tA on curve A, and the lists of "cone" vectors pB(j)-pA and tangent vectors tB(j) on curve B. so you have three vectors tA, tB(j) and AB(j)
these three vectors define a parallelogram thas varies along j
3d determinant of the three vectors above gives you the volume of this parallelogram. When 3dDet = 0 then it means it's flat, the vectors are coplanar. Thats what we're looking for.
So you just need to plot the curve 3Ddet = f(pB) , still for each point on A
'pB is the parameter here'
graphically solve these cuves to find the zeros and you feed back the resulting parameter in curve B. draw te line, done.
You can manage double solutions or cusps directly on the plot by using clostest point and >= conditions to kill unwanted results.
I do it twice, from crv A to crrv B and from B to A to make sure I catch start and end generatrices each time.
The videos you posted are interesting. I don't understand how it works with just 2 slider to tune the curves.
…
as passing this extra check and because of that it was running faster. It doesn't mean that the first analysis is totally wrong as it depends on the analysis case and should be checked and optimized before running the final analysis.
You can read more about radiance parameters here (http://radsite.lbl.gov/radiance/refer/Notes/rpict_options.html), and here (http://radiance-online.org/community/workshops/2011-berkeley-ca/pre...). Since you have a light-shelf I suggest you to add to the number of ambient bounces (ab).
Now back to your wish to have the analysis run faster you can comment the line hb_writeRADAUX.checkInputParametersForGridBasedAnalysis() inside Honeybee_runDaylightSimulation and it won't overwrite the initial values but make sure that you run a number of test cases and compare the results between the runs.
Back to your definition, it looks good to me. You could have saved yourself some time by using MassToZone component and then just adding the ceiling separately but there's nothing wrong with your approach.
The main place in the definition that can change is how you're generating the vertical fins. I imagine you can use a single set of components to generate every group of the fins but again your definition will work.
I updated your file to the latest version, which means you also need to update Honeybee and Ladybug in case you're looking to modify the file.
Hope it helps,
Mostapha…

Hi friends,
trying to get a cumulative sky image metric to run and encountered an issue with the image-based metrics component. It throws:
Runtime error (KeyNotFoundException): honeybee_materialLib Traceback: line 768, in main, "<string>" line 1442, in script
I guess this is some sort of setup issue on my end, or I messed up the definition? Any help appreciated.
Thanks,
Max

ace when I start running Galapagos/Octopus (below is "room orientation optimization" shared at http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&fork=hydra_1&id=Room_Orientation_Optimization&slide=0&scale=1&offset=0,0) It may take quite some time to see some results. That's fine for the above simulation. But my real challenge is, when I am going to optimize room dimension with respect to ASE and sDA calculations, either Galapagos or Octopus goes wildly and never come up with a solution. I believe the time-consuming calculation, especially sDA with higher -ab numbers, trigger the lag a lot? Any suggestion/trick to improve it?
Most importantly, based on your experience, for example to optimize window/exterior shades sizes and achieve ASE<10% and sDA>55% (LEED v.4 requirements), Octopus (due to its capacity of multiple objectives) is the only choice? Any other approaches within grasshopper?
The alternative approach in my mind as a GH beginner is as follows. But I am not sure whether it is doable. Again, your comments will be greatly appreciated.
Since all my room/window/shades dimension are controlled by number sliders, I am thinking whether a component from GH will trigger these number sliders (not necessary to be all of them but one by one) automatically. If this is possible, I can do "data recorder" to record outputs from ASE and sDA. Eventually I will have a database of the input parameters and sDA/ASE results.
Does it make sense? Is there a component which can trigger number slider output at certain step?
Many thank!

; GH, this one came out and rhinoceros is disappear...like this
it said " Rhinoceros5's working is stopped. because some problems occured so Rhinoceros5 can't work correctly no longer " then I have no choice but terminate Rhinoceros.
There are some discussion about RhinoIronPython installing numpy though, no one has same problem like me. so Please somebody tell me!!
and one more question...just in case, I tried to install numpy into ironPython2.7

ers and researchers, programmers and artists, professionals and academics who come together for 4 days of intense collaboration, development, and design.
The sg2012 Workshop will be organised around Clusters. Clusters are hubs of expertise. They comprise of people, knowledge, tools, materials and machines. The Clusters provide a focus for workshop participants working together within a common framework.
Clusters provide a forum for the exchange of ideas, processes and techniques and act as a catalyst for design resolution. The Workshop is made up of ten Clusters that respond in diverse ways to the sg2012 Challenge Material Intensities.
Applicants to the sg2012 Workshop will select their preferred cluster from the following:
Beyond Mechanics
Micro Synergetics
Composite Territories
Ceramics 2.0
Material Conflicts
Transgranular Perspiration
Reactive Acoustic Environments
Form Follows Flow
Bioresponsive Building Envelopes
Gridshell Digital Tectonics
More information about the Workshop and Clusters can be found here:
http://smartgeometry.org/index.php?option=com_content&view=article&id=116&Itemid=131
The application process will close on January 15th, 2012.
Full Fee $1500

Scholarship Fee $350
Fees include attendance to both the workshop and conference from March 19th-24th.
Reduced Fee and Scholarships are available only for Academics, Students and Young Practitioners, and are awarded during a competitive peer review process.
sg2012 takes place from 19-24 March 2012 at EMPAC (http://empac.rpi.edu/) and is hosted by Rensselaer Polytechnic Institute in Troy, upstate New York USA. The Workshop and Conference will be a gathering of the global community of innovators and pioneers in the fields of architecture, design and engineering.
The event will be in two parts: a four day Workshop 19-22 March, and a public conference beginning with Talkshop 23 March, followed by a Symposium 24 March. The event follows the format of the highly successful preceding events sg2010 Barcelona and sg2011 Copenhagen.
sg2012 Challenge Material Intensities
Simulation, Energy, Environment
Imagine the design space of architecture was no longer at the scale of rooms, walls and atria, but that of cells, grains and vapour droplets. Rather than the flow of people, services, or construction schedules, the focus becomes the flow of light, vapour, molecular vibrations and growth schedules: design from the inside out.
The sg2012 challenge, Material Intensities, is intended to dissolve our notion of the built environment as inert constructions enclosing physically sealed spaces. Spaces and boundaries are abundant with vibration, fluctuating intensities, shifting gradients and flows. The materials that define them are in a continual state of becoming: a dance of energy and information. Material potential is defined by multiple properties: acoustical, chemical, electrical, environmental, magnetic, manufacturing, mechanical, optical, radiological, sensorial, and thermal. The challenge for sg2012 Material Intensities is to consider material economy when creating environments, micro-climates and contexts congenial for social interaction, activities and organisation. This challenge calls for design innovation and dialogue between disciplines and responsibilities. sg2010 Working Prototypes strove to emancipate digital design from the hard drive by moving from the virtual to the actual in wrestling with the tangible world of physical fabrication. sg2011 Building the Invisible focused on informing digital design with real world data. sg2012 Material Intensities strives to energise our digital prototypes and infuse them with material behaviour. They have the potential to become rich simulations informed by the material dynamics, chemical composition, energy flows, force fields and environmental conditions that feed back into the design process.

y using the Honeybee_Update Honeybee component.
The video below (best viewed in full-screen mode) provides an idea of what these components are capable of being used for:
The video below shows how these components can be used in an existing Honeybee project (for additional links please open this video in youtube):
I have uploaded two examples as Hydra files that show how these components can be used for grid-point and image-based simulations:
Example1 : Grid Point Calculations
Example2: Image based simulation
Finally, a more esoteric application is demonstrated in this video:
These components are still in the beta-testing stage. Some of the limitations of the components are:
1. Only Type C photometry IES files are supported at present.
2. Rhino is likely to get sluggish if there are too many luminaires (i.e. light fixtures) present in a scene.
3. Due to the spectral limitations of the ray-tracing software (RADIANCE), simulations involving color mixing might not be physically realizable.
Additional details about photometric and spectral calculations are probably an overkill for this forum. However, I'd be glad to answer any related questions. Please report any bugs or request new features either on this forum or on Github.
Mostapha, Leland Curtis, Reinhardt Swart and Dr. Richard Mistrick provided valuable inputs during the development of these components.
Thanks,
Sarith

TB of RAM. I think I'm going to start a GoFundMe campaign to buy one for myself :)
2- The server's cost is about $13 an hour. I get free access to supercomputer through my university and xsede.org because I earned an NSF Honorable mention last March, however, the supercomputers available through both resources are a little complicated for me to use, as opposed to the one available from amazon that has Microsoft server 2012 already installed.
3- I wanted to run 400 annual glare simulations for 400 different views.
4- I tried a to perform annual glare simulation for one view on my Dell XPS that has Intel Core i7-6700HQ processor and 16GB of system memory. The simulation took 2 hours to complete. Radiance parameter ab was set to 6.
5- I wanted to obtain the batch file for each view so I can run them on the server. So I used the fly component to run all 400 simulations and closed the cmd windows, that wasn't bad ( for me at least) because I asked my son to this job for me, he was just glad to help me :)
6- I created one batch file using this cmd command:
dir /s /b *.bat > runall.bat
This created a file with the path to each .bat file. I edited this file in Notepad++ to include the word "start" at the beginning of each line. This was done using the "find and replace" dialogue box.
7- I split my newly created batch file into 3 batch files, each one has about 130 file names and " start" before the file names.
8- installed radiance on my server
9- Ran the first batch file on the server, this started 130 cmd windows performing my simulations, CPU usage was anywhere between 90% to 100% and about 105 GB of RAMs were used.
10. It took about 5 hours to complete all 130 simulations, I expected to run all in 2 hours but can't complain because this would've taken about 260 hours to run on my laptop. After the simulations done I ran the second and then the third batch files ( total of about 15 hours).
11. I got 400 valid dgb files. Couldn't be happier!

ss lots of questions,Hope guys show me some more different ways to figure out thoes kinds of problems,Thanks.
That is a construction project,the balconies should be overhang between 1 to 3 meters.
Program A is a patten consist of increasing balconies as the floors get upper.(In the picture is 29 at the first floor and ended with 2 more balconies for each floor, )Each part for a different floor,the twelfth floor have 29+(12-1)*2=51 balconies.
Questions From A,
A1:How to use the {(series)} to creat this atrium,As the floors increase the number of the balconies change by arithmetic progression.
A2:How to control the angle of the balconies,both the angle with floor and the balconies ending part.
Program B is use line to shape the commercial atrium,program A is more small pieces of rectangles.The {(TweenCrv)} command.
Questions From B,
B1:How to draw random points between the 1 to 3 meters region of the balcony,And those point form a shape also belongs to that region.
B2:Use a curve or other ways to control the changing speed of each floors' balcony.Right now the balcony is a Linear change.
Thanks for your Help.
Q1:Is there a way in Grasshopper to control the model to Modulus,less different unit parts to build such a Atrium.(For Exanple,only use 900mm and 600mm two different width of the Glass railings to bulid the model A OR B)…
