e actual method.
Below, I descibe how they work:
1) drag "scheduleDay" onto the canvas
2) drag some Gene Pool lists onto the canvas and connect a number slider - from 0 to 3.
3) connect the Gene Pool list to _genePool input. The component change some important features of the Gene Pool list automatically. Now you have LB_GenePool!!
4) choose the template that it's suitable for you.
5) disconnect LB_GenePool and if templates are not good, you can change them manually
6) drag "Ladybug annual schedule" onto the canvas
7) Connect LB_GenePools to inputs for the days of the week, Epw file and if you want to "_holiday" (in this way you consider holidays). Now you have your simple schedule.
8) a small workflow to visualize it into Rhino..
9) Connect "Ladybug annual schedule" to "Honeybee_Create CSV Schedule" to make your csv Schedule
You could make a schedule more complex than the one in the example above.
You can do that with _analysisPeriod input.

l coarse mesh
Subdividing this mesh into strips of thin quads
Relaxing/Planarizing this mesh
Splitting and Unrolling
In this post I deal with the first 2 of these stages.
You can download the example definition here:
developable_strips_tutorial.gh
Drawing the initial mesh
To begin with we need a simple quad mesh. This can be modelled manually in Rhino, and only needs to use enough quads to give the topology and very rough form. No need to worry too much about the exact geometry or dimensions at this point, as we will refine and alter it as we go.
One very important thing that we do need to bear in mind though is that all internal vertices must have even valence (I covered this a bit in the earlier post here).
So for example, this is bad:
(because the highlighted vertex is surrounded by 5 faces)
While this is good (and can still be relaxed to the same shape):
(the top and bottom vertices have valence 8, and the vertices between the arms have valence 4)
With a little practice it should be possible to convert any mesh into one that meets this condition.
The reasons why we need this condition should become more clear in the later steps.
First subdivision
This is where we choose how many strips we want our final model to have, by applying a few rounds of subdivision using the Refine component (you could also use Weaverbird here):
Sorting the face directions
While quad meshes do not carry the same information about u/v directions as a NURBS surface, the individual faces do have a sort of direction given by their vertex ordering. However, these face directions are usually not consistently arranged, especially after subdivision.
The Kangaroo MeshDirection component attempts* to orient all the faces in a mesh so that they match with their neighbours.
For example, before sorting, if we draw a line from the midpoint of the first edge of each face to the midpt of its opposite edge, we might get something like this:
Whereas after sorting, we should get something like this:
*note that I say it attempts to orient the faces consistently. In some cases no valid solution exists, for instance if 3 or 5 faces meet around a vertex, hence the requirement mentioned at the start for even valence vertices.
Directional Subdivision
Now that we have consistent face directions across the mesh, we can apply further subdivision, but this time in one direction only. So we go from roughly square quads to thin rectangles. The idea is that as we apply higher levels of this directional subdivision, the final relaxed result goes towards something semi-discrete. A NURBS surface is fully continuous, and a mesh is fully discrete (made up of separate facets), while this strip model will be smooth in one direction and faceted in the other.

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.

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!

ns about them.
It's a direction for Kangaroo I very much intend to continue developing - and I am still getting to grips with the possibilities and experimenting with how different optimization and fairing forces work in combination with one another, so I would value your input and experience.

At the moment the Laplacian smoothing is uniformly weighted, which tends to even out the edge lengths as well as smoothing the form, which is sometimes desirable, and sometimes not. It also tends to significantly shrink meshes when the edges are not fixed.
I plan to try some of the other weighting possibilities, such as Fujiwara or cotangent weighting (see [1] and [3]), as well as other fairing approaches, such as Taubin smoothing [2], Willmore flow[4], and so on. This also has applications in the simulation of bending of thin shells.
Planar quad panels are often desirable, but I'm finding that planarization forces alone are sometimes unstable, or cause undesirable crumpling, so need to be combined with some sort of fairing/smoothing, but the different types have quite different effects, and the balance is sometimes tricky.
There's also the whole issue of meshes which are circular (I posted a demo of circularization on the examples page), or conical (this one still isn't working quite right yet), and their relationship with principal curvature grids and placement of irregular vertices, all of which is rather different when the whole form is up for change, rather than having a fixed target surface [7].
I'm also trying to get to grips with ways of making surfaces of planar hexagons, which need to become concave in regions of negative Gaussian curvature (see this discussion)
and I hope to release soon a component for calculating CP meshes, as described in [8], which I think could have many exciting construction implications.
While there are a number of well developed smoothing algorithms, their main area of application so far seems to be in processing and improving 3D scan data, so using them in design in this way is somewhat new territory. There can be structural, fabrication or performance reasons for certain types of smoothness, but of course the aesthetic reasons are also often important, and I think there are some interesting discussions to be had here about the aesthetics of smoothness.
Anyway, that's enough rambling from me, hopefully something there triggers some discussion - I'm really keen to hear about how all of you envision these tools might be used and developed.
