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

Grasshopper. So, I once made an attempt to bind ms sqlServer in order to get frozen definitions at some states, to avoid managing baked objects in Rhino and also be able to retain whole results without using the GH state manager that rebuilds everything.
But at that time GH's VB.Net component didn't properly read referenced dlls and I forgot it since then.
At first, I was surprised by Slingshot's extensive interface : I was still having in mind my own old project, a tool that would have acted at the Rhino's geometry object level, and auto creating the needed tables.
The bd would have consisted of a main table, owning the objects ID and name, and related tables containing the necessary information relative to the main objects.
For example, a Brep is made of so and so underlying objects, passed to respective tables, according to GH objects definition layout (just the way they are written in the xml schema).
Then, on a db, query an object by name, and retrieve the whole object or underlying objects (e.g. at the bounding curves level, or points level for a Brep).
With Slingshot, I made a few attempts to cheat GH with BLOB data fields, but no way to get a whole object. It seems that GH simply provides an object.toString ... and GH is definitely not conceived to produce persistence outside of Rhino. If I have some spare time, I will try to extract
About points and colors, I am now simply using a single field with CHAR(asLargeAsNeeded...), as GH parses String to every Point (or Vector or Color) entry of any component.
I do so because it need less to display on the canvas...
Whatever I wrote before, I really like your conception, as opened to relational interactions between ...whatever you need or dream of !
One last thing : GH can't open the definition file "Genome_DB_Template.gh" that I've downloaded from your site : http://slingshot-dev.wikidot.com/database-genome. I was expecting to learn a lot from your very smart stuff ! (I am running GH 08.00.13 and Slingshot 0.7.2.0)
Slingshot is running great, opened to any use...Thanks again.
Best,
Stan

a pain to use sometimes. I recently found this great post:
http://www.grasshopper3d.com/forum/topics/formatting-numbers-in-grasshopper
which points to the msdn .net framework standard numeric format strings:
http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx
and the custom ones too:
http://msdn.microsoft.com/en-us/library/0c899ak8.aspx
Sooo... today I was trying to make a 2D array generator for RGB values to use with a RGB LED and an Arduino. For instance, declaring a 2D array in Arduino:
int color[3][3]={{255,0,0},{0,255,0},{0,0,255}};
I'm using the blend color component to spit out transitions between two colors. I want the list in the panel to be in the format above, so I used both the expression component and the string format component (are they the same under the hood?). In any case, if I have R, G and B values coming into the component, I want to format them so the come out looking like {R,G,B}, so I can just copy the output in a panel and paste it into the Arduino IDE. But what about {curly braces}. If the expression/format component uses them in it's syntax, for instance:
Format ("{R:0},{G:0},{B:0}",R,G,B)
how do I get them into the formatting string? I tried escaping them like:
Format ("\{{R:0},{G:0},{B:0}\}",R,G,B)
but that just makes the component angry
Escaping characters is explained in the formatting references above. Is it implemented in this component? Should I be looking at a different approach?
I've included a sample file below.
Thanks!

For the most part, I got the serial port to work and I could share the port with other components without wiring the components together using a sticky Python dictionary. There were a couple of issues with closing the port (Rhino had to be restarted).
In any case, I'm back at it. I am however going the C# component route with an eye towards writing my own components with visual studio. I am trying to create bidirectional communication with a serial device in grasshopper. I need more control over the serial port that the generic Firefly components can afford. Furthermore, I would like to understand how to program this myself. The first goal would be to create a few components that could handle various serial tasks, one to open/close port, one to read from port and one to write to it. This is not unlike how I got it to work in python, and is also similar to the logic in Firefly's serial components.
The thing that has me stumped with C# is how one shares the port between components? If one component is responsible for creating and opening/closing the port, how do the read/write components address the instance of the port created in the other component? Python has the sticky dictionary, is there something similar in C#? I'm a novice when it comes to C# and how it works within grasshopper, so maybe I'm missing something simple.
I've attached a klunky definition that uses C# to open/close a serial port. I've tried accessing the port with other components, but I don't know enough to make it work. Again, I'm mainly interested in the mechanics of how one component can access the serial port instance created in another component. If I could get some user objects going for now, I'd be happy. In the future, I want to roll my own components. If anyone has any suggestions, code snippets, or any other forms of enlightenment, I'd be greatly appreciative!

When you run the simualtion you will notice on the batch terminal that Daysim is also being called, so you may want to consider how Daysim uses Radiance files & data.
Regarding your current problem, I think you stumbled onto something weird and interesting.
Interior and exterior readings appear to differ by 40 in the best case scenarios. Even setting the transmittance to 1 yields similar results. I tried changing from cummulative sky to climate sky and got similar values. Changing the test points did nothing either.
I think, (yet I'm too lazy to prove this) that the difference in values stems from diffuse radiation over the sky dome.
If you delete everything except the glass you'll notice that interior values are like 80-90% of the exterior values (this seems like the expected behaviour with a transmittance of 1). So, if we consider that a vertical window, part of an opaque box, is receiving radiation from 25% of a sphere, as you start to inset the interior test points the radiation they receive will be a fraction of the 25%.
Let me try to explain this better...The exterior surface receives radiation from a section of a sphere calculated by 180degrees on the xy plane (let’s call this angle theta) and by 90degrees (let’s call this angle phi) in azimuthal elevation. If you integrate this over spherical coordinates (theta from 0 to pi; phi from 0 to pi/2) you will find that it comes to a quarter of a sphere. By comparison, the interior surface will not integrate theta from 0 to 180degrees,nor phi from 0 to 90degrees, instead it will be the subtended angle from the exterior surface as a function of their separation; the farther in you go the smaller the view of the outside.
If my hypothesis is correct there shouldn't be that much difference since the separation is only 10cms...the subtended angle would be like 170 instead of 180 for theta and 85 instead of 90 for phi...overall if you integrate both spherical areas there should only by a difference of 10%.
In conclusion, I believe the unexpected behaviour stems from the previous subtended angle thing. If direct radiation was the only factor the difference would be the aforementioned 10%, which suggests that an additional source of energy is also affected by this. Perhaps indirect and diffuse radiation from other areas of the sky dome.
I’m definitely intrigued on why this is happening. Please post if you figure it out.

Mauricio

when i type the equations for z,y,z it says a syntax error so i obviously do not understand how to construct an expression. (screen capture attached)
Any help/explanation of using this function would be greatly appreciated
thanks so much

r "virtual partitions" as follows:
What I mean "air walls" here, is derived from the description of the E+ documentation with the header of "Air wall, Open air connection between zones". (Page 17, http://apps1.eere.energy.gov/buildings/energyplus/pdfs/tips_and_tricks_using_energyplus.pdf)
As I understand, the term "air wall" used in E+ here refers to a description of something like "boundary condition" between adjacent interzone heat transfer surfaces, but not a kind of "construction or material" (like air space resistance or air gaps within a wall/double glazing window).
The main purpose of introducing the "air wall", is to simulate or approximate the airflow/convection/natural ventilation effect between multiple thermal zones which are connected by a large opening.
In my previous tests, using HBzones and GB, I managed to create the gbXML file which can be successfully imported to DB (without assigning any constructions within HB). And the adjacency condition can be recognized automatically by DB, even when I did not use the "Solve adjacencies" component in HB - shared surfaces between multiple thermal zones are recognized automatically by BD as "internal - partition"(which are standard partitions, but not virtual partitions).
In order to create/approximate "virtual partition", I need to manually draw a "hole" in the standard partition surface (fig.1&2). Again, the reason why we want to use "virtual partitions"(or "air wall") is that it allows airflow between multiple thermal zones which are connected by large openings and we could get different temperature of the each subdivided thermal zone which compose a large thermal zone.
My question is, if there is a possible way to simulate/approximate this kind of "virtual partitions"(or "air wall") in HBzones or in GB? If so, I would like to test if DB recognizes it or not. Actually, we expect that there is no need to involve any manual operations (like drawing a "hole" in the standard partition surface) in DB, due to an automatic optimization loop.
Thank you!
Best,
Ding

d the fact that one pipe goes out and one goes in, that the surface normal direction is opposite for the two surfaces? Based on an earlier thread, you should know why by now. The two curves have opposite directions (again!); see the white arrows using Rhino 'Analyze | Direction'?
As before, you can fix that by flipping one curve to match the other. HOWEVER, you connected your curves directly to the 'Divide' components instead of using 'Crv' geometry params - bad form. And as before, you "fixed it" by reversing the list of starting points ('S' input to 'BiArc'). Better like this - 'Crv' params are internalized, no need for Rhino file:
Well, well! That didn't fix the opposite surface normals after all! Trust me, though, using geometry params and being conscious about matching curve directions is "best practice". But I haven't lofted 'BiArc' curves for awhile, it's late and I want to move on. OH! I just noticed that you reversed the 'Z' direction for one half of the 'BiArc' - that explains it:
Moving on... You've basically got it, though I would do it differently - same result, like this:
I haven't really explained surface normal vectors - can you figure it out from here? One more little wrinkle (Normal_2017Mar17b.gh):
