even (0, 2, 4) then that means the point either never hit it, or went in and out again, meaning it's outside. If it hits an odd number of times, then it must have come from within originally.
The method implements this approach using the mesh bounding box, and then striking a polyline from your test point along a vector that is defined by the upper right corner of the bounding box + a vector of (100,100,100). In the case of your failing points, this is a result of their striking an edge very precisely, which gets counted as 2 hits instead of 1 (as it should be getting captured) and passing false:
Your best bet is probably to roll your own implementation, that tests for multiple vectors:
private void RunScript(List<Point3d> P, Mesh M, ref object A, ref object B, ref object C) {
BoundingBox bb = M.GetBoundingBox(false);
List<bool> inside = new List<bool>();
for (int i = 0; i < P.Count; i++) {
Polyline a = new Polyline(); Polyline b = new Polyline();
a.Add(P[i]); b.Add(P[i]);
a.Add(bb.Max + new Vector3d(100, 100, 100)); b.Add(bb.Max + new Vector3d(100, 150, 150));
int[] fa; int[] fb;
Point3d[] xa = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(a), out fa); Point3d[] xb = Rhino.Geometry.Intersect.Intersection.MeshPolyline(M, new PolylineCurve(b), out fb);
inside.Add(xa.Length % 2 == 1 || xb.Length % 2 == 1);
checkA.AddRange(xa, new GH_Path(i)); checkB.AddRange(xb, new GH_Path(i));
}
A = inside;
}

till quite rough.
I went through your attached log but it seems to be a successful run, perhaps the error log wasn't attached. In any case, I believe we have identified this issue. The goal of the update fvSchemes component was to apply schemes to finalized meshes in an automatic way. While this is useful for new users it is also a dangerous thing to do in CFD studies.
The component works by relating mesh quality to the mesh non-orthogonality, which the checkMesh component reports. While non-orthogonality is one of the important criteria of mesh quality it does present difficulties on some kind of meshes, especially like the simple cases that BF has been meshing so far.
The example case of simple box buildings in a wind tunnel above for instance will appear as a good quality case for even the lowest of cell-count meshes, simply because it is an orthogonal geometry. That means that checkMesh will probably report low values (imagine an empty blockMesh of 10m blocks has a non-orthogonality of 0) which in turn means that higher order schemes might be paired with actually low quality meshes. This I believe is causing problems.
I posted a possible solution to this here https://github.com/mostaphaRoudsari/Butterfly/issues/57. The idea is that Buttefly provides additional options to the users, enabling them to choose between first-order (faster, more robust, but lower quality schemes) and second-order (slower, less robust, but more accurate) schemes depending on mesh quality, stage of assessment, etc. In cases like the above mesh quality a first-order scheme might provide a better option. To test this I am attaching an fvSchemes file you can use by replacing yours in the /system folder of the case.
As a note however, I would like to stress there is so much that a tool like Butterfly can provide in this area. Meshing is a quite complicated and demanding part of the process, involving a lot of trial and error. Sometimes the problem is just the mesh and not the solution options (GIGO stands true in CFD as well). It does however get easier with experience. The safe advice is the simplest one: when changing solution options doesn't help, refine mesh and run again.
Kind regards,

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

nowledge, 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. The Call for Clusters is now open to proposals which respond in innovative ways to this year's challenge.
Deadline: September 19 2011
More information can be found here:
http://smartgeometry.org/index.php?option=com_content&view=article&id=129&Itemid=146
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.

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:

and the custom ones too:

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!
