Comment on: Topic 'Difference between MRT calculation methods'
Thermal Comfort Indices incoming long wave radiation uses Ångström clear sky conditions emissivity coefficient, with Maykut and Church cloudiness factor so that it accounts for cloudy sky conditions. So basically this corrections creates the cloudy (all) skies emissivity coefficient. I was not aware of the fact that .epw files have been shipped with the horizontalInfraredRadiation. Thank you for posting this information!I took a look at EnergyPlus horizontalInfraredRadiation page.In there they state that: "If it is missing, it is calculated".I am pretty much certain that in Serbia, government weather stations do not record the long-wave radiation data.So I thought that this data is probably recorded in more developed countries, definitively in USA.I replicated the formula provided by mentioned bigladdersoftware.com page in cases when "Horizontal Infrared Radiation Intensity is missing".This is the same Clark and Allen (1978) formula mentioned in upper attached Survey of Sky Effective Temperature Models.pdf, Table 3.Once I checked the differences between the Clark and Allen formula and the horizontalInfraredRadiation from the epw file, they were not actually really close, but the same.I checked for a couple of locations in USA, but also outside of it, for different climates. The results were again the same: I attached the file below.I must admit that there are also hours when -1/+1 difference Wh/m2 exists, but my guess is that this is due to rounding of the values which is performed by EnergyPlus as shown in the example at bigladdersoftware.com page (0.036, 0.815, 340.6). So it's either the Clark and Allen formula is super precise and can predict the long wave radiation to be exactly the same as the physically measured value, or .epw weather files are in fact not using physically measured values but calculated ones.My assumption would be that it is the second case. It seems that the only major difference between the two is that the Maykut and Church model seems to be overestimating the long wave radiation loss to the sky in very cold conditions.  Otherwise the models show fairly good agreement Based on upper assumption, I do not think that we can distinguish whether either of these two incoming long-wave radiation methods is more precise or if the other one overestimates the La values.Thank you too for the knowledge and the shared information!!…

Topic: Sorting points
e point in each pair that has the lowest Z value (then later the highest Z)...  The problem is the intersections are not returned sorted by Z, sometimes the lower point is first in the list, sometimes last.  So I need to sort those pairs of points by Z value.I noticed the sort points component does not have any inputs for sort criteria...  RhinoScript SortPoints allows you to sort by: blnOrder Optional.  Number.  The component sort order, where: Value Component Sort Order 0 (default) X, Y, Z 1 X, Z, Y 2 Y, X, Z 3 Y, Z, X 4 Z, X, Y 5 Z, Y, X Will we get something like this in GH?  For now I think I can manage to analyze the Z for each and re-order the points, but a more comprehensive point sorting tool might be nice...  no?  Or did I miss something obvious?  --Thx,  --Mitch…

Topic: Batch View Capture
works joyfully if you want to change parameters and generate screen captures and planning to do a lot of them. You can of course generate the file name dynamically referring to the parameters you gave to the script, so that you have meaningful file names. The example below will generate two captures at J:\Temp\001_top,jpg and J:\Temp\001_front,jpg both at 600X600 px in ghosted mode.       The instructions are as follows: (if you open the VB code by double clicking you will see it) ' Note1: The script is actually calling Rhino commands.    ' Note2: Remember you have to draw something and is selectable for the script to function. The script uses _SelAll then _Zoom _Selected    ' Note3: After you toggle blnSave to True, a new viewport will popup, be patient while Rhino work, and wait for that viewport to disappear befor clicking on anything.    ' Note4: The component is not stable if you try to mouse click on anywhere while the saving process is running. Some stupid move may crash your programme, save RH and GH files before using this component. ' FileName :  String Input    = Supply with the path and file name without ".jpg" extension : e.g.: "C:\Temp\001" (Without the quotes)    ' blnSave :   Boolean Input   = Saves when toggles to True (Remember to toggle back to False after use, otherwise the script will re-run itself during next update)    ' Resolution_width :    Integer Input = Resolution for the captured image    ' Resolution_height :   Integer Input = well...    ' TopYea :    Boolean Input =   Toggles if the Top View is captured (Default is False if not connected)    ' FrontYea :  Boolean Input =   Toggles if the Front View is captured (Default is False if not connected)    ' ...Yea :    Boolean Input =   Toggles if the corresponding View is captured (Default is False if not connected)    ' DisplayMode : Integer Input(0-4) = Sets the display Mode 0:Shaded 1:Wireframe 2:Rendered 3:Ghosted 4:XRay Default:Shaded     I remember I took some code from somewhere but I forgot exactly the source, (if someone could remind me I would love to cite) I rewrite most of them though. But the attribution header in the code still remains there and now it seems a bit interesting to see the family tree:   '////// Marc Hoppermann ///////////tweaked by Damien Almor ///////rewritten for curves by to]///////adapted by u]...www.utos.blogspot.com ///readapted by Victor Leung @ www.dreamationworks.com   Visit my blog if you have time: www.dreamationworks.com…

Topic: facade problem
se (like in nature). the length of the sticks shall be controlled by the brightnessvalues of a picture. so the bend have to be controlled, too. now we have several problems: 1. how can i map a hexgrid on a curved surface? 2. how can i adapt the grid to the dimensions of the surface (no overlap, no gaps to the bound)? 3. important : to create the curved sticks, we use points on a line and we move some of them and then we want to connect the right points via interpolated curve to create each curved stick. now the problem is that the points have to been filtered in the right way. we know that we have to filter each list of points to the index values of the points. the number of index values is the number of hexgrid rows, so there are a lot and we can't use a list item for each one. it could be hundreds. is there any opportunity to sort a list after the index values (first every index=0, then index=1, ...n)? or is there any component which does a group of operations for n-times (n is the flexible number of index values) ? 4. how can i control the length and bend of the sticks via the brightnessvalues of a picture? please help us. thanks.   german version: In einem hexagonalen Raster soll sich senkrecht zu Oberfläche ein Stab im Mittelpunkt jedes Sechsecks befinden. Dieser soll sich ab einem gewissen (festgelegten) Punkt Richtung Boden biegen. Zusätzlich wird die Länge des Stabes zum Beispiel durch die Information eines Bildes gesteuert, so dass auch die Biegung, je nach Länge, geregelt werden muss. Wir haben ein Hexagonales Grid (HexGrid) erzeugt und in jeden Mittelpunkt eine Linie senkrecht zum Grid erzeugt, aus der wir uns Punkte mit CurvePoint ausgeben lassen. Der letzte ist verschoben, um eine Biegung zu simulieren. Um die Punkte zu einer interpolierten Kurve zu verbinden, müssen sie nach dem Index sortiert werden. Gibt es eine andere Möglichkeit, als jeden einzelnen Indexwert über ein ListItem herauszufiltern (Da die Rasterung flexibel einstellbar sein soll, entstehen n Indexwerte)? Oder kann man eine Liste nach den Indexwerten, also nicht nach den Punkten, sortieren? Und wie kann man über Bildhelligkeitswerte die Länge der Stäbe und damit auch die Biegung steuern (ein kurzer Stab biegt sich weniger als ein langer Stab)? Gibt es die Möglichkeit ein hexagonales Raster auf eine gekrümmte Fläche zu mappen? Und wie passt man ein solches Raster (HexGrid) in eine Fläche mit definierten Maßen ein, ohne dass das Raster an den Rändern übersteht oder die Fläche nicht vollkommen ausfüllt? danke.…

Topic: DigitalMed workshop: mapping, parametric design, digital fabrication.
ly 26-27-28-29 (digital fabrication)   The third edition of digitalMed Workshop is structured as a design laboratory. Participants will learn the challenging process of producing ideas, projects and research analysis that are to be developed through specific software and concepts that emerge through the use of mapping, parametric design and digital fabrication.   The workshop will take place in the city of Salerno (Italy) and it will last 11 days structured into 3 intensive weekends: July 13-14-15 (mapping); July 19-20-21-22 (parametric design); July 26-27-28-29 (digital fabrication).     Goals and Objectives: We aim to make clear the theoretical and technical knowledge in the approach to parametric and generative design and digital fabrication. (From collection and data management, to the manner in which these inform the geometries, to the fabrication of prototypes.) Participants will also have the opportunity to practice the new knowledge gained in the design laboratory through project work.   Project Theme: "Urban Field" Identify, study and analyze the system of public spaces in the urban area of the city of Salerno. Connection, mutation, generation and evolution are the themes to be followed in project work.   Brief Description of Topics: - Mapping. Our reality, in all its forms, has studied through concepts of the theory of Complex Systems. The techniques that will be used to study events and places of reality, will work for the management, manipulation and visualization of data and information. These will form the basis for project management and driven geometry, conducted during the second phase of the workshop. - Parametric Design. Introduction to Rhino* and Grasshopper. Specifically, we will explain the concepts with which to work with the software of parametric design and how they function. Through these tools, we will arrive at the definition of systems of mathematical and / or geometrical relationships that are able to generate and govern patterns, shapes and objects that will inform the final design. - Digital Fabrication. In this phase, participants of the workshop are organized into working groups. Participants have access to  materials and conceptual apparatus that will take them directly to the fabrication of the geometries of the project, with the use of software CAD / CAM interface  and the use of machines for the  digital fabrication.   The  DigitalMed workshop is organized by Nomad AREA (Academy of Research & Training in topics of Contemporary Architecture), in collaboration with the City of Salerno,  the Order of Architects Province of Salerno and the National Institute of Architecture In / Arch - Campania.   Interested parties may download the Notice of Competition at the address www.digitalmedworkshop.com and fill the pre-registration no later than July 10th 2012.   PRESS OFFICE Dr. Francesca Luciano 328 61 20 830 fra_luciano@libero.it   For information or subscriptions: e-mail: info@digitalmedworkshop.com - tel: 089 463126 - 3391542980 …

Topic: Grasshopper render animation with VrayToon
nition. Using RenderAnimation component from http://www.giuliopiacentino.com/grasshopper-tools/, I could do all of above except for the Toon material part. I have found a post regarding same matter ( http://www.grasshopper3d.com/forum/topics/how-to-add-materials-to-material-table ), but since I am not very familiar with scripts, this is what I think his definition does. Correct me if I am wrong. Since Rhino Vray only supports Toon environment per material (unlike Max Vray has global override feature), 1. import toon material from Rhino material editor 2. add colors to the toon material and make new toon materials with color (as many as needed) 3. import that new materials back into grasshopper 4. match them with designated geometries and render. (RenderAnimation component by Giulio does this job) Here is the final work he did : http://vimeo.com/34728433 Grasshopper + Vray from Marc Syp on Vimeo. I am using rhino 4 with vray 1.5. I have uploaded my definition, simple definition that transforms box height along with color as frame advances. The definition works but toon effect is not there.…

Topic: Kangaroo matters (relaxing "shapes" to nurbs)
case for sure (started by Giorgio a couple of days before). Ive got involved because I exploit ways to "relax" shapes on nurbs (say patterns created by Lunchbox or "manually) without using any kind of mesh (more explanations soon). Here's 5 test cases (SDK appears that doesn't have some "thicken surface" thing ... thus the algo that finds the "whole" shapes is rather naive) VS 2 Kangaroo "methods" and the why bother (he he) option as well. If the goal is to "fit" these shapes within the nurbs ... does it work so far? No I'm afraid (appears that "springs" used are not the proper ones - or [Kangaroo1 option] the lines that pull should been originated from valance 2 points only) Tricky points: 1. Internalize appears having a variety of serious issues (see Input inside definition) - Load Rhino file first (but even so ...). 2. Pull to surface is deactivated - this is not the issue here (and it's very slow). 3. Since Starling/WB alter the "curves - points" related order the issue here (Pull points to curves) is to correspond apples to apples: and that's what Anemone does: From chaos : to order: this means that prior activating Kangaroo you should double click to the Anemone start component in order to "sort" properly the curves. But .. fact is that results are pathetic: more soon best, Peter…

Topic: Exo W (Ctrl+Alt+Defeat , he he)
Accidentally that was very close to some project that I have in mind (using solely C# and not components). On first sight I thought that that could be very easy ... only to discover that's not. This definition is an over simplified version of the other mentioned (only a C# is maintained that does "preparation" work and some sort of naive "topology" checks: the yellow spheres are used as visual aids to the incompatible struts/R values combos). You can control the 3 options available from that portion: In a nutshell ... the Exo W behaves with an odd way (at least in my opinion). In order to get the gist of the issue stick to that portion of the def and forget the rest: This portion of the def attempts to create an usual Exo mesh using a Line list (cleaned and user controlled as regard the min length) derived from exploded mini voronoi (i.e. brep edges). OK, I can understand the red Exo since due to the nature of voronoi breps there's more than possible the presence of small "struts" that may yield non manifold topologies. But ... the thing is that Exo W is also red in the other mode (non Voronoi) where struts are quite big and no potential "engulfed" situations may occur: And when the 2d Gate mode is set to Envelope ... there's cases (R values) where Exo W works as expected and cases that it doesn't. Anyway ... if anyone has any bright idea, drop a world best, Peter …

Topic: Should I be using Grasshopper w/ Pannelings Tools to do this?
project below-  should I be learning Grasshopper & Rhino or just Rhino first? I'm trying to panel modules with low tolerances- I've prototyped regular shapes like geodesics and am now looking to experiment with  irregular shapes with lots of different panel shapes. I understand some things are best done through Grasshopper when using Paneling Tools- I'm trying to figure out if I can do what I want to achive with PT alone or should do it through Grasshopper (or some other route). I’m on the MAC WIP -  The module was built in Sketchup - all the components seem to be in order as blocks though am having problems running the ptpanel3dcustom command - thinking maybe a bug in the WIP or something wrong with my input or that I imported the sketchup file the wrong way. (I dropped it in the window) - If the 3D command is run it doesn’t do anything - if 2D (ptpanelgridcustom) it crashes. The tileing pattern - the green rectangle is a refrence. each tile contains 4 blocks with 3 more nested in each.  How the module tiles.   The other thing I'm trying to do is specify that most of the lines in the panels don’t bend/curve when they are paneled (or something like Cage Edited). For my purposes the length & angles can change while the lines must remain straight. These images show a test tile to be panneled on a ellipsoid. When the tile is mapped to the grid the lines curve, this is an extreme example but notice allot of tiles far from the hemespheres are also bent slightly. These two questions have me stumped the most for now. What should I look into get a better handle on these problem areas? Maybe I should try recreating the work on a windows machine? or perhaps I should get started with Grasshopper? Thanks for reading. Lu…
