len , I lost all of my work (at least the 3d modeling)
And I frankly if I want to participate I´ll need to finnish up the board and i cant do the renders on my own I need more time , but I only have until 11:59 pm of July 6 to finnish up one render, if you feel up to the challenge, whoever completes it will receive 290 dollars (its all I can give) to any account you want. I basically need one single image.
It consists on 3 towers, with an organic facade, I'm including the competition board I had saved on in my dropbox, I want more or less the same perspective shown on the left of the board.
Sorry, but i'm desperate, I had it all done but well cant control everything in life i guess, only do it if you feel you can pull off a professional render.
Thanks. (contact me and I´ll give you more info on the towers, I was able to save some limited sections and floor plans .... but yeah.. limited, so you´ll have to base your work on the images I provide here.
I can give some files now, including images of the physical model.
Board: http://i.minus.com/idYpFK844DWns.jpg
Physical model: http://imgur.com/a/PywJa
Hope its enough, I'm also including one image i had where I explored the footprints of all the buildings, but its just for reference.
I know theres barely enough time to finnish it... but I dont know what else to do, do you guys think i should probably just take a good photograph of the model and run with that? I feel that would probably look very unprofessional :l but I really dont have a choice here
…
that are available, I found myself in a quite difficult problematic.
I did a lot of google search/work and found some information, but still kind of haven't got the information that I need or want to use. Note: Our school has provided us 3 hours of basic Grasshopper tutorial and one hour of Honeybee/Ladybug temperature tutorial (with weather data etc).
For now I have used Grasshopper and Kangaroo, haven't quite implemented other plugins.
What I want to achieve?I want to create a basic wind simulation in a room (cube at first, but then add more space and use different models) that I can change inside grasshopper. For example I have two openings. I blow wind inside the object from one opening and it goes out the other opening. When I change the wind parameters I can analyse the wind and data that is flowing through the cube.
Is there a way I can visualize the wind?
I have seen different solutions, but mainly vectors with colors that are visualized as wind direction and temperature. Is it possible to make it 3D that I can actually make a real-life model out of it?
Why cube?At first I want to test it and see how it works, if it is viable or not. In the end I would create a facade that is designed for natural ventilation. I am kind of trying to put two projects together. One for the wind analysis, the other for the 3D-Result that is created with the wind. It might be a quite awful that I am asking, but I don't know where to go after doing the google research. Also, some Grasshopper links I found that might help describe the situation. http://www.grasshopper3d.com/forum/topics/wind-analysis-by-grasshopperhttp://www.grasshopper3d.com/forum/topics/wind-cfd-change-form(Should I approach it with Ladybug and Ecotect?)

REGISTER HERE
One of the characteristics of contemporary design is a clear reduction of all visible connections, pursuing the idea of a seamless flow of curves and surfaces. From product design to automotive, from naval design to architecture’s envelope, understanding and managing surface continuity is an essential skill. The online webinar “Zebra” will introduce attendees to the notion of surface continuity in Rhino-Grasshopper. The lesson will cover mathematical aspect of curvature continuity, modeling strategies and practical examples. Contents are intended for users with basic knowledge of 3D modeling in Rhino. The webinar will be a fully interactive event hosted “live” but also available as a recorded video. Registrants will be able to re-watch it anytime. Zebra is part of our Parametric Vibrations webinar series. Tutor: Arturo Tedeschi. Language: English.
Main Topics:
NURBS representation
Notion of curvature for curves and surfaces
Curvature continuity for curves and surfaces: G0 – G3
Surface continuity in Rhino. Analysis tools: curvature analysis, Zebra, environmental map
Surface continuity in Rhino: tools, modeling strategies and tips for surface continuity.

sinergetici associati alla compresenza simultanea di differenti strumenti di analisi e digital design all'interno di un processo di progettazione in svolgimento. I partecipanti utilizzeranno Grasshopper (modellatore parametrico per Rhino): l'uso di questo editor grafico di algoritmi si integra alla perfezione con gli strumenti di modellazione di Rhinoceros 3D espandendo le possibilità di corstruire modelli parametrici altamente complessi. Per generare una complessità simile saranno utilizzati collegamenti live ai diversi programmi elencati di seguito: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI Durante questi intensi 3 giorni, i partecipanti impareranno il workflow dei plug-ins con l'aiuto di esempi esplorando una panoramica dei differenti software, le possibilità di testare le performances di un progetto o l'uso di strumenti addizionali non legati ad un singolo sistema (es. accentuazione, formazione, reazione parametrica) [english text] The focus of the workshop is to integrate and correlate the synergistic effect associated with simultaneous presence of different digital design- and analysis tools in an ongoing design process. The main attention is set on easy to handle interface , which should be used at a early stage of conceptual design to respond to external and internal influences in a intelligent and sustainable way. Participants will use the software Grasshopper as a parametric modeling plug-in for Rhino. The usage of this graphical algorithm editor tightly integrated with Rhino's 3-D modeling tools open up the possibility to construct highly parametrical complex models. To generate this complexity we will use live linkages to several programs listed below: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI In this 3 intense days, the participants should learn the workflow of the plug-ins with the help of examples and get an overview of the different software's, there possibilities for evaluating the performance of a design or the usage of additional tools to be not chained to a single system .

ion of both Ladybug and Honeybee. Notable among the new components are 51 new Honeybee components for setting up and running energy simulations and 15 new Ladybug components for running detailed comfort analyses. We are also happy to announce the start of comprehensive tutorial series on how to use the components and the first one on getting started with Ladybug can be found here:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDXNep1O
A second one on how to use the new Ladybug comfort components can be found here:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sho45_D4BV1HKcIz7oVmZ8v
Here is a short list highlighting some of the capabilities of this current Honeybee release:
1) Run EnergyPlus and OpenStudio Simulations - A couple of components to export your HBZones into IDF or OSM files and run energy simulations right from the grasshopper window! Also included are several components for adjusting the parameters of the simulations and requesting a wide range of possible outputs.
2) Assign EnergyPlus Constructions - A set of components that allow you to assign constructions from the OpenStudio library to your Honeybee objects. This also includes components for searching through the OpenStudio construction/material library and components to create your own constructions and materials.
3) Assign EnergyPlus Schedules and Loads - A set of components for assigning schedules and Loads from the Openstudio library to your Honeybee zones. This includes the ability to auto-assign these based on your program or to tweak individual values. You can even create your own schedules from a stream of 8760 values with the new “Create CSV Schedule” component. Lastly, there is a component for converting any E+ schedule to 8760 values, which you can then visualize with the standard Ladybug components
4) Assign HVAC Systems - A set of components for assigning some basic ASHRAE HVAC systems that can be run with the Export to OpenStudio component. You can even adjust the parameters of these systems right in Grasshopper.
Note: The ASHRAE systems are only available for OpenStudio and can’t be used with Honeybee’s EnergyPlus component. Also, only ideal air, VAV and PTHP systems are currently available but more will be on their way soon!
5) Import And Visualize EnergyPlus Results - A set of components to import numerical EnergyPlus simulation results back into grasshopper such that they can be visualized with any of the standard Ladybug components (ie. the 3D chart or Psychrometric chart). Importers are made for zone-level results as well as surface results and surfaces results can be easily separated based on surface type. This also means that E+ results can be analyzed with the new Ladybug comfort calculator components and used in shade or natural ventilation studies. Lastly, there are a set of components for coloring zone/surface geometry with EnergyPlus results and for coloring the shades around zones with shade desirability.
6) Increased Radiance and Daysim Capabilities - Several updates have also been made to the existing Radiance and Daysim components including parallel Radiance Image-based analysis.
7) Visualize HBObject Attributes - A few components have been added to assist with setting up honeybee objects and ensuing the the correct properties have been assigned. These include components to separate surfaces based on boundary condition and components to label surfaces and zones with virtually any of their EnergyPlus or Radiance attributes.
8) WIP Grizzly Bear gbxml Exporter - Lastly, the release includes an WIP version of the Grizzly Bear gbXML exporter, which will continue to be developed over the next few months.
And here’s a list of the new Ladybug capabilities:
1) Comfort Models - Three comfort models that have been translated to python for your use in GH: PMV, Adaptive, and Outdoor (UTCI). Each of these models has a “Comfort Calculator” component for which you can input parameters like temperature and wind speed to get out comfort metrics. These can be used in conjunction with EPW data or EnergyPlus results to calculate comfort for every hour of the year.
2) Ladybug Psychrometric Chart - A new interactive psychrometric chart that was made possible thanks to the releasing of the Berkely Center for the Built Environment Comfort Tool Code (https://github.com/CenterForTheBuiltEnvironment/comfort-tool). The new psychrometric chart allows you to move the comfort polygon around based on PMV comfort metrics, plot EPW or EnergyPlus results on the psych chart, and see how many hours are made comfortable in each case. The component also allows you to plot polygons representing passive building strategies (like internal heat gain or evaporative cooling), which will adjust dynamically with the comfort polygon and are based on the strategies included in Climate Consultant.
3) Solar Adjusted MRT and Outdoor Shade Evaluator - A component has been added to allow you to account for shortwave solar radiation in comfort studies by adjusting Mean Radiant Temperature. This adjusted MRT can then be factored into outdoor comfort studies and used with an new Ladybug Comfort Shade Benefit Evaluator to design outdoor shades and awnings.
4) Wind Speed - Two new components for visualizing wind profile curves and calculating wind speed at particular heights. These allow users to translate EPW wind speed from the meteorological station to the terrain type and height above ground for their site. They will also help inform the CFD simulations that will be coming in later releases.
5) Sky Color Visualizer - A component has been added that allows you to visualize a clear sky for any hour of the year in order to get a sense of the sky qualities and understand light conditions in periods before or after sunset.
Ready to Start?
Here is what you will need to do:
Download Honeybee and Ladybug from the same link here. Make sure that you remove any old version of Ladybug and Honeybee if you have one, as mentioned on the Ladybug group page.
You will also need to install RADIANCE, DAYSIM and ENERGYPLUS on your system. We already sent a video about how to get RADIANCE and Daysim installed (link). You can download EnergyPlus 8.1 for Windows from the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/?utm_source=EnergyPlus&utm_medium=redirect&utm_campaign=EnergyPlus%2Bredirect%2B1).
“EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings.”
“OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.”
Make sure that you install ENERGYPLUS in a folder with no spaces in the file path (e.g. “C:\Program Files” has a space between “Program” and “Files”). A good option for each is C:\EnergyPlusV8-1-0, which is usually the default locations when you run the downloaded installer.
New Example Files!
We have put together a large number of new updated example files and you should use these to get yourself started. You can download them from the link on the group page.
New Developers:
Since the last release, we have had several new members join the Ladybug + Honeybee developer team:
Chien Si Harriman - Chien Si has contributed a large amount of code and new components in the OpenStudio workflow including components to add ASHRAE HVAC systems into your energy models and adjust their parameters. He is also the author of the Grizzly Bear gbxml exporter and will be continuing work on this in the following months.
Trygve Wastvedt - Trygve has contributed a core set of functions that were used to make the new Ladybug Colored Sky Visualizer and have also helped sync the Ladybug Sunpath to give sun positions for the current year of 2014
Abraham Yezioro - Abraham has contributed an awesome new bioclimatic chart for comfort analyses, which, despite its presence in the WIP tab, is nearly complete!
Djordje Spasic - Djordje has contributed a number of core functions that were used to make the new Ladybug Wind Speed Calculator and Wind Profile Visualizer components and will be assisting with workflows to process CFD results in the future. He also has some more outdoor comfort metrics in the works.
Andrew Heumann - Andrew contributed an endlessly useful list item selector, which can adjust based on the input list, and has multiple applications throughout Ladybug and Honeybee. One of the best is for selecting zone-level programs after selecting an overall building program.
Alex Jacobson - Alex also assisted with the coding of the wind speed components.
And, as always, a special thanks goes to all of our awesome users who tested the new components through their several iterations. Special thanks goes to Daniel, Michal, Francisco, and Agus for their continuous support. Thanks again for all the support, great suggestions and comments. We really cannot thank you enough.
Enjoy!,
Ladybug + Honeybee Development Team

I'm assuming there will be some serious bugs. I'll upload a new installer friday-evening with all available fixes. Until then, you can get the pre-release here:
EXE installer
and a zipped version of the same installer:
ZIP installer
Known problems:
- Layout logic has been largely rewritten, which means that components and parameters will appear slightly shifted when loading old files. Panels, ParamViewers, Sketches etc should remain in place.
- Many core functions and classes have been changed. This will affect those VB and C# components that were calling directly into Grasshopper. Several of Giulio Piacento's components (TheEngine, BakingTools) will no longer work for example.
- Clusters have been removed entirely (trust me, there's a good reason for this), so any file you load that had clusters will give you IO warnings and the cluster contents will spill directly onto the canvas (functionality should remain the same).
New Features:
- Params.Special.ParamViewer now has scrollbars if the data description exceeds the visual rectangle.
- Params.Special.ParamViewer now has an alternative display mode which draws a graphic representation of the data tree.
- VB and C# component type hints are now much more robust.
- Zoom Selected button in View menu and Canvas Toolbar.
- Enable/Disable Solver switch which allows the user to completely switch off Grasshopper updates. This global switch replaces the RhinoEvents and Grasshopper events toggles, which were document bound.
- It is now possible to save and restore states ([Solution->Save State...] and [Solution->Restore State] menu). Sliders, Graphs, Boolean Toggles, Colour Swatches and Gradients can be included in a state record.
- ASSERTS can now all individually be discarded for the remainder of the runtime process.
- Discarded ASSERTS can be re-enabled via the [Solution->Clear Exception Ignore List] menu.
- Save operations are now echoed in the status bar, so there is feedback when using Ctrl+S.
- Deselect objects by pressing Escape in addition to Ctrl+D.
- Unknown shortcut combinations and unhandled keypresses are now relayed to the Rhino command line. So if you type "line" while Grasshopper is the active window, it will start the _Line command in Rhino.
- Objects can now instantiate themselves from IDs and Object Names, though there is still a problem with auto-updates.
- Variable parameter UI has been tuned up and all remaining (I hope) bugs have been fixed.
- Parameters and Components now have per-object display modes for icons, text or application default.
- Bakeable objects now feature a Bake... option in the menu which exposes more control over attributes.
- The Panel object now has an option for multiline input, which allows you to define a list of Strings simply by typing in multiple lines.
New Components:
- Params.Primitive.ID (represents a list of Rhino object IDs)
- Params.Special.Readfile (asynchronous text file parsing from disk with auto-update feature)
- Params.Special.ImageSampler (asynchronous image file parsing from disk with auto-update feature)
- Logic.Tree.ExplodeTree (extract all the branches from a data tree)
- Logic.Tree.PathCompare (compare a path to a search pattern)
- Logic.Tree.ReplaceBranches (a find/replace operation on the branches of data trees. Read the help topic of this component for information about how path mask work.)
- Vector.Vector.Display (preview anchored vectors in the Rhino viewport with an optional gradient)
- Curve.Util.Reduce (polyline reduction algorithm)
- Curve.Util.Rebuild (rebuild curves)
- Curve.Spline.CircleFit (fit circles between other circles)
- Surface.Primitive.SphereFit (create a least-squares fitting sphere for a set of 3D points)
- Mesh.Triangulation.ConvexHull (create a 2D convex hull for a set of points)
- Mesh.Triangulation.DelaunayEdges (create a 2D delaunay edge-graph for a set of points)
- Mesh.Triangulation.DelaunayMesh (create a 2D delaunay mesh triangulation for a set of points)
- Mesh.Triangulation.FacetDome (create a facetted dome for a set of points on a sphere)
- Mesh.Triangulation.OcTree (create a 3D Oc-Tree structure for a set of points)
- Mesh.Triangulation.QuadTree (create 2D Quad-Tree structure for a set of points)
- Mesh.Triangulation.Proximity2D (find the N closest points in a 2D set based on minimum and maximum search radii)
- Mesh.Triangulation.Proximity3D (find the N closest points in a 3D set based on minimum and maximum search radii)
- Mesh.Triangulation.Voronoi (create a 2D voronoi diagram for a set of points)
- Intersect.Boolean.TrimSolid (trim a Brep with any number of cutting objects)
- XForm.Morph.SpatialDeform (deform geometry based on a custom spatial definition)
If you're brave enough to test this, please post bugs as soon as possible on this forum since I only have 1 day left before I leave for Siggraph.
Enjoy!

Contenuti
Durante questo corso, attraverso l' uso di tecniche avanzate di modellazione Nurbs,
si potranno costruire modelli tridimensionali complessi che permetteranno di comprendere le tematiche legate alle forme complesse dell’architettura.
Particolare attenzione verrà data allo studio delle superfici a doppia curvatura, alle superfici rigate e alle superfici sviluppabili, quest’ultime adatte alla creazione di manufatti rivolti alla produzione. Allo studio delle superfici sarà affiancata la logica della loro tassellazione, quindi il passaggio da entità continue ad entità discrete, indagandone il valore attraverso esercitazioni pratiche.
Per comprendere meglio le finalità pratiche della tassellazione verrà adoperata una plug-in integrativa specifica per questo tipo di operazione: Paneling Tools. Le lezioni pratiche saranno arricchite da brevi comunicazioni teoriche utili a perseguire l’obiettivo della costruzione di modelli complessi. Sintesi programma

eded to calculate many Waterplane Areas and the GH Area component was bogging things down. I looked to Basic Ship Theory and the use of Simpson’s Rule which in this case mirrors an intersection between a Half Hull and a waterline and then divides up the enclosed waterplane into an even number of equally spaced segments to calculate the area. The result of which is 99.997% of the Rhino and GH area and about a thousand times quicker (more actually). But when checking my method I lofted the simple section curves and fed this into an Area component and had a result a hundred times quicker than the original. This got me thinking that it was the complexity of the Surface that was a problem so I rebuilt the curve with the same number of points as used in the Simpson’s Rule calculation… This was even worse now taking 4 minutes as opposed to 2.8. Wondering why, I realised that the original surface and my Simpson’s surface where created 90º to each other. One lofted from one side of the vessel to the other whereas the quicker method lofted along the length. So I swapped the UV of the original and low and behold 4.3s….
The methods, results and images of the different area calculations are shown below with Simpson’s Rule at the top followed down by: Simpson’s Surface, Original, Swapped UV, and Simplified at the bottom. Also I attach the Definition AreaQuestion.gh
It’s also interesting to note that Rhino Itself does not take anywhere near as long to calculate.
All achieve as fast as I can select a surface and right click
I know the Area component does a lot more than what Simpson’s rule can achieve i.e. 3D surfaces with complex shapes but it would appear that some sort of evaluation of the surface regarding the UV direction might speed things up or if there was a check for planar surfaces to implement a numerically faster approach such as Simpson’s Rule.
I hope this was all of some use.
Slaynt vie!
