What I figured yesterday is that the increase in radiation because of the reflective facade for the 'worst' month is only about 2-3 kWh/m2 as your looking at a value of 80 without and 82-83 kWh/m2 with reflection.
So my assumption is that the glare factor will play a much bigger role instead of intensity of the sun, looking at comfortable levels. So I'm looking in this as well. It's very cool to play around with these plugins and see the outcome. I'll keep you guys posted.
@ Claudio, that was exactly my problem as well. I presented a direct sunlight hour analysis, to show the increase in direct sunlight hours because of the mirrored facade and at what times of the day the reflections occurred. But it is hard to asses if this is 'bad' or 'good'. The restaurant in question receives more or less 130 direct sunlight hours 'naturally' in the worst month and because of the reflection the result was 161 direct sunlight hours, but the client was like okay..... and is this a problem? So we decided to look at sun intensity but I didn't want to fall into the trap of in the end presenting kWh/m2 and having the same problem not knowing if this is 'comfortable' or 'annoying' etc. Good luck with your study, I'll post my findings
Thanks again guys…
nitions prior to Karamba are to allow the genes to manipulate the form of the shell and then kangaroo to relax the form to its "equilibrium" state.
The definition, as attached, runs fine over one iteration. However, when I run the Galapagos solver, rhino slowly uses up my computers memory and then ultimately crashes (around 80 Galapagos iterations). I don't think that the surface patch, or kangaroo are the issue, as I have run other iterative definitions through them without issue.
I believe Karamba may be occupying memory each iteration that is not released when a new iteration begins. This problem is exasperated by the fact that I am running 11 load cases, 9 of which are point loads defined over each vertex of the mesh. I ran a definition with only one load case, and it reached 170 generations (with a population of 50 for each generation). However, at this point it had occupied 90% of my computer's available memory.
Do you know of a way to ensure that Karamba purges its memory after an iteration, or is this a possible memory leak bug?
Thanks again, any help you can provide is much appreciated.

I think i'm about 80% there. It may not be the most elegant procedure, but it appears to be working. I am having some slight problems.
1. I'm having trouble extracting the edge curve on one side of my mesh
a. I used a mesh plane intersection to trim my site mesh, and the resultant curve extends beyond the limit of my mesh
b. I identified the intersection point, but GH is not shattering on that intersection point. instead it happens at a point further down the polyline
2. I'm can't join my curves. If i bake them, they join into a closed curve.... GH join curves is not behaving. i've had some success joining two segments, but i can seem to get all 4 side wall curves to join.
if anybody could offer some advice, i'd be very appreciative. also, i'd like some recommendations for ways to streamline this definition. I'm sure that there are more creative ways to manage this data, and i'd love to about them. thanks - CSDG

use an attractor curve to adjust curves that are being lofted to create a "wavey" surface. I've attached a picture to show the end result. Right now i create all the curves and then loft them together to create a surface which could then have a rib definition applied to it, and it works, my problem is that this project is for a 80' section of wall with ribs that would be a few inches apart, so that is a ton of curves i have to change everytime i want to adjust the overall shape. So is it possible to have an attractor curve that instead of adjusting the spacing of shapes in plane with the curve, would create high points or low points perpendicular to the curve? Hopefully that makes some sense, i'm having trouble finding the words to explain it, the attached pictures should help.
Any advice on how to do this would be great. I hate being that guy but this project came up last minute and it seemed like something the Grasshopper help save a ton of time in as far as adjustments go.
Thanks,
Kyle

h kangaroo and have found one project that illustrates my idea exactly...
https://vimeo.com/88002087
So far my best attempt has been to use a gridded surface in which the lines of the grid are springs, with a rest length at 80% of their initial length. (call this grid A) This is to simulate as if the material has been stretched 120% of its resting dimensions.
I have been trying to anchor the springs to a secondary grid (Grid B, curves that will be deposited onto the material) at the points of intersection with grid A.
I am not sure if this is the best approach, maybe soapfilm would be better? although i require the boundary (grid B) to adapt also...
Any advice or attempts to explain how Taichi Kuma has done this in his video would be greatly appreciated.
Thanks…
A: Who created it? / Copyright?
B: Anyone have a larger resolution copy of this image (or a vector so I can do a large resize).
Long and short - I'm an artist and I'd like to make a quilt out of that image. I need a decent resolution copy of it so I can do a huge resize and get a 76" x 80" crop out of it. I've tried resizing it in Photoshop, but by the time it's large enough, the quality has dropped below what is usable for my needs.
Thanks in advance! I totally understand I'm relying on the kindness of strangers here. (Also if this is inappropriate to post - please delete. Thank you)

can be found in "C:\Documents and Settings\<user name>\Application Data\McNeel\Rhinoceros\5.0\Plug-ins\IronPython\settings\lib\rhinoscript" folder on WinXP. So could have used yours too.
RhinoCommon is a SDK and basically the power behind grasshopper and rhinoscriptsyntax functions. In fact each time you call a rhinoscriptsyntax, a RhinoCommon code gets executed.
And, yes:
import Rhino - imports RhinoCommon
import utility - enables importing utility.coercebrep() (or coerce3dpoint() coercecurve() ... so on)
Item access means an input is consisted of a single item.List access means an input is a list.Tree access means an input is consisted of a tree with data on different branches.rs.BooleanDifference requires both of it's arguments to be lists, so it would be logical to set the inputs b1 and b2 as lists. But there is one problem, that Mitch pointed out to me: it seems that python components (like grasshopper components) are "intelligent", and can distinguish whether you are inputting item, list, or tree. Setting your input as list, might disable this ability and leave you with only possible type of input (list).So honestly I do not know why in this case, setting the inputs to Lists worked - due to mentioned "intelligence" of python component, even an Item type would work.This might be a question for an experienced user, I am just a beginner.…

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

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.
