nal vector.(see pic 1)
Second: Holding an abstract mesh or surface with a 3D grid structure. Basically creating 90 degree vectors on an uneven surface coming out of the object, sort of like a cactus with a grid pattern. (see Pic 2)
Third: I think #1 answers this issue: when the lines hitting the rough surface go in two different grid directions, their intersecting points are too close together. Structurally these points can be united and the vectors would be reduced. Manually deleting these lines after being baked is currently the only option. It would be so cool if there was a mathematical arrangement that would connect points that are within a certain distance to one another. (see pic 3)

If I change the number of polygon sides to 8 the result looks like this:
Note that there are no missing rows with 8 sides. I've tried all the numbers from 3 to 12 and in general an even-number of sides results in no missing rows, but an odd number of sides has a missing row. And for # sides 10 - 12 there are 2 missing rows.
I tried all the options for the Offset object's Corners variable which is use to make the solid outside wall, but this has no effect. I also tried rotating the cutouts a little and a lot, changing their size, height, etc., but this had no effect either. So I'm stuck on how to eliminate the missing row of cutouts.
I realize this is a more or less cosmetic problem (no one will see the bottom of the printed part unless they pick it up), but I'd like to get it fixed before I publish the final design. The attached GH file has all the components used to make these images.

eries of ramps with slopes =< 10%.
Here's my pseudo-code:
1. Populate brep with random points
2. Sort points by Z values
3. Draw line from point '0' of sorted points to all other sorted points
4. Project lines down to plane of first point and cull all lines =< 5.7 degrees (10% slope)
5. Sort remaining lines by length and return line with the largest length (what I want)
6. Cull all points used to create lines =< 5.7 (step 4)
7. ??? now, I want to somehow pass remaining points from step 6 back into the loop and return the next curve that is: the largest length curve from all curves =< 5.7 degrees
I've attached the script
Thanks ya'll!

ry close to the screen (the model unit equivalent of a pixel deep). I am using the DrawForeground override to generate these objects...everything is fine, except that we'd also really like the users to be able to output high quality images directly from the viewport. Using the ViewPortCapture (either to file or clipboard) with higher scales can create some excellent images...but here's where we run into trouble.
The geometry that is created close to the screen through the Display Conduit tiles along with the resolution in the output image...so even though the rest of the model geometry scales up, the HUD geometry stays the same resolution but gets repeated in a grid (2x2 at 2 scale, 3x3 at 3 scale, etc.). What is interesting is any geometry created in the normal model space (say, a circle at the WorldXY) gets rendered correctly. I have also tried using the CalculateBoundingBox override, using bounding boxes for the objects drawn, but it doesn't seem to help.
I have picked up on a discussion over at the McNeel forums, but haven't gotten any guidance over there, and was curious if anyone here had any pointers.
thanks!…

nteraction in the design of an enclosed volume.
Revolutions have occurred through architectural history and vary widely in terms of design methods and fabrication techniques. Focusing on inspiring natural form‐finding techniques, AA Athens VS works towards producing a large‐scale interactive prototype that alters in real‐time the perception of interior space.
Technology and architecture are coupled for the third year in Athens with a novel agenda of transforming an enclosed area and creating internal contrasting city‐life characteristics that transcend the local conditions. In collaboration with the National Technical University of Athens, Cipher City: Revolutions explores participatory design and active engagement modeling and continues building novel prototypes upon horizontal planes.
The toolset includes mainly ‐among others‐ Rhino Grasshopper, Processing and Arduino platforms. With the completion of the Programme participants receive the AA Visiting School Certificate. In 2013, the design agenda of AA Athens will connect with the agenda of AA Greece VS in the city of Patras. Participation in both Programmes will allow for a more extensive learning experience through additional tools like Autodesk Maya, Autodesk 3D Studio Max and more.
Discounts
The AA offers several discount options for participants wishing to apply as a group or participants wishing to apply for both AA Athens and AA Greece Visiting Schools:
1. Standard application
The AA Visiting School requires a fee of £600 per participant, which includes a £60 Visiting Membership. If you are already a member, the total fee will be reduced automatically by £60 by the online payment system. Fees are non-refundable.
2. Group registration
For group applications, there will be a range of discounts depending on the number of people in the group. The discounted fee will be applied to each individual in the group.
1. 3-6 people group: £60 (AA Membership fee) + 540*0.75 = £465 (25 %)
2. 6-15 people group: £60 + 540*0.70 = £438 (30%)
3. more than 15 people group: £60 + 540*0.65 = £411 (35%)
3. Participants attending AA Greece VS and AA Athens VS | 40% discount
For people wishing to attend both AA Greece VS and AA Athens VS, a discount of 40% will be made for each participant. (The participant will pay the £60 membership fee only once.)
£60 (AA Membership fee) + (540*0.60)*2 = £708
Eligibility The workshop is open to architecture and design students and professionals worldwide.
Applications
The deadline for applications is 24 March 2014. A portfolio or CV is not required, only the online application form and payment. The online application can be reached from:

r visual programming tools in the games world. MS's Kodu, looks interesting. Kismet and Visual3d look even more interesting..... mainly because they are more 'interactive' or 'reactive', rather than DAG-based.
Seems like the evolution path for GH-similar apps is:
1. base 3d or CAD app based on C/C++ code.
2. Add scripting language interface
3. Add some kind of visual interface
4. Add graph sorting / propagation engine
5. Re-jig base 3d or CADD app to make managed/interpreted scripts run faster, multi-threaded.
6. Add dynamic typed language, DLR stuff
6. ....
6. Add constraints solver...?
7. Rebuild CAD display engine to be procedural at the GPU level?
Seems like there are available tools for converting scripts into some kind of flowchart. There are even visual debuggers. MS even has something called the 'Debugger Canvas'. Spreadsheet constraints.
Seems like the time is ripe for lots of new apps like GH.

For my project I want to make a sphere or spherical-like shape and pack it with circles of varying sizes. The circles all have to touch each other and thus on a point where three circles 'sort of' meet, there can only be three circles. This is shown in the second picture I have attached, a 2D circle packing made by Daniel Piker. So basically what I want to achieve is having the second picture projected on a 3d surface, that I can also edit. Also I would like to be able to change the size and amount of the circles that populate the surface. This means that I would be able to say 'there should be 30 circles with a radius of 2, 40 circles with a radius of 3 and 50 circles with a radius of 4, put them on this particular shape'.
As I've just started the project I haven't done so much research yet. What I have found is for example this Kangaroo definition of circle packing in 2D: http://www.grasshopper3d.com/group/kangaroo/forum/topics/circle-packing-definition?xg_source=activity
It is very beautiful and does exactly what I want to achieve, except that it is in two dimensions. I also have to say that I feel pretty confident working with both Grasshopper and Rhino, but not really with Kangaroo. I have used it a few times but not extensively.
So what I'm wondering is, how could I best approach this project? I looked into the concept of 'circle packing' and I noticed that it can be approached very mathematically. As I am an architecture student I don't know much about the math behind the geometry (although I do think it is very interesting) and thus I'm wondering if I will be able to achieve what I want to achieve. Also, do you think I could best approach the project in Kangaroo and do you think it is realistic for me to think I could finish the project? I'm just trying to see if I'm not going to try to tackle a problem that is very difficult to solve even for skilled mathematicans or something. Sorry for the long and perhaps vague read, but I would be very happy with any sort of input you might have on my problem!
Thanks in advance!

ectly in grasshopper (drawing a curve on top of a line with different angles), i did the curve shape in rhino and import it into grasshopper.
i'm having a problem where some of the sine curve shape can orient or map onto the triangle surfaces nicely, but some of them do not. whenever i try to orient the shape onto the bottom portion of the icosahedron, the shape becomes 'negative', forcing me to flip the lines before offsetting and patch (i am using loft method) or else it will become a weird loft (image 3).
i have tried several different ways to orient the ones that worked (orient 3d in rhino, rotate 3d etc.) and still could not get them to work.
the reason that i want them to face in the same direction is so that i can use WB thicken and make sure they extrude in the same direction. i have tried to unify the normal faces in grasshopper and still it is not working.
does anyone have any idea why or how can i do this? your help will be greatly appreciated. i am fairly a beginner in GH so if there is any other easier method to do this will also be great :)
