cript is quite large for a lack of better understanding of the program.
The idea is that we created a grid as you can see on the script, in this grid we then place pegs, we find the center and then create a radius around the pegs for the robot to not hit the peg but pass around them, we created a divide component to divide the circle in a maximum of 6 points in order to alter them and edit them if the thread is getting to close to the peg, here is were we encounter the first issue. If we change the number of divisions less or greater than 3 ( the default ) we have to weave everything again and add the extra points.
First Question, Is there a way to tell the component to always weave from 0 to the last point on its list independent of how many points it had? Meaning it goes 0 then 1 then 2 then 3 if 4 points, or 0-1-2-3-4-5 if it has 5 points.
The second question is if there is a way for the weave to always go when in its own list from 0 to max, but if its trying to weave with another list then tell it to weave between 0 and 2 but the closes 0&2 always so it does not try to cross the pattern.
----------------------
A last question but not as important, we created 4 pegs and made the script for them but lets say we wanted to add 1, 2 or 3 pegs more, is there a way to make the script more optimize as to not have to go back and re make every component/weave too include the extra pegs.
Uploaded are the 3D File ( Excluding the Robotic Files/Components ) and the GH File, I will try to upload a couple of drawings if nessesary.
Current Issues:
We used a Circle to create a radius around the pegs, and then depending on the division of this circle we then weave through it and across to create the weave polyline. This points are then sent as planes as the robot only understands planes for it to follow. The issue is that if we increase the number of divisions it breaks the weave pattern.
It seems that we weave is only 2Dinensional for some reason and it does not goes to the next level once it completed the level below, meaning its only closed loops instead of a single loop.
If we add more pegs than the 4 original, it breaks the pattern and we have to remake modules for every single extra peg and then remake the weave, Is there a way to make this faster/more elegant?
Our current trial is a simple stack weave, later on we would like to try bending the pegs in different ways, heights to make the weave more interesting but for now we are trying to understand the more optimize way to make the first step stacking work and then jump to a more complicated form.
------------
I place a Create Geometry Section in the script, the idea is that one could Move/Alter the Pegs and create different shapes and this would update/optimize to the best weave, but as of now all it does is it wither breaks the weave, or crosses in the center.
Changing the Divisions of the Circle breaks the weave, as of now there are 3 Divisions and the weave goes 0-1-2, but if you increase it it would not go from 0-Last Digit, but try to find 0-1-2 and weave incorrectly.
Any help is appreciated. And if there is a better way to do this, Please do not hesitate to edit the script, I will then follow the changes to understand them.

between internal structural frameworks and non-bearing skin elements, this approach promotes heterogeneity and differentiation of material properties. The project demonstrates the notion of a structural skin using a Voronoi pattern, the density of which corresponds to multi-scalar loading conditions. The distribution of shear-stress lines and surface pressure is embodied in the allocation and relative thickness of the vein-like elements built into the skin. Its innovative 3D printing technology provides for the ability to print parts and assemblies made of multiple materials within a single build, as well as to create composite materials that present preset combinations of mechanical properties.

and the degree of your periodic curve is 3, then start picking one point to the left. If the degree is 5, start pickin 2 points to the left, etc.
Every curve has a domain. A domain is a numeric range defined by two numbers (a lower and an upper bound). Within the domain, the curve exists and the equations which govern the geometry of the curve yield decent answers. The lower limit represents the start of the curve, the upper limit the end of the curve. Everywhere in between you can evaluate curve properties (position, tangency, curvature and any other derivatives, tension, torsion etc. etc.).
There is no significance attached to the actual numbers in a domain. All that is required is that the lower limit is smaller than the upper limit. When we create curves in Rhino we tend to pick domains that represent the length of a curve, but if you scale a curve afterwards you change the length, but not the domain.
Curve parameters are numbers inside this domain. Basically, think of all curves as finite line segments which can be bend, kinked and stretched in 3D space. Curve parameters are locations on the 1-dimensional space that is defined by the line. The curve equations are all about converting those one-dimensional parameters into three-dimensional points and vectors.
Like I said, the mathematics are pretty involved and periodic curves are more difficult still.

mber of ways, and how they are represented will dictate the final outcome.
2)If you use rectangles a question for area would be how do you dictate the ratio between the width and length? It may be easier to use circles or rather simple points with a specific charge attached relating to required area, think of the metaball component in 2d or using an isosurface in 3d (I recommend Daniel Piker's Aether plugin). So do you want something orthogonal or more amorphous?
3)Means of creating adjacency: I think for the best results you will want something that operates recursively. Hoopsnake, Octopus, Loop all allow you to create your own recursive loops, however, you might find that using something like circle/sphere packing within kangaroo will give you the desired results. In the case of Kangaroo, the spheres can be given different volumes and the connective network treated as springs to push and pull things together.
4)At this point you will have your basic geometric relationships, start simple and build up. You will want to go back and embed more intelligence into the script pulling in new parameters and inputs to relate to the given context (orientation, sun angles, topo of site, vertical arrangement, circulation). Here you may add new forces to the kangaroo to create a repelling force or attraction to certain areas.
5)Once you have this all in place it is time to flesh out the model, floor plates, partition, aperture, etc. This can be done strictly in GH native. Your primary challenge is establish believable connection between the recursive solver and the forces and output, not an easy task, but very doable.
Good luck, …
ual not tactile. i havnt touched the roof of my house i have been living in since 25 years yet its a part of my space. its still a visual plane between me and sky ( except that it protects me from rain). anyway, the point was to reconstruct huge cathedrals without moving big amount of earth.I came up with Nuun lense ( i had in sketches, it will be shorter form of this ugly cube, probably in mms) which will line the necessary floors and stairs-wells and towers.
During my experiment I realized this can be used for visualizing architectural spaces in real time, specially for arch student, it could be used as a console, that can replace cad and other 3d softwares. you can draw basic grids, orthogonal shapes ( not Zaha hadid stuff ). I still am very enthusiastic about this idea. I want to see it function some day.
Grasshopper was used to drive poor reflectors through firefly, to bend laser.( it failed badly) Its just for idea if anybody likes to follow, i dont have enough resources but it would make me happy if some day i see students working on realtime laser models and building having virtual ornamentation.
Any architecture/ electronics student who wants to further his research in lasers and its application in virtual modeling can contact me.

ive input but I have no clue how to begin doing this. I've read about using Processing and have even tried something with Processing but it didn't work for me.
I haven't had any luck finding step by step tutorials on inputing data with the 'read file' tool either. I have a feeling that just knowing how to import data would help a lot but the only examples I've found didn't work for me.
I'll be honest though, when it comes to programming and code, I'm an idiot and at a very beginner level. However, once I have working code to study and play around with, I pick up pretty quickly. I've done this with some of the GH definitions I've found and had some good results.
Basically, it's been very difficult and frustrating since I've spend literally 4 weeks trying to figure this out. Like I said, I'm not good with code! Fortunately I've had a little bit of help from the GH community and am very thankful. With any luck, maybe some other people on here would be willing to help out a couple students working on a thesis project? We don't have money but could exchange fabrication services for your help with code or definitions. We have access to a 3 axis CNC mill, Laser Cutter and FDM printer.
Thanks for your time (and hopefully your help),
Matt.

to problems. If anyone wants to take a look at the attached file "605b-3" and try to help me, that would be awesome.
The way I'm thinking about creating the louvers:
1. Contour the shape (could be any shape, but I attached the one I'm trying to do it to)
2. Divide those contour curves
3. Find the 4 points on those curves that are furthest away from the center of each curve
4. Move those points slightly away from the center of each curve
5. Replace the unmoved points with the moved points
6. Interpolate/NURBS curve through the new list of points
7. Loft the new curves with the original contour curves
I think I'm close, but I'm getting stuck at the end- I thought shifting lists would be the best way to solve my problem, but I'm a little confused as to how grasshopper is organizing the list of new curves and how to match that organization to the original curves.
Attached is an image of where I am stuck. I can only create a surface in the gap that I'm trying to create by the louvers. Either that, or one or two of the curves tends to create a "tornado" looking thing and i can't figure out how to fix it without individually breaking up the list. Is there a way to set all the curve seams to be at the same location in a list?…
ry branches would be an added bonus.)
I had an idea of using contours to find the center point, then connecting these found center points to create my centerline. However, I am facing a few challenges... specifically, I do not know how deal with splits in the tree branch.
I think I have an idea for how to deal with this, but I am not skilled enough (yet) to execute. The whole idea would look like this:
1) create a list of contours through the tree branch
2) connect the center points of the contour lines
3) when a single contour produces two separate polylines (when the tree splits), AND the previous contour produces only a single polyline, divide the list into two new lists starting at that contour.
4)when a single contour produces two separate polylines, AND the previous contour also produces two separate polylines, draw a polyline between the closest pair of centroids.
Has anyone run into this (or something similar) before? And, is this a good way of going about it?
The attached script is incomplete, but has the oak tree branch internalized.
I have been struggling hard with this....Any help would be greatly appreciated!!
Thanks,
Ethan

flat) and then subdivide your surface using the divide domain component and feed that into a surface box. Your base geometry, base geometry bounding box and surface boxes will all drive the box morph.
From the looks of your geometry, it appears that it is designed to nest in a particular way that isn't strictly rectilinear, but is more staggered, so that the top corner of one element fits into the bottom corner of an adjacent element. You can achieve this using the box morph, but you have to get pretty creative with how you subdivide your surface:
I'm attaching a couple of files...first of all is your definition with the changes in it to make the above. But also I used some components that I made recently (will release them in a package with a bunch more hopefully soon) called tree sloth, which helps manage data trees and lists. I used a couple of those components, so I'm also attaching the gha for those. Just copy that file into your components folder (under file-> special folders) and restart rhino/gh. The new components are just layered into different parts of the "Sets" components.
To explain what I did: you basically you want to have adjacent sub-surfaces along your guide surface to overlap at the top and bottom thirds. There are any number of ways to extract these surfaces...I just pulled out strips in each column and culled every fourth element, but shifted by one in alternating columns. So in the first column I take strips 1,2 and 3 and skip 4, take 5, 6 and 7, etc. and in the second column I start at number 3, 4, 5 and skip 6, then take 7, 8, 9, etc. Then I collect each of these batches of three strips and take the bottom left corner and upper right corner UV domains to create the target surfaces for the morph.
Hope this helps you out...…

Architectural Animation_ Designing National Cyber Games Center in Tehran by Using Digital Architecture Findings
Game is one of the oldest human behaviors and it is specifically related to the culture and region in every society. Considering the change and growth in societies, they –the games- coordinate themselves with these changes. Inventing digital tools, games entered a new arena and quickly changed to a remarkable area in industry and economic market and they also attract more time and audience towards themselves, not requiring big and special spaces, being accessible to public. Regarding the extensive effects of computer games on economic, cultural, educational, physical and mental health arenas, every country has done a deal with content control, supporting producers, increasing public awareness and etc within its special background. Iran computer and video games foundation as a non-profit organization takes charge of different domain support and control in this effective industry under the supervision of Ministry of Guidance. Architecture and computer games in different domains have influenced each other and are interconnected. And since games are played in one space, they require game space designing together with type of the game. So game designers need knowledge and studies in architecture design. Architecture, inventing digital tool, used its features to advance its goals, as games did. Although at first it used them for drawings and visual expressions of ideas, extending these features, they were used in design process. Meanwhile, using digital technics produced specifically for animation making and computer games leaded to their more proximity. In the design of Iran computer and video games center, we tried to use digital features in all steps. Therefore extracting main parameters from the designing process steps and changing them to computer codes (using algorithm), we tried to make its various states producible and to provide the possibility of optimizing the required area, maximum vision to key spaces around the site and also the amount of received light. Also in designing the project facade, after research on various technics of exfoliation and façade design, Media façade was used for a better compatibility with video games. With an approach to creating mobility for the audience and the computer game producers in the greenbelt near the project, physical playgrounds were created for them.…
