Anyway, if it is possible, please review my grasshopper file and let me know if I made any mistake or missed some problems.

Thanks! and See you tomorrow :)

It takes so long time to finish running Galapagos and Ecotect and I captured some process. I'm not sure if my definitions are all correct.

Please review and let me know if my definitions are incorrect and I missed some requirements.

I'm so sorry that I have to miss the last class.
I learned a lot about Grasshopper and Galapagos and I really enjoyed the class.

Thank you very much.

Please follow the format described here.

Some notes:

1. You must use Vimeo or YouTube to post the video. Please do not upload video files to this wiki as space is limited. Going through these sites will also allow you to embed the video file directly to the wiki page.
2. Final projects must be submitted on time to this wiki (no later than Thursday 6:00 PM). It will be considered late if it is after that point..
3. Uless you have already received my pre-approval, all students are expected to attend the discussion review at NBBJ. This is a key part of your participation.
4. I will be selecting certain projects for discussion tomorrow. I will contact you in advance if I have selected your project. Be prepared to share describe your project to the group.

Please post any general questions about the final submission here (Format, schedule, etc)….

Also looking at the "program.ghx" file i am not sure how to change the desired area quantity there are two panels one on the very far left that can be edited and the other on the far right that states "Desired Area" that can't be edited. I understand how both these definitions work I need help bringing them together. Any help would be awesome. Thanks.

It would take long time to run Ecotect and I want to confirm my all definitions are correct before running Ecotect.

Please let me know.

Thank you.

I also tried to apply the ecotect definition to my grasshopper file, butit has same issue with Myboon-weird geometry on Ecotect Screen.. is it ok?…

I wanted to have three different objectives for the optimization of my building; Minimize total facade area, Maximize south facade area, Minimize solar radiance via ecotect analysis. When I run this, it took time forever… I guess it is because of too much slides and definitions are going on this file. How can I develop or refine this more?

Please take a look and give me some advise! :)

how do I generate random but-not-really-random points on a 2D surface by using grasshopper components? i am trying to model a facade skin like the Water Cube pattern… i like the points generated by sphere cloud, but its on a 3D surface…

Thanks.

Simon

Has anyone try out the CamStudio yet? I did that this evening, and would suggest to you to give it a try asap. - Simon

I built a logic of maximizing south facade area as one of my multi objectives and got some problem when I tried to make polylines as planars(option#1 in the file). Therefore, I used 4point surfaces command(option#2 in the file) and it worked. I don't know why the polylines -planars logic didn't work out.

I uploaded my files.. If you guys have some time, please look at it and give me some clue for this issue.

Thanks!

Simon

With that said, here is what I'm attempting to do with this TriGrid…

1. Control the total number of equilateral triangles that will compose/fill a rectangle of defined area. Right now I only have an integer value for number of triangles in the X and Y direction (I don't know how in Grasshopper to even define the area of the rectangle yet (read: my building facade) - but I know what dimensions I want for it, which will need to flex/change so that I can solve for multiple facade areas). So, I'm assuming that one would start with how to define the rectangle/bounding area itself and fill it using the TriGrid component which would be defined/divided up somehow to control each triangle individually.

So, for example, let's say I had a 100' x 75' rectangle and wanted to divide it into only 25 equilateral triangles, but the triangle edges could be of any integer lengths between 1 and 10 so that you wouldn't have this even grid of triangles but a 'random' collection of triangle sizes. Then, run Galapagos and see what the solutions look like and again for multiple 'numbers' of triangles (25, 50, 100, etc)

2. Take the problem above and now suppose that you give priority to only one side of the rectangle and define that only triangles of sizes 5 through 10 can touch that priority edge.
Run this for multiple 'numbers' (sets?) of triangles (25, 50, 100, etc).

3. Take the problem above and define that one triangle of each length 1 through 10 must touch the priority edge. Once again, run this for multiple sets of triangles (25, 50, 100, etc). It would be great to mix this up and say that two triangles of length 5 must touch the edge and four triangles of length 8 must touch the edge, etc.

4. Same idea as above, but add another layer/(fitness?) to those iterations that have the largest (or smallest) triangle at the midpoint (or maybe endpoints) of that priority edge.

5. If I can get to there, I'd like to model four sides concurrently, so that the edge condition between two faces is now the priority. In other words, say that one face is modeled for question #2 (of the above questions) and the other face is modeled for question #4 and the fittest version is the one that has the fewest (or most) triangles on that particular edge condition. I'm content to Bake/Photoshop these 2d rectangles together to make up these scenarios as it might just prove too processor heavy to combine everything into one model. But I think that's the final project right there.

If anyone can spell out just in a sort of (use this component) > (do this/use this component) > (etc) for me I would be really grateful. Thoughts?

I would like to know how to divide only 2 surfaces of the box.

I am thinking of high-rise building consisting of 4 bundled tubes with braces for my final project. Two surfaces of each tube face other tubes and only two surfaces of each tube have braces.

How can I select only 2 surfaces (for example south and east facade) and divide them?

Find the dimension of the trapezoid of greatest area that can be inscribed in a semicircle of radius r.

1- Go to your personal lab page. At the bottom, you will find "files" tab. Go to this page and upload the image you want to show on your page.

After you upload all the images you want, right-click the image you want and "copy link". Then, go to "edit" at the bottom of the page.

You will see an empty space in which you can type in. Type in the line underlined in blue in the image. Replace my image link with your own link.

I hope this helps!

In my studio project this semester I am using Processing to generate lines for structure and surface. These lines I am then importing into Rhino via Grasshopper and piping them according to their length (short lines are thin and longer lines are thicker). I have found that it is pretty simple to do this using Grasshopper but it produces some pretty clunky geometries. Since the piped joints are separate and each radius is different they do not transition smoothly. Ideally I would like each line to recognize its own length as well as the length of it's joining lines so that they can taper toward the joint and resolve at a common radius. Any suggestions or examples of similar projects would be much appreciated!

I have uploaded my grasshopper file, the necessary text files and a few images of the geometry on my lab page.

Thanks!

• Formatting data using expressions
• Streaming to external files (txt, csv)
• Laying out geometry using planes and orient components
• Labeling using tags.

See you all next week @ NBBJ for an office tour and Grasshopper Summit

Do you suggest beginning with a basic panel system and swapping out the distance logic group with the sun system file?

Thx
Kelly

Grasshopper can stream information to different file formats that can be read by Excel. However, to get information organized into an excel spreadsheet requires some scripting…

Enter LMN Tech Studio's custom Excel component which allows you to create organized spreadsheets based out of Grasshopper….

NICE!

I have started my own page… some of you may want to consider using it as a template. I am using tables to organize the page and keep my files organized. Tables are quite easy and can really clean up the look of a page.

On another note, take a look at the diagrid and space truss files I have posted.

The topic article will be a summary of the techniques and concepts introduced in class.

Most of the materials (if not all) are already available throughout this wiki and in our weekly tutorial files. Your task is to organize the process into a clear summary.

The groups will work collaboratively to….

• Define the topic (as it relates to our class)
• Provide diagrams and images explaining the topic.
• Organize and link to Grasshopper files related to the topic.
• Organize links and reference materials (other websites, blogs, etc)

For an example of a good topic article format, refer to a Wikipedia entry such as Architectural drawing

Creating responsive systems as a way to establish feedback between an external "influence" and system of objects (panels, surfaces).

Topics covered in Week 3 Files

Point-based attractors
Curve-based attractors
Image mapping
Responsive surface
Responsive panel
Introduce nGai's sun systems.

Assignments

• Exercise 2: Solar Responsive Panel System
• Test concepts on parametric skyscraper
• Seminar Topics Article Progress

PS Everyone seems to be doing a great job keeping up! I know this is challenging stuff…

I thought maybe that meant the file was corrupt so I uploaded it again, but still it doesn't work…

suggestions?

This builds on the tower definition we assembled together. There is nothing new here that we haven't gone over in class…… look closely at the JPEG….

I will post my file when there are a few attempts or responses.

Remember, I expect to see some tower-related ideation/evolution on your labs page by next week

Have a good weekend!

Questions to explore before next week…:

1. What are the possibilities for creating new programatically-driven tower forms?
2. What is the relationship between the the tower's program and its structure and skin?

Check out this website: http://www.digitaltoolbox.info/grasshopper_basic.html

It has some nice tutorials!

Any ideas?
