Invisible Narratives - Weaire-Phelan Tesselation by GeomGym

Invisible Narratives

Adaptable Futures has recently launched the winners of their competition. We would like inform the group that our project is short-listed, which is designed by means of sdrTesellation tool of GeomGym in Grasshopper.

The design looks for a new brick topology which is in the shape of two generative elements of Weaire-Phelan structure; dodecahedron and tetrakaidecahedron. An innovative approach is taken by applying varying types of solutions and details to the new brick elements.

There are other good examples and winners which are worth looking into. Our sheets can be downloaded from here.

All comments appreciated.

We would like to thank Jon Mirtschin and anyone who contributed to this tool.

Congratulations to you both. Very impressive work, and always nice to see how others put the tools to great use.

Actually, we attempted to connect individual dodecahedrons (wooden) together by finger joint connections on edges. But we couldn't achieve this in an easy way in grasshopper and we were about waste so much time for this.

We are still wondering if there is any possibilities for the tool of GeomGym to provide such an option. This is just a question no need for a detailed explanation. But the suggestion we would like to hear is how to join the edges in this way with other tools such as the one discussed before.

The latter might not be having an interest for here but thanks for any ideas in advance.

Good work! the project looks very interesting, congratulations on getting shortlisted :) i love your panels.

I'm working on a similar idea, using WP to pack a volume and form acoustically treated surfaces for a uni project, and would love to look at your definition, if at all possible?

(i am also waiting for Jon's license for his StrucDraw plugin)

We have to construct the module for an exhibition, possibly out of foam (aranda\lasch style), timber and/or cardboard. will post up what we come up with.

Looking forward to hearing from all of you,

Fahimah

Hi Fahimah, thank you for your reply.

It sounds challenging to take acoustic effect into consideration. How can you do that? Is there another special application for acoustic effect analysis?

It is no problem to share our definition with you. But I dont have it on this computer. We will post it soon.

Good luck to your project!

hey xue, thanks for getting back to me. looking forward to check out your definition.

this might be of interest re: acousting testing - acoustical shoot group

i am importing my rhino file into odeon and getting it evaluated there. haven't got anything useful yet, but im keen to test out how the WP structures perform acoustically :D

also, just an idea i had about constructing the timber modules : did you guys consider making yours using the boat building technique called stitch and glue? instead of finger joints, you use epoxy and fiberglass tape to seal the panels to get a waterproof connection. check out this wiki page.

cheers,

fahimah

Hi Fahimah, thank u for the reply and suggestion.

to be honest, personally I didn't know the stitch and glue. But what we ended up was a similar method to what you said. If you take a look at the presentation of the project, it's there. We wanted to achieve a bit more difficult one as a definition improving our knowledge in grasshopper. So, finger joints still seem more sophiticated. Also the idea was indeed to make the WP blocks more convenient to get them prefabricated. I admit that stitch and glue could make it more interesting though as we looked for something which can easily be understood by a casual participiant.

For your keen interest, I'd say that the tool in GeomGym is very easy to exploit. Have a look at the simplified version of the file. It is rather interesting to me. it'd be very useful to learn the reaction of WP elements for everyone. It could end up with an intriguing result actually because acoustic depends on anything inside.

in Edirne in Turkey, there is a mosque built in 16th century,Selimiye mosque. The architect used some elements (earthenware jars) at the bottom of the dome as he tried simpler versions on the mosques in Istanbul prior to this one.

do you want to use WP elements similarly, or something else?

we'd like to hear from you, good luck..

Hi Serder I like the board alot and it looks like you've done a good job putting this together.

I'm doing some packing with Tetrahedra and Octohedra and was looking at GH script for reference. When I try to open you WP script it tells me I need Picture Frame and Mesh Naked Edge to open. Do you know where these are from?

Hi Rafael, thank you for your comment and question.

Picture Frame comes with Weaver Bird. Just download it and get it work. Normally, you must be having Mesh Naked Edge under Mesh/Analysis. It might be because of the Grasshopper version you are currently using.

Nevertheless, we need none of them as the GeomGym component there makes everything about tesselation. The others that you lack are about translating breps following tesselation to meshes.

Good Luck!!

I'm using the most up to date version, do you have a jpeg screenshot of the definition to show where it goes? Looking forward to learn from your work.

I'm looking at the script. I see two hierarchies of structure, the one created by joining the 3d proximity points and the mesh resulting from WP bricks.

I guess not seeing your initial input points I'm curious about the relationship between the initial point distribution for Proximity 3D and the WP distribution. Can you tell me a little more about this?

PS I really admire how clean and simple your definition is.

Oh I found the Mesh Naked Edge. I was playing with the script and the had troubles with the Picture Frame mesh- it has no thickness and came upon Mesh Naked Edge in Uto's Mesh Analysis.

Points are important for the sake of our design methodolgy and contextual approach. Please take a look at the picture:The points are selected randomly inside the volumes already defined by the existing buildings on our site. In so doing, the shape on which the tesselation is done comes from this morphological generation rather than our intuitive design abilities.

You don't have to do all of these for a tesselation. But this was the approach we tried to keep on, involving our personal decisions as less as possible by using contextual tips.

I hope this helps.
