Hi Daniel,
Had a browse through your great stuff and thought you might be a person that could give me some leads.
I want to make a tetrahedron based sound source (4 small ~2.5″ loudspeakers, one centred in each of the planes). In addition I want the loudspeakers pulled back into the body of the tetrahedron with the shape of the resulting surfaces to be minimal. I also want to be able to “flat pack” the sides to help transport (I need to be able to take this as hold baggage on a plane). My gut feel is to just use a linear connection between the loudspeaker and the edges. Cheers.
Hi Daniel
I’m impressed with your creativity and scripting ability. Do you happen to know any resources for Rhino which would enable one to do something like this: http://www.artlandia.com/products/SymmetryWorks/v4.html
but for 3D models/solids?
Thanks
John
Great stuff, Daniel, I plan to blog your 4D rotations, which are mind-blowing. I’ve always wanted to see something like that.
I’m glad you’re working with continuous-valued CAs, that’s a big interest of mine, maybe you’d seen my CAPOW program at http://www.rudyrucker.com/capow
Dear Dan,
I was bowled over by your presentation on tuesday.
I will struggle on with the origami star box.
Bravo and thanks a million for your inspiring lecture.
yours Penelope

Hey Daniel,
You made great comments on my site before http://digigami.wordpress.com, wanted to thank you. I was wondering if you wouldn’t mind helping me again. I’ve been working alot making physical models of the Ron Resch tesselated fold and now I wanted to make a digital one in grasshopper. Basically to do what the rigid simulator does but with more control. Any ideas on how to start? Thanks in advance and I understand if you don’t want to give away your secrets!
Glad I could help.
Simulating something like the Resch pattern in Grasshopper would probably not be easy.
In general finding the way parts of a folding pattern interact requires some serious computation (In fact I think I’m fairly sure its an NP complete problem)
If you’ve got the math skills you could script something in vb using numerical integration to find approximate solutions. It might also be possible to do something with a simple spring system.
However, if you can identify the underlying symmetries in the movement, there might be a simpler solution.
I am so impressed with your work. I am studying Human Computer Interaction Design with interest in using smart materials for dynamic product interface (which can change shape or texture according to different contexts of use). In this vein , your work on deployable/transformable surface is really inspiring to me.
It seems like that you used typical paper or cardboard for that work. However, it is really interesting that even the material properties of the surface look so different in the video clip that I am wondering if you had used special types of materials. Could you let me know of the materials that you had used if they are different from usual papers? That would be really helpful for my research without waiting for advanced nanotechnology to be available to designers. =)
Thank you for inspiring work. I really enjoyed them.
Hi Daniel, I am a week away from handing in my part 1 final project at Canterbury School of Architecture – I composed a project purely based on my take of Virilios oblique function – I have visited your blog previously as I work in Rhino and was learning some Grasshopper from you – but since I noticed your interest in Virilio I thought you migh be interested . Kind regards, L
Wow, I found this place on Google searching for something completely different, now I’m going to have to go back and go through the old material! So long free time this morning, but this was a great find :)
Hi Daniel, thoroughly impressive work. I am doing a study on real world folding tetrahedra trusses and i’m just wondering where i could find further information on the tetrahedra and similar folding trusses that you display on your vimeo video page. especially the first and last video segments?
Hi Daniel,
congratulations for your work!
Several years ago I was engaged in a research about joints for deployable structures to be used in extreme environments.
Do you have any link in which joints’ theme is examined deeply?
All the best.
Luca
I am experimenting with a deployable structure idea. I have Rigid Origami Simulator. Can you tell me how you produced the movies you’ve made with this? I can only seem to get it to advance frame by frame.
I’ll share the file when I’ve got something more complete.
Hello,
I realy love your website, especially folding.
It’s a very good inspiration for personal and design works.
Here you can see an animation I realise for an art school work by a folding I find on your website : http://vimeo.com/7650070
I hope you enjoy !
Arthur
Ps : Sorry my english is so bad, I’m ashamed…
Ps2 : I can’t export neigther in bitmap neigher in “.obj” with RigidOrigami, do you know what is the cause of the problem ?
Thanks.
Hello Daniel,
excellent work with parametric tools.
You mentioned that you completed RIBA1 at AASchool. Have you learned all that scripting skills there, or besides AA program? I’m attending AA at autumn and would like to know your experience.
Thanks!
I understand that Foster is using some GAs in the early design phase. Is there any truth to this? If so does he actually use the genetic process for design or simply run the algorithms until he gets something that he wanted anyway?
Hy Daniel! I used a picture you put in one post to build some origami models. I’m graduating in building engineering in Rome and trying to build a deploybale structure origami inspired.
Only now I discovered you work in Arup, that is where I would love to go. Hope my thesis will help with that.
Thanks for everything.
Luca.

Not sure the best way to get in touch with you so sorry for bombarding the forums etc with the same sort of question!..
I am using Rhino V4 and the last version of Grasshopper to work with it. Using these, I can only get kangaroo version 0.084 to install and work.
Is this likely to be fixed, or am I just stuck with this version?
I REALLY want to try you develop-able relaxed mesh tutorial as it could be the exact thing I am looking for in order to make some membrane structures etc.
PS, if you ever need any CAD cutting/plotting done for free (within reason!) on our 7 x 1.7 m table, I would be happy to do some for you in thanks for your amazing software!
Many thanks and keep up the amazingly inspiring work!
Thanks for a marvelous posting! I really enjoyed reading it, you
happen tto be a great author. I will always bookmark your blog and will eventually come
back in the future. I want to encourage you too definitely continue your great writing, have
a nice holiday weekend!
Hello,
Your work and research is truly AMAZING. I discovered a demonstration of paper structure by you on Vimeo. I am a student at the Montreal’s school of design and i would be grateful if you could share the 0:22 seconds pattern. In any case thank you for sharing your work ! You can reach me trough aragones_1@hotmail.com
We working on a egg shape in Rhino and want to fill the surface with a diamond pave in a perfect packing circle. You create the perfect solution for it (see: http://vimeo.com/74748879).
Hi Dan! I would like to quote “Rheotomic Surfaces / Space Symmetry Structure” Journeys in the Apeiron for an academic paper. Can you provide me the correct information, the date you wrote the paper and if it was published? I need this ASAP, AKA yesterday.. =) Very beautiful work!
Miguel
Thanks for sharing your wonderful work! I am in particular interested in your circle packing driven by an image. Is there a way for me to write a java program to do that?
hi there. I am also hoping to be in touch with you. I am working on a new art project that looks to invert meshes of interior rooms derived from scans for a series of video works and sculptures. I’m looking to hire someone to help, but I’d mostly just like to discuss the feasibility of this with you. Thanks!
Hey Daniel,
I was wanting your feedback on something and was wondering how I might get in touch with you. I couldn’t find your contact info anywhere on this page. It concerns a hyperbolic paraboloid construction toy that I have developed and had thought that it was a minimal surface area. You write that it is not, and I wanted to find out what I should call the saddle structure soap film that looks just like a hypar. Is it a hyperbolic catenoid??? If you’re interested, here is a link to the Kickstarter campaign I ran back in May of 2021. I think you’d get a kick out of this toy! https://www.kickstarter.com/projects/hypertile-toy/hypertiles-an-adventure-in-hyperbolic-exploration
