The Origami Forum

Well as I should be sleeping I decided that my first post should be put out there as I am only semi-lucid. I've spent a bit of time looking around and am amazed at the quality of human figures and design on this site.

I dabble in a bunch of stuff, such as, tessellations, boxes, bill folding (for a short interim), and 2d modulars (also a short interim) I have a blog at http://cedison.wordpress.com
and post on flickr http://flickr.com/photos/christine42/se ... 475462625/ The primary pic is an example of what I am referring to below.

****I am fascinated by taking apart and collapsing constrained paper with a given polygonal base. Sorry I don't know how to phrase it better. Does anyone know of resources that would help me understand collapse constraints. A lot of lovely people have given me avenues, but topology books I've been referred to have no relationship (I think). If you know of someone, especially in the origami field, or some resource that would help me understand my hobby I would appreciate the heads up.****

Thanks.

Sincerely,

Christine Edison

First off, welcome to the forum! I have seen pictures of your work, and it is very impressive!

I am not primarily a tessellation-folder, so we may be speaking in different terms here, but...by base do you mean a preliminary step in folding a model (as in bird base)? And by collapsing do you mean flat-folding (I am assuming yes since you say polygonal)?

If you are talking about flat-foldable bases that become models such as human figures, then my suggestion to learn more would be to read Origami Design Secrets by Robert Lang. I learned just about all of the theory behind designing that I know from that book.

I may be talking about something completely different than you, so I apologize if I misunderstood you. Again, welcome to the forum!

Hi cedison,

I have seen your work on flickr....its awesome!!!

The first thought that came to me when i read your post is....you want to fold a large sheet of paper into a tessellated base, parts of which can be physically pulled up to make a skyscraper or tower and another part of the same paper be modified to make perhaps a lawn or some vegetation etc. If what i am saying is right, then maybe you should have different tessellation patterns on one sheet of paper so that you have a sort of pull-up scene, maybe a Pagoda with a rose garden around it.


I too apologize if its not the correct interpretation

Regards,

To both thanks.

Paperz-you are thinking somewhat in the same vein I am. Jonnycakes, thanks for replying but what I am actually looking for is 3d collapses. I take a gridded paper and create a "net" that constrains/holds paper and then pull some out and recollapse.

Spiral 3d collapse-How to predict height by angle rotation, sample question





Non spiral 3d collapse



Rotational limitations



Sorry to picture dump, but they might explain what I cannot.

Thanks-I think I get what you're saying now. I really have no experience in that area, though-I mostly fold representational origami.

Hi Christine

This might not be exactly what you are asking for but it might help you. Philip (Oschene) has worked a lot for many of his models, specially the Compass Rose ones, on the topic of angles that allow collapsing of models depending on the number of sides they have. He and I discussed the topic a while ago and he said he is no mathematician (sp?) but he knows about it, I can attest to that.

Maybe you could ask him
