Diagrams for geometric folds

Postby Anine » September 28th, 2004, 7:01 pm

Hi!

I'd like to know where I can find diagrams for the following models (books, internet, magazines?):
The 2 I uploaded in the BOS04 folder.
And several from John McKeever's page/photoalbum (already mailed him about them, but no reply):

Hi Anine. Seem to run into you everywhere these days...

I can help with a couple of these. According to http://www.origamidatabase.com, Jeanine Mosely's Bud can be found in the Tanteidan Convention Book 8. 'Fraid I can't help you get hold of a copy, though.

After inspecting the square/waterbomb base tessellation that John displayed at Bristol, I drew myself a crease pattern to help me understand it. I can't remember how many repetitions John had, but here's the pattern I came up with for a 16x16 grid. Think of each square as being at the centre of a twist-fold, and you should get it.

Thanks, I have become hooked on tessellations

Ok I figured it out myself. I was suspicious about it being one of the pictures shown in the album but I did not know exaclty which one since none has the name waterbomb base tessellation.

Excellent model and I had been looking for how to do it. Thanks Mark for that great Cp.

After posting the above CP, I realised that John actually folds this by using a grid that is set at an angle to the edges of the paper. I keep meaning to post an updated CP but have never got round to it... Anyway, the grid should be at a slope of 2 to 1. (Hope that makes sense!)

After I folded mine I was thinking that something might need to be cut form the borders for it does not seem to fit properly.

The 2 to 1 slope is notr clear, could you please explain? Or even better issue that revised Cp you have been thinking of?

I hope this silence from Mark means he is working on the cp :-) I am still trying to figure out the offset, I guess I now know what he meant but I still haven't tried in on paper. I guess the solution would be to have one of the corner of the square nstead of having it as it is now according to mark's cp, offset by one little square

I made a grid diagonally. The paper leftover on the sides is less now, but I think it can still be better.

My boss saw the piece lying around in my desk and asked "is that a pinneaple?" And she was right, the tessellation looks very much like pinneaple skin, it just lacks the top leaves to complete the whole fruit, so here's an idea for someone wanting to develop a new model, a pinneaple out of the waterbomb base tessellation.

Your wish is my command...

The light grey lines are for guidance only - they mark the centre of the square (obviously) and the quarter-points of two opposite sides. Begin by pinching the quarter points in order to locate the diagonal lines through the centre of the square.

I have thought about extending this pattern onto a long rectangle, so that it will wrap round on itself, but haven't actually done it yet.

Thanks a lot Mark. I would have never thought that a slope of 2 to 1 meant that.

I was interpreting your instructions as shifting the first waterbomb base to one corner of the grid and then doing the rest according to the pattern. Something like what can be found at: http://www.angelfire.com/co/cubo/Wbtess.html

AWESOME!

That rotated pattern fits neatly in the square. Check http://www.angelfire.com/co/cubo/rottess.html
Thanks again Mark

I think the tesselation and hydrangea models are there. It has illustrated step-by-step instructions. I hope that helps.

Right, so the final cube is 3x3x3 cubes.

Because you mentioned "tetris shapes" I thought you might be talking about the Soma cube because it is built almost completly with shapes that are made from four cubes. I've made Soma and Bedlam cubes with both Sonobe modules and business cards. Making a Steinhaus puzzle would be similar. I personally like the Soma cube because there are many other structures than can be built with the pieces.
