Satoshi Kamiya - Ryu Zin (CP)

[Raptorex55]

Wouldn't that just be the actual Crease Pattern!?

[Kafar]

Accordnig to Wikipedia - pcp.

But seriously, pcp stands for progressive crease pattern, so it's few cps showing more lines each

[Froy]

Maybe

"partial crease pattern"?

[Raptorex55]

Partial Crease Pattern was my first guess, but Progressive makes a little more sense.

I've got six awesome sheets of Thai Unryu Paper that are going to go towards a large Ryujin 2.1. My question is this: double tissue or Tissue-foil-tissue?
I have the stuff to make double tissue but it will be a very time consuming process. Ive had great results with tissue foil, but it seemed a little on the thick side. (Although It was lotka-foil-Unryu.) Which one will work best?

[Froy]

Double tissue.

The foil use is much more delicate and demanding than simple papers (people is taking its use and power to get good 3d shapes too lightly) and for a model like the Ryujin in witch the paper will be turned over and over again you will end creating a lot of unwanted marks. Also remember that tissue foils is very hard to reverse crease marks orientation and this could make the folding of the head a serious pain.

[kareshi]

The problem with my mulberry tissue foil 2.1 was that it didn't bend well in the end. So I couldn't shape it to much more than a C. And the fuzziness of the paper made the head all blurry.

[Raptorex55]

Thank you Froy and Kareshi, you have confirmed my doubts about the tissue foil. I'll be using double tissue, though it will be time consuming to make such a large sheet.

Hello. I am in the progress of attempting to fold Ryu Zin 3.5 from Kamiya's CP in his latest book. Right now I have managed to collapse the head, I have found the eyes, the two long whiskers on the tip of the nose, the two big horns, the flaps for the tounge, upper and lower teeth, and the two "spikes" on the lower jaw.
But I am having a hard time figuring out:
1- where are the rest of the spikes along the side of the head? I think there are two long, and three short (I am thinking they are inside the head somewhere, and I have to do som wrapping/unwrapping, and then thinning by sinking) Some guidance/photos/pointers on a CP would help me a lot.
2 - How the h/%¤#¤ can i split the points for the teeth?

[phillipcurl]

just say hell. you won't get banned or anything.

1. if you look at CP, you'll find 3 points which aren't on the diagonal and will create those spikes. you must sink one of them and use 3 points as small horns. (I hope posting head cp isn't illegal)

big spikes are marked with pink, the similar flap to sink is marked with green, the small horns are marked with red. in total, 5 spikes - enough if you have folded 2.1 head, you'll see it is very similar, however the lowest spike becomes 3 smaller ones in 3.5.
and sorry for markings, which are only on one side - but head has diagonal symmetry, so I hope you won't get lost

2. that is hard to explain, but you must sink tip of a flap in the jaw and then you have two micro flaps, which have a 135 degree angle and you must narrow them and bend into correct position, so they create teeth.

Mmmm Didn't you noticed in the last page of the Ryujin article the image of the CP where Kamiya marks what point belongs to each part of the head. That's odd.

Thanks a lot! I will take my crumble of paper, uncrumble, and attempt the spikes/teeth. Good enough explanation for me.

Ugh, of course, now that you say it, I had to look up the article (p. 64) and, lo and behold, exactly what I asked for. Oh well, better to ask one time to many than on time to little. Actually I did not look up the article at all when I started my testfolds, only looked at the CP. "Some" time would have been saved if I had remembered to look up the article for the details I have been fighting to solve. (head horns and scales, and I havent even tried the 45 degree "thingy" in the neighbourhood of the feet). My "genious" solution for the scales are wrong!

As a sidenote, has anybody translated the relevant ryu zin pages to english? If so, are there any additional info besides the selfexplanatory images? My japanese is not quite up to standards...

Hi, Fjank, do you have a flickr? I am too from Norway I am also making ryu 3.5 too XD

[mikaorigami]

Makes us 3 norwegians who are at ryujin 3.5! I never met another serious norwegian paperfolder before so this is just great =D
