Please help me for this crease pattern its very difficult http://www.h5.dion.ne.jp/~origami/e/rabbit.html

Hmmm, tricky one. I collapsed the base without too much trouble - or at least I collapsed a base, but I'm not sure it's right. I can't see how to get from the base I have to the rabbit in the picture - the front legs seem to go completely the wrong way.

Anyone else had a go at this?

I don't know what base Mark Leonard folded, but I had a go at this model and I collapsed a base. On another topic someone mentioned assigning direction to vertexes and I had my first try with the rabbit's CP, so why don't you try and and see if you can finish the model from the vertex assigned CP? For simplicity I only noted the convex vertexes with the ^ sign. The ones that are not noted should be assumed as concave.


Here's the URL for it:

I would have included the image directly into the posr but angelfire does not allow direct linking

Where is the article on vertex assignation? or can someone explain about to me?its the first time i heard about it =)

It is not an article, it is just a post on this same board at this threadhttp://snkhan.co.uk/phpBB2/viewtopic.php?p=2119#2119 the second post on that page. The author is wolf and it is just a proposal of some sort.

I wouldn't blame you if you gave up following that thread, as a little unpleasentness seems to have crept in...

I think the idea of vertex assignation is interesting, but I haven't really tested it out yet. It could be a significant advance in crease patterns, or it could be a dead end - at the moment I don't know which. I did make an attempt at the new version of the rabbit CP, but I ran into problems again. Unfortunately I think I threw away my first attempt, so I'm not entirely sure if these are the same problems as I had the first time, and I'm not sure whether the vertex assignations helped or not. I do know that I don't yet have a rabbit.

I can't tell if it's easier either, since I'd already attempted it without the vertex assignment. Anyway I think I got the same flat folded base.

There's a photo of the same rabbit on Gilad's website:

At least, it's listed as the same rabbit (the one from Tanteidan Magazine #53).

Mark, referring to your earlier post - assuming you've gotten the same base, I think the legs are simply valley folded down, and then narrowed with a rabbit ear (with the vertex of the rabbit ear pointing towards the front). This eventually does give you something that looks like the rabbit in the original photo.

After I made the vertex assigned CP I thought of another method that would be even easier to draw since adding that ^sign is not always easy when vertices are too close.

My idea was to put a color dot on the convex vertices and leave the concave ones untouched. See the same rabbit CP at

What do you think?
