Hey guys,
After poking around the forums and getting in touch with Karl, I've started my project.
I've got 3 weeks to pull off three complicated origami forms for a client.
Here I will chart my trials and tribulations [img]http://www.c4dcafe.com/ipb/public/style_emoticons/default/smile.gif[/img]

Initially, here's the first and easiest of the forms I'm attempting. By the time I've nailed this I should have a good idea of how to do the others!

I'll post an update tomorrow when I've got something to show!

Or maybe I'll post a problem right now!
The straight forward bends are easy enough, I'm doing those with a bend deformer.
Now I've got to figure out a more complicated bend, I think it's the third fold in the video... as in the attached image.
I'm planing on doing only one side then mirroring that.
I'm playing around with joints, but haven't got it anywhere near right. Any suggestions welcome!

OK, it's been a busy and tiring week, so I haven't been posting updates as I go.
I have got my head around things now and I've used three different techniques so far. I'm looking to have the iris mostly finished by monday.
For the simple folds I'm using a bend deformer. I've tried using bones for the compound folds, but now I've settled on a slightly more complicated method that gives me more control. It's long winded story to explain, but involves pining vertex points with xpresso to nulls that track along a spline that follows the leading edge of the fold. I've attached a file if anyone's interested, look forward to any thoughts/feedback [img]http://www.c4dcafe.com/ipb/public/style_emoticons/default/smile.gif[/img]

I really like your solution, thanks for sharing. I tried something similar a few month ago, but without the blend to another spline to make the paper bend nicely.

Cool, thanks Space.
I'll be looking to re-use as many folds as possible to save me having to rig each one!

Hey there, thought I would post some further scene files.
Mostly I've been using the same method of pining points to moving nulls, though when the paper has more folds/thickness I've started to use the same technique with point clusters - the first time I've used them, really powerful! Also some of the thicker folds have been made with joints to get the folds to bend around a thicker radius. The morph tag has been invaluable to smooth out any problems along the way. I feel this projects a great back door into character rigging, something I've never really dabbled with before.

Very impressive stuff. I wish I understood more about how it is done. I really appreciate the inclusion of the C4D files which I am examining to try to understand more about how you are accomplishing the effect. I also appreciate the updates along the way. Thanks

Thanks guys.
Kellycat, for two out of the three files, most of the secret is in the xpresso - double click on the xpresso tag to bring it up.
It's pretty basic xpresso, nothing complicated at all, so perhaps a good intro if you haven't looked at it before [img]http://www.c4dcafe.com/ipb/public/style_emoticons/default/smile.gif[/img]

Nicely done... [img]http://www.c4dcafe.com/ipb/public/style_emoticons/default/smile.gif[/img] I'll take a look at the project file later today.

Peace,

Thanks Rich. TEARING my hair out with the current fold, my desk is littered with dissected paper flowers :(

Hi Nigel, I completely missed the xpresso tag. It looks pretty advanced to me, but I haven't experimented with xpresso yet so I really don't have a clue. At least I now have a better idea how it is done. Thanks again and good luck with the project.

Really amazing stuff!

I'm only just starting to realise the full implications of just how useful Xpresso actually is.

Can I ask where you cut your teeth? I am finding little bits and pieces that are all useful, but I don't suppose there's a one-stop-shop for Xpresso noobs?

Looking forward to seeing the finished product!

Cheers,

Nick

Hmmm, good question. The MAXON quickstart manual would probably be my first stop followed by the tutorials here at the cafe.
Base 80 has some great stuff.
Also check out here.
The best bet would be to kidnap Rantin Al and have him on hand to solve your problems whenever you need some magic!
On the update front, I've finished all the modeling and blocking in the animation. Now it's streamlining animation and setting up my cameras.

Latest update, with quick thoughts on texturing - though I haven't started that job properly yet.
