Bad try to animate courved folding

Made with Maya and inverse kinematic bones. But it does not work realistic because the surfaces do not stay true to original. If somebody know how to make it right, please tell me!

Comment by dimensionaut on March 2, 2010 at 20:10: I'm curious about it.
Ive found a clip on YT by Tactom (Tomohiro Tachi) named "Design System for Rigid Quad Origami". It shows something very similar we talk about. I think you already know it. Also very interesting and I hope it will be available sometime.

Comment by Gregory Epps on March 1, 2010 at 23:10: I have created something to assign rulings to a crease pattern so it can run through Rigid Origami while in a workshop with StudioMode last wkend - will upload def soon (when I get it work in Rigid Origami...)

Comment by dimensionaut on March 1, 2010 at 23:05: I thought so. Surely it is possible to do it in Maya but I cant get on with my small skills.I'm more familiar with Rhino, so I try to realize it with Grasshopper. I'm a big fan of tomohiro tashi's "rigid origami" but sadly it does not work for my scheme. I'm still trying to create a definition that needs a crease pattern for input as well but it should be possible to control the intensity of certain areas. Does somebody tried something like that?

Comment by Gregory Epps on March 1, 2010 at 21:54: It is possible, but slow to set-up... much easier in Maya/grasshopper/GC. Solidworks is good for this type of linkage model because all lengths are constrained anyway - so the whole system is controlled from one angle contraint between any two linked faces; but not quick for setting up as to create this dual state model (3D and 2D) I had to re-build the 3D by mating every facet!

Comment by dimensionaut on March 1, 2010 at 21:47: interesting! is it also possible to animate the folding process in SolidWorks?

Comment by Gregory Epps on March 1, 2010 at 17:17: Have a look at the pics from SolidWorks I posted a while ago, they are basically the same idea as what you have - a linkage system - except that all lengths are constrained i.e. the sheet doesn't stretch. This could mean you don't need bones for the kinematics, as it is a one degree of freedom linkage.
