Paper folding

by Riccardo Bovo

Feb 18, 2011

Moved from Daniel Piker Video curved folding 

I've tried to develop a definition (without getting the same result)

even if the definition seems to work (with the mesh present on paper.3dm), the transition between the flat sheet and the curved fold sheet is not happening ...instead it looks like that the sheet just happen to get to the final shape without any plausible explanation...I'm kind of confused any help?

 

Thanks

Riccardo

    You need to somehow apply a force to move the paper out of a single plane.

    One simple way of doing this is to pull in 2 or more points with a variable length spring:

    Attached is a definition for this. I also increased the strength of your planarization force.

    There are many other ways of actuating the folding, such as moving anchor points, attraction forces, etc

    Eventually I do plan to put in more rotational forces like hinges that could drive the folding directly
