Developable dome

Developable dome

An origami dome using a generalization of one of Ron Resch's folding patterns. Inspired by the work of Tomohiro Tachi (http://www.tsg.ne.jp/TT/cg/). An approximate solution is generated geometrically, then the 'developablize' force in Kangaroo is used to optimize it so that angles around each vertex sum to 360° (which they do to within 0.00003°)

Ok here is my definition.  Keep in mind it is just the basic Resch pattern not the Dome.  I used Daniel's simple origami definition to create this.

The linework at the surface edges needs to be post-processed to origami standard peak (solid) and valley (dashed) notation.  I hung up my origami career after I made a shirt out of a US dollar bill.  Go out on top, I say...

I've not actually tried folding this in real life yet. If anyone wants to have a go (it would take some patience!), here is the 3d model and flat crease pattern: generalized_resch.3dm

within 0.00003°  and you call this accurate???

ok just joking
