Geometry - How to unfold a mesh?

nootropickint

Hi! I'm sure a lot of people here has already faced this problem, and processing gives us a lot of tool for doing it: toxiclibs, he_mesh, model builder, and many other.

So, How to unfold a 3d mesh? Something like the popular pepakura software: http://www.tamasoft.co.jp/pepakura-en/ Giving a 3d object, unfold it and print in a 2d paper.

I'm sure there are billions of way to achieve it so I'm asking for some advice on methodologies and/or ideas, but also other project that doing it, computational geometry papers, theory about it, anything Thanks!

Hi amnon, very nice example but it start from a mesh that is already a triangle string, I'm looking for something that can import any kind of mesh (like e triangulate standford bunny)

This is a nice project: http://hg.postspectacular.com/flatworld anyway it doesn't solve my problem. I'm on the way to implement it myself: basically the main problem is to find a procedure to create the minimum spanning tree that covers all the face of a mesh.

Why don't you use Pepakura? You can export your mesh as an .obj (http://n-e-r-v-o-u-s.com/blog/?p=3378) and import it into pepakura.

Yeah I've ended up in rewrite some kind of simplified pepakura.. just want it on linux...
