"folding" a base

[YHOYO]

hi how are you?

I want “fold” some draws… please check this… is oripa+blender:

- YouTube

If you see I need to assign two types of lines and press “fold”, but in blender that faces are overlapping and I need to move the fases and vertex in order to obtain a good render.

also I want some interaction… like this:

I don’t know if the easy and best option is convert oripa’s fold script to blender or execute that into blender … you can download the code file to folder here https://dl.dropboxusercontent.com/u/4230273/Folder.java

draw into blender is really easy

but folding that kind of model is really hard without an automatic script… and more with some like this:

what do you think???

best

In oripa it’s also overlapping and clipping in some areas. You can try to add a Solidify Modifier and render it with Post Processing Edges (or Freestyle).
But i have no useful hint for the “Interaction” (animation) of the Origami. Can Oripa animate the Complex Sheet you posted? i mean Gargoyle op. 75, your second image.

hi… Oripa don’t make animations, but rig simutqtor yes… Umm animation is not importantt… Bit the final order of faces yes.

I never found a solution for this kind of problem, since there is no way for blender to calculate the normals correctly as far as I know.
The closest I could get is using solidify and a transparent material (or you can try with volumes), but the solidify modifier can’t handle coplanar faces well …

For render you can use Wireframe modifier and 2 colors, paper color is shadeless semitransparent.

HI… THANKS FOR ALL SUPPORT

transparency and/or material aren’t a really solution… the really answere is calculate the real rotation of each face and the moving in 3d space…

some more ideas??
