I want to take an icosahedron (a 20 sided object) and animate it to fold/unfold from a flat surface as if it were like Origami and being folded to make the shape.

Does anyone have any suggestions or might there be an existing solution on how to achieve this?

Thanks,
Frez

That is so impressive .. thank you Enviob!

I'll take a look to see what I can learn from it, however it's a slightly different effect than what I'm going for.

Here's a cube example online:

I did find this demo which is close to the idea, where instead of growing the poly's, the object is folded/assembled.

If there is a more elegant or controllable solution that let's one go from totally flat to assembled, I'm very interested.

Not very procedural, but… Maybe you can make an unfolded model, and edit this with the edit sop with snap to vertex to match an actual icosahedron.Then you can use blendshapes to do the transform.
If it were a bigger polyhedra it would be very dificult. But an icosahedron has only 12 points.
