Origami Structure

Hi everyone !

I followed a lot of discussions on this website (and others...), trying to find a solution.

I have an origami cover-structure to build, composed of triangular forms and means, like. I downloaded a lot of definitions and the result is pretty good.

But my problem is that I need all the triangular forms similar, like a regular diamond pattern in a sheet of paper.

In fact my goal is in this conversation :

I try to find a way to get parameters for all diamonds (scale, angles...) and for my target surface (scale, twist...), but it's always a dead-end...

If someone can help me it will be very nice !

Best regards

Pablo
