lightweight roof structural system

posted for Andrei due to filtering issues...

hi all !

i am looking for a structural system to build the roof on my thesis project.
a preliminary shape can be seen in the image below. ( don't mind the poles, they are probably gonna be branched or splayed towards the top )

please name a few structural systems that could be used to build the canopy. it has to be light (or fairly light), not necessarily cheap (it's a school project after all), and it can be opaque or transparent or anything in between.

hope you guys can help, thanks a lot for the interest!

The roof that comes to mind is the "TENSIL FABRIC ROOF SYSTEMS" used by modern architects in public buildings, for info and fabricators google "tensil fabric roofs"

Good luck
