I have uploaded some images from the process of constructing the landscape for the Fuglane scenography, you can see it here as a slideshow.
I started off with a plastelina model (which I don´t feel like sharing with the world), and then continued with a google sketchup 3D model. I then got the model milled in styrofoam to use as the presentation model of the scenography. Later the 3d model was converted into technical drawings used by the skilled carpenters at the theatre to build a full scale version (about 10mx7m, the highest top about 1.6m). It was then covered by a material to make it more suitable as a projection surface.
I used a total of 4 projectors, two from above, one frontal, and one for the back wall. I used two macminis with matrox dualhead- to-go splitters and a customised version of my projection software VPT (not unlike the upcoming release).
Everything was controlled from the lighting console of the theatre, using an enttec dmx usb pro interface combined with Olaf Matthes excellent max externals.
